ACT Venture Partners

ABOUT US

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.
ACT is a registered Alternative Investment Fund Manager (AIFM) under EU regulations and complies with the Invest Europe professional standards, including valuation, reporting, and transparency guidelines.

Who We Back
We partner with scientists, engineers, and operators, who know their domain better than anyone else and are driven to build something transformative.

We look for a proprietary technical insight or scientific moat, a market shaped by irreversible change, the ability to attract talent, learn fast, and scale wisely. You don’t need a polished deck. You need the courage to build from first principles.
