Illoca

What Illoca does

Illoca, Inc. is a venture-backed AI startup founded in 2024 that builds Tracing Paper, an AI-native design engine targeted at professional architects and AEC practitioners. The product converts rough sketches, hand markups, and natural-language prompts into editable 2D floor plans and BIM-compatible 3D massing models in real time, structured around a "Human-in-the-Loop" philosophy in which licensed professional judgment remains the final arbiter. Tracing Paper's feature surface spans five named modules — Augmented Sketch, Adaptive Massing, Prompted Plans, Agentic Refinement, and Instant Facades — and the platform is designed to export high-fidelity work directly into Autodesk Revit and Rhino rather than replace the standard CAD/BIM toolchain.

Under the hood, Tracing Paper is a multimodal generative system that processes sketch, image, and text inputs and emits parametric geometry rather than static pixels, with AI agents executing layout edits in response to markup intent. The company was co-founded by researchers from Google DeepMind and Autodesk's AI Lab and former Tesla BIM leads, which underpins both the modeling capability claims and the interoperability focus. The firm does not use customer sketches, prompts, or project models to train its underlying models and offers zero-data-retention options for enterprise customers.

Commercially, Illoca runs a self-serve SaaS motion layered with a usage-based credit mechanic and a field-sales enterprise tier. Plans are publicly disclosed at $29.99 per person per month (Explore, 3,000 credits) and $59.99+ per team per month (Team, pooled usage with SSO and license management); enterprise pricing is custom and includes bespoke agents, expanded usage, SLAs, and 24/7 priority support. Customers primarily sign up directly at app.illoca.com, with a 1,000-credit starter pack for new users and a free tier that refreshes 100 credits per month. The company is headquartered at 3001 Bishop Drive, San Ramon, California, was capitalized with a $13 million seed round in May 2024 led by Bessemer Venture Partners with participation from AIX Ventures, Root Ventures, and Alt Ventures, and operates with 51–100 employees.

Core offering

Illoca sells Tracing Paper, an AI-native generative design engine for architects delivered as a cloud SaaS platform. The product accepts hand sketches, spatial diagrams, markups, reference images, and natural language prompts, and converts them in real time into editable 2D floor plans and BIM-compatible 3D massing models that can be exported into Autodesk Revit and Rhino. It is offered via freemium, individual ($29.99/month), team ($59.99+/month), and custom-priced enterprise subscriptions, with usage-based credits consumed for high-value AI tasks.

Product overview

Illoca offers a single unified product called Tracing Paper, an AI-native design engine for architects. Tracing Paper provides multiple interconnected AI-powered design modules including Augmented Sketch (sketch-to-floor-plan conversion), Adaptive Massing (2D to 3D massing generation), Prompted Plans (natural language floor plan generation), Agentic Refinement (AI-driven layout editing), and Instant Facades (facade exploration). The platform operates as an intelligent canvas that replaces traditional CAD toolbars with a workflow mirroring how design studios work, supporting both ideation and iteration modes.

Partnerships

Three partnerships are on record, tiered core and supporting.

• Autodesk (Revit)coreTechnology or IntegrationTracing Paper is designed to export high-fidelity work directly into Autodesk Revit. The platform generates 2D and 3D building models that are BIM-compatible and compatible with software like Revit, meeting architects in their current workflow.
• RhinosupportingTechnology or IntegrationTracing Paper generates outputs compatible with Rhino (alongside Revit), enabling interoperability with existing CAD/BIM ecosystems used by architects and engineers.
• Stripe, Inc.supportingTechnology or IntegrationStripe is used as the payment processor for Illoca's paid services, handling payment processing under its own terms of service and privacy policy.

Direct peers

• Snaptrude: AI-native 3D building design platform that lets architects design, document, and detail in a single browser-based environment. Most directly comparable to Illoca in approach, target customer (architects), and the use of real-time AI to produce structured 2D/3D design output.
• TestFit: AI-powered real estate feasibility and architectural design platform that automates site planning, unit mix, parking layouts, and massing studies. Directly comparable to Illoca's Adaptive Massing and Agentic Refinement features for AEC professionals.
• Hypar: Generative building design platform that enables architects to generate and evaluate building options using cloud-native, parametric tools. Shares Illoca's focus on AI-driven, structured outputs and integration with downstream BIM tools.
• Arcol: Architectural design automation tool that helps architects generate code-compliant building designs faster, including automated zoning and code checks. Direct overlap with Illoca's value proposition of automating production-grade architectural documentation.
• Maket: Generative AI platform for residential architecture and interior design that produces floor plans, renderings, and 3D models from natural language prompts. Closely comparable to Illoca's prompt-driven design workflow and AI-first positioning for design professionals.

Broad incumbents

• Vectorworks: Provider of CAD and BIM software (Vectorworks Architect) widely used in architecture, landscape, and entertainment design. Another established AEC software incumbent whose design community could be a target customer—or competitor—for Illoca.
• Graphisoft: Maker of ArchiCAD, a major BIM platform competing with Revit in the architectural design market. Represents an alternative AEC incumbent whose installed base of architects could be a future Illoca integration target—or a competitor adding AI features.
• Autodesk: Dominant AEC software provider behind Revit, AutoCAD, and Forma (acquired Spacemaker). The platform Illoca integrates with—and the single largest competitive threat, as Autodesk could ship competing native AI features inside the tools its customers already pay for.
• Bricsys: Maker of BricsCAD, a DWG-compatible CAD/BIM platform positioning itself as a cost-effective alternative to AutoCAD/Revit. Another AEC incumbent in Illoca's competitive landscape with the engineering base to bundle AI design features.
• Trimble: Provider of AEC software (Tekla, SketchUp, Trimble Connect) and construction technology. A broad incumbent with the scale, capital, and customer relationships to enter the AI-architecture space or partner with Illoca-style specialists.
