Mighty Buildings

Mighty Buildings is a construction technology company based in Oakland, CA that is innovating the construction industry by creating beautiful, sustainable, and high-quality homes using advanced materials, patented 3D printing technology, and robotics automation.

Our 3D printing technology allows us to produce modular houses and building components for our clients much faster than traditional construction.

Our 3D printers use a thermoset composite material we invented called Light Stone Material (LSM), which hardens when exposed to UV light, making it a more robust building material.

Mighty Buildings has a near-zero waste production process, preventing 1,100 - 2,000 kg of CO2 emission per 3D printed home. We are committed to achieving Net-Zero by 2028 - making our company 22 years ahead of the construction industry.

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

We are backed by several notable International and Silicon Valley tech investors, including Khosla Ventures, Zeno Ventures, and Y Combinator.
