A letter from the founders

Your biology.
Your whole life.

We built Santé because understanding your body should feel like a beginning.

Alejandro and Alberto Rosas together, twin brothers and co-founders of Santé Labs
Alejandro & Alberto Rosas Twin brothers. Co-founders. Barcelona.

More numbers.
Or more understanding?

We are Alejandro and Alberto. Twin brothers, curious about health and the lives we want to live.

For us, a laboratory report should open a conversation. It should help you understand what was measured, how it connects to the rest of your body, and which questions are worth asking next.

Too often, the numbers arrive without that connection. Your blood test is in one place. Your history is somewhere else. Your questions begin just as the appointment ends.

We believe those things
belong together.

That is why we are building Santé. Careful testing. Clear explanations. Your history in one place. A way to return to the questions that matter to you.

We want every step to feel considered: choosing a panel, preparing for the draw, reading a result, and deciding with your care team what comes next.

A shared curiosity

Twin brothers.
One belief.

You deserve to understand the body you live in.

We are starting in Barcelona, with a laboratory experience that makes room for the person behind the sample.

One considered step at a time.
