Ankur Goyal is the founder and CEO of Braintrust, an end-to-end platform for building AI apps. Before that, he founded Impira, a data management platform that was acquired by Figma, where he went on to lead the AI team. Ankur kickstarted his career when he dropped out of college to join the founding team at SingleStore (formerly MemSQL), a formative experience that shaped his views on building for high-bar users.
In today’s episode, we discuss:
• Ankur’s early lessons on quality from MemSQL
• How frustration with evals at Figma led to Braintrust
• Why they delayed go-to-market (on purpose)
• How to find product-market fit in a new market
• Why building great software comes from a place of “paranoia”
• And much more…
