We build and run vertical software.
Hardingstone is a holding company for vertical SaaS, the niche tools a single industry runs on. We build them with what our consulting practice earns, put operators inside, and hold for the long term. Over time we expect to acquire as well as build. No fund clock, no forced exit.
