Phantom

Phantom made its name as the go-to self-custodial crypto wallet for the Solana network and has since established itself as a leading wallet provider across most major blockchain networks. Founded in 2021 by Francesco Agosti, Brandon Millman, and Chris Kalani, Phantom now reports more than 15 million monthly active users who custody roughly $25 billion in cryptocurrencies. 

The San Francisco-based company is valued at $3 billion according to its last raise in 2025. Big-name investors—including Sequoia Capital, Paradigm, Andreessen Horowitz, and Variant—all took part in that $150 million funding round.
