Summary: billy, how we created our own e-commerce brand from A to Z
Wiiv is a branding, packaging and Shopify agency. But while we were supporting brands, we launched our own. Billy is an e-commerce brand created by the founders of Wiiv, built from scratch with the Deepbranding method, packaging designed for e-commerce, and a custom-developed Shopify. This article tells how we did it, what we learned, and what we couldn't have learned otherwise. Wiiv is based in Paris and operates in Bordeaux, Lyon, and Milan.
Billy: how we launched our own e-commerce brand (and what we really learned)
There's a difference between (thinking) you know how to do something and actually doing it. We wanted to know what it's really like to launch an e-commerce product brand. So we did it.
At Wiiv, we have been supporting product brands for several years. We build brand books, design packaging, and develop Shopify stores. We ask founders tough questions about their real target audience, their biases, their decisions. We challenge creative directions. We take strong positions on markets we know.
But at some point, we wanted to go further. Not just advise. To test. With our own money, our own brand, in a real market. That's how billy was born.
This article tells how we did it. In order. With honesty about what worked well, what surprised us, and what we learned that no client could have taught us.
Why launch your own brand when you're a branding agency
The short answer: to not "just" advise.
There's something particularly comfortable about the consultant role. You analyze, you recommend, you deliver. If it doesn't work, there's always a reason related to the client's execution, not the agency's strategy. This comfort is exactly what we wanted to avoid.
Launching billy means exposing ourselves to the same risks as our clients. Making the same difficult decisions with the same uncertainties. Spending real money on strategic choices we built ourselves. And measuring the results with the same indicators we ask them to track.
This is not a marketing stance. It's a way to be honest about what we truly know how to do and what we think we know how to do. The difference is often greater than we think.
What it changes for you as a founder: when you choose a branding agency, this simple question can change everything: have they ever launched a real product brand themselves? The answer says a lot about their relationship to risk and market reality. An agency that has never put its own money into a launch may have all the theories in the world. It doesn't have the intuition of what really happens when a product meets the market.
Market analysis before launching: what we really looked at
Honestly, we had at least 4 types of products in mind before launching billy, and the market analysis gave us the answers we needed. It's not that the others wouldn't have worked, but not in the same way.
Before creating anything for billy, we did the work we ask all our clients to do: an honest analysis of the product-market potential. Not a validation of our own intuitions. A real reading of the market.
The sector we had identified showed several positive signals. Existing and growing demand. Many low-end competitors, few in the premium segment. Interesting SEO potential for queries that no one was really addressing. And a product that could naturally generate content once we had resolved the specific communication constraints of the sector.
Competition in the premium segment was weak. This is often a positive signal because it means either the market doesn't exist yet, or no one has taken branding seriously yet. In our case, it was clearly the latter. The premium segment was open because no one had invested in a real brand identity. This is exactly the type of territory that strategic branding allows you to occupy.
The difficulty identified from the outset: communication constraints on advertising platforms. Certain sectors have strict restrictions on Meta and Google that limit dissemination. We knew we would have to build the branding by anticipating these constraints, not discovering them later.
What this changes for you: the product-market evaluation matrix is not an academic exercise. It's what determines the acquisition and investment strategy even before you start. A product with strong advertising constraints must invest heavily in SEO from the outset. A product with viral potential must build its packaging and unboxing to generate spontaneous content. These decisions are made before or during branding, not after. Our article on Deepbranding details the complete sequence.
Billy's Deepbranding: applying our own method to our own brand
We applied Deepbranding to billy exactly as we do for our clients. No shortcuts. No skipping steps because we "already knew" what we wanted to do. This is precisely the moment that taught us the most.
Founder analysis: what we discovered about ourselves
Too many founders arrive confident about these first steps; in a few minutes, we show them that it's not so obvious...
The first step of Deepbranding is founder analysis. We did it honestly. What we discovered: our motivations were fundamentally oriented towards benevolence rather than pure commercial performance. This conviction had concrete implications for everything else. It excluded certain marketing angles. It imposed certain choices of tone of voice. It defined red lines that we would not cross even if it would have been more profitable in the short term.
This is a perfect example of what founder analysis produces when done seriously. It's not a personal development exercise. It's a strategic decision that filters all subsequent decisions. A brand led by a founder who primarily seeks benevolence cannot do aggressive marketing. Not because it's forbidden. Because it's not sustainable in the long run.
The real target: the surprise we expected
Most brands have a useless, poorly defined, imaginary target. It's more of a fantasy than a reality. It's hard to move forward with that.
We expected to have a clear target. We were wrong. Or rather: we had a target in mind that wasn't the real market target. The competition addressed a specific portion of the population and completely ignored another. Our founders' conviction pushed us towards maximum openness. This choice was ambitious and complex to communicate simultaneously.
What this changed for branding: everything. An open and engaged targeting requires neutral visual codes, an accessible tone of voice, and communication that leaves no door closed. It's harder to execute than narrow targeting, but it's a defensible territory over time if the branding is done with precision.
The brand essence: why billy exists
We spent time on billy's Why. Not to have a nice phrase in a PDF. But to have a defensible conviction that we could apply to every decision: is this decision consistent with why billy exists?
The core conviction: to bring ease and fun into the daily well-being of every individual. This simple phrase has a direct consequence on every decision. It excludes everything that is complicated, anxiety-provoking, performative, or elitist. It demands lightness, clarity, and a reassuring tone.
What this changes for you: your brand's Why is not a statement of intent that you read once and archive. It's a permanent operational filter. Every communication decision, every new product, every partnership must pass this test: is it consistent with why we exist? If not, we don't do it. This discipline is what creates consistency over time. Without it, a brand drifts. Our article on what a brand book should contain explains how to document this filter.
Naming: why billy came after Deepbranding
We didn't know what the brand would be called when we started Deepbranding. That was intentional. Naming too early is one of the most common mistakes. We get fixated on a name before knowing what the brand really is, and then we try to make the branding fit the name. This is often the opposite of the correct sequence and limits branding reflections.
"Billy" came after we had defined the values, target, tone of voice, and brand essence. At that point, we were looking for something short, memorable, little used in the sector, and above all, consistent with the benevolence and approachability that characterized the brand. Billy sounds like a benevolent friend. Someone who wishes you well, who is always there, who doesn't judge. This is not an association constructed retrospectively. It's what we were looking for.
There were dozens of names on the table before we arrived at this one. More technical names, more cosmetic names, more premium in the classic sense of the term. All were eliminated because they didn't match what we had discovered about the brand during Deepbranding.
People love the brand name, and that's a great reward.
What this changes for you: your brand name must go through the same filter as all your other strategic decisions. Does it speak to your real target? Is it memorable without being generic? Is it adaptable across a range? Is it available as .com, .fr, and on priority networks? A provisional name is perfectly acceptable at the start. What's less acceptable is getting fixated on a favorite name before doing the strategic work. The name generation prompts in our brand book creation guide allow you to explore serious avenues.
Billy's branding and packaging: breaking all industry codes
There are 1001 ways to make good packaging, but millions of possible mistakes.
Once Deepbranding was complete, we had a clear conviction about what billy should visually project. And this conviction went against all the usual codes of the sector.
The central strategic choice: billy is a lifestyle brand before it is a cosmetic brand. No clinical codes. No packaging that looks like medical or pharmaceutical products. No serious and performative tone. Lifestyle, humanity, lightness.
This choice was not an aesthetic whim. It stemmed directly from the brand essence, the open target, and the benevolent tone of voice defined during Deepbranding. The visual direction was not "what we liked." It was "what was strategically consistent with everything we had decided."
Packaging: three contexts, one identity
In e-commerce, packaging works in three contexts simultaneously: the product photo on the product page, the advertising visual, and the reception experience. These three contexts have different and sometimes contradictory constraints, which is where you have to hold on and where deep branding is very useful.
For billy, there was even a fourth constraint: diffusion restrictions on advertising platforms. Certain sectors have strict limitations on the visuals that can be disseminated. The packaging therefore had to be strong enough to sell without resorting to direct visuals of the product in use. This is a constraint that forces the construction of a very strong visual identity, because it cannot rely on product demonstration to convince.
The information hierarchy on the main face was designed to work as a miniature thumbnail 80 pixels wide as much as in large format. The finishes were chosen to signal the premium level without needing the price. And the entire visual direction was validated in the context of an advertising feed before being finalized.
Even AI generations are unthinkable because they are limited on all intimate subjects... A very unexpected complexity.
What this changes for you: validate your packaging in the real contexts where your buyers will see it before going into production. Not just on a PDF mockup. On a real Google Shopping results page as a miniature thumbnail. In a real Instagram feed competing with other brands. In a photo received in a box. These tests cost nothing and avoid multi-thousand-euro redesigns. Our article on packaging that doesn't sell details all the most common problems.
Billy's Shopify: how far we pushed branding
Billy's Shopify was developed at level 3, meaning with custom modules developed specifically for the brand. We started with an existing theme to benefit from all native technical integrations, then added our own brand widgets.
The initial decision: to think about UX from the brand's perspective, not from the theme's. What are the moments in the customer journey where billy's identity should be expressed most strongly? Which standard sections of the theme limited this expression? And what to develop custom to fill these limitations?
The result: colors adapt to the product reference being viewed. Product pages lead into a universe, not a list of technical specifications. Humanity is present everywhere. The first thing you see when you arrive is not the product. It's well-being. A feeling. A way of being.
This is the most concrete test of how a branded Shopify produces something different: a visitor doesn't see an online store. They enter a universe. And in a universe, you don't compare prices with competitors. You buy or you don't buy, but the decision is made differently.
What this changes for you: the level of Shopify development must be calibrated to your stage of development and your brand ambitions. Not all founders need custom modules. But all need a Shopify that doesn't look like their competitor's. The first step is to choose the right theme and use it intelligently. Our article on the 3 levels of Shopify branding helps you choose the right level for where you are.
Launch: what was ready and what wasn't
We won't lie to you: everything wasn't ready for billy's launch. The fundamentals were in place: finalized brand book, validated packaging, operational Shopify, initial content created. But dozens of things remained to be built.
And that's normal. A brand that waits to be perfect to launch never launches. Perfection is a comfortable excuse not to expose oneself. What you need to have before launching are the fundamentals: a coherent identity, a defined tone of voice, a complete graphic charter, packaging that works for the brand, and an idea of future content. Everything else is built along the way.
What we learned about the launch itself: the first few weeks reveal things that no prior analysis could predict. Unexpected buyer reactions. Customer service questions we hadn't anticipated. Unexpected logistical issues. These learnings are valuable because they come from the real market, not from a hypothesis.
What this changes for you: launch as soon as the fundamentals are ready. Not when everything is perfect. The minimum checklist before launching: strategy and brand book completed and shared with all service providers, packaging validated in all e-commerce contexts, site consistent with packaging, minimum email sequence after registration ready, initial social media content in the right tone. If these few elements are in place, you can launch. The rest is built with real market data.
Billy's acquisition strategy: SEO, advertising, and specific constraints
The acquisition strategy was defined during Deepbranding, in the marketing levers section. And it was constrained from the outset by the reality of advertising platforms.
Advertising constraints: what we anticipated and what still surprised us
We knew before launching that certain sectors have advertising restrictions on Meta and Google. We had anticipated that billy would be in this situation. What we hadn't fully measured: the extent of these restrictions in practice.
Google Ads by default classifies us in a limited distribution category. This concretely means: fewer available placements, certain types of campaigns inaccessible, and a quality score that starts lower. This constraint reinforced our conviction to push hard on SEO from the start. When paid advertising is structurally limited, SEO is not an option. It's a necessity.
SEO: the decision to push hard and fast
We had identified during the initial market analysis that the SEO potential of the sector was real and underexploited. No one was seriously addressing informational queries around the topic. No pillar articles, no in-depth content, no visible editorial strategy among competitors.
So, we invested in SEO from the launch. In-depth articles, pillar content, thematic cluster structure. SEO is the most sustainable acquisition asset: it generates traffic even when you've stopped paying. And in a sector with advertising constraints, it's the most strategic investment we could make.
What this means for you: identify the acquisition constraints of your sector before launching and calibrate your strategy accordingly. If your sector has advertising restrictions, double down on SEO investment. If your product lends itself to organic content, build packaging and unboxing to generate natural UGC. If your market has low SEO competition, it's a window to exploit quickly before competitors see it too. Our article on the impact of branding on sales explains how these channels articulate.
AI in billy's daily life: what really works
Billy was one of the first brands where we tested the use of an AI-ready brand book in real conditions. Not as an experiment but as an aid and daily production infrastructure, it's our best assistant.
Claude (the AI) knows billy by heart. Not because we told it "this is an intimate wellness brand." But because we loaded the complete brand book, structured to be ingested by an AI: values with their operational definitions, tone of voice with authorized and forbidden words, target with its psychographic profile, promise with its concrete translations by support, in short, our entire brand book and our examples but specially formatted for an AI.
What this produces in practice: social media posts in billy's exact tone without re-briefing. Customer service responses in the brand's benevolent register. Product descriptions in three versions depending on the context. Creative briefs for photographers. AI does not make strategic decisions for billy. But it produces consistent content at high speed, and sometimes it reminds us when we stray from the guidelines.
AI only serves as our assistant. Despite seemingly "intelligent" responses, AI still cannot create sophisticated strategies or make important decisions.
We estimate that AI could handle approximately 80% of billy's customer service interactions without human intervention, while remaining perfectly in the brand's tone. For now, we have still decided to keep this part human and do it ourselves. But this is a concrete measure of what a well-constructed AI-ready brand book produces.
What this means for you: AI is only useful for your brand if it is fed correctly. A classic brand book uploaded to Claude or ChatGPT gives correct results. An AI-ready brand book (full text, dense, structured like a prompt) gives results that seem to come from someone who truly knows the brand. The difference is immediately visible in the quality and consistency of the outputs. Our article on the AI-ready brand book explains how to structure this document.
What we learned that we couldn't have learned otherwise
These are the real lessons from billy. Not the principles we already applied in our client projects. The discoveries that only a real launch could produce.
The imagined target and the real target always diverge. We knew it in theory. We experienced it in practice. Billy's first buyers taught us things about our real target that no prior analysis could have revealed. But that's normal, initial theory is meant to be only 80% accurate, the rest must adapt as you go. Obviously, the practical information fed into communication and content adjustments that we never would have made without real data.
The goal of initial strategies and branding is to be 80% realistic. The market holds surprises that cannot be anticipated.
The tone of voice is tested through customer service contact. The brand book defines the tone in theory. Customer service reality tests it in practice. A response to an aggressive comment, a refund requested abruptly, an awkward public question: these situations reveal whether the defined tone of voice is truly internalized or just put on paper. For billy, the tone of the benevolent friend withstood these tests. Not because we had a rule. But because we had a conviction.
AI can become your best friend when it comes to maintaining a tone of voice in a difficult and unexpected discussion. Unlike us, it has no emotions, just guidelines.
Cross-channel consistency is an ongoing discipline, not an initial decision. Maintaining consistency across packaging, website, social media, emails, and advertisements requires continuous vigilance. Every new service provider touching the brand must read the brand book before producing anything. Every new piece of content must pass the consistency test with existing content. Without this discipline, a brand drifts in a few weeks.
And it's great to experience it firsthand, it allows us to better understand deviations and help you avoid them in the future.
Constraints are opportunities for differentiation. Billy's advertising restrictions forced us to invest heavily in SEO and build a visual identity capable of selling without direct product demonstration. These constraints produced stronger and more original branding than we would have achieved without them.
Our strategies are always based on pushing your strengths rather than filling weaknesses. We gain time, energy, and power: an unfair advantage.
What this means for you: the most valuable lessons come from the real market, not from prior analyses. Launch with the fundamentals, measure the signals the market sends you, and adjust. This learning cycle is what builds strong brands. Not initial perfection. If you want to know where your branding stands before launching or relaunching, the free branding diagnostic provides an objective external reading in a few minutes.
Billy today: what it changed at Wiiv
Thanks to billy, we were able to measure the impact of branding in reality, encounter difficulties we hadn't imagined (budget management, logistics, etc.) and daily challenges. It's great and allows us to be even closer to our clients, their needs, objectives, and difficulties.
Billy is not just a brand. It's a permanent laboratory for Wiiv. Every new Shopify feature we want to offer our clients, we test it on billy first. Every new AI content approach, we experiment with it on billy before recommending it. Every adjustment to the Deepbranding method is fueled by what we learn managing a real brand in real time.
What it changed in our client projects: we ask different questions. Not "what is your target?" but "what have your first buyers taught you about your real target?". Not "what do you want to project?" but "what are you able to sustain over time, under pressure, in contact with the real market?".
These questions come from what we experienced with billy. Not from what we read.
Frequently Asked Questions
Why does a branding agency launch its own brand?
To never advise from the comfort of someone who has never taken the risk of launching. Billy allows Wiiv to test its own recommendations with real money, in a real market, with real performance indicators. An agency that has never put its own money into a launch may have all the theories in the world, but it doesn't have the intuition of what really happens when the product meets the market. This difference changes everything in how we support our clients.
How has billy changed the Wiiv method?
By confirming certain hypotheses and invalidating others. We learned that the imagined target and the real target always diverge in the first few weeks. That advertising platform constraints must be integrated into branding from Deepbranding, not discovered after launch. That the tone of voice is proven through customer service contact, not in a document. And that cross-channel consistency is a daily discipline, not a decision made once. These learnings have fueled concrete adjustments in how we support our clients.
Does billy's AI-ready brand book really work?
Yes. Claude knows billy in depth thanks to the AI-ready brand book we loaded for it and which is regularly updated. We estimate it could handle 80% of customer service interactions autonomously while remaining perfectly in the brand's tone, even in difficult or unexpected situations. We have chosen to keep this part human for now, but the potential is measured and real. This is a concrete measure of what a well-structured AI-ready brand book produces, and it is directly applicable to any brand that has done this work seriously.
What lessons from billy are directly applicable to any product brand?
Several, and they apply to any sector. Honest market analysis before branding: competition in premium segments is often weaker than one might think, because no one has yet done the identity work. Naming after Deepbranding and not before: a name chosen too early constrains strategic thinking. Packaging validated in all e-commerce contexts: mockup, thumbnail, advertising feed, reception. Shopify designed from the brand and not from the theme. Acquisition strategy calibrated to the real constraints of the sector. And the AI-ready brand book as an infrastructure for producing consistent content at high speed.
How does the market analysis you did before launching billy work?
We applied our own product-market evaluation grid: product attractiveness, target precision, market size and dynamism, underlying trend or fad, SEO potential, ease of marketing, possible margins, level of competition. What convinced us about billy: the premium segment was open because no one had done real branding. The SEO potential was real and underexploited. And the product could naturally create content, provided the specific distribution constraints of the sector were resolved. We also had at least four other product ideas in mind initially. The analysis gave us the answers we needed to make an informed choice.
How to manage Meta and Google advertising restrictions in certain sectors?
By anticipating them during Deepbranding, not by discovering them after launch. For billy, Google Ads automatically categorizes us into a limited distribution category, with fewer placements and certain types of campaigns inaccessible. The strategic response: double down on SEO investment from the start and build a visual identity strong enough to sell without direct product demonstration. Platform constraints are not bad luck, they define the acquisition strategy. Ignoring them at the branding stage creates costly problems a few weeks after launch.
Why did you choose SEO as the priority channel for billy?
For two combined reasons. Firstly, the advertising constraints of the sector structurally limited the reach of paid campaigns. Secondly, a clear market observation: no one was seriously addressing informational queries related to the topic. No pillar articles, no in-depth content, no visible editorial strategy among competitors. It was a real window, and we exploited it quickly. SEO generates traffic when you've stopped paying, making it the most sustainable acquisition asset in the long term, especially in a sector where advertising is restricted.
How did Deepbranding influence billy's packaging decisions?
Directly and on every aspect. The lifestyle positioning before cosmetic came from the brand essence. The visual codes that broke with the sector came from the open target and the benevolent tone of voice. The information hierarchy on the main face came from the analysis of the three e-commerce contexts of packaging: thumbnail product sheet, advertising visual, reception experience. And the choices of premium finishes came from the price positioning built during Deepbranding. No graphic decision was made before these strategic foundations were laid.
What was truly ready at billy's launch and what wasn't?
The fundamentals were ready: finalized and shared brand book, packaging validated in all contexts, operational Shopify, first social media content in the right tone, start of post-registration email sequence. What wasn't: many operational, logistical, and content things that are built as you go. And that's normal. A brand that waits to be perfect to launch never launches. The first few weeks reveal things that no prior analysis can predict, and these learnings are worth more than a few extra weeks of preparation.
How does billy use AI daily?
Claude is loaded with billy's AI-ready brand book, which allows it to produce in the brand's exact tone without re-briefing each session. In practice: social media posts in billy's benevolent register, product descriptions in three versions depending on the context (ads, product sheet, SEO), customer service responses in the benevolent friend's tone, creative briefs for photographers. AI does not make strategic decisions and does not replace human judgment on important issues. But it produces consistent content at high speed and sometimes reminds us when we stray from the guidelines. Our article on the AI-ready brand book explains how to structure this document to obtain this result.
How is billy's Shopify different from a standard Shopify?
It was developed at level 3, with custom modules created specifically for billy's identity. We started from an existing theme to benefit from native technical integrations, then added custom brand widgets. Colors adapt to the product reference consulted, product sheets take you into a universe rather than a list of characteristics, and the human element is present everywhere. The first thing you see when you arrive is not the product, it's a sense of well-being. This approach is detailed in our article on the 3 levels of Shopify branding.
What is the difference between a standard brand book and billy's AI-ready brand book?
A standard brand book is designed to be read by humans: laid out, airy, pleasant to browse. Billy's AI-ready brand book is designed to be ingested by an AI: full text, dense, formulated like a giant prompt, structured so that Claude extracts exactly the right information in the right order. The result is an AI that produces in billy's exact tone, with the right words, the right forbidden words, and the right target, without needing to be re-briefed. The difference between the two is immediately visible in the consistency and relevance of the outputs produced.
How does Wiiv support brands that want to create their own identity from A to Z?
At Wiiv, a branding and packaging agency based in Paris with operations in Bordeaux, Lyon, and Milan, every project begins with Deepbranding: the 11 strategic steps that precede any visual decision. Design then follows, as a translation of what has been decided. Packaging and Shopify stem from the identity built upstream, not the other way around. Billy is living proof that this method works in a real market. The online quote tool allows you to obtain an estimated quote calibrated to the project in a few minutes, and the free branding diagnostic provides an initial objective reading of the brand's status.
