Slang AI is a voice AI platform purpose-built for restaurants and hospitality, designed to answer inbound phone calls and manage reservations and guest inquiries around the clock. Founded in 2019 by Alex Sambvani and Gabe Duncan, both former Spotify data scientists, it positions itself as a leading AI digital phone agent for the hospitality industry.
The platform answers every inbound call, instantly responds to common guest questions and automatically books, modifies and manages reservations 24/7. It includes capabilities such as suggesting nearby openings within a restaurant group when one location is full, custom call routing that sends VIPs to staff or concierge lines, and real-time alerts for high-priority topics like private dining, complaints or lost items. Its conversational AI is trained on large volumes of call transcripts, and it integrates with major hospitality systems including OpenTable, SevenRooms, Tripleseat and Yelp, with setup taking roughly half an hour.
Slang AI raised a 20 million dollar Series A led by Homebrew, with restaurateur Tom Colicchio among its backers, and a 36 million dollar Series B led by US Venture Partners, bringing total funding to about 68 million dollars. It reports more than 200 customers, including groups such as Slutty Vegan, PLANTA and STUDS, and cites outcomes like 50 percent more phone reservations, up to 200 staff hours saved monthly and high guest satisfaction. It serves restaurants and hospitality operators looking to capture missed calls and reduce phone workload.
