I've been hearing some good things about Yahoo Genome lately.
http://www.genomeplatform.com/
They have a self-serve platform, but I can only find a login - no register option (strictly beta invites perhaps?)
Has anybody tried this yet?
I used them as a staple partner when working at my last agency gig and can tell you they are fucking great. Only used a managed service though, not self serve. Their ability to form highly converting segments is top notch. and their reporting is really unique and informative as well.
Have you been able to get access to it Finch?
