TowerData

TowerData makes it easy for marketers to enhance, clean and grow their email lists. The job it does: planning, buying and reporting on paid ads across channels.

The natural audience is performance marketers and agencies. Related areas on their profile: Advertising, Analytics, Email, Fraud Detection and Information Services. 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.

TowerData is based in Fairport, New York. You can read more at towerdata.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.
