Our story

For over a decade, Isabelle, Thomas, and Mikaël have been investing together to foster growth and innovation in the tech sector. Their journey began in an investment holding co-founded by Isabelle, where they played pivotal roles in launching several successful venture capital funds and invest in 70+ tech companies.

This collective success led to the founding of Sienna Venture Capital, combining their expertise and partnership with GBL to support disruptive technologies and visionary founders.

We follow disciplined investment criteria, typically investing $5 to $10 million in early growth and growth-stage companies, leading or co-leading rounds, while serving as trusted and approachable advisors to the businesses we support.
