Five Years, Five Products: A Solo Founder Retrospective

Five years ago, I built my first web application. It was ugly, buggy, and served no one.

Today, I have five active products: Aviation Infinity, ClickAi, New Pilot Milano, Babonbo, and Want To Be a Pilot. They serve users across multiple countries. They generate revenue. And I still build them alone.

What Worked

Consistency. Not motivation, not inspiration, but consistency. Building every week, shipping every month, learning every day. The compound effect of consistent effort over five years produced more than any burst of intense work could have.

A consistent tech stack. Every product uses the same foundation. This eliminated learning curves between projects and let me build faster with each new product.

Domain expertise. Building for industries I understand (aviation, travel) produced better products than building for industries I was learning about. The domain knowledge is the unfair advantage.

Low costs. No office, no employees, serverless infrastructure that scales with usage. Low costs meant survival during the COVID downturn and freedom to build during recovery.

Portfolio approach. Multiple products across multiple markets provided diversification that saved me during the aviation crisis of 2020.

What Didn't Work

Building without validating. Some products (Comensalaqui, Brojure) were well-built for markets that didn't support them. I should have validated demand before investing months of development.

Under-pricing. I consistently charged too little. Every price increase improved both revenue and customer quality. I should have priced higher from the start.

Avoiding marketing. I'm a builder, not a marketer. I spent too much time on product and not enough on distribution. Better products don't automatically find larger audiences.

Doing everything myself. The solo founder approach works up to a point. Beyond that point, the lack of complementary skills (design, marketing, sales) limits growth. I'm approaching that point.

What I'd Tell Year-One Me

1. Ship faster. Your first version is never as bad as you think.
2. Charge more. Price communicates value. Low prices attract the wrong customers.
3. Build for people you know. Domain expertise is your biggest advantage.
4. Save more cash. You'll need it during the unexpected downturn.
5. Write about what you build. Content compounds like code. Start a blog from day one.

Five years is a long time and a short time simultaneously. Long enough to build meaningful products. Short enough that the best building years are still ahead.

Year six will be about scaling what works, cutting what doesn't, and exploring the new directions that five years of experience have made visible.
