Problem

Telli addresses the operational burden of customer-facing work for B2C companies. Businesses increasingly need to communicate across phone, chat, SMS, WhatsApp, and email, but conventional call centers, CRMs, ticket queues, dashboards, and manual follow-up do not scale cleanly. The resulting pain is missed calls, slow response times, limited calling capacity, repetitive staff work, and high operating costs. Telli claims its AI phone calls can increase engagement threefold while reducing costs by 70%.

The clearest use case is speed-to-lead and appointment conversion. Telli can call a new inbound lead within seconds, qualify budget, timing, authority, and need in a natural conversation, then book the right sales meeting or route the lead to a human. Its AI receptionist addresses the parallel inbound problem by answering every call around the clock, booking appointments, and preventing prospects from being lost to voicemail.

Product / Service

Telli is a SaaS platform for building and operating AI agents across customer-facing channels, with voice at its center. Its Charlie AI coworker helps teams set up agents, connect business systems, analyze conversations, identify issues, run experiments, and improve performance. The platform includes a no-code agent builder, multilingual and customizable voices, knowledge bases, CRM integrations, real-time actions, call monitoring, analytics, testing, and A/B comparison. Agents can handle everything from lead qualification and follow-up to support and appointment scheduling.

The delivery model is automated, always-on customer operations rather than a replacement for every human interaction. Agents can scale from one to thousands of parallel calls, perform work in connected systems, and warm-transfer exceptions to employees with conversation context and structured outcomes. This gives B2C teams 24/7 coverage and more capacity without proportional headcount, while allowing human staff to focus on complex or high-value conversations.

Market

Telli competes in the AI voice-agent, conversational AI, call-center automation, and broader AI-powered customer-communications markets. The wider voice-agent platform set includes Retell AI, Synthflow, Bland, Vapi, and Play AI; Telli’s positioning is differentiated by focusing on sales-driven B2C companies and an end-to-end operational layer rather than only providing developer infrastructure or an underlying speech model. Its target verticals include energy, real estate, home services, healthcare and medical products, insurance, and other businesses with high-volume customer calls.

Telli is not pre-revenue based on the available evidence: earlier reporting cited more than 50% monthly revenue growth for three consecutive months, although the company has not disclosed an absolute revenue figure here. The company says its agents now handle millions of conversations for hundreds of B2C companies, including Sky, Viessmann, Enpal, and Vaillant, and its customer materials cite additional deployments at Bark, Homeday, and others. Founded in 2024 and launched in late 2024, Telli raised a $15 million seed round led by redalpine in July 2026, bringing reported total funding to $18.5 million.
