Summary
Illocа, an AI-native design platform headquartered in San Ramon, California, has closed $13 million in Seed financing led by Bessemer Venture Partners, according to a GlobeNewswire announcement dated May 6, 2026. AIX Ventures, Root Ventures and Alt Ventures also participated in the round. The company is co-founded by CEO Chin-Yi Cheng and COO Chiaowei Yu.
The company frames its opportunity around a structural inefficiency in architecture, a sector within a $12 trillion global construction industry. The announcement states that architects spend 60 percent of their workweek producing, translating, reformatting and rebuilding existing work, equating to more than 1,300 hours lost per architect. The company argues that most design software cannot interpret architectural intent, which discourages iteration.
Illocа's first product, Illoca Tracing Paper, replaces conventional multi-button design toolsets with a collaborative canvas. Architects can work through sketches, markups and natural language, while AI agents generate 2D and 3D designs in real time. According to the company, the product is already in use with early partner Kajima Corporation. Yasuhiro Nakano, Chief Architect at Kajima, said the team can iterate through multiple options with significant speed while preserving architectural intent. The company says its platform can turn weeks of design work into days.
Bessemer Vice President Maha Malik said the firm sees architecture as a discipline constrained by legacy software and described the company's approach as bridging high-level intent and professional-grade execution. The founders have backgrounds in AI research and building information modeling, including work at Google DeepMind, Autodesk AI Lab and Tesla. The announcement does not disclose valuation, the round's full investor syndicate beyond the named participants, or revenue metrics.
