How can customer marketing/advocacy hear from customer success which customers are being the most innovative and accomplishing the most from our technology?
When I've seen this work best was a time we got Customer Success really involved in suggested customer nominees for our annual customer awards. We offered the CSMs a free pass to our main annual conference where awards were given if their customer(s) was going to be announced as a winner at the conference.
In addition to the items above, we've been more frequently funding customer speaker travel to speak at events (our own or industry events) with us (flight, hotel room mainly).
