It's possible he has a legitamate claim, but in this day and age there's higher chance than not that he simply did some coding work and got creative with a contract.
why would someone give 1 percent of the company for every day it takes to finish a job? what was the incentive for cegli to work quickly? If he was smart, then he would have dragged it out to 50 days and become 100% owner.
no one would give away the majority share of their company for $1000 and a web site design.
Mark can't sell anything. Ceglia was granted a restraining order preventing the selling or reassigning of any Facebook assets, stocks, bonds that are possessed or owned by Mark until after the court date.
...And I own 70% of Microsoft...
This guy is a hack. If he was owed something through a legitimate contract, he would have gone after his money/capital years ago. It's worth investigating if it's true buy I highly doubt he's going to get anything out of it.
