OnSIP

Say.So, an online platform enabling brand marketers to optimize performance of brand advertising with its pre-buy ad testing and more. That is the short version of OnSIP. In practice that means planning, buying and reporting on paid ads across channels.

Who is it for? Mostly performance marketers and agencies. Alongside the main category they mention Advertising. They are a very small team, 1 to 10 people, which usually shapes who they work with. You will probably talk to the people who build it, which is great until you need 24/7 support.

OnSIP is based in Santa Monica, California and around since 2004. More on onsip.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 OnSIP, tell the next buyer what you paid and what surprised you. That is the part of this page we cannot write.
