Multicoin Capital
Multicoin Capital is a thesis-driven crypto investment firm founded in 2017 by Kyle Samani and Tushar Jain, investing in cryptocurrencies, tokens, and blockchain companies and protocols believed to be reshaping trillion-dollar markets. The firm runs a hybrid structure of a hedge fund (its multi-billion dollar Master Fund, investing in public markets, direct positions, and strategic sales) alongside several venture funds that back early-stage companies, with venture checks ranging from roughly $1M to $50M. Its Venture Fund III closed at $422 million in January 2022. Multicoin invests across open and decentralized finance (DeFi), blockchain infrastructure and Layer 1/Layer 2 protocols, decentralized physical infrastructure networks (DePIN), stablecoins and payments, real-world asset tokenization, wallets, identity, gaming, and crypto-native consumer applications, with a well-known concentration around the Solana ecosystem. The firm's phoenix logo symbolizes a new financial system rising from the ashes of the old one, reflecting its long-term, high-conviction approach to absolute returns across market cycles. Headquartered in Austin, Texas, Multicoin manages capital on behalf of family offices, foundations, endowments, and institutional investors. In February 2026 co-founder Kyle Samani stepped back from day-to-day management, with operations continuing under co-founder Tushar Jain and partner Brian Smith.
