About us

Founded in 2022 by Isabelle Amiel, Sienna Venture Capital is a leading European investment firm, targeting early growth technologies.

Our team has been collaborating for over a decade, launching multiple global funds and initiatives in the tech sector.

Sienna Venture Capital emerged as a spin-off from these earlier successful ventures.
