Zurb is smart.
On the top is Zurb’s company website. On the bottom is their web app Verify. Notice any similarities? Without even looking carefully, I was able to recognize that Verify was made by Zurb just from the navigation. As opposed to developing a separate identity for their product, they reused a familiar element (the navigation) from the company site. The layouts are even similar to boot. Some may see this as lazy, but it’s actually quite smart.
+1 for @Zurb
