Hey, I’m Ionah Nguyen
A product & business leader in San Jose, CA. For 10+ years I’ve worked where product, growth, and operations meet: in big tech, a fintech unicorn, and early-stage startups, including two I founded.

What do I help with?
I find the opportunity, build the solution, and align the people to get it done.
