About
Built by a team with AEC field experience.
Engineers and AI researchers who have worked inside the industry — building tools grounded in real operational context.
Our story
Building for individuals
BIBIM AI was built to answer a gap that field engineers and BIM practitioners felt daily: generic AI tools with no knowledge of the tools, formats, or conventions that define real BIM work. BIBIM brought natural language → code → execution natively into Revit, Dynamo, and ArchiCAD. Apache 2.0, BYOK, no server. On launch, it reached the weekly top of r/BIM — confirming demand that had no outlet.
Building for teams
Enterprise BIM teams face a different class of problem: bottlenecks that are structural, domain-specific, and invisible to outside tooling vendors. SquareZero's approach starts with the problem — defined together with the team, not handed down by a vendor. A first working build follows in a month, then a continuous loop of refinement. Five tracks are currently active across Korean and Austrian enterprise BIM teams.
Building for everyone
Drawing on the cumulative problems solved across our solution tracks, an integrated BIM tool for AEC is slated to enter development — purpose-built for every member of the team. Fast, practical, and effortless to use. The accumulated context from Phases 1 and 2 is what makes it possible.
Team
In-house: BIM engineers, site practitioners, AI researchers.
