A team of up to 12 people can function effectively, but hiring a 13th person often splits the team into subgroups, which can hinder communication and efficiency. When your team grows from 12 to 30 people, it becomes too big to be small and too small to be big, leading to awkward dynamics. The business thrives with a team of 30 to 150 people, where you can establish a strong executive team and achieve significant revenue.
