I worked at Ambrosus full-time

Cons

Before you even consider ambrosus, go onto linkedin and contact former employees. At least 7 of them who left in the last 6 months were not paid their last 2 to 3 months salaries. The "positive" reviews on this site have been left by the management in order to try and boos up their outlook, but just ponder the fact that if there are more people complaining about the same thing, then there is no smoke without fire. No active clients (easy to see on ambnet), no real transactions (again log onto ambnet), a mythomaniac CEO still pushing his stillborn project to companies who once they do due diligence, quickly sever link with them. Only beardnecks will HODL on that project as there is no future for them, 2 years after spending money on a clone of Ethereum, still not clients to show for.
