Hi – Sometime ago Roberto Dandi, Research Fellow at LUISS Guido Carli University (Rome) asked, “Who's doing consulting services using SNA?” The response was substantial. It is now being curated.
There is a public SNA wiki spreadsheet to collect these data. All are welcome to add, adjust, and comment.
Note: none of these offerings, sites or links have been checked, qualified or validated. For the moment, it is just rough data collection. Review, comment and contribute as you wish. Eventually these data will be checked and published.
