Zachary Cohn

Increasing the amount of awesome in the world.

Entrepreneur, product leader, consultant, community organizer, maker, civil servant.

And occasionally I jump on things.

Currently open to new opportunities in managing product and engineering teams


Zac lives in Seattle and likes to start things. Sometimes it's companies, and sometimes it's trouble.

He's sold one company, given away another, and shut down many more. He's led Product and Engineering organizations, consulted for companies and governments, organized community events, and backflipped across the world.
