Find companies by activity, city and opening date (lista de empresas por CNAE)

Liveby Receita Federal CNPJ base

Lists active Brazilian companies by activity, city and opening date, for prospect lists and market sizing.

Give a CNAE code or words from the activity ("padaria", "restaurante", "academia"), and narrow by state, city, opening dates, size, head office only or without MEIs; you get how many active companies match and a page of them with legal and trade name, CNPJ, CNAE, opening date, size, capital and address, plus phone and e-mail for companies that are not sole proprietors. Example: gyms opened in Campinas in the last 90 days. From the Receita Federal open CNPJ base, refreshed monthly; it shows registrations, not whether the business is operating today. Free.
