About Build

We founded Build with a simple thesis: agentic AI is going to fundamentally change how the Built World gets developed. In 2024, we started as a two-person team with a radical vision—pairing expert labor with specialized AI agents to automate and accelerate the traditionally expensive, multi-year development process. Through heavy context engineering and deep domain understand channelled through our commercial partners, we built the highest-quality product ever targeted toward developers. The spirit from those days remains.

Today, Build is defining agentic CRE (commercial real estate)—the world’s first truly agent-driven development platform. Our AI agents are embedded in the workflows of some of the largest investors, developers, and operators in the Built World, accelerating projects across asset classes including digital infrastructure, industrials, telecommunications, and residential. Our engagements collectively represent nearly $3T AUM, and we are rapidly expanding operations across San Francisco, London, and soon New York.

Our mission is to empower the world’s best builders by unleashing the power of intelligent automation. Our team of engineers (“Builders”) and experts (“Architects”) ship fast and innovate directly with clients.

That’s where you come in.
