Retell AI
Supercharge Your Contact Center Operations with AI Phone Agents
About the Company
Retell is building the AI voice layer for every business.
We’re replacing outdated call centers with real-time AI voice agents that sell, support, and retain customers at scale.
Voice is still the most natural way humans communicate, yet it’s been stuck with legacy tech for decades. We’re changing that by bringing speed, empathy, and reliability to every phone conversation.
In under two years, thousands of companies now run on Retell. We’ve grown to $35M ARR, raised a $4.7M seed, and scaled a 24-person team, backed by Y Combinator, Altman Capital, and top-tier investors.
We’re now one of the top 50 AI apps in a16z’s rankings and a top-ranking startup on the Lean AI leaderboard.
We’re moving fast, tackling hard technical problems, and setting the standard for voice automation. If you want to help define the future of how businesses talk to customers, this is the place to do it.
