Sassy doesn't just answer questions — it knows, builds, and operates.
KNOWS
Upload your price lists, contracts, staff files. Sassy reads everything and knows your business — clients, history, preferences — better than anyone on your team.
BUILDS
Need a loyalty scheme? A deposit system? A client intake form? Describe it. Sassy writes the code, deploys it, and it's live — the same day. No developer needed.
OPERATES
Sassy monitors your business 24/7, sends reminders, chases no-shows, re-engages lapsed clients, and acts — like a COO who never sleeps.
Live in 10 minutes
No IT team. No training. No migration required.
Sign up
Email, password, business name. That's it. Or connect your existing Fresha / Timely account.
Tell Sassy about your business
Price list, service menu, team roster — or let Sassy pull it from your existing system.
Connect what you have
Fresha, Timely, Phorest, Stripe, Xero — all optional. Sassy works with whatever you already use.
Say "Hey Sassy"
Start giving orders. Your AI COO is ready.
Everything your business needs. Built in.
While your competitors spend hours on admin, Sassy handles it automatically.
AI Voice Receptionist
Ara (powered by Grok Voice + xAI) answers every call 24/7 over a live WebSocket. Books appointments, handles FAQs, takes messages. Jeff pre-computes full client context in 340ms before the call even connects.
AI Intelligence COO
Claude Sonnet 4.6 is the brain. 14 cognitive engines underneath: 3-model consensus on every high-stakes answer, self-evaluation on every response, and Jeff AGSI (our autonomous AI engineer — monitors your system at 3am, fixes issues before you wake up) running in the background.
Automated Payroll
Commission, hourly, PAYE — Sassy pulls your team's hours from bookings, calculates it all, flags anomalies, and has a draft ready every Friday.
Social Media AI
Describe what you want. Sassy writes the Instagram caption, Facebook post, TikTok hook — with hashtags, correct platform length, your tone. One click to schedule.
Review Management
See every review from Google, Facebook and internal — in one place. Ask Sassy to draft a reply. Track your average rating and what clients say most.
Appointment Reminders
Automatic email reminders 24 hours and 2 hours before every appointment. No-show rate drops within days of switching on.
Build Any Feature
Need a loyalty scheme? A deposit system? A custom booking widget? Describe it in plain English. Sassy writes the code, deploys it, and it's live the same day.
GDPR & Compliance
Handle client data requests, erasure requests, consent logs, and retention policies — all from a single prompt. Stay compliant without a legal team.
14 cognitive engines. Nobody else in the market has this.
Fresha is a booking system. Moneypenny answers calls. OpenSassy runs a purpose-built AI cognitive architecture — the same class of technology used in AGSI research — behind a salon booking page.

Custom algorithms underneath:
Sassy — The Face
Talks to business owners. Answers calls as Ara. Handles the dashboard, bookings, reminders, social posts, payroll. Everything the owner sees and touches.
Jeff AGSI — The Engine
Monitors at 3am. Pre-computes call context in 340ms. Fixes production bugs and deploys. Sends daily briefings. Scores leads. Watches revenue. Neither works at full power without the other.
Every other tool is locked to one sector.
The UK market is fragmented by vertical. If you're a salon you use Fresha. If you're a clinic you use Cliniko. If you're a gym you use Mindbody. None of them talk to each other — and none of them have AI.

What this looks like in practice
Illustrative examples across different business types. Based on early product testing and representative industry benchmarks.
“We were losing 4–6 appointments every Saturday to no-shows — around £500 a weekend just vanishing. Sassy automated deposits and reminders. No-shows dropped from 18% to under 3% in six weeks.”
Sarah K.
Owner, Curl & Crown Hair Studio · Illustrative
London
“I was spending every Sunday doing rota, payroll, and chasing invoices. Six hours every week. I asked Sassy to take it over. Now it's done automatically every Friday. I use those hours to actually grow.”
Marcus O.
Owner, Kings & Queens Barbershop · Illustrative
Manchester
“I already use Fresha. I just added the AI layer on top. Sassy now handles all my client follow-ups, no-show chasing, and my Instagram posts. I didn't have to move a single booking.”
Priya S.
Owner, Glow Beauty & Lashes · Illustrative
Birmingham
“We're a small law firm — 4 solicitors. Admin was eating 2 days a week. Sassy handles client intake, appointment reminders, invoice chasing, and our compliance log. None of us touch it anymore.”
Daniel F.
Partner, Finch & Associates Solicitors · Illustrative
Bristol
“We run a personal training gym. Sassy answers enquiry calls at night, books trials, chases no-shows, and posts our transformation results on Instagram. Our PT team just trains people now.”
Chris B.
Owner, Apex Performance Gym · Illustrative
Leeds
“We needed a loyalty points system. I described it to Sassy, it built it, tested it, and deployed it the same afternoon. My developer quoted £3,200 and six weeks.”
