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, NetZeroNitrogen).
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 and 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 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 biopharma quality control, $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 (NetZeroNitrogen backed by World Fund/Azolla Ventures, Avelios Medical led by Sequoia, Tem Energy backed by Atomico, CarbonPool, Farmless co-led by World Fund/Vorwerk Ventures).
Portfolio Highlights
Revent's public portfolio spans over 20 companies, including: Avelios Medical (hospital information system software, raised $31M Series A/B led by Sequoia), Sylvera (carbon project ratings, raised a $57M Series B), 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 (industrial compliance/certification for renewable fuels, raised €5M), Mirantus (non-medical eye care access), Granular Energy (hourly renewable energy certificates), Apiday (ESG data collection SaaS), Resourcify (waste management/recycling platform, raised €14M), Oska Health (digital chronic kidney disease coaching), Powernaut (energy portfolio optimization), CarbonPool (carbon-credit-denominated insurance), Magnotherm (magnetocaloric cooling technology), Net Purpose (portfolio impact-tracking data), Farmless (fermentation-based food production, raised $4M), Noscendo (next-generation-sequencing sepsis diagnostics), One.Five (AI-powered packaging platform), and NetZeroNitrogen / NZN2 (biological alternative to synthetic fertilizer, raised funding covered by TechCrunch July 2025).
