As someone that is sitting in with max on meetings with business partners I have nothing but good things to say about him.
We actually recently had a discussion on how you quantify results of these meetings and how to show the community their value. Obviously you can't sit in on the meetings and it wouldn't make sense to give anyone person the credit for getting a partner company to sign on.
No matter what metrics you use, here is what I personally have seen:
Great speaking ability
Informed about the product
Very solid work on
http://bitshares.tv/ Great work done on Press kit
The book

He is one one those figures that acts as a social glue bringing devs,marketers and talkers like myself together helping us form one great simply message and then conveying that message to partners that will in turn help Bitshares become a standout among 2.0 technologies.
All that being said I can't wait to hear about his incentives and how many delegates he is asking for.
