PROBr

Connecting clinical research to the people it's meant to serve.

Overview

PROBr helps researchers recruit participants for clinical studies — and brings patient advisors into the loop to keep study design ethical and representative. Researchers post studies; participants find ones that match their condition and demographics and get compensated; patient advisors review proposals before recruitment opens.

What we built

  • Three separate role-based dashboards — researcher, participant, and patient advisor

  • Proposal lifecycle with patient-advisor review before recruitment opens

  • Real-time researcher-to-participant chat; Stripe-backed compensation

  • Study matching by health condition and demographics
