About us

Everything started when Geraldo Vieira Filho (GEMAIN’s owner and CTO) needed a tool to plan, track, monitor and make decisions for his business. Geraldo owned a construction and management company in Brazil for more than 20 years that provided services for large enterprises.
Not satisfied with the current products on the market, Geraldo started studying best practices and internationally accepted methods to apply on the development of a new system. After many years of research and development GEMAIN was created and still ongoing continuous improvement.
GEMAIN has already been used to manage over US$12bb in construction projects in many areas such as:
• Subway construction;
• Energy and transmission plants;
• Hospital and clinics;
• Retail and residential buildings;
• Petrochemical plants;
• Infrastructure projects – roads, bridges
