The two founders fought over money. Greg Meredith who was the CTO wanted more money to develop Rchain and Special K which he declared will be more advanced than blockchains. The CEO Dor Konforty did not want to give Greg more money because he felt the whole project is being scammed by their own CTO. Dor was given an impression by Greg that he already had a working solution in his Rchain technology but it was really nothing but vapor.
They also had an ICO that collected more money from the community maybe 1 or 2 weeks before the project's breakdown.
