Slang AI Raises $36M Series B for Voice AI
Slang AI, a voice AI platform purpose-built for full-service restaurants, has raised $36M in Series B funding. The platform answers every inbound call 24/7, handles guest inquiries, manages reservations across OpenTable, SevenRooms, Tripleseat, and Yelp, and delivers real-time analytics and alerts. This capital will fuel platform enhancements and market expansion for multi-location operators.
Voice AI Concierge Captures Revenue
The timing aligns with surging AI adoption in hospitality, highlighted by Slang's recent proprietary data report on full-service restaurants. Slang's pre-trained model, built on 17 million guest calls, tackles staffing shortages and missed reservations that plague the sector. Trusted by Texas de Brazil and Riot Hospitality, it positions Slang to scale amid operational pressures.
Staffing Shortages Drive Missed Calls
Full-service restaurants handle massive call volumes but struggle with understaffing, leading to unanswered phones and lost revenue. Slang's traction signals the scale: one client processed 15,000 calls and booked 1,500 reservations in a single month. Traditional phone services lack the nuance for natural conversations and seamless integrations, failing to deliver consistent guest experiences.
Pre-Trained AI Outperforms Legacy Systems
Slang AI's Voice AI Concierge Platform stands out with its training on over 17 million restaurant-specific calls, enabling natural, context-aware interactions. Unlike generic chatbots or manual answering services, it integrates directly with reservation systems for instant bookings and bilingual support in English and Spanish. The Analytics Dashboard provides insights, while Smart Alerts prioritize high-value inquiries, boosting phone covers by up to 50% and saving over 200 staff hours monthly.
Deployments demonstrate speed: Riot Hospitality rolled it out across 12 locations in one week. This delivers 20x ROI and 96% guest satisfaction, far surpassing competitors reliant on scripted responses.
Series B Validates Restaurant AI Momentum
The $36M Series B reflects strong investor belief in Slang's proven model amid hospitality's digital shift. With SOC 2 Type II compliance and recognition as one of Fast Company's Most Innovative Companies in Dining for 2024, the funding signals growth capital for nationwide expansion. It connects directly to Slang's strategy of capturing revenue opportunities through AI-driven efficiency.
Restaurant Tech Investments Accelerate
Hospitality operators face intensifying competition, with phone channels critical for 30%+ of reservations. Slang's recent partnerships, like with Tripleseat, enhance revenue capture by phone. Industry trends show AI addressing labor gaps, with Slang's rapid deployments underscoring market fragmentation toward specialized voice solutions.
Recent activity reinforces momentum: a landmark data report on restaurants (August 2025), next-gen unveil at National Restaurant Association Show (May 2025), and Tripleseat integration (September 2025).
