Granit raises $6m to free healthcare professionals from administrative work - Seedcamp

Healthcare professionals train for years, only to spend a growing share of their time on admin.
Much of that work is fragmented and repetitive. More than eight in ten European clinicians say admin work cuts into the time they can give patients. It’s thankless work, and every hour spent on it is an hour spent away from patients.
Granit want to give healthcare workers that time back. We’re proud to lead their $6M first round.
Founded in March 2026 by Jenny Mansour and Corneille Maréchal, Granit develops AI agents that connect directly to existing business software (electronic patient records, specialty software) and to external platforms (complementary health insurers, national health insurance, accounting), and take on the administrative work teams do by hand today: invoicing, follow-ups, correcting claim rejections, checking coverage.
Crucially, Granit integrates into systems healthcare workers already use, with no need for complex technical integration.
The early results back this up. Granit was founded in March 2026 and already works with more than 250 healthcare organisations across France.
The team bring deep expertise in French health policy and healthcare operations. Jenny worked on health policy in government before joining BCG and later running the health business unit at Galileo, Europe’s largest private higher education group. Corneille was the first employee and founding engineer at Apiday.
Jenny Mansour, CEO of Granit, said: “We don’t want to add one more piece of software to healthcare professionals’ already saturated daily lives. We want the tools they already use to work for them, not the other way around.”
Felix Martinez, Partner at Seedcamp, said: “Fragmented, routine admin work takes up far too much of already overstretched healthcare workers’ time. Granit’s agents take that work on inside the systems staff already use, freeing up more time for patient care. Jenny and the team bring deep, rare expertise across healthcare policy and technology, and we couldn’t be more excited to lead their first round of funding.”
This funding will allow Granit to accelerate the development of new healthcare verticals, strengthen its technical and commercial teams, and kick-start its expansion into several European countries.
