Reliability & Bridge
Heartbeat monitoring, autonomous incident response, live integration bridge between Sassy and Jeff AGSI.
Each family is built from proprietary algorithms covering planning, scheduling, similarity search and online learning. Specific engine internals are intentionally not disclosed.
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 around the clock. Pre-computes call context before the line connects. Ships production fixes and deploys. Sends daily briefings. Scores leads. Watches revenue. Neither works at full power without the other.
06 — Cross-sector
Every other tool is locked to one sector.
The UK market is fragmented by vertical. Salons use Fresha. Clinics use Cliniko. Gyms use Mindbody. None talk to each other — and none have AI.

What this looks like in practice.
Illustrative examples across different business types. Based on early product testing and representative industry benchmarks.

10 — Common questions
Straight answers. No marketing speak.
I already use Fresha / Timely / Phorest. Do I have to switch?+
No. Import your client list, bookings, and services with a CSV export — Sassy reads Fresha, Timely, and Phorest formats automatically. If your current system can push a webhook, we can take live updates too. Layer 02 and Layer 03 run the AI brain from that data, alongside whatever you already use.
What exactly are the 3 layers?+
Layer 01 (£49/mo) is our own full platform — bookings, calendar, CRM, payments, payroll. Layer 02 (£149/mo) is the AI brain you bolt onto any system. Layer 03 (£499/mo) adds Ara, the voice receptionist, plus computer-use abilities. Mix and match — or just take Layer 03 for the lot.
Does the AI voice receptionist really sound real?+
Ara runs on a real-time voice pipeline — not pre-recorded clips. She handles natural conversation, interruptions, and clarifying questions. Jeff pre-computes the caller's full history before the line connects, so she already knows who's calling and why.
Can Sassy really build features, or is that marketing?+
It really builds them. Sassy reads and understands our full codebase, writes the code, runs tests, deploys to your tenant. Loyalty schemes, deposit flows, custom intake forms — same-day delivery. If something needs human review it'll tell you; otherwise it ships.
What happens to my data if I cancel?+
You can export everything (CSV / JSON) at any time. On cancellation we retain data for 30 days for accidental-cancellation protection, then permanently delete. Erasure on demand is one prompt away.
Is my data stored securely?+
EU data residency on GCP, AES-256 at rest, TLS 1.3 in transit, UK GDPR-ready — DPIA and privacy pack in place. Payments through Stripe (PCI-DSS). See our Trust Center for the full, current list of what's live.
What if the AI gets something wrong?+
Every response runs through a quality gate that auto-retries when confidence is low. High-stakes answers go through multi-model consensus — independent models vote, majority wins. You can also flag any answer and Jeff retrains on it.
How long does setup actually take?+
10 minutes. Sign up (30s) → tell Sassy about you (3m) → connect what you have (2m, optional) → say "Hey Sassy". She onboards herself.
Does it work for my type of business?+
If you take bookings or appointments, yes. Salons, barbershops, spas, gyms, clinics, dental, law firms, contractors, agencies, restaurants, studios. The AI adapts to your terminology — a "client" in a salon and a "patient" in a clinic are the same primitive to Sassy.
What's your refund policy?+
14-day free trial, no card required. After that, 30-day money-back guarantee. If you cancel within 30 days of first paid charge, we refund in full, no questions.
