About telli

AI phone agents that convert

telli is building AI voice agents that convert leads into sales opportunities for B2C companies. For example, a leading home-buying platform is using telli to fully automate their pre-qualification. We are serving customers in energy, real estate, medical products, and home services. You might think that these B2C companies want to do more self-serve and less outreach. But the truth is outbound calls are what really drive conversion. Historically, managing these calls has been complex and expensive—costing companies hundreds of thousands of dollars. With telli, for the first time, B2C companies can automate the role of a pre-sales agent, end to end.
