The Problem

Your kitchen remodel has five contractors who've never met each other.

Right now, you're the project manager — coordinating everyone through scattered texts, buried emails, and phone calls nobody returns. Cabinets finish but nobody tells the countertop fabricator. The plumber shows up but the sink hasn't been selected. Three months of takeout dinners, and you still can't answer the question: when will this be done?

Why We Built This

In construction, everything starts on the slab. It's the foundation every trade shares — the common ground where all the work happens.

OnSlab was born in the countertop industry, where we watched the same story play out on every kitchen remodel. The work was good. The trades were skilled. But five contractors on one project, with no shared view of the timeline, the selections, or each other? That's where things fell apart. Not because of bad craftsmanship — because of bad coordination. We built the tool that should have been there all along.
