We’ll keep tracking his recovery after race day using our novel proteomic biomarkers. Athletes like Matthew push the human body to its limits. That gives us a rare window into how it adapts, performs, and recovers. We’re so proud of you, Matthew. Here’s to many more!

Seeing elite competitors use it to understand their aerobic fitness was a great validation of what we're building. Our mission is simple: bring the human performance lab to an easy blood draw, so athletes at every level can train and improve with real data instead of guesswork.

Built on cutting-edge proteomics technology and validated against thousands of lab-grade maximal exercise tests, our blood test goes beyond oxygen to map the unique molecular signatures of fitness from biologically meaningful proteins in the blood.

Wearables are useful for showing you what happened, but not what's happening underneath - is the body actually adapting in useful ways, or not?
