What Slang does
Slang AI (legally Gablex Inc.) is a New York-based voice AI platform purpose-built for the restaurant hospitality industry. Founded in 2021 by Alex Sambvani (CEO) and Gabriel Duncan (CTO), the company developed an AI "superhost" that answers inbound restaurant phone calls 24/7, handling reservation booking, modifications, cancellations, FAQs, private dining inquiries, and after-hours guest communication with what the company reports as a 96%+ guest satisfaction rate. The platform's technical foundation draws on conversational AI expertise with origins among former Spotify engineers, combining speech and audio processing with natural language understanding and autonomous-agent orchestration. A proprietary dataset accumulated from 25 million guest calls across 10 million unique guests powers domain-specific model tuning, and direct CSAT measurement on every call is positioned as a differentiator versus generic voice AI offerings.
The platform serves over 2,000 restaurant locations spanning SMB independents (Sip & Guzzle, Red Rocks Café, Burgatory) through mid-market groups (Genuine Hospitality, Fireman Hospitality, Bluegrass Hospitality, DineAmic, Yes Parade, Cul+ure Collective) to enterprise multi-location operators (Texas de Brazil, Merchants Hospitality, Titan Hospitality). Official integrations with OpenTable, SevenRooms, Tripleseat, and Yelp embed Slang into the operator's existing reservation stack, and a March 2026 partnership with Fishbowl extended the platform into CRM-data-driven personalized phone interactions via the "Slang Voice" product. Reported operator outcomes include up to 50% more phone covers, 200+ hours saved per location monthly, and up to 20x ROI.
Slang AI employs a tiered subscription revenue model: Core at $380/month (up to 1,000 calls), Premium at $540/month (advanced voices and topic alerts), and Custom (quote-based, white-glove) for multi-location operators, supplemented by professional services for implementation beyond standard hours. The GTM is dual-motion: enterprise field sales for large restaurant groups alongside product-led growth with a free trial and 30-minute self-serve setup for smaller operators. By February 2026 the company had raised $68M total across a $20M Series A (June 2023, Homebrew-led) and a $36M Series B (February 2026, USVP-led), with the Series B proceeds earmarked for AI capability deepening, multi-modal experiences, and GTM team expansion.

Slang competitors and assessment
Company assessmentDirect peers
- Presto Automation: Presto is one of the most direct competitors to Slang AI, providing voice AI ordering and phone automation for restaurants, including drive-thru and pickup workflows. Both companies target the same restaurant voice AI use case with speech-powered ordering and guest interactions.
- SoundHound for Restaurants: SoundHound provides voice AI solutions for restaurants including phone ordering, drive-thru, and kiosk interactions. It is directly comparable to Slang AI in target vertical (restaurants), product category (voice AI), and customer base (multi-location hospitality operators).
- ConverseNow: ConverseNow offers AI voice ordering for restaurants focused on phone and drive-thru order taking. It competes in the same hospitality voice AI category as Slang AI, particularly for quick-service and full-service restaurant phone automation.
- OpenCity: OpenCity is a voice AI platform for restaurants handling phone orders and reservations, very similar in scope to Slang AI. Both target hospitality operators with AI-powered phone automation and integrations with ordering ecosystems.
- Hostie AI: Hostie AI provides an AI phone answering solution explicitly built for restaurants, handling reservations and guest inquiries. It is a direct competitor to Slang AI's AI Superhost, with overlapping use cases and target customers.
Emerging players
- PolyAI: PolyAI builds enterprise conversational voice agents for customer service across hospitality, healthcare, and retail. While broader than Slang, it overlaps in voice AI phone automation for restaurants and represents direct competition in conversational AI deployments.
- Voiceflow: Voiceflow is a conversational AI platform enabling teams to design, prototype, and deploy voice and chat agents. It is comparable in conversational AI technology stack but serves a broader builder audience rather than competing directly in the restaurant vertical.
- Goodcall: Goodcall provides AI-powered phone answering for small businesses including restaurants. It overlaps with Slang on voice AI for SMB hospitality but is broader across verticals and less specialized for restaurant reservation flows.
Broad incumbents
- Toast: Toast is a leading restaurant technology platform providing POS, payments, and operations software to restaurants. It is a broad incumbent that could integrate voice AI features natively, competing with Slang for budget allocation by restaurant operators.
- OpenTable: OpenTable is both a major integration partner for Slang AI and a potential competitor as the dominant restaurant reservation platform. It could conceivably launch competing voice AI features, representing an adjacent incumbent in the reservation ecosystem.
