I have to say, when I first heard about the Marketing Sherpa I thought it was some startup touchy-feely marketing group too impressed with themselves to have a real name.Boy was I wrong!
From their website:

MarketingSherpa is a research firm specializing in tracking what works in all aspects of marketing (and what does not.)

So, we’re not an agency, consultancy or other vendor seeking your business. We’re not even available for private research — all our research is published for the entire MarketingSherpa community to benefit from. Our goal — to give marketers of the world the stats, inspiration, and instructions to improve their results.

Our name “Sherpa” refers admiringly to the Sherpas of Nepal who guide climbers up Mount Everest. Our goal is to be your friendly native guides who help make your tough climb toward great marketing results easier by handing you research on ‘what works.’

If you’re not already paying attention to the Marketing Sherpa, you should be.
