>We've spent millions of dollars ... so you don't have to.
This two person company that's had, from what I can tell, a hand full of clients, has spent millions of dollars testing their marketing? I find that a little hard to believe.
That said, their Playbook page is pretty cool and informative, even if seemingly most of it is behind a paywall. It'd be nice to have more information about how these ROIs were calculated. If it's a sample size of three it doesn't mean much. Or whether it was done in combination with other things, and how long those results were measured for also matters a lot. As it stands right now it just sort of comes across as marketing bullshit because it's impossible to tell how meaningful the ROIs are.
The case studies are also pretty weak. Your solution is two sentences? Really?
