About Me

About Me

Hey! I’m Jeremy Zimmer (jeremyz@ if we were colleagues). Mercurial Systems, LLC is my consulting business, which is just me.

Over more than a decade building and managing security programs, the most rewarding and impactful work I had the opportunity to do was working with startup scale projects in emerging technology to help them identify and address key security risks between initial prototype and product launch.

Rather than pursuing any kind of marketing strategy, I’m counting on my network to connect me with other Xooglers and similarly aligned teams who are building impactful technologies that benefit users, and maybe even make the world a better place to live.

Whether you are building hardware, software, services or some combinations, if you have a novel product idea that solves real problems for your customers, I’d like to help you make the safest and most secure version possible.
