Yasir, CEO and solo founder of Chatbase, joins Saba and Charlie on the Napkin Math podcast to break down how he bootstrapped an AI customer support platform from a PDF chatbot side project to $10M ARR in just 3 years — starting before ChatGPT even launched. He shares the real story behind going viral, hitting $1M ARR in 4 months, the chaos of early growth, why he stayed bootstrapped, and how he thinks about building durable AI "harnesses" in a world where models improve every few months.
