Granit has raised €5 million in pre-seed funding, led by Seedcamp.

Granit was founded in March 2026 by Jenny Mansour and Corneille Maréchal.
Evertrace spotted Corneille Maréchal, co-founder of Granit, 221 days before the funding announcement.

On 29 March 2026, Evertrace detected the first signal of company formation for Corneille Maréchal. That was 221 days before Granit's funding announcement.
Jenny Mansour is the company's CEO. Before Granit, Corneille Maréchal was a founding engineer and engineering manager at apiday.
What they’re building
Healthcare professionals spend a growing share of their time on administration instead of patients. Granit's agents work inside the software and insurer portals that care teams already use, such as AmeliPro and Doctolib, and run the billing cycle from eligibility checks and pre-authorisations to insurance claims, follow-ups on rejected files and matching incoming payments.
Setup takes a few days and needs no heavy technical integration. The company says its agents are already used by more than 250 healthcare organisations in France.
The round
The €5 million round combines €3.5 million in equity, led by Seedcamp, with €1.5 million in non-dilutive financing that includes Bpifrance. Drysdale Ventures, Rerail, Purple Fund, Cleo Ventures and Kima Ventures also backed the company. Granit will use the funding to cover new healthcare verticals, grow its technical and commercial teams and start expanding to other European countries.
