Alex Payne Leaves Twitter For BankSimple

Walking away from Twitter wasn’t an easy decision. Working there has been a life- and career-changing experience. I’ve learned all sorts of lessons, made great friends, and worked on something that millions of people now use every day.

On BankSimple:

Imagine, for a moment, a bank that doesn’t suck.

A bank that doesn’t gouge you with fees.
A bank that doesn’t treat you like crap.
A bank that cares about design, but gets out of your way.
A bank that puts your money to work automatically.
A bank that’s building a platform for the future of personal finance.

Sounds good. Read more at his blog.
