"A Scaling Playbook for Entrepreneurs: Hiring for Growth" is a good article on the different stages of building a company and the type of people that are required at each stage to be successful. The important point in the article is that companies go through stages based on annual revenue and a different type of executive is needed for each stage. What the article does not discuss is how the CEO needs to change at each stage.
Stage 1, $0-10 million. The CEO needs to learn to trust people. In order to do this, one needs to learn to accept the smaller mistakes that don't put you out of business. Sales/traction, customer service and product development are important. In everything else mistakes are inconsequential. Also, learn to use control systems to monitor projects, deadlines and deliverables. (Capital raising is a CEO responsibility.)
Stage 2, $10-99 million. The CEO needs to learn to successfully delegate to managers. He should also be leading the development of more sophisticated KPI and reporting systems to understand the business at the level of individual managers.
Stage 3 $100+. The CEO needs to led the transition of the company to a plan driven organization. Hopefully you had some plan(s) before the company reached $100 million, but now the detailed plan is a necessity in order to communicate objectives, detail timing and properly estimate the capital required. A budget and a 3-year plan are advisable.
Note: I believe the stages based on revenue are:
$0-1 million (proof of concept)
$1-3 million (commercialization)
$3-10 million (scaling)
$10-30 million (delegating)
$30-100 million (management process)
$100-300 million (planning)
>$300 million
I used the other author's stages to match the referenced article.
