The best tools, by merging the best techniques of every trade. Deterministic automation, no AI, so your data stays yours. And a product that grows with your feedback, and reinvests in your island.
First, one thing we do
differently from everyone.
Automation,without the AI.
Your reminders, follow-ups, schedules and payments run on deterministic rules, not a black box learning from your customers. Nothing your customers trust you with goes off to train a model.
Rule-based automation does exactly what you set, every time. No random output, no surprises.
Your customers’ data is never shipped to a third-party AI service. We sell anonymized insight, never the person.
No heavy compute, no latency. Each OS is a single-file PWA, that works even on a weak connection.
We studied the tools pros already use —
kept what works, dropped the friction.
And for every trade, its own OS.
All our OSes are here. Click any of them, or let scrolling move through them. Nine already run as real, interactive demos, the rest are in the catalog with demos rolling out.
Ten more OSes are in the catalog — FleetOS, TaxiOS, PropertyOS, YachtOS and more. Beta testers get onboarded first, before the public demo.
And that’s just a few
of nineteen, and growing.
And the best part:
it grows with you.
Premium users request features. The good ones ship to every Premium user, not just one. The product evolves with the community that pays for it, not a roadmap three time zones away.
And you’re never locked in. Leave whenever you want, your data leaves with you. No lock-in, no hostage.
of every commission we collect goes back to local projects, voted by islanders.
The tool doesn’t just grow with you, it reinvests in the environment it runs in. When your island gains, the loop tightens, and everyone in it grows.
And all of it,
at an honest price.
No subscription, no hidden fees, and you can fill your own calendar without ever paying a cent. No lock-in: leave whenever, your data leaves with you.
One tool per trade.
One ecosystem.
Every tool is wired to the same center: the app that brings you customers, and the other trades on the island.
All built on the same backbone, all wired to the same app, all synced desktop and mobile.
Saint-Martin first, Saint-Barth and Anguilla next. Your skills and reputation travel with you.
Not software rented from a faraway company. A real company on the ground, reinvesting in your island.
The beta opens September 1.
Take your seat.
Tell us who you are and which OS fits your trade. We set you up, walk you through it, and your feedback decides what gets built next. No card, no subscription — the OS is free.
A confirmation is on its way to your inbox. We’ll write the moment your OS is ready to test — and your feedback will steer what we build next.
The best tools, built for here, that grow with you and reinvest in your island. One platform to manage, promote and run your business.
