About Clock

We’re an independent hotel software company.

We’ve been building for hotels since 1996. Same field. Same focus. Same belief: hotel software should make the work calmer, clearer, and easier to trust.

How we think

We don’t build for demo day.

We build for Tuesday — when the lobby is full, a group arrives early, the phone won’t stop ringing, and the team still needs the system to hold up.

In hotel software, quiet is success.

We stay independent so we can think long-term, say no when we should, and improve Clock steadily instead of chasing every trend. We prefer useful progress over big reveals, clear defaults over endless options, and practical tools over software theater.

Our job is not to make hotel software feel impressive. It is to make hotel work feel easier to run — every day, especially the busy ones.

That same thinking shapes how we run Clock, too, and we wrote more about it in How we run Clock.

From one founder to another

We are a profitable, privately owned company — independent, just like most of the hotels we work with. We started building PMS software in 1996, and hotel software is still the only business we are in. Clock is owned and managed by its founders.

In a world where many hotel tech vendors have become enormous corporations and money machines, we believe independent hotels need something leaner and more approachable — a company that understands your daily challenges because we live them too.

A company you can rely on to help level the playing field against the big players.

That is why we focus on building software that truly serves hoteliers, not investors. No forced upsells. No sudden price changes. Just reliable tools that work day after day.

In their words

How do customers feel after switching to Clock?

We asked our customers: What changed for the better since you switched to Clock? Here’s some of what they said…

We chose Clock because of the tool's flexibility, its ability to integrate with our entire IT ecosystem, and also for its multi-property management, which is really the strong point for us.

Marine Bossanne Project Manager Operations and Quality at Elegancia
The strength of Clock is that it brings everything together in one system. What we previously had to accomplish using multiple tools, we can now do with a single solution.

Ruggero Carpino Head of Customer Service & Training at Algilà Ortigia Charme Hotel, Syracuse
It was very important for us to look at the stability and the future proofness of the system. And Clock is a company that has the knowledge and the expertise.

Steff de Groot Owner & General Manager, WICC Hotel & Congress Centre
Faster processes, faster training, more time for staff, to focus on the guests, and tasks that used to be done manually are now automated.

Carsten Werblow Head of Operations Gambino Group
Better price management, a comprehensive system API, and a dynamic company that continually develops the software.

Marco Coppola Owner & Chief Navigator Officer, The YellowSquare
By automating routine processes with Clock, we were able to completely restructure how our staff spends their time. Now, the efforts are focused on more meaningful and more profitable activities.

Lyubomir Stamboliyski Commercial Director of St. Constantine & Helena Holding
Technologies are advancing, and it's normal to move our data to the cloud. I was firmly convinced that this is the right path, and I think we made the right decision.
