Meet the team.

What if you could move the $167B+ online ad industry to the real world?

We built OneScreen to connect marketers with their ideal customers, but also small businesses with new revenue streams and consumers with content they actually want. Our mission is to enable any screen in any business to become the one screen that connects a content creator with their ideal audience.


Our Values

Solve for the customer

Creating value—for brands, screen hosts, and consumers—is why we exist. When they succeed, we succeed (and we love winning).

Do well by
doing good

We believe the technologies that will survive tomorrow are the ones taking a transparent human approach to pricing, privacy, and data today.

Work together

Our definition of “teamwork” goes beyond our immediate team. We believe in building an open ecosystem that any company can use to grow.


Tackling one thing at a time is the fastest path to success. But if we hear Sam say, “he who chases two rabbits catches neither,” we’re feeding him to said rabbits.
