In Europe, many startups addressing climate change, societal health, and economic inequities face a critical challenge: limited access to early-stage funding, particularly from impact-focused venture capital. Revent addresses this gap by investing in mission-driven founders who use technology to drive systemic change, merging purpose with profit to scale solutions for planetary and societal well-being.
Today, Revent, a specialist VC for founders solving mission-critical problems, announces Fund II, a €100 million vehicle for early-stage European companies focused on societal and planetary health. Building on its first fund’s success, Revent supports companies that deliver exceptional financial returns while driving crucial transitions toward a healthier, fairer, and more resilient future.
The fund is backed by prominent LPs, including the Otto Group, Goldbeck, Arendt Oetker, and Wepa Ventures, institutional investors like the European Investment Fund, and leading European entrepreneurs behind companies such as Amboss, Urban Sports Club, and Oviva.
“We built Revent for founders who don’t just want to build a big company, but also want to build an important company – that is, a company that brings us a big step forward toward a better future. We look for exceptional people with this ‘dual ambition’ to do something big AND important, in areas such as the energy transition, industrial decarbonisation, healthcare, and reskilling, amongst others”, said Lauren Lentz, Founding Partner at Revent.
Behind Revent: A new paradigm of combining “purpose and profit”
Revent was founded in 2021 by Otto Birnbaum and Dr. Lauren Lentz, who bring extensive experience in venture capital and impact-driven initiatives. Birnbaum previously built and led the seed investment practice at Partech in Germany and worked at HelloFresh. Dr. Lentz brings expertise in impact measurement, policy, and analysis, with degrees from Yale, Harvard, and Oxford, plus professional experience at McKinsey and USAID.
Based in Berlin, the firm focuses on early-stage investments across Europe. Its mission is to support founders who use technology to tackle systemic challenges in climate change, societal health, and economic empowerment. Revent demonstrates that entrepreneurial success can align perfectly with social and ecological impact, creating a new model that unites purpose with profit.
Revent attracts exceptional talent driven by dual ambitions. Through Fund I, this focused strategy has led to several notable investments: Avelios Medical, a Munich-based health tech firm developing a new healthcare operating system, backed by Sequoia; Tem Energy, an energy software company helping businesses secure long-term competitive renewable energy rates, supported by Atomico; Sylvera, a London-based creator of reliable carbon credit ratings, with funding led by Balderton; and Granular Energy, a Paris-based company offering 24/7 energy source verification, recently backed by Norrsken.
Revent has achieved exceptional results, ranking in the top 10% according to Cambridge Associates’ global VC benchmarking.
Fund II and its “Real Value Framework” (RVF) to assess long-term value
Building on Fund I’s top-decile performance, Fund II introduces the “Real Value Framework” (RVF) — a new approach to evaluating investments’ long-term societal value creation. This proprietary tool helps estimate investments’ human and natural capital potential, incorporating these factors into investment decisions.
“With the Real Value Framework, we can estimate the economic value a startup can generate for society. We look for companies that can generate more than €100M per year of value for society and grow to more than €100M in revenues within 6 to 8 years. These companies will generate exceptional financial returns for our investors,” says Otto Birnbaum, Founding Partner at Revent.
Revent also partners with EU bodies, implementing regulations like the Corporate Sustainability Reporting Directive (CSRD), ensuring alignment between policy frameworks and private capital initiatives.
