Data beats narrative.
I studied Aerospace Engineering because complex systems fascinate me. Rockets, satellites, the kind of projects where failure is not an option. But halfway through, I realized what excited me most wasn't designing the parts — it was making the whole project work. The team, the direction, the decisions.
In 2017, I co-founded Stratolloon with Alex Caballero. We started with stratospheric technology and IoT for emergency services, then pivoted to satellite-data analytics for insurers and climate industries. Along the way, we earned recognition from ESA (2017 and 2018), the European Commission, Banco Santander, and Indra.
Awards and recognition are good credentials. But they don't build a business. When we saw the original product didn't have a viable market path, we made the hard call to stop. That decision shaped how I work today: be honest about what works and what doesn't. Separate signal from noise.
After that, I worked in data and innovation consulting — turning analysis into real business decisions and mentoring early-stage startups on finding actual use cases.
Today, as Head of Product & AI at GPTadvisor, I build generative AI tools for private banking and wealth management. More than ten major banks across Europe and LATAM use our platform. Thousands of advisors rely on it daily — with a 97.5% satisfaction rate and over 40% time savings.
I also build my own tools. sancho.vc tools offers tax optimization calculators for Spanish investors. Portfolio Stats helps retail investors analyze their portfolios. I enjoy making useful things that don't exist yet.
I prototype the idea. I sell the vision. I lead the team that builds it.
