Struction

Struction is an AI-driven end-to-end preconstruction platform for construction contractors and suppliers, using machine learning and computer vision to automate takeoff and quoting workflows. The platform enables contractors to generate accurate material takeoffs and supplier quotes faster than traditional manual methods, reducing time spent on preconstruction estimation. Struction is headquartered in Denver, Colorado, and was co-founded by CEO Joe Rainey. The company raised a $5M seed round in 2025 and its platform integrates across the preconstruction workflow from plan reading through quote generation, targeting the highly manual and error-prone estimation process that precedes construction project awards.
