About

We partner with European deep-tech founders at seed stage to turn groundbreaking ideas into world-changing companies.

Investment approach

Thesis
At ACT Venture Partners, we invest in the early stages of deep-tech, when the science is promising, the market is still forming, and the belief is not yet widespread. From quantum communication to AI-powered biology, from climate infrastructure to advanced sensing, we partner with technical founders who turn hard science into real-world impact. We exist to catalyze that transformation.Source (opens in a new tab)
Ownership target
Our initial investments typically start at Seed rounds with ticket sizes of up to EUR 1.5mn and ideally between 10% to 20% equity.
Eligibility
We primarily invest in Europe
Traction requirement
We don’t wait for traction, we invest on conviction.
Investing status notes
In 2024, we continued expanding our portfolio with investments in Qubitrium, Meddenovo Drug Design, Nextmol, and Rototip
