Run your dive center
from one dashboard.
Manage bookings, students, instructors, payments, commissions, and reporting in one place. Stop running your center through spreadsheets and WhatsApp.
Sound familiar?
Managing your center
shouldn't feel like this.
You became a dive center manager to be in the water — not to be the person cross-referencing WhatsApp threads at 11pm to figure out why last month's numbers don't add up.
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.
The instructor schedule is a shared Google Sheet. Someone always edits the wrong column.
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.
You find out if last month was profitable only after spending Sunday rebuilding your numbers in Excel.
We've been there. We built the fix.
We've spent years managing dive and free diving centers — 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.

What 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.
Never lose a booking again.
Thalassa keeps a live queue of every booking that still needs sessions assigned. No more Monday morning scramble — unscheduled bookings surface automatically, so nothing falls through the cracks.
- Never forget to schedule a session — unscheduled bookings surface automatically
- Assign lead and assistant instructors per session
- Track session status: scheduled → completed → cancelled
Every diver's history in one place.
Certifications, medical notes, dive history, emergency contacts, payment records — all in one profile, visible to the right instructors. No more WhatsApp scrolling before a morning session.
- Medical notes highlighted in amber — never missed
- Every certification, dive history, and payment in one profile
- Emergency contact and experience level always visible
Every booking tracked from deposit to last session.
When you confirm a booking, Thalassa automatically creates a session ledger — tracking every session remaining under the package. No manual counting. No surprises when a student shows up expecting a session you forgot.
- Every booking tracked from deposit to last session
- Remaining sessions visible at a glance — no manual counting
- Full booking history per student, searchable in seconds
Less WhatsApp chaos, more clarity.
Your dashboard shows exactly what's happening — upcoming sessions, unscheduled bookings, and revenue at a glance. Staff profiles include qualifications, salary, and commissions calculated automatically.
- Upcoming sessions, unscheduled bookings, and revenue at a glance
- Instructor commissions calculated automatically — no spreadsheet
- Right people see the right info — role-based access built in
Know exactly where your business stands.
Revenue, profit, burn rate, and session fill rate — calculated automatically from your bookings. The break-even tracker shows how many bookings you need to cover costs. No more Sunday spreadsheets.
- Revenue, profit, and margin tracked automatically
- Break-even tracker shows exactly how many bookings you need
- Know if last month was profitable without opening a spreadsheet
The real cost of doing nothing
What one missed booking actually costs.
Every center loses revenue to disorganization. The question is how much.

This is a partnership
What we're asking for in return.
We're not just looking for beta users. We want founding partners who help shape what Thalassa becomes.
One 20-minute touchpoint per month.
A call or an async form — your choice. We want to know what's working, what's frustrating, and what you need next. That's it.
Help us shape the roadmap.
Vote on upcoming features, share your use cases, tell us what your center actually needs. Your input becomes our priorities. Founding members decide what gets built.
Your success story — when you're ready.
Once you're getting results, we'd like to write a ~300-word case study about your center. You review every word and approve before anything goes live. You're always in control.
Total time commitment: ~20 minutes per month.
Everything else is optional and on your terms.
The people behind it
We've run dive centers.
We know what breaks.
Thalassa wasn't designed in a meeting room. It was built by people who've lived the operational chaos it solves — managing real centers, with real instructors, real students, and real end-of-month headaches.

Co-founder · Engineering
Has been running his own dive center for over three years — so Thalassa gets built against real operational pressure, not assumptions.

Previously ran a dolphin conservation agency. Brings that operational experience to making sure Thalassa fits how centers actually work — not how software companies imagine they do.

Common questions.
How long does setup take?
Most centers are up and running in under a day. We help you configure your packages, courses, and staff profiles during onboarding. There's no complex migration required — you can start fresh or bring your existing data.
Can I import my existing data?
Yes. If you have student records, booking history, or course data in spreadsheets, we can help you import it. Reach out after applying and we'll walk through what's possible for your center.
Do my instructors need training to use it?
Instructors only see what they need — their schedule, their students, their sessions. The interface is focused enough that most pick it up in one walkthrough with no formal training.
What if my instructors resist switching?
Instructors don't need to log into every feature — their view is simple and focused. Most resistance disappears once they see medical alerts surfaced automatically and their schedule in one place instead of a WhatsApp thread.
What if we have poor internet at the center?
Thalassa is optimized for low-bandwidth connections. For truly offline environments, reach out — offline support is on our roadmap and founding member input shapes what gets prioritized.
What kind of support do I get?
Founding members get priority support — direct access to the team, not a ticket queue. We respond fast because your feedback shapes what gets built next.
What happens if I cancel?
You can cancel anytime — no fees, no penalties. But once you cancel, the $49/month founding rate is permanently gone. If you re-subscribe later, it'll be at the standard price.
Is there a contract or lock-in period?
None. It's month-to-month. You can cancel with one click. The only thing that disappears if you cancel is the founding rate.
Will my data be safe?
Yes. Your center's data — student profiles, medical notes, bookings — is isolated per account and never shared with other centers or third parties. Backups are automatic.
What exactly is a "success story"?
Once you're seeing real results, we'd write a ~300-word case study about your center's experience with Thalassa. You review every word before anything goes live — you have full approval rights. Nothing gets published without your sign-off.
When does the founding price start?
From your first payment. You'll be on $49/month from day one, and that rate is yours for as long as you stay subscribed.
What if Thalassa doesn't fit my center's needs?
Cancel with no penalty. Our goal is to build something that works for your center. If it's not there yet, your feedback during the founding period is exactly how we get there.
