Great post. I wanted to pass along the tool rapportive, which is a built-in email address validator for Gmail with social feeds. It's a killer free tool that no sales team should omit.
i'd add olark[1] & nerdydata[2] to that list as well.
I even have a SaaS product built, but yet to deploy - I'm testing the following way:
...i put a "pre-order" or "buy" via gumroad widget, and will start deploying once i have my first purchase. just stats on how many people go down the funnel[3]( clicked the "for companies" link, # who viewed price, # who clicked "i want this" is worth the 10 mins setting up your product on gumroad ...
