💡 TL;DR – I’m a Spanish product-builder & repeat founder who loves shipping useful (sometimes downright fun) software.
Co-founded fintech Capchase (> $1 B deployed) and the non-profit Exponential Fellowship (helping top young Spaniards join US startups). In my spare time I hack on OSS tools, bots, and date-pickers, invest in promising founders, and write detailed handbooks so teams know exactly how I work.
Madrid-based “builder at heart.” Formally an Aerospace engineer, I gravitated to software because it lets you invent at the speed of thought. Today I split time between leading Product at Capchase, mentoring Exponential Fellows in SF & NYC, and tinkering on side-projects that scratch my curiosity itch. You can read more about me here.
- Capchase – Co-founder (2020-present). Deployed >$1 B in non-dilutive capital, processed $80 M in SaaS deals, team ~80 across 10 countries.

Over the next 5 years I’ll keep scaling Capchase, grow the Fellowship to 100+ alumni, and back ≥ 20 technical Spanish founders as an angel. Building in the US ecosystem lets me compound learning, capital, and network—fuel I’ll ultimately redirect toward Spain’s tech renaissance.
