Hobo Joe, respectfully, how often do you read Qs? A going concern tag isn’t something to strive for, but is incredibly common in growth (and plenty of established, perceived to be solid) companies.
I don't disagree with any doubts you have. My concern is when people bring up the $600 in cash statement without including the deferred revenue audited by the SEC.
10Q will have positives and negatives, but it's important to get the entire picture and not focus one thing (i.e. $600 cash vs the $1.5mil)
