Little happening for a while but then the share price has gained 33% since the middle of last week. Likely something juicy afoot? Possibly their German PR has attracted some European business.
As I've said in another post this company comes from the same stable as dyesol, nms and coretrack(ckk), so the stable has form so to speak. This shareholder letter didn't contain anything too exciting, but they're communicating - which is always good. :)
