About Mantle Place.

Mantle Place is a spatial data broker for AECO professionals — architects, engineers, construction managers, and operations / land-development teams. You draw an area of interest on a globe, see a deterministic price, pay, and own the resulting terrain-plus-imagery-plus-basemap bundle forever in a Cloudflare R2 vault.

No streaming subscription that vaporizes on cancellation. No procurement conversation for a $20 site model. No hunting across NAIP STAC + Mapterhorn + Protomaps for the pieces and stitching them yourself.

Mantle Place LLC is a Delaware company operated by Coulter Heiberger, a visualization practitioner with AEC industry experience. The platform is firewalled from his full-time employment to preserve IP ownership; mantle.place exists as a separate commercial entity.

Mantle Place started as a personal frustration: site-context data for visualization and early-design work was fragmented across half a dozen agency portals, gated by opaque licensing, and shipped in formats that didn't drop cleanly into Rhino / Revit / Blender / Unreal. The platform is the version of that workflow that should have existed.

Curators own what they buy. Purchased bundles live in your R2 vault permanently, with re-mintable presigned download URLs. If we change pricing, you keep your old bundles. If we go out of business, you have the files.

Pricing is honest and computable at draw time. A floor plus a per-km² curve — no metering, no usage tiers, no per-seat math. You see the price before you commit.

Licensing is visible at the decision point. Every bundle ships with an attribution PDF and a machine-readable attribution JSON. The full Produced Works architecture is on the Licensing page.

The stack is open as far down as we can take it. Sovereign basemap (Protomaps planet PMTiles mirrored to R2), open data sources (NAIP, OSM via Protomaps, Copernicus via Mapterhorn), open-source UI primitives, open-source storage format. See the Attributions page for the full list.

v1 ships three providers — Protomaps (global basemap), NAIP (US aerial imagery), and Mapterhorn (global terrain). v2+ candidates include Sentinel-2 for global imagery, USGS 3DEP for sub-meter US elevation, Overture / OpenStreetMap for richer features, FEMA for flood hazard, and a Cesium-for-Unreal-ready 3D Tiles output. The full roadmap lives in the manifesto.
