Also of note, unlike Dropbox, Backblaze was able to release a new slightly more enterprisey product - B2 - without losing focus on the main product.
On the other hand, it does take a certain amount of 'privilege" (yes I hate that word, couldn't think of a better one) to have five founders who could afford to not take a salary for a year....
But one criticism, any time you post a link to the Backblaze blog it should come with a warning. It quickly led me down a TVTropes type rabbit hole of reading more interesting articles.....
