Early, while working on Keybase, I answered it here: https://github.com/keybase/keybase-issues/issues/788 https://github.com/keybase/keybase-issues/issues/788 Technically, not a lot has changed. We're still just putting our own money into it. However, we just added 3 people full-time and 1 person part-time, and so our costs have gone up. I'll admit, we only did this when we got an idea that we thought could turn Keybase into a business. In a few months we'll be launching a tangential idea - more than just a PGP key directory. This product will let you do some neat things with data backup and signed (possibly encrypted) file hosting and message spooling. It has nothing to do with email, but it requires a real PKI. I'll save the specifics for a big announcement, but the pricing model will reflect our costs with room to make money. More per gig than Dropbox and far less than Tarsnap. Should the "business" fail, we'll be back to where we were when I wrote the above answer.
