ABOUT RETELL AI
Retell AI is using first principles to reimagine the call center with cutting-edge voice AI.
Thousands of companies now utilize Retell’s AI voice agents to handle sales, support, and logistics calls that once required large teams of human agents. Backed by Y Combinator, Alt Capital, and other leading investors, we have scaled rapidly to tens of millions in ARR with a small, high-velocity team.
Our vision is to build a modern customer experience platform where AI agents operate as frontline workers, QA systems, and operational managers continuously executing, monitoring, and improving customer interactions.
We’re looking for builders who want to work on the hardest problems in applied AI, move fast, and have outsized ownership in shaping the company.
Let’s build the future together.
