Maelstrom invests across venture, liquid, private equity, and public markets, targeting infrastructure companies and assets it sees as foundational to the next wave of trustless decentralization. It backs high-conviction opportunities from early-stage equity and token investments through to private and public market positions, offering portfolio companies the experience, relationships, and resources drawn from having built one of the crypto industry's first profitable unicorns.
