All Case Studies

"One of the best real value generating SaaS GenAI products out there"
Andreas
CTO at Allright

"Voice AI that truly changes our daily sales activities: Thanks to this great support, my team can focus much more on the truly relevant conversations and is significantly relieved in day-to-day business."
Burhan
Head of Sales at McMakler

"Impressive call quality. Some of our clients were sure all the way through to the end of the call that they weren't speaking with an AI at all, despite us clearly stating multiple times before and during the conversation that they were interacting with an AI."
Marc Vincent
Head of Venture Development

"We’ve been using telli for three months to book appointments with leads, and the results have been great. It’s surprisingly easy to use, and the AI agent consistently books appointments at the same rate or better than our internal call center."
Tommaso Piatti
