I have been a customer of Telli’s for approximately 6 months now. In that time I have seen them consistently deliver new and impressive capabilities to their platform. Their support is very good; nothing has slipped through the cracks.

For context, I am the Head of Engineering at a start up in the United States. Given the technical nature of my work, what Telli has built and provided to its customers is astounding. I have the ability to spin up a new voice AI agent on demand and refine its persona with just a few keystrokes.

The _velocity_ that I can move with for voice AI agent needs is just about perfect. I won’t say perfect because I don’t want them to take their foot off the gas! Review collected by and hosted on G2.com.

The only downside I have experienced with Telli is one they can’t do anything about for now. We operate in vastly different time zones, so when an issue arises there is a little extra wait. It’s never been a blocker, and moreover what they’ve added to the platform has mitigated many support issues. Review collected by and hosted on G2.com.

Every now and then, smaller bugs appear for which there is no direct answer. Review collected by and hosted on G2.com.

We’ve been using Telli for three months to book appointments with leads, and the results have been great. It’s surprisingly easy to use, and the AI agent consistently books appointments at the same rate or better than our internal call center. What’s especially impressive is how natural the conversations feel — people generally don’t realize or don’t care that they’re speaking with an AI. The onboarding was quick, and the whole system works well right out of the box. Review collected by and hosted on G2.com.

While the core functionality is strong, the platform’s interface could be more polished. It feels like the team is prioritizing the agent’s performance (which makes sense), but that leaves parts of the dashboard and reporting feeling a bit basic. That said, we’ve already seen improvements since we started, so it’s clearly moving in the right direction. At the start, it took a bit of fine-tuning to have the agent pausing for the right amount of time during the conversation, in order to avoid talking over customers but also not having awkward pauses.

They're continuously innovating and realising new products. They are very flexible and attentive. Easy to communicate with them. I'm very happy we are using Telli. Fairly straightforward to integrate with our systems and we were live within 1-2 weeks. Review collected by and hosted on G2.com.

Billing gets a bit complex, but they're realising a billing section soon. Review collected by and hosted on G2.com.

What I like about Telli is the team's hands-on approach with weekly feedback sessions and the very strong product! I have yet to see a product as strong as Telli's, especially on the German-speaking market. Review collected by and hosted on G2.com.

I would like to see even more insights and also have the opportunity to expand into even more countries, but the language models are not yet ready for that. Review collected by and hosted on G2.com.

The automation, the quick fixes and feature roll-out. Every request gets taken seriously and pipelined. Review collected by and hosted on G2.com.

Still lots to build and not too many features for self-service yet. Review collected by and hosted on G2.com.

The product is continuously making great progress. The team at Telli is always approachable, committed, and supports us with expertise and dedication. Review collected by and hosted on G2.com.

The only disadvantage I still see is that a real agent can respond to the customer even more individually. Review collected by and hosted on G2.com.

Customer Service, ability to adapt quickly, realistic voice, UI of dashboard Review collected by and hosted on G2.com.

Mostly the pricing, I would like to have more customization options (especially that I can implement new call variables / prompts on my own) Review collected by and hosted on G2.com.

As one of the leading players in the energy sector, we have a strong need for outbound customer communication. telli’s solution already demonstrates today what will become the standard of tomorrow. From the experience we made with telli over several months, we believe that they have the potential to fundamentally transform the pre-sales & sales process.
