Marr Labs

AI-voice agents that are indistinguishable from humans.

Marr Labs is making AI-voice agents that are indistinguishable from humans. Han and Dave previously created speech tech company Vlingo that powered the first Siri app and was acquired for $225M. Now they are taking voice to the next level by making AI-voice agents that can handle virtually any phone-based job, from answering calls to schedule appointments to call center sales and support jobs—all at a fraction of the cost of a human agent. In the US alone, businesses handle 17 billion calls a year at an average cost of $5 per call–an $85 billion addressable market.

Company Launches

At Marr Labs we are building task-specific AI-voice agents for roles like scheduling, sales, customer service, and more.

The first product is the Vox Scheduling Agent targeted at the Home Services Industry where every lost call is a lost revenue opportunity. For contractors, plumbers, electricians, and other service providers, voicemails and phone tag not only frustrate customers but also lead to lost business. Take a listen to a live Vox call.

This is our second time building a company together. We first met over a decade ago and partnered to create Vlingo, the speech tech company that powered Siri and created Samsung's Siri competitor, S-Voice before being acquired for $225M. Now, with the development of LLMs, we are creating an entirely new platform that can take original voice agents like Siri from robotic to human, which will be a game changer.
