Cristo Van Rensburg, founder of Cornerstone AI

Cristo Van Rensburg

Founder

I started my first business at 16 and I've built systems across hospitality, construction, real estate, insurance, fintech and franchise operations since. Different industries, one pattern every time: the founder had become the operating system, and the fix was never more software. It was a simpler way of working, built around how the business already ran, then enforced.

Cornerstone runs on the same kind of system I build for clients, so I feel every rough edge before they do. The name comes from my faith. Christ is the cornerstone, and that's the foundation this company stands on. Day to day it means people come first: I build the thing the person doing the job on a Tuesday will use.

Build on a solid foundation.
