About Giacomo

I'm a passionate investor and tech engineer. Italian-American, based in Frankfurt, and today building Awalyt as Founder and Product Owner.

My path didn't start in finance. Born in Naples in 1993, I studied Aerospace Engineering at Università Federico II and graduated with top honors (110/110 cum laude). I started my career on the technical side, where precision wasn't optional, and over time moved into management and business roles.

In parallel, investing became more than a hobby. I studied it on my own for years — academic papers on portfolio theory, fundamental analysis, the Bogleheads literature. The issue I kept running into wasn't a lack of information. It was the absence of one place where a serious investor could pull everything together. The tools I wanted were scattered across too many platforms, and most of them felt cold and technical, hard to approach unless you already knew exactly what you were looking for. I wanted something more human. A real platform, not a collection of disconnected tools.

Awalyt started as something I wanted for myself. It grew into a product I thought other serious investors would want too.

The goal is simple. Give you data you can access, understand, and actually use — even if you don't have years of investing experience but you want to learn, improve, and make decisions based on numbers rather than opinions. Investing is a long-term game, and the tools you use should reflect that.

Awalyt is built around a few ideas I genuinely believe in. It should be transparent. You get to see the data and the method behind it, not just the conclusion. It should help people understand what they're actually doing with their money, not hand them a number they have to trust on faith. Making mistakes is part of investing for everyone — what matters is being able to learn from them and do better the next time. And a normal investor, without years of experience, should still be able to read the results and make a real decision on their own.

Always open to talking with other founders, investors, and advisors.
