"Within the first week we'd booked three jobs that used to go to voicemail. By month two it had paid for itself twice over. Honestly wish we'd done this a year ago."
Friendly AI agents that answer, qualify & book — 24/7.
We build tailor-made voice and chat agents for UK service businesses. Phone calls, WhatsApp, Instagram DMs, website chat — all handled by the same brain. Built one-to-one. Never off-the-shelf.
The building blocks.
Voice agent
Answers your phone 24/7 in a warm, natural voice. Qualifies the job, books straight into the diary.
Multi-channel chat
WhatsApp Business, Instagram DMs, Messenger, website widget. One brain across every channel.
Calendar booking
Books straight into Google Calendar, Cal.com, or your existing tool. Respects buffers and busy time.
CRM wiring
Lead summaries push to HubSpot, Pipedrive, ServiceM8 — or whatever you already use. No data falls between the cracks.
Live escalation
If a customer needs you specifically, the agent escalates in 60 seconds — SMS to your phone with full context.
Tone control
Trained on your business — your services, your patter, your house style. We tune it with you, not for you.
UK-first
Postcode logic, UK number handling, GMT scheduling, £ pricing, regional accents on voice. Built for here.
Direct support
When something needs tweaking, you message Adam directly. No tickets, no offshored support queue.
"A chatbot" isn't what you actually want.
Off-the-shelf bots are built for nobody in particular. Ona AI agents are built for one business — yours.
The bit you can't fake.
Real owners, real outcomes. (Names and businesses below are placeholders — real testimonials going in shortly.)
"Adam actually listened. Built us something that sounds like our front-of-house, not a robot. Members can't tell — and we get the lead summaries while we're still on the gym floor."
"We had a chatbot before. It was rubbish. Ona AI is in a different league — it qualifies properly, books straight in, and when something needs tweaking I just text Adam."
Same DNA. Different jobs.

Maya — AI Agent
"Hi, you've reached Sparky & Sons Electrical. I can book a quote in for you, check if you're in our area, or get an emergency callout sorted. What can I help with?"
Four steps from first chat to live.
Free 5-min Loom
We show you where leads are leaking and exactly what we'd build to plug it.
Map & approve
We map your qualifying logic, tone and escalation rules. You approve before a line of code.

Go live + support
Direct line to Adam for tweaks. Monthly check-ins. No ticket queues.


It's just us — Adam & John.
Ona AI is two co-founders on purpose. Adam handles every build and the day-to-day with clients; John co-founded it with him and is in the trenches alongside. No offshored ticket queue, no account managers you'll never speak to again. If something breaks at 9pm on a Sunday, you're texting Adam — not a help desk.
