Start a home health documentation review service before building the product

If you want to build a compliance tool for home health agencies, Greg Isenberg recommends starting as a service, not a software product. Find five small home health agencies and offer to review a batch of their clinical notes. Use AI behind the scenes with local models, but inspect everything manually yourself first. As you work through the notes, write down the 20 issues that keep showing up. Those recurring issues become your checklist, and that checklist eventually becomes the product. The core wedge is simple: you're catching documentation problems before they cost the agency time or money during billing, audits, or supervisor reviews. The buyer cares about fewer documentation problems — solve that, and you have their attention.
