How Bing Wu built Retell AI
Wu studied at the University of Southern California and, by Y Combinator’s account, “founded two investor-backed startups in college, generating six-figure revenues” (Y Combinator). He then spent about three years as a product manager at ByteDance and TikTok.
Retell started as something else. “We were actually initially building a live streaming dubbing software,” Wu has said, to help foreign streamers reach English-speaking audiences, but “that product had seven seconds of latency” and little traction (Retell AI). Customers kept asking why the voice couldn’t be generated by AI, and during Y Combinator the team concluded the translation market “was too small” (ArtU News). They launched a voice API for AI phone calls in early 2024 and built it into a full platform for call centers.
Under Wu, Retell has stayed small and lean: it raised one $4.6 million seed round, reached $100 million in run rate with about 50 people, and says it has been profitable since late 2025.

Neither Forbes nor Bloomberg has published an estimate of Wu’s net worth, and his age hasn’t been reported. Retell is private and hasn’t disclosed his stake.
In his own words
“$100 million is a big milestone for us, but our larger vision is to reimagine the contact center from first principles.”
— Bing Wu, November 2026 (Retell AI)
“If we improve the reliability of our agents, we could already replace 60, 70, even 80 percent of such offshore BPOs.”
— Bing Wu, March 2025
“I speak with enterprise executives daily, and most have AI FOMO.”
— Bing Wu, October 2025 (DestinationCRM)
“Nearly every pilot we do converts into a production deployment.”
— Bing Wu, April 2026
