Pros
Some very good experienced people have been hired. The product is interesting with apparent upside. Some of the board appear to be accomplished, and some big names have invested. A good story, on paper.
Cons
Jeff as a leader is a big negative. Accomplishments have been and continue to be exaggerated, and the rate of progress too slow. Promises made appear to be rarely kept. I have seen too many accomplished senior employees come in to the company and leave after a while with their resumes damaged. The work environment is very toxic causing there to be a general negative environment most of the time. People avoid putting in extra effort or putting forward new ideas as they will be shot down by Jeff. It is confusing to me why Jeff does not allow progress to happen. Very slow decision making as a result of Jeff needing to be involved in everything.
