Four ways to build HOS with us.

Each path starts with a short conversation. Sending a form commits you to nothing: no payment, no confidential data, and no exclusive rights for anyone.

For hotels and PMS vendors

Pilot partner

Bring a hotel or a platform, authorised access to its systems, and the people who can tell whether HOS gets arrivals right.

For organisations shaping HOS

Founding member

Bring business and technical expertise, and financial support at levels that will be published openly.

For developers and integrators

Technical contributor

Help build the standard in the open: data formats, PMS mappings, tests or documentation.

For funders

Financial patron

Fund the shared work. Patrons get no special vote, data access or certification advantage.
