AI Operations Intern

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.

This is the perfect role for someone early in their career (e.g. recent grad) who wants to get deep exposure to how startups operate, work directly with customers, and help scale AI products in the real world.

AI is transforming how companies run their customer communication. As a AI Operations Intern, you’ll work closely with the founders and our customers to make sure everything runs smoothly. You’ll help onboard new customers, support and expand existing ones, and improve the internal processes that make telli scale.
