As an employee of FullContact, I very much appreciate that the $7500 is special-purpose fun money. I'd otherwise just squirrel it away and feel bad about spending money on a fun vacation. Everyone else in the office feels the same, and feels valued as a human being not just a ROI.
I'm sure the end goal for FullContact is ROI. Or at least, it should be if they want to stay in business. They are making the bet that true, off-grid vacation each year will help their employees be more productive, efficient, loyal, etc, which certainly is a return on the $7,500 (+ time) investment.
