Clira Health is building an at-home blood monitoring platform for high-risk hematology patients, founded by a repeat founder and an AP-HP transplant nephrologist tackling a hard problem with broad clinical impact.

Patients with acute leukemia or undergoing stem-cell transplantation often need several blood tests each week. We are developing a fully automated system that painlessly collects and analyzes a blood microsample at home, starting with CBC + CRP.

Our long-term goal is to move beyond static blood measurements toward high-frequency biomarker monitoring, enabling care teams to intervene earlier and, ultimately, anticipate complications before they become critical.

We are an early-stage, venture-backed medtech company based in Paris, with offices and laboratory space inside Saint-Joseph Hospital. We build our technology in-house, from blood collection to analysis.

We are looking for people with high agency, intensity and very high standards, who love hard technical problems and learn by building.
