At Terra Firma, we’re redefining how the world moves earth for construction. Founded by former Space

X engineers and backed by Bain Capital Ventures, Terra Firma is automating construction to make it faster, cheaper, and safer.

At Space

X, we were part of the teams that built the largest rocket in human history, launched the largest constellation of satellites ever made, and delivered connectivity to millions of people worldwide. What we learned was simple: infrastructure is everything.

At Starbase, the biggest barrier to launching missions to Mars was not building the rocket. It was how slow, expensive, and complex it was to build the infrastructure around it. We lacked buildings, roads, water, power, communications, and waste management, and constructing them took far more time and resources than it should have.

From a first‑principles perspective, that doesn’t make sense. It shouldn’t be this hard or costly to create the foundations for progress. That’s when we realized something important: the same engineering mindset that enabled us to tackle space exploration and mass manufacturing could be applied to infrastructure. By bringing the principles of simplification, iteration, acceleration, and automation to construction, we can unlock a new era in how the world builds.

Accelerating infrastructure unlocks progress across every domain, creating a self‑sustaining engine for tackling humanity’s toughest challenges. The innovations we develop on Earth will lay the groundwork for the technologies that one day make settlement on Mars possible.

Design, prototype, and deploy rugged electromechanical systems that integrate precision mechanical design with robust electrical components. Develop enclosures, actuators, linkages, and wiring harnesses built for extreme conditions. Collaborate with multidisciplinary teams to rapidly prototype, test, and refine systems for reliable real‑world performance.
