Chicago’s S2G Investments Closes $1 Billion Solutions Fund I

Chicago-based multi-asset firm S2G Investments announced it has closed its Solutions Fund I at $1 billion, making it one of the largest pools of capital for venture in the entire Midwest. The growth-stage fund will back companies in food and agriculture, energy, and oceans, primarily across both North America and Europe.

The fund drew commitments from pension funds, funds of funds, and family offices across the country, as well as Europe, Asia, and Australia, according to the announcement. 

S2G says $300 million has already been deployed across ten investments, with the firm targeting what it calls the "Missing Middle" - the financing gap between early-stage venture and infrastructure-scale capital for businesses ready to scale.

Founded in 2014, S2G reported $2.8 billion in assets under management as of the announcement, and says it has invested in more than 120 companies since inception. Its team of more than 60 is led by managing partners Aaron Rudberg, Chuck Templeton, and Sanjeev Krishnan.

"This Fund expands our ability to provide the growth capital required to commercialize transformative technologies at a pivotal moment in the global economy," Rudberg said in a statement. "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."

The fund's existing investments include Urbint, an AI-enabled software company helping energy utilities manage field risk that was recently acquired by Itron — the fund's first exit. Other named investments include ANA Inc., developer of the EBOSS hybrid generator system that integrates battery storage; Exacto, an agricultural input specialist based in Madison, Wisconsin; and Echandia, a maritime battery supplier currently working with San Francisco Bay Ferry on a zero-emission ferry network.

S2G says its three target sectors represent over $7 trillion in annual global trade and roughly 90% of global emissions reduction potential, with the firm noting that these impact statistics were provided by portfolio companies as of December 31, 2025 but have not yet been independently verified.
