Offsight.

A building, it turns out, is just a very large product that nobody was tracking properly.

Here is a fact about the construction industry that sounds like a joke but is not: a large share of the buildings going up around you are increasingly not built on site at all. They are manufactured - in factories, in modules, in panels - and then trucked to a lot and stacked or bolted together. This is called offsite construction, and its whole promise is that a factory is better at making things than a muddy lot is. Faster. Less wasted material. Cheaper, at least in theory.

The theory has a hole in it, and the hole is data. A factory that makes cars knows, to the second, what every station is doing. A factory that makes apartment modules has, historically, known this through a spreadsheet that a foreman updates at lunch, if he remembers, and a clipboard that goes home in someone's truck. When the module is late, or the wrong panel ships, or a quality issue surfaces three states away at the job site, nobody can say exactly where it went wrong, because the record of what happened was a shared Excel file that four people were editing at once.

Offsight is a company built entirely around that hole. Its founders, Vikas Murali and Andrew Xue, met studying engineering at the University of Pennsylvania and spent years as consultants to some of the largest engineered-to-order manufacturers in the world. Starting around 2014, they kept implementing software for their own clients in prefab and design-for-manufacturing - and kept watching the same failure repeat. The tools weren't built for a factory that makes buildings. So eventually they stopped consulting and started building the tool themselves.

What they built is, on paper, unglamorous: a mobile-first platform where a shop-floor operator taps through production steps, snaps a photo for quality control, logs materials and labor, and the whole thing rolls up - live - into dashboards a project manager and a CEO can both read. That's it. That's the product. The reason it matters is that the alternative it replaces is the single most dangerous tool in the building: a spreadsheet everyone trusts and no one can audit.

The insight worth sitting with is that Offsight is not really competing with the famous construction-software names. Procore, the giant of the category, is built for the job site - the field, the trailer, the general contractor coordinating trades. Offsight is built for the factory, the station, the unit moving down the line. It's the difference between software for assembling a building and software for manufacturing one. As offsite construction eats a bigger share of how the world builds, that distinction stops being academic and starts being a market.
