What we make
One Third Ceiling makes open file formats and the tools that love them. Your books, your lists, your teaching cases — in files you can read, share with anyone, and keep forever. Our apps are the best way to use them; they’ll never be the only way.
Why open formats
The things families and teachers make with software — a child’s library with a grandparent’s voice in it, a list kept for years, a teaching case — should outlive any app, any platform, and any company, including ours. Everything we build saves to plain, documented files that will still open decades from now.
Apps
Our first titles are in family testing now and arriving soon. If you’d like to hear when they launch, write to us.
