Our mission

AI that speaks the language of the job site.

Why we exist

Construction runs on estimates, schedules, and decisions made in the field. Most software doesn’t. We’re building AI that understands waterline and sewer, pipe and trench, labor and equipment—so contractors and teams can plan, bid, and run jobs on solid ground.

What we’re building

Rockmud is in development. We’re starting with cost estimation and an assistant that can answer construction questions and help run numbers. Our goal is to make AI a practical tool for every phase of the job, from bid to closeout.

Contech API

Our estimation and assistant engine is available as an API for integration into your own tools and workflows. The Contech API provides cost predictions, confidence ranges, and a chat assistant trained on construction context.
