Mission
To eliminate the structural inefficiencies that cost the architecture, engineering, and construction industry billions of dollars each year — by unifying every phase of the built environment lifecycle on a single intelligent platform.
Neural Architecture OS
Design, permit, and build — with AI-native spatial intelligence.
plinth.OS unifies generative BIM, interior & exterior spatial AI, live code compliance, autonomous permitting, real-time cost estimation, and post-occupancy digital twin handover in one connected neural data model.

Mission & Vision
Built to end bureaucratic friction in the built environment
Vision
A world where every building project — from client brief to occupancy certificate — flows through a single intelligent operating system, where permit delays are extinct and compliance is continuous.
Speed with Integrity
We automate without cutting corners. Every submission is accurate, every approval earned.
Radical Transparency
Clients, architects, and contractors see the same real-time data. No information asymmetry.
Compounding Intelligence
Every project makes the platform smarter. Our data flywheel is a public good for the industry.
End-to-End Ownership
We do not hand off. We own the outcome from brief to handover.
ROI as a Feature
Every dollar saved is measured, reported, and proven. We earn trust through evidence.
Product & Solution
Six-phase architecture operating system
The only platform that owns every stage in a single connected data model — from generative design through post-occupancy analytics.
Design
Generative BIM + VR. Upload an RFP; AI generates massing, site analysis (zoning, setbacks, solar, wind, noise), and 10+ layout variants with photorealistic renders and client VR walkthroughs.
Code Check
Live compliance overlays. IBC, ADA, and local codes checked continuously against the live model — errors surface and resolve in design, not at submission.
Permitting
Autonomous AI agent identifies agencies, fills forms, and submits to digital portals. City, county, state, and utility approvals run in parallel with ML timeline prediction.
Procurement
Real-time cost AI linked directly to the design model. Feeds the contractor bidding marketplace with pre-vetted specs.
Construction
Field doc automation for RFIs, submittals, and change orders. Field teams and project managers operate from the same live document set.
Handover
On occupancy, the project converts to a living digital twin. Post-occupancy data feeds back into future design intelligence.
Market Opportunity
One of the largest untapped opportunities in enterprise software
Global AEC software + permitting + construction management
AI-enabled design, permit, and field document platforms
US firms, 3-year capture at 10% SAM penetration
Live Product Demo
AI design cockpit — spatial intelligence, BIM sync, and autonomous handover
Generate development concepts, sculpt interior and exterior space, orbit live Three.js massing, validate compliance, estimate cost, sync Revit, and stream digital twin handover.
Demo runs on illustrative data; production deployments connect to live Revit, permitting, and IoT APIs.
Wedge: architecture firms pay first for generative design and code check; owners, GCs, and agencies join on the same project record.
Same six-phase workflow. Radically different economics.

Why Transit Plaza Tower works
Generative
Built for: Architecture firms
The tower anchors a TOD parcel with a porous plaza at grade, stacking 30% affordable units above retail so ridership, foot traffic, and housing policy align in one massing move.
Live code scan
Compliance checks
Rules engine
Built for: Architecture firms
Rules engine · pass ≥ 82 · warning 65–81 · fail < 65
Source: plinth.OS rules engine v0.1 — IBC demo overlays, ADA route checks, local zoning envelope
Transit overlay and plaza routes scan clean; tower egress is the one follow-up before permit set.
Aggregate confidence: 90 / 100
pass
Setbacks
Tower shaft sits 5.2 m inside the transit overlay envelope; plaza edge holds street wall.
96/ 100
pass
Height district
84 m roofline complies with TOD height bonus; mechanical penthouse within permitted bulk.
91/ 100

Accessible route
Plaza-to-lobby path maintains 1:20 max slope with two compliant landing zones.

Egress travel
Upper residential tiers need second stair confirmation before permit set issue.

Daylight access
Southwest plaza orientation preserves 62% of units above the preliminary daylight plane.
