I’m just starting my journey of building things that enhance health, fitness, and longevity.
Currently, I’m spending my time on Kaizen Hybrid, NAU and a few secret ventures. Occasionally, I drop a tweet about it.
Most recently, I co-founded Product Hackers School, a pioneering school in digital experimentation and growth. We taught the latest marketing and product methodologies to some of the biggest companies in Spain and Mexico.
We bootstrapped that rocket to 4.000+ students in just 3 years, hiring incredible talent, acquiring another company, and keeping the business profitable—while having a blast along the way.


Then It was time to move on.
I realized I wanted to dedicate my time to missions that help people live healthier lives.
Building in health takes time, resources, and—more than anything—a ridiculous amount of bureaucracy. So, in the meantime, I’m focused on fitness, developing apps that take a holistic approach to performance across multiple disciplines.
My goal? Bringing the Renaissance individual into the modern fitness world.
That’s why Kaizen is launching soon.

But that’s not all.
In my free time, I’ve been mentoring startups through Tetuán Valley, Santander X or BackFund.
Oh, and I’m also having fun running with Almería Run Club, preparing for my first Marathon in Norway and lifting almost every day at Summit Fit Club.
