HueDx
HueDx is a Philadelphia diagnostics company - formerly Group K Diagnostics - that turns any smartphone camera into a reader for lab-grade, quantitative color-based tests. Its patented HueCard color-correction hardware and AI-powered HueTools/HueCloud software let researchers develop, validate, and deploy paper-based colorimetric assays without proprietary readers or lab infrastructure, aiming to make quantitative results available at the point of care and at home.
Brianna Wronko-Stevens
Brianna Wronko-Stevens is a University of Pennsylvania-trained bioengineer who turned a senior design project into HueDx (formerly Group K Diagnostics), a Philadelphia diagnostics company that reads lab-grade results off a color-changing card and a smartphone camera - no lab, no reader, no waiting days. Inspired by an HIV clinic internship at 17, she built a platform to deliver fast, quantitative results to the patients who can least afford to wait. She founded the company in 2017, served as CEO through a 2023 rebrand and raised millions in funding, then stepped into the Chief Scientific Officer seat to focus on the science.
