history >


I was born and raised in Granada, Spain πŸ‡ͺπŸ‡Έ.

As a kid, I built stuff, played basketball and typed. Yes, I spent a lot of time writing I-don't-remember-what in a typing machine.

When I was 13, my dad got his first computer, which got me from typing into coding: Modula-2, Bash, C, Linux Kernel, etc. When we eventually got an Internet connection at home, I went all in with Perl, PHP and IRC bots.

At 18, I enrolled in University of Granada to study Computer Science.


While at University of Granada, I got a scholarship to study one year at University of Miami πŸ‡ΊπŸ‡Έ. Neither me or my parents had ever travel abroad before, so this was... quite the deal.

I had a freaking good year abroad at University of Miami, where I specialized in AI and pool parties.


Getting closer to my graduation, I got a scholarship offer for a PhD in AI in Miami. After a tough time making a decision, I rejected it. Why? I realized I enjoy building & shipping much more than doing research, so I moved back to πŸ‡ͺπŸ‡Έ to join a nascent AI startup (IActive) as the 4th software engineer.

IActive built a low-code SaaS for domain agnostic resource planning with AI, specifically leveraging a proprietary Hierarchical Task Network (HTN) planning implementation.

During my 4-year tenure at IActive, we raised $3M+ and grew the team 10x. Unfortunately, the company was eventually shattered by the Global Financial Crisis where the budget for innovation in Spain was cut to 0.


In 2012 I moved to Rio de Janeiro πŸ‡§πŸ‡· to co-found Nativoo as CTO.

Nativoo, which is still live, is an AI-powered travel planner in your pocket. Our vision was to become an intelligent version of Tripadvisor: based on your preferences and usage, Nativoo creates custom itineraries in less than 5 seconds. The product leveraged an evolution of the AI technology that IActive developed.

We raised money from Sbtur, a Brazilian travel group. After a 3-year attempt at a global plan, some countries were not working as good as we expected. We scaled back to just focus on the Brazilian market. Nativoo was eventually absorbed by Sbtur and I stayed with them for 6 months before leaving the company and Brazil.


In 2016 I moved to San Francisco πŸ‡ΊπŸ‡Έ to co-found Vivo Fitness as CTO.

Vivo started as a meditation app based on audio guides, like Calm or Headspace but with a social component. Over time, we pivoted into all of wellness and Vivo became a personal trainer and a nutritionist in your headphones.

We raised $1M from NFX and other angel investors. After 3 years, in 2018 ClassPass acquired Vivo. We explored different exit opportunities. We chose ClassPass because of the people and the vision under an increasingly competitive digital fitness space.
