Things I build.

Giving trust back to the internet. Developers integrate identity verification, proof of personhood, AML screening and fraud prevention through one API and SDKs — with a free tier that removed the price barrier the incumbents built their business on. We verify millions of humans across 190+ countries, and the product loop is fast: ship, measure fraud signal, talk to customers, ship again. This is where most of my time goes — end to end across product, code, distribution and customers. Profitable, multi-million dollar ARR, growing ~20% MoM with a tiny, obsessed team. Backed by Y Combinator (W26).

One of the biggest anti-aging businesses in Spain. We started as an aesthetic clinic, a med spa with a single location in Barcelona, and grew it into longevity: anti-aging protocols, hormone and biomarker optimization, my personal health obsession turned into a company. More than 10,000 patients have already visited us, rated 4.9 stars on Google across 700+ reviews. Now we're opening a new clinic in Madrid and our own lab-testing facilities — blood extraction, biomarker panels, lab infrastructure we control end to end. My role here is co-founder and high-level strategy; the day-to-day machine runs without me while my hours go to Didit. Profitable, doing $5M+ in annual revenue.

Our first company. We started with GPU farms mining Ethereum, then went deep into web3: blockchain protocols, a token launch, many smart contracts — and a metaverse. We were building Gamium as a decentralized metaverse with avatars and digital identity years before it was obvious that identity was the interesting part. Never found product-market fit and failed. The most expensive and most useful education we ever got.
