Matterwave Ventures spun out from btov Partners in 2022 as a dedicated Industrial Deep Tech fund, focusing specifically on hardware-heavy frontier technologies for industrial and climate applications rather than general deep tech investing. The fund connects technical founders transitioning from research institutions to venture-backed companies with European industrial networks, particularly targeting technologies that blend industrial performance with sustainability goals.
