VIOOH —who?

How do we say our name, well it sounds like 'view'. It's also a lot shorter than saying 'Viewed Impressions for Out Of Home'.

We are an open, independent and global marketplace for out of home. We combine data and technology to enable brand safe and measurable advertising, connecting brands to the right audience, all with full transparency.

Meet our awesome team.


Working with JCDecaux, the platform gave us the ability to run more relevant and impactful creative at exact frame location and times, using custom decisioning across time / location / live flight times / live weather. We saw a great impact in bookings through this ability to tailor our outdoor message at opportune moments.
