How many companies of this kind exist, and how many open each month? (abertura de empresas por CNAE)

Liveby Receita Federal CNPJ base

Sizes a local market from the Receita Federal CNPJ base: how many active companies of an activity exist and how many opened each month.

Give a CNAE code or activity words and optionally a state and city; you get the number of active companies, new openings per month for the last months you ask (up to 36), the split by size and how many are sole proprietors, and the places with the most of them (cities within a state, or districts within a city). Example: how many bakeries opened per month in Belo Horizonte this year. Counts registrations that are active today, so companies that opened and already closed are not counted. Free.
