I recall reading about Yesware when they started up a few years ago.  SaaS, Sales process improvement, lots of good things.  I did not follow progress of the company and did not even take a freemium version (I use Base CRM and believe them to be the best at what they do.  Their mobile app is awesome).  But I thought this summary of Yesware and their business model in the NYT was great.

PS – Hire a dedicated VP of Sales
