Illoca is a software platform that focuses on enhancing architectural design processes through technology. The company is headquartered in San Ramon, California, US. Founded by a team with experience in technology and design, Illoca has seen significant evolution in its business strategy, particularly with the development of its Tracing Paper product.

In May 2026, Illoca raised USD 13. 00 mn in Seed funding led by Bessemer Venture Partners, with participation from AIX Ventures, Alt Ventures, and Root Ventures, marking its first deal. Illoca’s primary offering is Tracing Paper, an AI-native design engine tailored for professional architectural practice. This intelligent canvas facilitates the design process by allowing users to sketch, markup, and iterate ideas seamlessly, bridging the gap between creative exploration and technical production.

With two operational modes—Ideate and Iterate—users can transform rough sketches or verbal prompts into architectural drawings, refining their concepts in real time. Tracing Paper supports professionals in architecture and design sectors, catering to individual architects, design studios, and enterprise-level firms, with a clientele across North America, Europe, and Asia. Illoca operates on a subscription-based revenue model, providing tiered pricing plans that cater to a range of users. The offerings include a Free plan with 100 monthly credits, an Explore plan at USD 29.

99 per month with expanded capabilities, and a Team plan starting at USD 59. 99 per month, designed for collaborative efforts. Additional enterprise-level solutions customize pricing based on specific client needs, ensuring greater security and tailored features. Transactions are structured around the consumption of credits for high-value tasks performed by the Tracing Paper engine, allowing clients to only pay for the output they utilize.

This model positions Illoca as a premium provider within the architectural software market. Illoca plans to utilize the recent Seed funding of USD 13. 00 mn to develop its design platform further and enhance tools for creating design documents. The company aims to support the rollout of its products to architecture firms, with plans for expanding into new markets and geographic regions, particularly targeting additional locations in Europe and Asia by mid-2027.
