Function Health for Europe

What is your company going to make? Please describe your product and what it does or will do.

We combine medical expertise with AI to turn regular blood tests into clear, actionable health insights. Our product helps people across Europe understand their health better and make smarter choices to live healthier and longer lives. It's designed to be simple for consumers but backed by real clinical knowledge and data.

Where do you live now, and where would the company be based after YC?

We live in Paris, Île-de-France, France, and plan to base the company there after YC as well.

Explain your decision regarding location.

We're rooted in Paris where we have access to medical networks, AI talent, and a growing digital health market in Europe. Moving elsewhere would disconnect us from these strengths and our early users.

Is this the real Lucis YC application?

No. Y Combinator keeps submitted applications private. This is a reconstruction: the real YC form questions, answered from Lucis's public data (launch notes, founder backgrounds, product description). It shows how a company like Lucis would present itself to YC, not the text they submitted.
