What telli is

telli is an AI voice platform for businesses that want phone calls answered and placed by AI agents. It sits between a no-code agent builder and a call operations platform: operations, sales and customer service teams define what an agent should do, and the platform runs it across inbound and outbound calls. Technical teams can go further through an API. The company's site calls it "The #1 AI voice platform for agents that sell, support and operate" and says it powers "millions of customer conversations for leading B2C brands". The company behind it is telli technologies GmbH, and the site is offered in English and German.

The site announces that "telli raises $15M to build AI for customer-facing operations". It is a platform for the telephone first. Its chatbot-builders membership rests on the conversational agents themselves: telli agents hold natural spoken conversations, answer from a knowledge base and take actions, but the pages describe voice calls (with SMS confirmations) rather than a website chat widget.

What you build and how

The product follows what the homepage calls the telli Method, a loop of Build, Run, Improve and Scale. Each stage has named parts of the product behind it.

Build in telli Studio. The homepage describes Studio as an "Intuitive no-code agent builder to change and improve conversations with natural text." You change an agent by editing plain language instructions rather than wiring a flow chart or writing code, so a support lead can adjust wording without waiting for an engineer. A Knowledge Base lets you "Upload documents and FAQs so your agent answers correctly."

Build and refine with Charlie. The site introduces Charlie as an assistant inside the platform: "Tell Charlie what you want to achieve." According to the homepage, it helps you build and refine agents, automate workflows, analyze calls and continuously improve performance. In practice Charlie is the conversational layer on top of Studio: you describe a goal and let it propose changes.

Voices, languages and models. The homepage offers a voice library plus voice cloning "to stay on brand." Agents are deployed "in 20+ languages with native fluency," and a second feature card says 30+ languages with local accents and cultural context, so the homepage gives 2 counts. The platform is described as model agnostic and "never locked to one provider," which means one agent definition is not tied to a single model vendor.

Actions, workflows and integrations. Agents can take real-time actions during the call, with pre-built actions or custom ones. Post-call workflows connect telli to the systems you already use. The integrations card says "Connect Salesforce, HubSpot, and any CRM natively or via API," and a built-in contact manager stays in sync with your CRM. A comparison page on the company's own domain sums the product up as combining "voice automation with workflow management, CRM integrations, analytics, and business-ready deployment tools," with both no-code configuration and API-based customization.

Telephony and dialing. You can use telli phone numbers or bring your own through SIP trunking. Smart Dialing optimizes call timing and retries for pickup rates, and the homepage says you can scale "from 1 to thousands of parallel calls without people and infrastructure changes."

Run, review and improve. Live Monitoring gives an overview of all active calls and working agents. Analytics dashboards track conversion rates, call duration and outcomes. After each call you get pre-built and custom outcomes, "from summaries to sentiment and structured data," and Call Reviews let you listen to recordings and read full transcripts. Evaluations and QA let a reviewer "Flag calls that need attention and mark them as pass or fail to maintain quality," which feeds the Improve step.

What the agents do

The homepage groups use cases into 3 teams, and each group maps to a kind of call.

Sales. Lead qualification reaches customers, qualifies intent and books relevant sales meetings. Upselling identifies interest and turns service into sales conversations. Reactivation and win-back calls re-engage dropped or churned customers, with personalized offers in the win-back case. Appointment setting books qualified meetings directly into a team's calendar.

Operations. Appointment scheduling confirms and schedules appointments at scale "with real-time calendar availability". Reminders and follow-up handle inquiries and automated reminders. Payment collection follows up on overdue payments. Data collection gathers customer information, runs surveys and enriches CRM records.

Customer service. Proactive care triggers outbound calls to solve problems before customers churn. The IVR and receptionist use case accepts calls, identifies intents and routes them. First level support handles multi-step requests and takes system actions. Feedback and surveys collect satisfaction answers through natural conversation.

The solutions menu names the industries it targets: solar and HVAC, healthcare, real estate, insurance, recruiting, energy, financial services, consumer and telecom.

What the pages say about pricing, customers and trust

The homepage offers 3 ways in: a "test AI call" you can try yourself, a "Try for free" button in the header, and a free discovery call to book a demo. The pages publish no prices, plan names or usage limits, so costs come from a conversation with the company.

On customers, the homepage carries 2 video case studies. One is titled "How Sky scaled proactive customer engagement with telli's Voice AI in under 3 weeks". The other is "How 1KOMMA5° scaled customer engagement with telli's Voice AI". Burhan, Head of Sales at McMakler, says the product means his team "can focus much more on the truly relevant conversations." Tommaso Piatti, Director Operations, says that after 3 months "the AI agent consistently books appointments at the same rate or better than our internal call center." Another quote opens with "Impressive call quality."

On security, the site says "We safeguard data with the highest standards of security and compliance," and the footer links a Trust Center and documentation. The homepage names no certification.

Who it suits

telli fits operations, sales and customer service teams at B2C companies that make or take many routine calls: appointment confirmations, payment reminders, lead follow-up, first level support. The Studio-plus-Charlie approach suits a team that wants to own the conversation design without code, Salesforce and HubSpot users get a native connection, and the API route keeps a door open for developers. The language support matters for businesses serving several markets.

It suits a smaller team less if the goal is a quick self-serve experiment with known costs, because the pages show no prices or limits. It is also less natural for someone who wants a website chatbot or a messaging bot, since the pages describe voice calls.
