Voice AI companies selling into SMB service businesses (trades, clinics, salons)

Voice AI for SMB Service Businesses — Sourcing List

1. Avoca — AI voice agent + coaching platform for HVAC/plumbing contractors, deeply integrated with ServiceTitan. YC-backed, strong traction in home services; sells directly into trades with call-answering + CSR training, a wedge into the whole front office.
2. Sameday AI — AI phone agent that answers and books jobs for home service companies (HVAC, plumbing, pest control). Early-stage, trades-native positioning; charges per booked appointment, which aligns well with SMB buying psychology.
3. Rosie (heyrosie.com) — AI answering service purpose-built for small businesses like contractors and local services. Genuinely early, low-price self-serve motion — interesting as the "voice AI for the long tail" play rather than mid-market.
4. Goodcall — AI phone agent for local businesses (salons, restaurants, shops) that books, answers FAQs, captures leads. Founded by ex-Googlers; longer history but still relatively under the radar, with a clear SMB self-serve wedge.
5. Arini — "AI receptionist for dentists" — answers calls, schedules appointments, handles insurance questions for dental practices. YC-backed, vertical-specific with PMS integrations; dental is a classic missed-call-heavy SMB vertical.
6. Assort Health — Voice AI for medical call centers and specialty clinics (scheduling, referrals, refills). Raised early venture rounds; sits between SMB clinics and multi-site groups — good expansion dynamics from single practices upward.
7. Hello Patient — AI voice/text agent for patient scheduling and communication at healthcare practices. Early-stage (founded by a Zocdoc alum), signal being strong founder-market fit in clinic front-desk workflows.
8. Slang.ai — Voice AI answering for restaurants and location-based businesses (bookings, hours, FAQs). Seed/Series A stage; restaurant-first but expanding into adjacent SMB service categories, proven willingness-to-pay per location.
9. Numa — AI that answers and manages calls for auto dealerships and service departments. Venture-backed and vertical-focused; auto service is a high-call-volume trade with clear ROI attribution on recovered missed calls.
10. Loman.ai — 24/7 AI phone agent for restaurants and small local businesses, handling orders, reservations, and questions. Very early and lesser-known; interesting as a low-CAC, self-serve entrant.

White-space gaps noticed:

1. Outbound, not just inbound. Nearly every company here is an AI receptionist. Almost no one is doing proactive outbound voice for SMBs — recall/reactivation calls (dental recalls, HVAC maintenance renewals, salon rebooking), which is where the highest-ROI revenue sits and where humans reliably fail to follow up.
2. Salons/beauty/wellness are underserved. Trades, dental, and restaurants are crowded, but the appointment-heavy beauty/wellness segment (salons, med spas, barbershops) — millions of locations, chronic missed calls, existing scheduling rails via Boulevard/Vagaro/Mindbody — has no dominant vertical voice AI player yet.
