About

SubVysion builds centimeter-accurate 3D maps of underground utilities so construction contractors can excavate without striking buried infrastructure. The company positions itself as 'mapping intelligence for hidden infrastructure', combining subsurface sensing with 3D mapping and augmented-reality visualization of what lies below a dig site. It was founded in 2026 by two University of Pennsylvania engineers, Maxwell Stone (CEO) and Wenson Tang (COO), and joined Y Combinator's Summer 2026 batch. Underground utility strikes are the problem it targets, estimated to cause roughly $30B in damages and 20 deaths a year in the US.

Centimeter-accurate subsurface maps delivered as an AR view of the dig site, rather than the flat 2D utility markouts contractors work from today.
