telli
AI voice agents that run customer service calls for B2C companies in Europe.
On the record
Checkpoint: 24 months after the $15M seed close, to see if telli went deep in home-energy or spread thin globally
The call
telli runs real call volume for named German B2C brands but sits between richer AI-native rivals and contact-center sellers adding their own agents.
Telli helps businesses handle customer calls using AI instead of human agents, competing in a busy market where giants like Genesys and Five9 are now building their own AI systems. The company doesn't own its own voice technology (it rents from places like ElevenLabs) and doesn't have its own AI brain, which means competitors can copy what it does or ElevenLabs could build competing products themselves. Telli could survive by focusing deeply on one industry like home energy or insurance in Europe, where it could become the go-to choice, but reports suggest it is instead trying to expand globally against richer companies like Parloa and Sierra that are already much bigger.
Why
01
AI pressure: ElevenLabs (the voice engine telli builds on). ElevenLabs owns the voice layer telli depends on and could add its own agent orchestration, cutting telli out. Could AI do the core job? Yes, likely.
02
Bigger players: Genesys and Five9. Genesys and Five9 already sell contact-center software to telli's targets and are now bundling their own AI agents into it. Could a giant copy it? Probably.
03
What protects it. telli's agents already handle millions of live calls for named clients like Sky and Enpal, work that's costly to rip out mid-contract.
What would change this call
Genesys or Five9 announces a native AI-agent deployment inside Sky, Enpal, Vaillant, or Viessmann. Would show incumbents converting telli's own named accounts to in-house AI tools.
Parloa or Decagon announces a new German home-energy or insurance customer within 12 months. Would show better-funded AI-native rivals taking the vertical niche telli needs to defend.
telli's post-seed hiring or product news shows spend on global markets rather than German home-energy/insurance depth. Would confirm horizontal expansion over the niche path analysts see as defensible.

Key numbers
- $15M seed led by redalpine
- >$2M ARR claimed
- ~20-person team
Named risks
- No proprietary foundation model; depends on third-party voice infra (ElevenLabs-class) subject to commoditization.
- Sub-scale on revenue and capital (~$2M ARR, $18.5M raised) versus unicorn-valued peers Parloa, Decagon, Sierra.
- Incumbents Genesys and Five9 shipping native in-house AI agents, eroding telli's structural entry bar.
- Sector-wide caution: Gartner expects over 40% of agentic-AI projects scrapped by 2027.
- Strategic risk of horizontal global expansion diluting focus versus defensible vertical niche (home-energy/insurance).

Questions people ask
- Is telli profitable in 2026?
- No profitability figures are disclosed. telli reported over $2M in annualized revenue as of September 2025 (vendor-claimed) and closed a $15M seed round on July 23, 2026, suggesting it is still in growth-funded, pre-profit mode.
- Who owns telli, and is it private?
- telli is privately held and venture-backed, founded 2024 by Finn zur Muhlen, Philipp Baumanns, and Seb Hapte-Selassie. Investors include Cherry Ventures, Y Combinator, and redalpine, which led its $15M seed round announced July 23, 2026.
- Who is telli's biggest competitor?
- telli's CEO named Genesys and Five9 as the 'bigger threat' since they are shipping in-house AI agents, per a July 22, 2026 Tech Funding News interview. Better-funded AI-native peers Parloa ($3B), Decagon ($4.5B), and Sierra ($10B) also compete directly.
- Could AI replace telli itself?
- Possibly: telli does not build its own foundation voice models, instead orchestrating third-party infrastructure like ElevenLabs (valued at $11B as of July 2026). If that layer commoditizes or bypasses orchestration, telli's differentiation narrows to integration lock-in alone.
- How much funding has telli raised total?
- telli has raised over $18.5M (about EUR 16.1M) to date as of July 23, 2026, combining a $3.6M pre-seed (April 2025) led by Cherry Ventures and YC, and a $15M seed led by redalpine.
- What is telli's revenue (ARR)?
- telli reported 6-figure ARR in May 2025 and over $2M in annualized revenue by September 2025, with a stated internal target of 10x revenue growth over the following year (vendor-claimed, unaudited).
