This stage is neither solo nor staffed. You have enough crew that the jobs get done and not enough structure that anything runs without you. Marketing is the first thing worth outsourcing rather than hiring for, because a first marketing hire at this size usually costs more than it returns.
Growth stalls here more often than at any other stage, and almost never because the work is bad.
