Synthos Green Energy raises $130M from Polish entrepreneurs for SMRs

A single reactor project costs billions, so this capital signals confidence from Poland's business elite rather than funding construction.

• Synthos Green Energy (SGE) raised about $130M (500 million zloty) in an angel round from Polish entrepreneurs including InPost founder Rafal Brzoska and ElevenLabs co-founder Mati Staniszewski, the largest angel round on record in Poland's energy sector.
• Founded in 2019 by Polish billionaire Michal Solowow, SGE is developing small modular reactors based on GE Vernova Hitachi's BWRX-300 design to help cut Poland's reliance on coal power.
• Foreign investors have separately pledged about $350M, pushing total committed capital to roughly $462.5M, with Solowow saying the overall round could reach €800M by year-end.
• SGE's joint venture with state refiner Orlen, Orlen Synthos Green Energy, is targeting 2032 for its first reactor at Wloclawek, slipping from an earlier 2030 timeline Solowow cited in May.
• Solowow is weighing an IPO for SGE around 2028 after a second funding round, while also leading a UK consortium planning 14 BWRX-300 reactors across three sites worth an estimated £35 billion.
• With a single BWRX-300 reactor estimated at $2 billion to build, this raise buys equity stakes and credibility rather than construction funds, underscoring how private capital is testing nuclear bets as Europe seeks low-carbon baseload power.
