Bill Bishop

Bill Bishop appears in Founder Mode: Chris Best, Founder & CEO, Substack as Substack’s first real user. He wrote Sinocism, a China-focused newsletter that already had an audience and demand before Substack supplied the connected publishing, email, and payment infrastructure.

In Chris Best’s account, Bishop’s launch produced about $100,000 on the first day and changed the Y Combinator interview from a zero-revenue application into a live demand signal. Best also says Bishop remained Substack’s biggest customer for years, which made the case powerful but not automatically repeatable.
