Griffin Dunaif
Griffin Dunaif is the co-founder and CEO of Halliday, a San Francisco blockchain startup building the first agentic workflow protocol - infrastructure that lets developers ship onchain applications without writing smart contracts. A Stanford computer science graduate (2023) who left to build, Dunaif started Halliday in 2022 as a buy-now-pay-later tool for gamers, then pivoted to the broader bet that workflows, not contracts, are how AI agents will safely operate onchain. The company has raised $26 million total, including a $20 million Series A led by a16z crypto in March 2025.
