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
