Fuller is the build layer. When Prism has identified a problem worth solving and Reverberation has articulated what the solution needs to be, Fuller makes the thing. Products, tools, software — the work of turning honest engagement with a real problem into something a person can actually use.

The name carries intentional weight. Buckminster Fuller built things that worked with the world as it is, not as it theoretically should be. He understood that the most effective design is the kind that solves a real constraint rather than an imagined one. That's the operating principle here: build from what's actually needed, not from what would be impressive to build.

Fuller is TBG's primary product entity. The tools it builds are designed without dark patterns, without feature bloat, and without the assumption that the person using them has more time, energy, or cognitive bandwidth than they actually do.
