Founding Growth Marketer

About the company

telli is creating a platform that helps businesses build consumer-facing AI voice agents. The company believes phone-based customer conversations are set to grow sharply as AI improves, and that voice agents will become a standard part of how B2C brands serve customers across sectors such as energy, telecom, and insurance.

The team sees a major market opportunity in replacing frustrating phone support experiences with natural, scalable conversations powered by AI.
