Preface Ventures Backs heytruffle to Handle Restaurant Phone Calls with Voice AI

heytruffle, a startup building a managed voice AI service designed to handle incoming restaurant phone calls and recover missed revenue, has secured an undisclosed investment from Preface Ventures. The funding, announced August 3, 2026, will be used to advance the company’s voice AI offering, though specific product roadmap details were not disclosed.

The investment amount and round type remain confidential. Preface Ventures, the sole named investor, has a track record of backing early-stage technology companies, but no further terms were shared. heytruffle’s service targets a persistent operational pain point for restaurants: phone orders, reservations, and inquiries that go unanswered during peak hours, leading to lost revenue. By deploying a managed voice AI, the company aims to ensure every call is handled, capturing orders and information that might otherwise slip through.

The restaurant voice AI sector has seen increasing activity as labor shortages and rising costs push operators toward automation. Competitors in the space range from general-purpose conversational AI platforms to niche players focused on specific tasks like reservation management. heytruffle’s emphasis on a fully managed service suggests it may differentiate by handling not just the technology layer but also the ongoing tuning and oversight that restaurants often lack the resources to manage internally. Without disclosed metrics or customer names, however, the scale of its current deployment remains unclear.

The undisclosed nature of the investment leaves open questions about heytruffle’s valuation and growth trajectory. Still, Preface Ventures’ backing signals confidence in the company’s approach to a concrete problem. As restaurants continue to seek efficiency gains, voice AI that can reliably answer calls and recover revenue could become a staple tool, provided it clears the high bar for accuracy and customer experience that the hospitality industry demands.
