Growth Hacker Intern

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

Since launching last year at Y Combinator, we've grown >$2M in annualized revenue with a team of only 12 people.

Today, most B2C 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 them to outsource to poor-quality external call centers or have their internal teams spend hours on repetitive calls.

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

We've seen firsthand that legacy phone systems are not designed for an AI-first world. That is why we are building the first AI-native phone system that lets B2C companies manage both their human and AI teams on one platform.

Our founding team knows this problem inside-out, having managed a 150-person call center before. We know how painful and expensive scaling phone operations can be for companies.

There is a lot of work ahead. The opportunity is massive. We are ending an era of poor-quality external call centers.
