Telli

Telli is an AI phone platform for sales-driven B2C businesses that automates consumer-facing call operations end to end. Teams build human-like voice agents in telli Studio (no-code), connect CRMs like Salesforce and HubSpot, run smart auto-dialers with retry logic, and let agents complete real-time actions mid-call: booking appointments, prequalifying and nurturing leads, making product suggestions, collecting payments, and warm-transferring complex cases to human operators. It runs across real estate, energy, solar, HVAC, telecom, finance, insurance, and medical products in 30+ languages, handling thousands of automated calls per day. Telli deliberately switches between underlying models (OpenAI, Claude, and others) to give customers the best available option, and clones hired voice actors' voices via ElevenLabs and Cartesia for quality. Built-in compliance and security features redact personal information and help meet GDPR and HIPAA requirements, and a notable capability lets its agents navigate Apple's iOS call screening in real time, identifying themselves and continuing the call to preserve reachability. Founded by an ex-Enpal team that saw call-automation pain firsthand at the German energy unicorn, Telli raised a $3.6M pre-seed from Cherry Ventures and Y Combinator and processed close to a million calls with a six-person team at 50%+ monthly growth. Customer references report booking appointments at or above the rate of an internal call center.
