Peer39

Peer39 offers the largest and most scaled set of data available from any data provider on the market. In practice that means planning, buying and reporting on paid ads across channels.

It makes the most sense for performance marketers and agencies. They also list Ad Targeting, Advertising, Advertising Platforms, Content Marketing and Digital Marketing, so expect those to show up in the feature set. As a small product team themselves (11 to 50 people), they tend to serve customers of a similar scale best. You will probably talk to the people who build it, which is great until you need 24/7 support.

Peer39 is based in New York, New York and around since 2006. Their site is peer39.com.

Things worth asking about: platform coverage, attribution model, and fees as a share of spend. Ask for a trial on your own data, not a canned demo.

If you have worked with Peer39, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
