Questions about these rankings
Why is there no fastest-growing list by city?
Autobound has no headquarters field for companies, and the city of a job is not where a company grows. Growth is shown by industry only.
Where does the employee count come from?
From data.numberOfEmployees in the weekly hiring-velocity signal. The ranking compares two batches of that same field.
