Industries

How agents help
your business

Pick your industry — see exactly what AI agents do for businesses like yours.

Care homes & healthcare providers

Families call at all hours with questions about availability, visits, and care options. Your AI Receptionist answers every call professionally — and books viewings while your team is with residents.

  • Answer family enquiries 24/7 with empathy and accuracy
  • Book facility tours and callback appointments
  • Send SMS confirmations and visit reminders
  • Route urgent calls to on-call staff instantly
0 of routine enquiries handled without staff

Plumbers, electricians & local trades

You're on a job site when the phone rings — and that missed call is a lost £500+ job. AI captures every enquiry, gets the details, and books the callback before the customer calls your competitor.

  • Never miss an emergency or quote request
  • Capture address, job type, and urgency via phone or SMS
  • Send automated "we'll call you back" confirmations
  • Outbound agent follows up on quotes that went quiet
0 more leads captured vs. voicemail alone

Salons, spas & aesthetic clinics

Empty chairs and last-minute cancellations hurt revenue. AI fills your calendar by replying to Instagram DMs, confirming via WhatsApp, and sending SMS reminders that actually get read.

  • Book appointments from Instagram & Facebook DMs
  • Fill cancellation slots with waitlist outreach
  • Send SMS reminders 24h before appointments
  • Answer pricing and service questions instantly
0 reduction in no-shows with SMS reminders

  • Answer "how much" and "when can I start" 24/7
  • Website chat converts browsers into booked students
