Ethan Chan
Ethan Chan is the co-founder and CEO of Allium, a New York and Singapore based company building the system of record for onchain finance. After leading machine learning and data engineering teams at Primer and lecturing at Stanford, he turned to the unglamorous work of cleaning up blockchain data, translating raw events from 150+ chains and 10,000 protocols into standardized, finance-ready datasets used by Visa, Stripe, Coinbase, Uniswap and Phantom. He cheerfully calls himself the Chief Data Plumber.
