European semiconductor investors

Only two funds carry a verified semiconductors line on this desk – both real and useful, but a thin universe worth flagging.

Supernova Invest

Seed to industrialisation, deep tech including semiconductors Paris, France (Grenoble office) €800M+ AUM across 8 funds

A deep tech venture platform born in 2017 from CEA Investissement, France's atomic and alternative energies commission, in partnership with Amundi and Credit Agricole. Gives it unusually early sight of laboratory spin-outs from Grenoble. Writes €1-3M seed cheques up to €8-30M for late-stage industrialisation.

Why it is hereThe largest fund on this desk, with a fully disclosed ticket range spanning seed through industrialisation.

PhotonVentures

Early development to scaling, photonics specifically Hilversum, Netherlands Founded 2023

A Dutch fund investing in photonics companies from early development through scaling and exit, across AI, communications, security, robotics, healthcare and quantum. Positions itself inside the European photonics supply chain for proprietary deal flow.

Why it is hereThe only fund on this desk built specifically around photonics rather than semiconductors broadly.

This is one of the thinnest investor desks on Sesamers by fund count, despite active recent semiconductor rounds (EUCLYD, iPronics, TUSK IC) – a clear priority for further sourcing.
