That Open Company has opened registration for the That Open Platform launch, with the launch window scheduled for June 22, 2026. The page describes That Open Platform as a place to “build, connect and operate” AECO software, positioned around the open technology already used by BIM applications and developers.
The launch registration offers a private walkthrough video, the launch date, and a chance to become a founding member. The page says the platform is aimed at BIM managers, digital leads, architecture, engineering and construction firms, AECO software developers, and innovation or digital strategy teams who need software that better reflects their workflows.
For free software and openBIM users, the interesting part is That Open’s continued shift from individual browser-based BIM components toward a broader platform for building custom AECO applications. The launch page connects this to the company’s existing open technology base and community of AECO software developers.
