Consumer product

A customer orders, the product builds itself, the payment lands. In your business, that is your quote, your order or your follow-up running the same way.

Live since May 2025, without interruption, in French and English. I no longer develop it: it has been running and taking payments on its own ever since, which is the best test I could have put it through.

The idea

Commissioning a custom song cost hundreds of euros and took weeks. Music generation made the creative part a matter of minutes. Everything else still had to be built: capturing the intent, producing it, delivering it, getting paid.

What I built

A form that captures the occasion, the style, the emotion and a personal story. Then generation, delivery by email, and online payment. The customer fills it in, gets a preview, and pays if they like it.

How I found the users

Meta ads, out of my own pocket, with A/B tests on the creative. Two things I would not have learned otherwise: photos convert markedly better than video, and the real buyer is over 30. They are looking for a birthday or farewell gift, and what they actually want is personal stories about that person woven into the lyrics. The product was rebuilt around that.

What I decided not to build

Staying in B2B, where I am comfortable. I sell services to companies; I deliberately built a consumer product, in a market I did not know, to learn paid acquisition with my own money. Until I had paid out of my own pocket to acquire a customer, I would not allow myself to advise a client on it.
