Overview
Build Technologies provides an AI-native platform for real estate and infrastructure that uses a multi-agent AI system, Dougie, to automate the entire commercial development lifecycle for institutional clients. The platform ingests data from more than 1,600 sources and uses a hierarchy of specialized agents, coordinated by LangGraph, to handle site selection, due diligence, power assessments, permitting, and pre-construction design, letting agents research markets, analyze properties, and generate financial models. It differentiates itself with end-to-end, autonomous workflow automation for complex development projects, marketed as agentic real estate and aimed at governments, developers, and investors. Its goal is to accelerate and automate large-scale development work and grow its engineering footprint in North America and Europe, acting as an AI operating partner for its clients.
