Every 10 minutes, 18 million conversations happen between businesses and consumers around the world.
For decades, the consumer side of those conversations sucked: long queues, robotic menus, repeated explanations, and advice that is often unhelpful. Most people today still cannot simply say what their problem is in natural language when communicating with businesses.
AI changes that. For the first time, companies can have natural conversations with customers at massive scale. Every B2C company - from energy providers to telcos to insurers - will use AI agents to talk to their customers. The number of conversations businesses will handle is going to explode in the coming years.
At telli, we are solving the challenges that come with that shift. Today, leading B2C companies like Sky are already using telli to deploy thousands of voice agents to provide their customers with a new experience. But building a first voice agent is easy, getting it to drive real outcomes for customers and businesses is the hard part. telli helps companies build, deploy, and improve consumer-facing AI voice agents at scale. This will become one of the most important software categories of the next decade, and we intend to win it.
We are a small, AI-pilled team that likes to solve hard problems. Be it engineering, product, or GTM - we build, experiment, and move fast, while heavily leveraging the capabilities of AI models. All of us like to challenge ourselves and take real ownership over what we do, all while still staying humble and keeping a low-ego culture.

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.
As a Success Strategist Intern, you'll work closely with the founders across both onboarding/agent development and customer success, supporting our team in making customers successful with telli.
You'll help onboard new customers, develop AI agents, support existing accounts, and build the processes that help us scale.
