A media buying platform built for what matters
Advertising is the fuel for growing your brand. And the open internet is the key to accelerating that growth around the world.
That’s why we created an independent media buying platform designed for the open internet. One that helps marketers reach more customers in more places, with more transparency and choice at every stage — from planning to pricing to performance.
At its best, the internet is an open marketplace of ideas, content, and commerce. And we intend on keeping it that way. Because the open internet matters.
Our Mission

We’re committed to making digital advertising better, because the future of the open internet depends on it.

And what we value helps us get there.
Trust
We believe advertising should be open and transparent. Which is why we give you a more objective view of where your media dollars are going, all in a privacy-safe buyer’s side platform.
Reach
Whether it's Connected TV, audio, out-of-home, or display, we can help you reach a billion more people than “walled garden" platforms, with more precision across every channel and device.
Growth
Your ad campaigns should grow your business. That’s why we built the world’s most powerful measurement marketplace, to help you prove your ad dollars are driving growth.
