David Gu Built a Company Out of the Pager That Wouldn’t Stop
After three years of midnight pages and invisible infrastructure work, David Gu stopped treating the backend as a burden. He and Amanda Zhu turned it into Recall.ai, the conversation-data layer they had once wished someone else would build.
Recall.ai
Recall.ai is a San Francisco developer-infrastructure company that sells a universal API for capturing meetings. Instead of building brittle bots for Zoom, Google Meet, Microsoft Teams, Webex, Slack Huddles and in-person calls, developers make a single API call and get back recordings, transcripts, and rich participant metadata. Founded by University of Waterloo dropouts David Gu and Amanda, the company pivoted from a consumer meeting app into the plumbing beneath a wave of AI notetakers and sales tools, and now powers thousands of companies. Recall.ai is Y Combinator-backed and raised a $38M Series B at a reported ~$250M valuation in September 2025.
