Healthcare should be preventive, not reactive
At Lucis, we believe that healthcare should be preventive, not reactive. We're building the OS to help people add more healthy years to their lives.
Founded by Baptiste and Max, Lucis is building the health platform they wished existed: one that helps people anticipate problems before they begin.
Lucis is an AI-native company. Everyone on the team gets unlimited tokens and direct access to the best models.
Built by operators, for everyone
We're a team of repeat founders, engineers, medical experts and true missionaries united by a single mission: to help people stay healthy for longer. Passion for preventive health runs through everything we do.
Our founding team comes from Alan, Algolia, Instacart, Spacefill and Padoa - builders who have taken products from zero to millions of users.
Based in Paris, we're backed by YC (X25), top global VCs, athletes and the founders of Airbyte, Strapi, Sqreen, WePay, Plato, Veepee, Resilience and Zenly - all as obsessed with the future of human health as we are.
We've doubled in size over the past year and are doubling again. We're well funded, growing fast and building a team that matches the scale of our ambition.
If you're excited to move quickly on meaningful problems at the intersection of health, data and AI, you'll fit right in.
Side by side, moving fast
We work together from our Paris hub. We're passionate about what we're building and believe the fastest way to create something exceptional is side by side. We're open to relocation support for the right people, and we welcome team members who travel to work with us in Paris on a regular basis.
Rigour without ego
Audits, science, and code all deserve the same high bar.
Radical ownership
Feedback loops are short. Everyone contributes to building the best version of Lucis.
Velocity over perfection
We ship daily and prefer a good decision today over a perfect one next week.
We hire adults and treat them like owners
That means giving you the tools, the trust and the upside to do your best work.
Compensation
Competitive salaries and meaningful equity. When Lucis succeeds, you do too.
AI-native environment
Unlimited tokens and access to the best models. If it makes you faster, use it.
Full Lucis access
Full access to the Lucis platform for you and your family - from advanced blood diagnostics to AI-driven protocols. Dogfooding is encouraged.
Health & wellness
Comprehensive health insurance (where available) and a wellness stipend for the gear or supplements that keep you at your peak.
Flexibility
We offer the flexibility you need to go for a run on your lunch break or pick the kids up from school. Vacation time is generous and mandatory - burnout helps no one.
Continuous learning
Supported through books, courses and conferences. You'll be working at the intersection of AI, medicine and data, with access to experts and mentors across our investor network.
We're building a movement in preventive health, and movements happen in person.
