about us

At telli, we're building the first AI-native phone system.

Since launching last year at Y Combinator (the same investors behind Airbnb, Stripe, Twitch, Coinbase, and others), we've grown >$2M in annualized revenue with a team of only 12 people.

Today, many companies fail in their customer communication not because they don't care, but because they can't keep up. The sheer volume of calls forces to rely on low-quality outsourced call centers or have their internal teams waste hours on repetitive calls.

With telli, our customers now rely on AI voice agents that handle their repetitive calls, freeing human to focus on what matters - talking to customers when it counts. The result: higher efficiency, happier teams, and better customer experiences.

Legacy phone systems weren’t designed for an AI-first world. That is why we are building the first AI-native phone system that lets companies manage both their human and AI teams on one platform.

Our founding team knows this problem inside-out. We ran a 150-person internal call center at Enpal. We know how difficult and expensive it is to scale high-quality customer experience with phone calls.

The opportunity is massive!!! and we're just getting started. We're on a mission to let every company provide a world-class customer experience by ending the era of low-quality call centers.

Mission

You'll be telli's first marketing hire. Your job is to build and own telli’s growth marketing engine from strategy to execution.

What you'll do

  • Growth Marketing Strategy & Execution

    • own and execute telli's inbound growth engine end-to-end and set strategy across all channels (SEO, paid, content, and product marketing)

    • build repeatable marketing playbooks with an AI-automation-first approach

    • track, measure, and report on all campaigns. Set KPIs, run experiments, iterate fast, and communicate results across the org

  • Positioning & Storytelling

    • Be the person who translates what we're building into language the market understands

    • Work closely with product and founders to shape how telli shows up, on the website, in campaigns, in the press

  • Paid & Organic Acquisition

    • own paid acquisition across channels (paid social, display, programmatic)

    • research, plan, and execute SEO tactics, also with a focus on AI discoverability

    • build and manage press relationships, pitch stories, handle media, turn product milestones into coverage

  • New Channels & Experimentation

    • constantly experiment with and find new channels

What makes you a great fit

  • 1-3 years in growth or product marketing, ideally at an early-stage company where you were one of the first marketing hires or built the function from scratch

  • you're exceptionally creative and bring original ideas to messaging and campaigns, not just follow playbooks

  • you have a strong sense for positioning and storytelling, you turn technical products into narratives people remember

  • you're data driven and make decisions based on experiments and numbers, not gut feeling

  • you pick up new concepts, channels, and tools fast and always know what's working in the market

  • you use AI and automation aggressively and never do manually what can be automated

  • 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

  • (Bonus) You've built your own business, project, or side hustle before

You may not be a great fit if…

  • you only work with detailed instructions and shy away from taking responsibility

  • you lack hands on experience running marketing channels yourself

  • you're only interested in high level “strategic” work without getting into the execution

  • you prefer following best practices over coming up with original approaches

  • you prefer working with minimal collaboration

  • you prefer working remotely

  • you want to work a 9 to 5 job

Perks

  • Founding marketing role with a clear path to Marketing Lead

  • Above-market pay & equity

  • Access to any (AI) tool that makes you more productive

  • Gym subscription (Urban Sports)

  • Free dinner in the office
