Take your business to the next level with NXG International

Built Differently

From the beginning, NXG was built for multi-engine growth. Through careful planning and forward thinking, we built our software to support multi-currency and foreign bank accounts, built multi-lingual management teams, set up satellite offices, and customized technology to further our global expansion.


Just like a multi-engine jet vs. a single engine airplane, you must build the plane from the ground up to be able to withstand the added pressure, power, and speed. NXG has done just that:

  1. North America (sales and operations)
  2. Europe (sales and operations)
  3. Latin America (sales and operations)
  4. Fidano (software and technology)

All Other MSPs

Most MSPs only have one growth strategy – US domestic sales – NXG has built a company structure designed to withstand future growth, market uncertainty, and future disruptive technologies with our four core company entities (and growing).
