David of Lakeview Church has a nice post with his initial impressions of HelpSpot. I love these types of posts, you can really learn a lot about your product and the marketplace if you pay attention.
One of the most surprising markets HelpSpot does well in is churches and other religious organizations. I have to admit I never realized how much IT infrastructure is involved in these organizations. Somehow HelpSpot has really hit the mark in this market because we get a lot of sales there.
