Who we are

We are a construction technology company based in Oakland, CA that is innovating the construction industry by creating homes that are beautiful, affordable, and sustainable using 3D printing, robotics, and automation. Our 3D-printing technology allows us to produce modular houses and building components much faster than traditional construction. Our 3D printers use a thermoset composite material we invented called Light Stone Material (LSM), that hardens when exposed to UV light, making it a more effective building material.

Not only we are certified under California’s Factory Built Housing program to build units using 3D printing, we are also the first company to achieve certification under the UL 3401 standard for evaluating building structures and assemblies.

We are backed by notable top-tier venture capital firms such Khosla Ventures, Y Combinator, SV Angel, CoreVC, and more.
