Most agencies build you a website. We build the operating system your business runs on — and we keep it running.
One owned engine that replaces your SaaS stack — booking, payments, invoicing, reminders, and AI — configured, hosted, and kept running for you. In Arabic, English and Russian.

The Before
The stack you're duct-taping together
✕Your booking app double-books a slot you promised on WhatsApp.
✕Three unpaid invoices you keep meaning to chase.
✕A reminder never went out — tomorrow's 10am might no-show.
✕Session notes in one app, payments in another, the client's history in your head.
✕A login for every tool. Nothing talks to anything.
The tools aren't the business — they're the tax on it.
The Architecture
We didn't digitize your chaos. We engineered it away.
Three layers. One your client feels, one you control, one that guards it all.
01
The Front Door
What your client feels — effortless, because the engineering is heavy.
▸12-phase booking flow — requests reach you, confirmed on rules you set
▸AI intake → the right service is already suggested
▸"Who is this for?" — booker ≠ attendee, handled once
▸Real openings only — Calendar free/busy + timezone + buffers
20 scheduled jobs keep the routine moving; what needs you waits on your phone
03
The Trust Layer
Beneath everything — locked night jobs, a key per purpose, and no card numbers on the server.
▸Clients download their data or delete their customer record · approvals, reschedules and cancellations audit-logged
▸HKDF key separation · push alert on forged webhooks or 10 wrong admin passwords
▸Fail-closed cron auth · zod checks on key routes
▸Card numbers never stored · every Stripe webhook signature-checked
▸Every change scanned by gitleaks (secrets) and semgrep (code)
▸HSTS + a fresh CSP nonce on every public page
Trusted with a family-consulting practice's sensitive client notes — it can be trusted with your business
Watch it run
One booking, end to end.
A replay of what the engine does with one client across the three layers — the night shift included. Nothing to type. When the phone buzzes, tap Approve, or let the replay do it.

Just need the front of house?
The AI Receptionist is a separate product that meets your customers before the OS does: it answers WhatsApp and Instagram in Arabic, English and Russian and gets the client booked. $290 a month, setup included — live on WhatsApp within 3 working days. Taken with the OS, the two prices simply add up.
New-business pricing · 5 places a month · your stage confirmed on the call
Not ready to commit? Ask for a 5-day rehearsal of an AI receptionist answering in your business's name — built before you pay, deleted if you say no. The rehearsal is free.
