Joinville house, founded in October 2011 by three partners, now at Expert level in Fortinet's Brazilian directory.
Its own site gives the founding: October 2011, initially three partners, with steady growth since. Three people starting a channel business and reaching a vendor's top tier is a specific kind of story, and the mechanism is not mysterious: at that size every partner is also an engineer, so the certifications a tier requires are held by the owners rather than hired for.
Joinville is the other detail. Santa Catarina is an industrial state with a real manufacturing base and a technology sector that grew to serve it, which is why a partner there can build a business on operational customers without ever selling into Sao Paulo.
