We're building the platform for creating consumer-facing AI voice agents.

Phone calls have long had a bad reputation. All of us have been stuck in long waiting queues, dealt with unhelpful support agents, or listened to endless hold music. Even though voice is the most natural way to communicate, it has never scaled for businesses.

We believe that every B2C company in the world - from energy providers, to telecoms, to insurances - will have AI voice agents that interact with their customers. The number of business-to-consumer conversations over the phone is going to explode in the coming years. As LLMs get better and better it will become an absolute no-brainer to use voice agents to provide consumers with a great experience.

The opportunity is massive and we know we can win.
