Cosmian has secured backing from the PSL Innovation Fund to advance products based on inventions from multiple French research institutes including PSL-hosted Inria.

France-based data encryption technology developer Cosmian today closed a €1.4m ($1.7m) seed round co-led by PSL Innovation Fund, the deep tech-oriented VC vehicle aligned to the Université PSL ecosystem.
Venture firm Elaia Partners co-led the round both through PSL Innovation Fund – which it manages on PSL’s behalf – and through its venture capital vehicle Elaia Delta Fund.
VC fund Acequia Capital and family office Financière de Blacailloux also invested in Cosmian, together with angel investors including Florian Douetteau, Julien Lemoine, Guillaume Amblard and Marc Jalabert.
Founded in 2018, Cosmian builds data security products that exploit advanced methods of encryption to allow the client to continue working on the secured data without compromising access to intruders.
The approach should in theory enable data calculations to be safely conducted in potentially malicious environments.
Cosmian’s platform was created in partnership with a team led by David Pointcheval, director of the computer science departments across Université PSL’s digital science-focused research institute, Inria, as well as the École normale supérieure and the French National Center for Scientific Research.
