Retell, the AI voice agent platform for contact centers, today launched Tell-1, a language model built specifically for live contact center calls that optimize for the high intelligence, low costs, and low latency needed. Trained on hundreds of millions of calls, Tell-1 is designed for the moments where AI voice agents most often fail: when a caller gives half an answer, changes the subject mid-task, or needs the agent to look something up and act, all while someone waits on the line.

Retell, the voice AI agent platform for contact centers, today announced it has surpassed $100 million in annualized run rate less than three years after launch, growing from $10 million to $100 million in 17 months. Retell reached the milestone with just $4.6 million in total funding, placing it among the fastest-growing and most capital-efficient companies of the current AI cycle — and in the same revenue range as competitors that have raised hundreds of millions of dollars or more.
