Time to involve the founders, I'm afraid.
We've backed them, and their dream over the years and we can no longer stomach the dual affront of No Revenue AND No Announcements.
One of these must go.
If there is no revenue, THEN the board must make more announcements so that we can see what is happening. Only then can we decide whether to hold or sell or buy.
Do that, or responsible investors, (invested in the founders' dream) will help you find a board that will protect them.
TBH, you can send an email to Tony and put For Peter in the subject line. He is a decent guy. Let's now go direct to the master decision makers.
