Tensor Ventures

Tensor Ventures is a Prague-based, Luxembourg-domiciled deep-tech venture capital firm founded in 2018 that invests in frontier technologies and sustainable innovation across Central and Eastern Europe and beyond. The firm focuses on sectors it describes itself as fluent in: artificial intelligence, quantum technologies, computational biotech (techbio), semiconductors and sustainable and space technology. It participates in Seed and Series A rounds, sometimes leading and sometimes co-investing with trusted partners, and sources deals through proprietary methods including university referrals and partnerships with corporates such as Intel and NVIDIA. Tensor's first fund deployed roughly EUR 18.5M to EUR 20M into about 20 startups over four years and ranked in the top 20% of VC funds; in October 2024 it announced a second EUR 50M deep-tech fund, with the European Investment Fund committing EUR 20M, allocating roughly half its capital to Czech startups and half globally. Seed investments have averaged about $1.66M round size and its three Series A rounds around $16.5M. Across a portfolio of about 27 companies, notable holdings include Heartbeat.bio, Stacktape, Quantagonia, Antiverse, Anari.ai, Beit, QC82, DYNANIC and exits Neuronix and ultimate.suit. The firm is led by founders and general partners Martin Drdul and Roman Smola, with Petr Ulvr leading business development. Its most recent disclosed deal was leading a roughly $4M seed round in London-based enterprise-app modernization startup AppFactor, announced in January 2026. Tensor Ventures pairs deep-tech specialization with strong university and corporate sourcing across the CEE region.
