telli was founded in 2024. We were part of the YC Fall ‘24 batch. In the last couple of months, we’ve grown to 6-figure ARR and raised a $3.6M seed from investors including Cherry Ventures, Y Combinator, and great strategic angels

about us

At telli we are building AI voice agents that are reshaping an entire industry.

Since launching 8-months ago, we raised a $3.6M pre-seed round from Cherry and Y Combinator and grew to >$1M in ARR. We are looking for a team members who want to go all-in to help us achieve the next milestone: $10M in ARR.

Two of our co-founders Finn and Philipp previously scaled the heat pump unit of energy unicorn Enpal from 0-150 people. They've seen the ins and outs of scaling phone-based customer processes. These businesses are rushing to deploy AI voice agents. However, creating a demo is easy — building reliable agents that handle millions of calls in production is incredibly hard.

In a world where intelligence becomes a commodity, it is up to us builders to craft new product experiences that let people harness the power of AI.

But building AI voice agents comes with challenges:

• What is the most intuitive way for humans to build and adjust their own AI agents?

• How do you build agents that work reliably across millions of calls in a world of non-determinism?

• How do you ensure that customers can use the latest foundational models without having to understand the technical trade-offs?

• How do you enable companies to build hybrid teams of human and AI agents?

• What does human-computer interaction look like if, instead of having UI elements, you have a hyper-intelligent sidekick?

These are unsolved problems. Problems that haven't existed since the invention of computers. Solutions that worked in a pre-LLM world won't work today. Nobody knows how to solve these problems; it's up to us to figure it out.

We’re a small, fully in-person team based in Berlin. Even though most people have told us to build this company in SF because of “better talent” - we know there is amazing talent in Europe. We believe you can build a multi-billion dollar software company in Europe, and there is no better time to do this than now.

what you’ll do:

• play a significant part in creating telli’s gtm engine to help 10x telli’s revenue over the next year

• take full ownership of key growth channels and optimize them

• discover and experiment with new growth initiatives and markets

• build and manage own relationships with customers

• drive the complete sales cycle: generating, qualifying and closing customers end-to-end (how much sales you do is for you to decide)

• be part of building out the founding growth team

• build processes with an AI automation-first approach

what makes you a great fit:

• you have experience in building or scaling companies either in a startup environment or in own projects (ideally in a growth setting)

• you have strong customer empathy and business sense to understand problems, pain points and needs of different companies

• you have experience in and enthusiastic about leading initiatives end-to-end

• you’re are hands-on and not afraid of doing unglamorous work

• you love solving problems and figuring things out on your own

• you’re a strong communicator in both English and German

• you want to work with smart and friendly people with (self-reported) low ego

• you want to work on-site 5 days a week in Berlin

you may _ not _ make a good fit if…

• you need detailed instructions and shy away from taking responsibility

• you lack experience with automation/AI tools or basic technical understanding

• you're only interested in high-level "strategic" work

• you don't enjoy direct customer interaction or thriving in dynamic environments

• you prefer working remotely

• you prefer working with minimal collaboration

• you avoid hands-on, practical work

• you want to work a 9-5 job

our tech stack includes TypeScript, React, TanStack, Node, Python, Postgres as well as Temporal.io and Pipecat. But more than familiarity with any specific technology, we value a customer-centric approach and ability to ship end-to-end features.
