BUILT BY
CHAMPIONS
Where Olympic gymnastics expertise meets Stanford engineering
Our Mission
Make elite coaching methodology accessible to every coach. Reduce the friction of programming so coaches can focus on what they do best: coaching. The same system used to develop Olympic medalists and World Champions, now working alongside you.
Co-Founder & CEO
RUBÉN LÓPEZ
Rubén is an Olympic gymnast with 25 years of elite training experience. As a coach, he has developed World Champions, Olympic medalists, and NCAA champions. His training methodology, refined at the highest levels of international competition, is the foundation of every WarmApp program. From periodization to skill progression, every detail reflects decades of elite coaching expertise.
Co-Founder & CTO
JEREMY BISCHOFF
Jeremy is a former USA National Team member, 4× NCAA Champion, and Stanford computer science graduate. He built the technology and systems powering WarmApp, combining world-class athletic experience with Silicon Valley engineering.
THE STANFORD CONNECTION
Rubén and Jeremy met at Stanford, where Rubén coached Jeremy and the Cardinal to an NCAA national championship in 2024. One was an Olympic gymnast and elite coach from Spain, the other a USA National Team gymnast studying computer science. Together, they shared a vision that elite coaching methodology shouldn't be locked behind closed doors.
WarmApp is the result. The same programming system used to develop World Champions and Olympic medalists, now accessible to every coach. World-class gymnastics expertise meets technology built out of Stanford.
OUR VALUES
What drives everything we build
Methodology First
Every workout is grounded in structured coaching methodology, not generic fitness templates. The AI builds from the same system behind World Champions.
Trust Over Hype
We'd rather be the tool coaches rely on quietly than the one that overpromises. If the AI recommends an exercise, it can explain why.
Expert System
Curated by an Olympic gymnast, not crowdsourced. Coaches trust the system because the methodology is real, tested, and transparent.
Education as Value
WarmApp doesn't just generate workouts. It teaches. Every prescription comes with reasoning, every exercise with coaching context. Coaches call it 'graduate school.'
Built for Coaches
Purpose-built for the people who program workouts, not a generic fitness app with AI bolted on. Every feature solves a real coaching problem.
Simplicity
As little design as possible. One AI colleague, one workflow, one place for everything. Complexity is the enemy of coaching.
