35+ Deep Tech Investors From CEE and DACH Looking for Visionary Founders

deep tech investors

While deep tech may be building the future, investors have not traditionally queued at its door. These potentially game-changing technologies come with too much risk and long windows of return for the majority of European investors. Yet as deep tech becomes instrumental for tackling today’s biggest challenges, we see increasing commitments from both public and private financiers. In fact, European deep tech is not only amassing more capital every year, but may be the second highest VC-funded sector, after energy, according to research for Q2 2023.

Central and Eastern Europe, a small overall market, nevertheless has a great potential for science-based breakthroughs, shown by recent R&D investments in the member countries, as well as an increase in deep tech funds. On top of that, public funding from the EU also helps in building venture funds and investing in disruptive technologies that may be too risky for private investors. 

What are the underlying trends for the increasing appetite for deep tech in the region? Stay tuned for an in-depth analysis in the following days.

Today, we take a closer look at some of the most active CEE and DACH-based deep tech specialist funds, as well as a few generalist funds with a strong preference for IP-driven businesses, and which have shown interest in Central and Eastern European founders.
