Guys. The LinkedIn is fake. The dude is a paid actor. Watch the vids, you'll see him reading a manuscript and not really knowing what he's talking about... Like repeatedly saying "and what not"
If it's fake, it was set up 2 years ahead of time in 2012.
https://www.youtube.com/watch?v=HeuYSqSu3zEMaybe Sapience was developed by someone else and they used Joe as a front, or maybe Joe was never his real name. But it's possible that Joe himself is the deadbeat dev who came up with big promises, pumped, dumped, and then disappeared.
Either way, the community is moving forward with Quotient and we can move forward with Sapience too.
