Our mission
Make every indoor space as effortless to navigate as the open road — one platform, any venue, zero hardware.
The indoor intelligence platform
Navigation that doesn't stop at the front door.
GPS gets you to the building. TERRIN takes over from there — turn-by-turn wayfinding, live footfall, and store-level intelligence for the spaces satellites can't see. No hardware. Just software.
The blind spot
17 billion square feet where GPS goes dark.
People spend ~90% of their lives indoors, yet the moment they step inside a mall, airport, or hospital, the map goes blank. Operators fly equally blind — no idea how people move, where they linger, or where they get lost.

Why we exist
We're drawing the map for everywhere GPS can't reach.
Outdoor navigation was solved two decades ago. Indoors — where people actually spend their days — it never was. TERRIN finishes the map.
Where this goes
A world where no visitor is ever lost indoors, and every venue understands itself — in real time, down to the aisle.

How it works
From floor plan to live navigation in four stops.
Follow the footsteps — experience TERRIN the way your visitors will.
1
For venue operators
Map the space
Upload floor plans. TERRIN converts them into routable, multi-floor digital maps — no beacons, no rewiring.
2
Indoor positioning
Position without hardware
Our software fuses existing signals and motion to locate visitors indoors, accurate to the aisle.
3
Real-time experience
Guide every visitor
Shoppers get turn-by-turn routing to any store, exit, or amenity — rerouting live as they move.
4
Business intelligence
Learn from every step
Every journey streams back as footfall, dwell, and flow intelligence for the operator.
A venue that finally understands itself.
Visitors who never get lost. Operators who finally see. That's the destination.
Request Early AccessOne platform, three audiences
An ecosystem that runs the whole building.
The same maps and intelligence, surfaced for the people who run venues, the operators who own them, and the shoppers inside.
Built for every venue
If it has walls, TERRIN can map it.
One platform adapts to the way each kind of venue actually moves people.

Investment opportunity
One of the last unmapped frontiers.
Outdoor mapping built generational companies. The indoor equivalent is still wide open — and it's a software problem, not a hardware one.
Greenfield market
17 billion sq ft of indoor space and ~90% of human time, with no dominant platform yet.
Software economics
No beacons, no hardware to install or maintain — venues go live in days, and margins scale like software.
Compounding moat
Every navigated journey sharpens positioning and venue intelligence — a data advantage that grows with use.
Year-3 target: 2,000+ venues. Full market model, roadmap, and projections are in the deck.
