Chicago, Illinois, U.S.A-based S2G Investments has closed a USD 1 billion (EUR 854 million) fund after receiving investments from both new and existing institutional investors.
S2G Investments launched its ocean strategy in 2020 with a USD 100 million (EUR 85 million) fund devoted to investing in early, venture, and growth stage companies in the blue economy space. S2G Managing Director of the Oceans Investment Team Larsen Mettler told SeafoodSource in 2025 that the fund is devoted to investing in four main areas: ocean data, blue foods, maritime decarbonization, and blue biotech.
The new fund, dubbed “Solutions Fund I,” is not specifically devoted to the ocean strategy but will back growth-stage companies in North America and Europe across “core systems that power the world’s economy,” S2G said. That includes investments in food and agriculture, energy, and oceans, which can include energy infrastructure, maritime transport, agricultural inputs, and industrial electrification, it said.
“This fund expands our ability to provide the growth capital required to commercialize transformative technologies at a pivotal moment in the global economy,” S2G Managing Partner Aaron Rudberg said of the new fund. “By investing at the seams where food, energy, and ocean systems intersect, we see opportunities to accelerate solutions that are both economically superior and more resilient than legacy models. We are grateful to our investors for their support, which allows us to back operators scaling the companies that this moment demands.”
S2G said the new fund already has USD 300 million (EUR 256 million) invested across 10 separate investments, which “often fall outside traditional capital markets.”
S2G has also invested in a number of seafood companies, including Chilean aquaculture tech firm Oxzo.
“The fund’s strategy prioritizes businesses that strive to strengthen food and energy security and deliver positive environmental and human health outcomes, positioning them to build durable competitive positions and achieve market growth,” S2G said.
S2G said with the closing of its latest fund, it currently has USD 2.8 billion (EUR 2.4 billion) in assets under management and has invested in more than 120 companies since it was created.
