telli

telli is an AI voice agent platform for inbound and outbound customer calls. Agents built in its no-code Studio can qualify leads, book appointments, handle first-level support and collect payments, working in more than 20 languages and connecting to CRMs, calendars and post-call workflows.

telli is a voice AI platform for companies whose business runs on the phone. It deploys AI agents that answer inbound calls, identify what the caller wants, and either resolve the request or route it to the right person. On the outbound side, the same agents place calls at scale for lead qualification, appointment setting, upselling, reactivation, payment follow-up and satisfaction surveys. The company positions the product as an agent platform rather than a simple answering service, with the emphasis on agents that complete work during and after the conversation. The build layer is telli Studio, a no-code agent builder where conversations are shaped in natural language instead of dialogue trees. Agents draw on an uploaded knowledge base of documents and FAQs and can take real-time actions mid-call, such as booking into a calendar, collecting structured data or triggering a warm transfer to a human. Post-call workflows connect outcomes to the systems a team already uses, and every call produces a summary, sentiment reading and structured data fields. A built-in assistant named Charlie helps teams draft agents, adjust workflows and analyze call results. The platform is model agnostic, combining providers such as OpenAI, Google Gemini, ElevenLabs and Cartesia, and agents operate in more than 20 languages with local accents. Voice cloning keeps the agent on brand, smart dialing adjusts call timing and retries, and parallel calling lets volume climb from single calls to thousands without staffing changes. Quality is handled through evaluations and QA flags, live monitoring and full recordings with transcripts. It is aimed at sales, operations and customer service teams at consumer-facing companies: real estate, energy, recruitment and similar operations with high call volumes. Published case studies describe appointment lifts, automated screening calls and expanded calling capacity. telli competes with general voice agent builders and traditional call center software, and its differentiators are the operational feature depth and a compliance posture that includes GDPR, HIPAA, SOC 2 and EU AI Act alignment with EU hosting.
