About us
About the team
Geom is a team of architects, homebuilding operators, and AI engineers who have worked together across multiple startups and industries. We've built companies, products, and teams together before, and bring a shared understanding of what it takes to turn ambitious ideas into tools that work in the real world.
We started Geom because production homebuilding runs on real-world complexity: national standards, regional and division variation, sales option workflows, and product catalogs carrying years of revisions in CAD. That complexity is handled today by skilled people doing repetitive translation, checking, and drafting work.
We're not trying to replace the design process. We automate the repetitive work around it — inside the tools, file formats, and data homebuilders already use, so teams keep their standards and their process while the manual work in between disappears.
