Planet Money just did a podcast on Pigeon.ly.

Fascinating to listen to the founder talking about the difficulty of starting a business as a former convict. Its ironic that because he was in prison he best understands the target market, however being in prison meant banks and other investors viewed him and his business negatively.
(edit: Planet Money did the podcast on Pigeon.ly, not another company)
