BOxCrete uses Gaussian Process regression trained on 500+ strength measurements across 123 unique mixes. In a real deployment at a Minnesota data center, the model produced a mix that reached full strength 43% faster while cutting embodied carbon. This is not a general productivity tool. It is trained on curing intervals, slump measurements, and material grades that only a concrete engineer would understand.

Rebar ingests construction blueprints and spec books to generate equipment quotes for HVAC, electrical, and plumbing suppliers. CEO Evan Brown spent years as a hands-on HVAC estimator, printing blueprints and using rulers to build equipment lists manually. The company doubled ARR in the first six weeks of 2026.

Co-founded by former OpenAI chief research officer Bob McGrew, Arda builds a video model that watches raw production floor footage to learn how tasks are performed, then coordinates machines and humans across the full line. The pre-revenue valuation is one of the clearest signals that capital markets are pricing the physical AI opportunity aggressively.

AI agents that review mechanical, electrical, and plumbing drawings for coordination errors before construction begins. Co-founder Brandon Abreu Smith was recruited at 17 by a US contractor for deep RL work on pipe routing and spent six years building AI inside construction firms before co-founding the company at Oxford.

Evaluates 10,000+ scheduling combinations per second to assign the right technician by skills, location, and real-time availability. Built specifically for HVAC, plumbing, electrical, and cleaning contractors. The specificity is the product: a plumber and an HVAC tech are not interchangeable, and this tool enforces that by design.
