The Thalassa platform
Your dive center runs on spreadsheets.
There's a better way.
Manage bookings, students, instructors, payments, commissions, and reporting in one place. Stop running your center through spreadsheets and WhatsApp.
Managing your center
shouldn't feel like this.
You became a dive center manager to be in the water, not stuck cross-referencing WhatsApp threads at 11pm to figure out why last month's numbers don't add up.
Sound familiar?
You find out if last month was profitable only after spending Sunday rebuilding your numbers in Excel.
It's Monday morning and you have no idea which bookings from last week still don't have sessions.
Month-end payroll means two hours with a calculator, a spreadsheet, and a lot of second-guessing.
The instructor schedule is a shared Google Sheet. Someone always edits the wrong column.
A student flags asthma on their intake form. It's buried in email. You find it after the briefing.
You find out a session wasn't assigned when the student is already at the dock.
We've been there. We built the fix.
We've spent years managing dive and free diving centers and living every one of these problems. Thalassa exists because we stopped waiting for someone else to solve them. Every feature comes from real operational pain, not guesswork.
See what we builtWhat changes
Less admin. Fewer mistakes.
More confidence.
Thalassa was designed around one core flow (the way dive centers actually work), then built outward from there.
Less WhatsApp chaos, more clarity.

Know exactly where your business stands.
Revenue, profit, burn rate, and session fill rate, all calculated automatically from your bookings. The break-even tracker shows how many bookings you need to cover costs. No more Sunday spreadsheets.
