Berkshire-hathaway's core competency is not digital or web-based. This is not a financial site. It is a site designed to entice entrepreneurs (its version of consumers.) Berkshire-hathaway is 44 years old and a fortune 500 company. Appfund is brand new and needs to build its brand/trust.
If you want your money to look pretty, you have it all wrong. And brands/trust are based on reputations of principals in the finance world, not on the website. Hell, I don't know why they have one in the first place...
Financial sites aren't consumer sites. You wouldn't call berkshire-hathaway sketchy, would you?
