If we all had reliable people as co-founders, building companies would be a cakewalk.
Sadly, if it were easy, everyone would be a billionaire. Personally, tried to make it work with about 10 guys. Great talker-do nothinger, the guy with a new chick everytimer, the 3 IITians (Stay away from them, braindead, experts at body shopping, nothing else), the 3 friends (sigh) and the umpteen employees that are crappy-but no choice.
I guess finding people who have similar objectives will always be tough. Just have to keep trying.
