Cofounded: MediaMath

Silicon Alley 100 rank: 21

Why you should care (from SA 100): MediaMath is one of the biggest demand-side platforms, and it is getting rich off the rise of real-time bid advertising.

The company now has over 100 employees, and acquired Adroit earlier this year.

Zawadzki is also an angel investor in some of the other New York companies killing it in this space, including AppNexus and AdSafe.
