Keith Putnam-Delaney is the co-founder and CEO of Primer, a San Francisco B2B marketing intelligence platform that turns work-email lists into ad-platform audiences, enriches leads, and orchestrates campaigns across ad networks, social, and sales tools. A former high-school history teacher who became a growth marketer at Dropbox and Eden before founding Primer, he built the company from a consulting hunch into a venture-backed startup that raised a $12M Series A in 2022.
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.
Eric Bailey is a Boston-based accessibility advocate, designer, writer, developer, and speaker. As a staff designer on GitHub's Primer design system, he works to make component libraries genuinely usable for people relying on assistive technologies. He is the longtime lead redesigner and maintainer of The A11Y Project, has published more than 200 articles across publications like CSS-Tricks, Smashing Magazine, and the GitHub Blog, and is a fixture on the conference circuit. His guiding line: if it's inaccessible, it is neither radical nor revolutionary.
