Four things. (1) Independent — not owned by an OEM, hyperscaler or capture-hardware vendor, so we don't lock you into a single ecosystem. (2) Scan-agnostic — we ingest 10+ scan formats from any reality-capture device you already own, instead of forcing a proprietary capture pipeline. (3) Deploy-anywhere — the same binary runs in our cloud, your VPC, on-prem or fully air-gapped, so your spatial data stays where compliance demands. (4) Persistent — MultiSet is a headless, horizontal VPS layer where anchors and annotations live in the map and survive every re-scan, so map operations stay routine instead of being rebuild-the-world events.

GPS fails indoors and below dense canopy. Wi-Fi and Bluetooth beacons reach 1–5 meter accuracy at best and require infrastructure. QR codes work only at the marker. MultiSet's VPS uses the camera you already have to deliver centimeter-accurate 6-DoF pose continuously — anywhere the camera can see, with no installed infrastructure.

MapSet stitches every individual scan — LiDAR, photogrammetry, 360° video, Gaussian splats — into one continuous coordinate system. Devices localize across rooms, floors, indoor-outdoor transitions and separate buildings without "map islands" or re-localization. Hierarchical indexing keeps lookups under 52 ms median and < 1 cm drift at 10 m, scaling to 10,000 m²+ footprints.

MultiSet treats your map as durable, versioned infrastructure — an API-first map infrastructure your spatial workflows build on top of. Anchors, annotations and content live in the map and persist across every version, so when a facility changes you re-scan to refresh; you never re-author. Delta updates ship as map updates without SDK redeploys. Map versioning includes rollback, full audit trails and rate-of-change analytics across versions. Map operations are routine, not rebuild-the-world events — which is why MultiSet works for environments that actually change: construction sites mid-build, manufacturing floors mid-retrofit, retail mid-reset, warehouses mid-expansion.
