Conviction

Contrarian Ventures is a Vilnius, Lithuania-based seed and Series A venture capital firm focused exclusively on climate and energy technology, investing in founders who are developing the technologies and business models that will accelerate the global transition to net-zero emissions. The firm was founded in the Baltic region with a particular interest in the Central and Eastern European climate technology ecosystem alongside broader European investments. Contrarian invests with initial checks from $500,000 to $3 million, often as the first institutional capital entering a company, and focuses on energy transition sectors including sustainable fuels, carbon removal, renewable energy systems, industrial decarbonization, and nature-based solutions. The firm's name reflects a deliberate orientation toward contrarian investment opportunities: markets and technologies that the broader investment community has overlooked or underestimated, where genuine scientific promise and insufficient capital create an opportunity for outsized returns from early, conviction-based bets. Portfolio companies include Aerleum, a sustainable aviation fuel technology company; CarbonBlue, focused on ocean-based carbon dioxide removal; Emerald, a climate technology company; and Nord Fuel, a company working on sustainable fuel solutions. Beyond its original investments in Aerleum, CarbonBlue, Emerald, and Nord Fuel, the portfolio includes additional European and global climate technology companies.
