Devynium
For concierge companies & short-term rental managers

The operations layer for modern concierge companies.

Devynium replaces WhatsApp, Excel and manual reports with a clear, automated back-office — housekeeping, maintenance, owners, finances — connected to your existing PMS.

Your PMS confirms the booking. The real work starts after.

Most concierge companies manage bookings in professional software — and everything else in WhatsApp, Excel and team memory.

💬

Operations live in WhatsApp

Cleaning assignments, breakdowns, check-in changes: everything gets lost in group chats. Nobody knows what's confirmed, done or forgotten.

📊

Money lives in Excel

Expenses, purchases and owner balances are rebuilt by hand in spreadsheets — fragile, slow, and error-prone.

🗓️

Reports eat your evenings

Every month-end, hours of copy-paste to explain to each owner what happened with their property and their money.

Result: errors before check-ins, hours lost every week, and owners left waiting.

How it works

One flow, from booking to owner report.

Every event in your operation triggers the next step automatically — no messages to send, nothing to remember.

1

Booking

A reservation lands in your calendar.

2

Check-out

Guests leave. The status updates itself.

3

Housekeeping

A cleaning task is created and assigned — automatically.

4

Validation

The cleaner completes the checklist. The unit is check-in ready.

5

Owner report

Every task and expense flows into the monthly statement.

No message sent. No spreadsheet opened. Nothing forgotten.

The strongest module

Housekeeping that runs itself.

The riskiest moment in short-term rental is the gap between a check-out and the next check-in. Devynium closes it — automatically.

1

Tasks created from check-outs

The moment a departure is confirmed, a cleaning task exists — with the property, deadline and next arrival attached.

2

A schedule your team can trust

The cleaning planning builds itself around your calendar. Assign cleaners in one tap, rebalance in seconds.

3

Cleaner access, no training needed

Housekeepers get their own simple view: today's tasks, checklists, photos. No app store, no manual.

4

Validation before the next guest

Each task is checked and validated. You see at a glance which units are guest-ready — and which aren't.

Built in the field

Born inside a real vacation rental operation.

Devynium wasn't designed in a pitch deck. It was built inside a working property management operation in Saint-Martin — shaped by real check-outs, real cleaning teams, real maintenance surprises, and real owners waiting for their monthly report.

“Before, every check-out meant WhatsApp messages and a spreadsheet to update. Now the cleaning task is just there, validated before the next arrival — and the monthly owner report takes minutes instead of an evening.”
