ESIG Software e Consultoria was born in 2011 with the dream of transforming technology for Brazilian educational management. In a short time, the company became a national reference in software for education and public management, with contracts with several Universities, Federal Institutes and government agencies, in practically all units of the federation.

As of 2018, ESIG expanded its operations to facilitate lives with innovative solutions in the area of health, private education and people management, through the modern Quark product line through the SaaS model (Software As a Service). In 2019, this aspect gained importance in the strategy, generating a spin-off with its own operation: Quark Tecnologia.

ESIG Group is the conglomerate that brings together ESIG Software and Quark Tecnologia, with a great purpose of transforming the digitalization of education, health and people management services.
