Illoca operates a software platform that focuses on architectural design technology. Founded in San Ramon, US, the company has pivoted towards AI-native solutions to better serve design professionals.

This funding supports its mission to refine its design tools and expand its offerings to architecture firms. Illoca specializes in architectural design technology through its core product, Tracing Paper, an AI-native design engine launched to facilitate a more intuitive and efficient design process for architects and design professionals. This platform allows users to create and refine architectural drawings using natural inputs such as sketches and verbal prompts. Tracing Paper operates in two primary modes: Ideate, which transforms rough sketches into architectural drawings, and Iterate, allowing for real-time refinement through redlines and markups.

It integrates seamlessly with existing software like Autodesk Revit and Rhino, serving a diverse clientele in North America, Europe, and Asia. Illoca generates revenue primarily through subscription-based pricing plans for its Tracing Paper service. The pricing structure includes a Free plan with 100 monthly credits, an Explore plan at USD 29. 99 per user per month, and a Team plan starting at USD 59.

99 per team member per month. The Enterprise plan, available at custom pricing, includes tailored features. Revenue is derived from the consumption of credits for high-value tasks such as image generation and floor plan creation, charging users only when the system performs these actions. In May 2026, Illoca raised USD 13 mn in Seed funding led by Bessemer Venture Partners, which will be utilized to develop its design platform, enhance tools for creating design documents, and support product rollout to architecture firms.

The company is focused on expanding its offerings and plans to target additional markets, although specific regions have yet to be disclosed.
