Founded in 2019, Slang AI has built a custom-trained, agentic voice platform that handles inbound guest calls, books reservations, routes high-value requests and recognizes returning guests, allowing hospitality staff to focus on in-person service. The system operates 24/7 and integrates with tools such as OpenTable, SevenRooms, Tripleseat and Yelp. Slang AI claims a dataset of 25 million calls from 10 million unique guests across more than 2,000 restaurant locations, enabling 95%+ guest satisfaction, a 2× lift in phone reservations and up to 20× ROI for operators. The company has raised $68 million in funding to date and reports a sustainable competitive advantage through its proprietary data moat. Future product plans include deeper AI capabilities, multi-modal experiences, personalized recommendations, post-visit follow-ups and expanded analytics for operators. The new capital will also support scaling of engineering, product and go-to-market teams as demand surges.
