German VC Revent closes €100M fund to back European startups in climate, health, and sustainability

Berlin-based VC Revent has raised its second fund of €100M to invest in early-stage startups across Europe. 

  • Otto Birnbaum and Lauren Lents established Revent in 2021. Since then, the fund has invested in 26 companies, including AI-powered hospital platform Avelios Medical and Granular Energy.
  • Revent will write €500,000-3 million cheques into 34 pre-seed and seed-stage startups, with half the fund reserved for follow-ons. 
  • The fund will focus on startups accelerating the energy transition, improving healthcare systems for greater efficiency, and leveraging AI to enable personalized, value-based healthcare. Additionally, it will support new technologies that promote more sustainable industries and supply chains.

"Especially in times of uncertainty which we have seen unfortunately rather often in the last years wether it was Corona, Ukraine war or today Trump's trade war, we will remain ever more focussed on long-term value creation by investing in critical data and software infrastructure required for the large transitions stemming from demographic & climate change," Otto Birnbaum commented.

  • Despite market headwinds and political uncertainty — particularly in the US — Revent closed Fund II in just six months. 
  • LPs include the European Investment Fund, the German retail giant Otto Group, Dr Oetker, Hymer, and several prominent European tech founders. Lentz says the fund's broader thesis resonated with LPs looking for climate alignment and diversified impact.
