Zypflow — Revenue OS

A self-hosted customer engine for service businesses. Single-tenant, owned by the client, no monthly platform fees.

Zypflow is the in-house build that drives the studio's perspective on service-business automation. It's a self-hosted customer engine — enquiry to booking to follow-up — designed to run with no recurring platform fees and stay there at scale.

The problem we are building against

Service businesses lose somewhere between 30% and 40% of leads to silence — gaps after hours, unanswered DMs, missed call-backs. The standard fix is enterprise CRM at hundreds per month. For most independent operators, that math does not work.

We wanted to ship something a single-operator service business could actually run. Not lite SaaS — a full customer engine, single-tenant, owned by the client, with no surprise bills.

How it works for the customer

An enquiry comes in — WhatsApp, SMS, email, web form, missed call. The concierge picks it up, asks the qualifying questions the business actually wants asked, and offers booking slots.

If the customer books, the booking lands in the tool the business already uses. If they don't, the system follows up at intervals the business sets. Reviews are requested at the right moment. Repeat bookings are nudged. None of it requires the owner to be on their phone.

The economics only work because the system is single-tenant and owned by the client — no monthly platform fees, no usage tax that scales painfully.

Where we are

Zypflow is in active build. Real numbers and a proper outcome write-up land here when there is something honest to publish — not a marketing case study with invented metrics.
