Online personal finance product, Mint, has redesigned its website based on user testing. According to TechCrunch:

… Mint has been bucket testing various redesign formats with some users and is seeing conversion rates increase by 20% over the current site. … That equals “hundreds of thousands” of more registered users over the course of a year given their current growth rates..

This is a perfect example of the concepts and methods discussed in my last article discussing balancing Business vs. User needs. In this case, Mint not only figured out what its users want, but also measured how those wants would affect their business.
