AI Startup · Toronto, Canada (In-Person downtown Toronto)

About Us

We're solving one of the largest problems in the physical world: housing that's too slow and too expensive to build. The $2 trillion construction industry runs on human expertise that doesn't scale - so we're building the AI that understands what to build and how to build it .

We start with the costliest problems for general contractors - the multi-million-dollar decisions that Claude cannot solve. Tyce Agent wins more projects and estimates costs on multi-million-dollar builds live at one of the landmark construction companies today.

We just closed a 7-figure round and are hiring to build the best AI platform for construction.

We offer competitive salary and equity.
