Who it's for

Built for the project team — not a single seat

Architects and designers own the model. Developers need portfolio predictability. Owners need occupancy visibility. Same six phases — framed for how you work.

Architects

From programming and AHJ research to a signed permit package — without re-keying zoning logic across tools.

View architects page →

Developers

See permit risk and cost early — then track change orders and condition close-out through construction across the portfolio.

View developers page →

Owners

Stay current on permit status, construction close-out, and occupancy readiness — without running the day-to-day model.

View owners page →

Mission & Vision

Built to end bureaucratic friction in the built environment

Mission

Eliminate structural AEC inefficiencies by unifying the built-environment lifecycle on one platform.

Vision

Every project from brief to occupancy runs on one OS — permit delays extinct, compliance continuous.

Speed with Integrity

Automate without cutting corners on accuracy.

Radical Transparency

Same real-time data for every project role.

Compounding Intelligence

Filings improve compliance patterns using Data with all identifying project/client details removed and combined across many projects — not traceable back to any one firm. Training on your design schemes requires explicit written opt-in — see Trust & Liability..

End-to-End Ownership

Own the outcome from brief to handover.

About us

What is plinth.OS?

plinth.OS is an AI-native operating system for architects, designers, developers, and owners — the six-phase connected record.

Instead of re-keying zoning logic, life-safety sheets, and permit narratives across separate tools, teams generate massing, validate code, prepare agency-ready packages, estimate cost, and hand over a living twin on one connected record. Works with Revit via Autodesk Construction Cloud, or through Open, non-proprietary file formats for building design data — an alternative to being locked into one software vendor. when you do not run Revit.

One connected record

All six phases share one connected record — no dropped handoffs.

Built for the project team

Purpose-built for architects and designers who own the model, and for developers and owners who need the same record as programs scale.

Human sign-off, AI speed

AI accelerates prep and checks; licensed professionals review and sign before anything is filed.

Trust

Security & Trust

Architecture firms trust us with client sites, proprietary schemes, and pre-submission permit packages. Here is how we handle that responsibility before you roll out firm-wide.

Security

SOC 2 Type II · Q1 2028

Production tenants run with TLS 1.2+, encryption in transit and at rest, role-based access controls, audit logging, and annual penetration testing. Enterprise prospects can request our security brief and control matrix ahead of the Q1 2028 audit target (post seed close).

Data ownership

Customer-owned intellectual property

Your briefs, massing, drawings, and permit packages remain yours. plinth.OS does not claim ownership of project geometry, resell client work, or train public models on your schemes without explicit written opt-in.

Starter can process geometry and permit prep ephemerally in-session without long-term retention. Studio and Enterprise store encrypted project records in United States cloud regions by default, with export on request and retention policies you control.

GDPR

US-hosted today · EU residency roadmap

GDPR-aligned data processing terms are available for international firms. We provide a Data Processing Agreement and subprocessor list for information technology review.

Human sign-off before filing

Otto, your AI permit agent, prepares agency-ready packages; a licensed architect, expeditor, or firm reviewer signs off before submission. AI flags conflicts and missing artifacts — it does not replace professional judgment or stamp drawings.

Traceable compliance decisions

Every code check records the rule, score, and model state that produced it. Firms can export the compliance narrative with the package for internal QA and jurisdiction review.

Insurance

Under active review

E&O coverage is under active review ahead of Studio-tier rollout. Firms retain professional liability for stamped work; plinth.OS covers platform delivery and data handling under our service terms.

Jurisdiction variance

Los Angeles live · others human-routed
Where agencies require mail, counter, or hybrid intake, the platform routes through A specialist who manually walks permit paperwork through a city or county agency. or firm reviewers. Live digital portals (Los Angeles today) still require human confirmation before submit.

Who signs the permit package? plinth.OS is built for human review, jurisdiction-specific workflows, and clear accountability — not autonomous filing without oversight.

Business Model

Revenue aligned with client outcomes

Starter is the design beachhead for architects and designers — upgrade to Studio when permitting, procurement, and ROI visibility matter. Studio base $36,000/yr ($3,000/mo) plus success fees on approvals — modeled ACV blends higher with filing volume · ~78% gross margin (modeled).

How firms adopt plinth.OS

One project first. Firm-wide when it proves out.

  1. 1

    Start one project on Starter

    Free tier — no contract, no IT setup. Run generative design and compliance on a live brief in minutes.

  2. 2

    Test Otto via pay-per-filing

    Run one real project through Otto ($500 per filing) when permitting matters — before any firm-wide Studio rollout.

  3. 3

    Roll out firm-wide on Studio

    Standardize on Studio once ROI is visible in the dashboard — seats scale across active projects.

  4. 4

    Scale on Enterprise

    Multi-jurisdiction, unlimited projects, and white-label when the portfolio needs one connected record.

Personalized estimate

What could your firm save?

Based on $31K average cost per permit delay Building Industry Association of Washington estimate, via NAHB “Blueprint to Address the Housing Affordability Crisis,” Jan 2025. Washington State average — not a national or LA-specific figure. and an estimated 35% reduction in delay exposure.

This estimate uses a Washington State industry benchmark ($31K/permit delay, BIAW via NAHB) applied against a projected reduction rate. It is not based on LA-specific or plinth.OS cohort data yet, and should be treated as a rough industry-context estimate — not a guaranteed or verified outcome.

Example: 12 permits/year at $8.00M average project value ≈ $137K estimated annual savings.

Positioning

Purpose-built for the six-phase project record — not general-purpose platforms

Most tools stop at design — and leave permit prep as a manual handoff. plinth.OS is built for architects, designers, developers, and owners who need the six-phase connected record.

Most tools cover one part of this process — plinth.OS covers all of it, from pre-design through handover.

Under-50-staff practices

Sized for the firms enterprise suites price out — where principals still own permitting, not a separate department.

Design through handover

One workflow across the six phases — instead of re-keying zoning logic across three tools before every filing.

Portable by default

Works with Revit when you have it, and through IFC and open BIM when you do not — one connected record stays yours.

Permit data flywheel

Every filing improves jurisdiction-specific compliance patterns using de-identified, aggregated data.

Deeper with every project

Each filing reuses jurisdiction context and compliance logic — so the second project moves faster than the first.

ROI as a feature

The platform tracks time and dollars saved per project — so renewal is tied to measured outcomes, not shelfware.

Founder & CEO

Amir Duke is the founder and CEO of Plinth.OS. After recognizing the gap between Spatial AI Intelligence and the Architecture Industry, he created a SaaS product to give architects real-time generative BIM, live compliance, and Otto for human-reviewed permit prep on one connected record without asking them to give up licensure or sign-off control.
