We are using Sapiens for our online ad buying process which has been very easy to implement into our current workflow system as well have an excellent support team in place should we need additional assistance or training materials. Nothing really I would like more than less ads being served but it's not bad so far! It does seem to be doing what they say it will do. If you're looking specifically for an Online Advertising tool this one fits your needs perfectly. The only downside so far is that my colleagues aren't fond of their interface since it looks quite different from most other tools/sites available out there today (maybe its just me). But overall great product - works amazingly and helps us manage all clients campaigns within SAP CRM easily.
