About Us
A more accessible and dynamic way to advertise where marketers, businesses, and customers win.
What if you could move the $167B+ online ad industry to the real world?
During the COVID-19 lockdowns, that’s exactly the question we set out to answer. 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.
Focus
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.
