Origin, a startup developing artificial intelligence-powered robots for construction, has raised $20 million in funding to expand the deployment of its flagship OG-1 robot and scale its operations in international markets. Accel and Zacua Ventures co-led the funding round, which also attracted investment from Unilazer Ventures, Schema Ventures, Z21 and angel investors associated with companies including Anduril, Skild AI, 1X and Tesla.

The company emerged from stealth in October 2026, introducing its approach to automating interior construction work. The fresh capital will support the expansion of Origin’s robot fleet, customer deployments and large-scale pilot projects in the United States and Europe. The company also plans to conduct pilots in Germany, Sweden, France and Saudi Arabia and extend its technology to additional interior construction trades.

Origin’s flagship OG-1 robot is designed to perform multiple tasks on a single platform. According to the company, it can autonomously complete wall-finishing workflows, including applying compound, sanding surfaces and priming walls.

The robot operates on a three-wheeled platform with a 360-degree view of its surroundings and can work at heights of up to 14 feet. It uses real-time force control to maintain consistent pressure during contact-intensive tasks such as sanding. Origin says the system is designed to operate alongside construction crews while other work continues on-site.

The technology is powered by Origin’s Construction Action Model, a foundation model developed specifically for construction. Its architecture combines a reasoning system to plan tasks, an action policy to guide navigation and tool use, and a controller that translates decisions into precise physical movements.

Investors see construction as a major potential market for physical AI, where robots could take on repetitive and labour-intensive activities. Vivin Hegde, founding partner at Zacua Ventures, highlighted the importance of building robots that can perform reliably on live construction sites rather than only in laboratory settings. Accel investor Anagh Prasad also pointed to the potential of AI systems developed specifically for construction workflows.

With the new funding, Origin aims to move beyond development and expand real-world deployments. The success of its strategy will depend on how reliably its robots perform across different job sites, integrate with construction teams and scale commercially.
