We were tired of seeing valuable clinical data sit around unused because it was too dirty to use, leading to suboptimal models and analyses, so we built Cornerstone AI

Meet the team

We are a group of data scientists and healthcare experts who, like most in our field, were spending too much time cleaning and standardizing data and too little time analyzing it. We have each built internal tooling to take steps to improve this process, but we knew the problem required dedicated time and resources to be comprehensively solved.
