I'm with tptacek, Allen put in 2 years of sweat equity, was friends with bill gates, teed up the company and then had to take a backseat because of illness. How could cruise Possibly have raised money if half the cap-table was subscribed already. Also, typically there is like a 1 year cliff, so I am not sure how that would even be possible.
