ELYO

We built ELYO for ourselves, first.

Quentin Amalvy and Sacha Peretti, the two founders of ELYO

We believe everyone deserves to train like a pro. Not just those who can afford it. That belief is what drives us to build ELYO.

Quentin

I wanted to run a marathon. I downloaded a generic plan and a running app. But that program wasn't suited to my situation. Six weeks later, I was injured. I looked for a coach, but the prices were out of my budget.

Sacha

We had already been building software together for two years. So we started building a tool for Quentin, to read his training data and help him plan his week. That's where ELYO began.

Quentin

I ran that marathon. And we kept improving the tool for months. Talking with other runners, cyclists, swimmers and triathletes, we kept hearing about problems we knew well: understanding your numbers and fitting your training into your life.

Sacha

We wanted the data to be useful for something concrete: understanding a workout, deciding what to work on and adjusting the plan when the week changes. With follow-up that also remembers how you felt and what you talked about.

Quentin

Today, we use ELYO ourselves for our training. We read its answers, look at what really helps us and rework what isn't precise enough. We're building the coach we want to find after a run.
