Revent VC Research
Investment Thesis
Revent (also known as Revent Ventures / Revent Capital) is a Berlin-based specialist impact venture fund founded in 2020 by Otto Birnbaum, Henrik Grosse Hokamp, and Dr. Lauren Lentz. The firm's thesis is that the combination of purpose and profit amplifies performance, and that the next generation of extraordinary companies will harness technology to solve system-critical problems that improve human lives and planetary longevity. Revent backs "ultra ambitious founders" building generational companies with defensible, highly scalable technology across three core impact pillars: Health and Wellbeing, Economic Empowerment, and Sustainable Planet. For an investment, the firm looks for conviction that a company can reach $100M ARR and become an "impact fund returner" within a decade.
Sector Focus
Revent explicitly organizes its thesis around three verticals:
- Health and Wellbeing — products and services revolutionizing how people manage health and receive care (digital health, chronic disease management, diagnostics).
- Economic Empowerment — companies expanding access to and reducing the cost of education and finance, and modernizing learning/training for the digital age.
- Sustainable Planet — products and services enabling more conscious, sustainable consumption and production choices for businesses and consumers (climate tech, energy transition, circular economy, agtech).
Stage Focus
Revent invests at Pre-Seed and Seed, occasionally extending into Series A follow-ons for existing portfolio companies (e.g., Series A/B participation in Sylvera, Avelios, Net Zero Nitrogen).
Check Size
Typical initial ticket size is €500K–€3M. External sources (Dealroom, Waveup) also cite a broader historical range of $200K–$2M for early checks, consistent with a pre-seed-through-seed strategy with reserves for follow-ons.
Fund Status / Recent Activity
Revent has raised at least two funds: an initial ~€50M Fund I (2020/2021) and a €100M (~$109M) Fund II, which closed around April 2025 (per Vestbee, April 10 2025) to back European startups across the firm's three impact pillars. The firm is actively deploying. Recent activity includes a new investment in Science Machine (autonomous AI agent for biomedical research, $3.5M, July 2025) and a pre-seed lead in Powernaut (€2.4M, December 2024). Numerous portfolio companies have also raised follow-on rounds from other lead investors (Net Zero Nitrogen led by World Fund/Azolla Ventures, Avelios led by Sequoia, Tem Energy backed by Atomico, Carbonpool, Farmless co-led by World Fund/Vorwerk Ventures).
Portfolio Highlights
Revent's public portfolio (from its website) spans over 20 companies, including: Avelios (hospital/EHR workflow software, backed by Sequoia at Series A/B), Sylvera (carbon project ratings, raised a €51M Series B led by Balderton), Electricity Maps (real-time grid carbon-intensity data API), Tem Energy (renewable energy transaction platform, backed by Atomico), Forward Earth (AI-driven supply-chain decarbonization), Atmen (hydrogen/e-fuel certification), Mirantus (specialty/eye care access), Granular Energy (hourly renewable energy certificates), Apiday (ESG data collection SaaS), Resourcify (waste management/recycling platform, raised €14M led by Vorwerk Ventures), Oska Health (digital chronic kidney disease management), Powernaut (energy portfolio optimization), Carbonpool (carbon-credit-denominated insurance), Magnotherm (magnetocaloric cooling technology), Net Purpose (portfolio impact-tracking data), Farmless (fermentation-based food production decoupled from arable land), Atmo Cooling (climate tech for desert regions), Noscendo (pathogen-detection diagnostics), One.Five (materials innovation from lab to market), Net Zero Nitrogen / NZN2 (biological alternative to synthetic fertilizer), and Tomorrow (impact-focused digital banking).
