Sothis Telecom

What Sothis Telecom does

Sothis Telecom is a Brazilian telecommunications provider, incorporated in 2009 as Sothis Tecnologia e Serviços de Telecomunicações LTDA and headquartered in São Paulo. The company holds an ANATEL license to operate as a voice and data operator (under SCM and STFC frameworks) and delivers IP-based services over its own fiber optic network. Its core product portfolio consists of PABX na Nuvem (cloud-based virtual PBX), Link Dedicado (business-grade dedicated internet with fixed IP), Banda Larga Empresarial (business broadband), and Banda Larga Residencial (residential fiber broadband), with ancillary offerings including PABX IP Local and Fibra Apagada (dark fiber) for clients requiring on-premises or infrastructure-layer solutions.

Sothis serves two primary segments: business customers (SMB through large enterprise) requiring professional telephony and reliable internet connectivity, and residential heavy-user households. It monetizes exclusively through recurring subscriptions on each service line. Distribution is executed through direct sales via website contact forms and inbound phone lines, complemented by a structured channel partner program (Canal de Vendas) that recruits and trains resellers with telecom/IT expertise. The company also operates a customer-facing mobile application on iOS and Android for self-service account management.

The company is privately held with no disclosed institutional investors or funding rounds, and operates from offices in São Paulo (two locations), São Bernardo do Campo, and Miami. It reports coverage across 23 Brazilian states plus the Federal District, with active services in 40+ cities. Its scale is modest (11-50 employees) and there are no named enterprise customers, published financials, or external validation signals such as awards or third-party benchmarks in the available data.
