Not exactly the same, but while our customer awards nomination period was open, I noticed one of our customers posting on LI about some cool integrations they worked on with our product to really extend capabilities. I shared that with their CSM and asked them to encourage the customer to submit a nomination. The customer was thrilled to get that email. They actually ended up being a finalist too, but it all started from that initial LI post and us saying hey we saw your post, that’s awesome.
All this to say, if people are out there posting on social media, they generally want to be noticed and I doubt would feel weirded out if you approached them person to person with an invite.
