Marr Labs builds AI voice agents designed to be indistinguishable from human callers, handling phone-based scheduling, lead qualification, and customer service for regulated industries like home services, healthcare, and mortgage. Han Shu and Dave Grannan founded the company in 2023, drawing on their earlier work building Vlingo, the speech technology that powered Siri and Samsung's S-Voice before Vlingo's $225 million acquisition; Marr Labs went through Y Combinator's Winter 2024 batch.
The company's flagship product, Vox, connects to callers in roughly 660 milliseconds, avoiding the hold-time gap that gives away most automated phone systems, and layers in document intake, workflow orchestration, and real-time compliance enforcement for conversations in banking, insurance, and healthcare settings. Vox ships in task-specific configurations, a mortgage agent, a scheduling agent for home-services calls, rather than one general-purpose voicebot, and integrates with Salesforce, HubSpot, and existing telephony systems.
Marr Labs suits mid-market and enterprise phone-support operations in regulated sectors that need call volume handled without expanding headcount. Pricing isn't published; the company sells through a custom quote, with third-party estimates suggesting deployments start in the low thousands of dollars monthly.
