The Problem

Every unfilled cancellation is revenue you never get back.

Your booking platform sends a notification when a slot opens. Your customers still have to race to claim it manually — and most lose. The slot goes empty. The revenue disappears. Slotly plugs directly into your existing calendar and closes the loop automatically.

Without Slotly

Client cancels. Slot goes empty.

Your platform sends a notification. The client is busy. Nobody books.

That hour is gone. The revenue is gone. Forever.

"Summer weekends book out weeks in advance. Notifications don't cut it — by the time I tap the link, someone grabbed it. Slotly books it for me automatically. I actually get out on the water on the days I want."

Your stylist had a cancellation. You got it.

The appointment you wanted was taken. Then it wasn't — and you probably missed it.

Slotly watches your salon's calendar 24/7. The moment a cancellation opens, it books your spot automatically — no racing, no refreshing, no luck required. You just get a confirmation.

Get the next opening

The boat you wanted just opened up.

Boat club reservations disappear fast — especially summer weekends. Refreshing the app is not a strategy.

Set your preferred boats, dates, and times once. Slotly monitors your club's availability around the clock and completes the reservation the moment a cancellation appears.

Stop missing boats

First on the tee when a spot opens.

Weekend tee times book up a week out. Cancellations happen every day and they're gone in seconds.

Tell Slotly your course, preferred times, and number of players. When a tee time drops, you'll be first to know. Auto-booking for golf is coming — notify-only access starts now.

Get early access

That class just had a drop. You're in.

Popular classes fill up instantly. Waitlist notifications go to everyone — only the fastest wins.

Slotly watches class schedules at your studio. When a spot opens, you're notified immediately. Auto-booking for fitness is coming soon. Join now to be first.

Join the waitlist

The reservation you couldn't get just opened.

That restaurant has been booked for three weeks. Tables cancel. You never see them.

Slotly is building toward dining. When it arrives, it will do for restaurant reservations what it already does for salons and boat clubs. Get on the list now.
