О компании
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 to $80M ARR with a team of 50 people, up from $5M at the start of 2025.
