About Balaji Srinivasan
Balaji Srinivasan trained at Stanford, where he earned a BS, MS and PhD in electrical engineering and an MS in chemical engineering. He taught statistics and bioinformatics there, and his online Startup Engineering course drew more than 250,000 students in 2013, according to a timeline on The Anthology of Balaji.
He co-founded the clinical genomics company Counsyl in 2008. He later co-founded the company that became Earn.com, formerly 21.co, which began as a Bitcoin mining startup and became a paid-messaging network. Fortune reported that Coinbase bought Earn.com in 2018 and that he then became Coinbase's CTO. He was also a general partner at Andreessen Horowitz. He is a co-founder of Coin Center, the crypto policy nonprofit, and wrote The Network State.
He is now based in Singapore and founded the Network School, which he announced in 2024. It is a program for founders and technologists focused on crypto, longevity and building startup communities. In July 2026 Malaysian authorities revoked the licence for its Forest City, Johor campus, and he has since announced an MOU with Kazakhstan for a new campus. He has said the school was not shutting down, and the Malaysian licensing dispute is reported in the press.
The Anthology of Balaji timeline dates the start of his angel investing to 2013. Crunchbase lists his personal investments well above 100, and the count keeps growing. Crunchbase also shows him in recent seed and pre-seed rounds, including Physical Superintelligence (seed) and Dirac Labs (pre-seed).
Third-party sources name other well-known companies among his investments, including OpenSea, Perplexity, Starkware and Alchemy. We have not confirmed investment dates or round details for those. Crunchbase shows no lead investor on the rounds visible on his profile, which suggests he usually joins rounds led by others. Founders should confirm this directly.
