For the record, it's this exact injustice that kicked off Bayes Impact. Pyduan and I sat at dinner talking about my past life in private equity where I spent a lot of time looking at private prison companies, including JPay. There are huge barriers of entry into these markets, particularly in having close relationships with the decision makers: commissioners of the Department of Corrections.
The answer we came up with was a nonprofit that could develop strong relationships with civic institutions and be free from conflicts of interest and profit motives. This is a very poorly incentivized market, and startups will have a tough time disrupting the existing players because such perverse incentives exist. If anyone is interested in learning more, feel free to shoot me a message, and I'm happy to chat.
FYI, JPay is moving into all modes of communications and media, including email, video chats, music, etc. For families looking to keep in touch with their loved ones in jail, they are essentially the Apple in jails.
