https://trigger.dev/ lets developers add AI agents to their products with a simple SDK, handling execution, long-running workflows, and reliability so they don't have to. Over 90% of their usage now comes from agent workflows, and they recently announced their $16M Series A led by Standard Capital. In this episode of Founder Firesides, co-founders @mattaitken and @maverickdotdev sat down with YC's @koomen to talk about three versions of the product before finding product market fit, how building async infrastructure for two years accidentally put them in the perfect position for the agent era, and why they think the future of computing is programmatic checkpoint and restore - freezing and resuming compute on demand.

In this episode of Founder Firesides, co-founders @charlieholtz and @jacksondecampos sat down with YC's @aaron_epstein to talk about cycling through a dozen ideas before landing on the one that stuck, how building dev tools for themselves led to Conductor, and what they've learned from watching the best engineers in the world work with coding agents every day.
