Keiretsu Capital LLC, founded in 2013 and based in Seattle, manages investment funds that grant accredited investors and limited partners access to co-investment opportunities drawn from the Keiretsu Forum Angel Investor Network. As the exclusive global affiliate of Keiretsu Forum, the firm taps into a network of over 3,000 angel investors across 50 chapters. Since its inception, the combined entities have backed more than 300 portfolio companies and deployed over one billion dollars in funding. The firm’s goal is to deliver consistent returns by supporting companies from early growth stages through later rounds.
Keiretsu Capital focuses on three main investment vehicles: co-investment funds, real estate fund access and blockchain fund of funds. Capital commitments typically range from one million to five million dollars, often arranged alongside family offices, institutional investors and crowdfunding syndicates. The firm’s team brings two decades of experience in technology, health-care, financial services and real estate investments, applying rigorous screening processes and thorough due diligence drawn from its affiliate network.
Investments in clean technology and battery innovation play a significant role in Keiretsu Capital’s strategy. The firm has supported battery storage companies and related material developers through its co-investment vehicles. Examples include Joule Case, which develops modular battery systems for solar backup and mobile power; Ni-CAT, focused on advanced lithium cathode materials assisted by artificial intelligence; and Soteria Battery Innovation Group, which designs safety solutions to prevent lithium-ion fires. Broader environmental-tech engagements include companies working on carbon utilization in construction materials and engineered surfaces for industrial sustainability.
