Operator to operator, not a sales page

Where the tech actually helps

HIPAA-adjacent by default — wearable and digital health data drags compliance with it. SideGuy builds the operator-honest HIPAA and usability layer for small healthtech teams.
Notes worth trading — where digital health adoption is real, what the data and compliance burden actually looks like on the ground.

Ciarán, you work the part of healthtech that actually changes behavior.
If the compliance or data-usability side ever gets heavy, or a peer needs that layer, I am a text away. No agenda.
