Process, management, de-empowerment, hiring B people.
Most of the useful work on the planet is done by B or below people.
1) You are hiring for boring but important projects
2) There is a limited pool of local talent
3) The org will have banded salary caps
4) Differentiating A talent from B players is not a solved problem
It feels great to say, "Just hire A graders! Problem solved yo!" The corporate world does not work like this.Or you can get the best people in the door on a reasonable timescale and salary, and start building and learning.
Mature companies have already made those mistakes. Startups in the early growth phase are often some of the worst places to work until they figure out how to operate at scale.
You would be surprised how many young companies fall straight into old school corporate habits as soon as they grow past 20 employees.
