Find French companies that look like your best customers
Find French companies that look like your best customers: give 2 to 5 customer SIRENs (?exemples=), optionally a region or departement, and get the first page of 100 active legal persons matching the profile deduced from them (NAF codes, workforce brackets, legal forms, creation dates, area), customers excluded, with the exact total. Under 50 results the profile widens one step at a time, each step stated; it is served as criteria to read the next pages.
