A publication about the systems beneath the guest experience.

OpenHospitality is written by Eric Cullenberg, a systems thinker and operator who has spent years building, running, and studying the technology layer behind hotels, inns, and short-term rental businesses. His work sits at the intersection of property operations, product design, and automation — with a steady focus on what actually improves the guest experience.

A hotel is not simply a collection of rooms and amenities. It is an operating system: reservations, staffing, housekeeping, revenue management, guest communication, and maintenance all flowing together in real time. When you see it that way, technology stops being a marketing add-on and becomes a design problem — one that determines whether guests feel cared for or processed.
