Rob has almost single-handedly funded UCM for the past 6-8 years, mainly because few others would. I don't know where his source of capital is, but surely not from his fat CEO pay cheques.

He's been acquiring assets, developing new brands, building new markets directly and through distributors, shoring up the manufacturing supply chain to meet COGS expectations of low price markets and demonstrating the product to KOLs and hospital staff. This guy is an all singing, all dancing, inventer-entrepreneur one-man-show, all while (now) taking shares instead of money.

There's good reason for anaemic sophistocated investor interest. Is it Rob? IMO, almost definitely.
What he needs is to inject an experienced executive with experience in taking the next step in business. It's no good having products that you can't sell at volume. There is no sign of this happening yet with present executives unfortunately......
