There are a number of agencies/OPMs that are attending ASW. I figure your product might be better tailored towards traditional affiliate networks than CPA networks.
Just a quick glance at the meet market list, the following agencies/OPMs are signed up (in order of the list):
Schaaf Consulting
iMarketing Ltd
eAccountableOPM
PartnerCentric
I'd talk to the traditional networks as well (CJ, GAN, ShareASale) and see who they can recommend for an OPM (aside from their own services). Looks like I'm blind, or Linkshare doesn't have a table or booth, but I'd forget them anyway.
