Our Story
We're Tiffany and Emily — the co-founders of Glowhopper.
We have deep experience leading product, data, and operations across healthcare, public health, and government. We’ve sat inside complex systems, worked across technical and non-technical teams, and understand the realities of delivering outcomes in constrained environments.That perspective shapes how we partner with clients — our approach is practical, collaborative, and grounded in real-world execution.
