BUILDPLAN

sales-led; no disclosed pricing Design the Building

Web app (a Build AI module) that walks site setup through AI massing, feasibility (NOI/IRR/NPV/DSCR/Cap Rate), and a bill of quantities to an exportable PDF proposal. Localized for Japan (coverage/FAR/slant-plane zoning) and Mongolia; UI in Mongolian/Japanese/English/Korean. Sales-led with no disclosed pricing and no public API.
