Grist Mill Exchange’s team members came from positions across government and defense. We have worked through crises of all kinds and have experienced the challenges of meeting missions without access to timely data – either because acquiring the data would take too much time or because we didn’t know the data was available from commercial vendors.
Solving these problems was top of mind when we left government to form Grist Mill Exchange. We envisioned one secure source for government teams to find and acquire the commercial data they needed, when and where they needed it.
Dr. Jennifer Obernier is the CEO of Grist Mill Exchange (GME), where she leads a mission-focused team delivering faster, more flexible access to commercial data for defense and national security agencies.
