About G-Sphere Engineering
Building South Sudan's future through engineering excellence, reliable procurement, and community-driven innovation since 2024.
From a Vision to Trusted Partner
G-Sphere Engineering Network & General Supply Ltd was founded in 2024 in Juba, South Sudan, born from a simple yet powerful vision: to provide world-class engineering solutions and reliable general supplies to a nation rebuilding its infrastructure.
In a market where quality and reliability were often scarce, our founders saw an opportunity to set a new standard. By combining deep technical expertise with robust procurement capabilities, G-Sphere quickly became a trusted partner for government institutions, international organizations, and private enterprises.
Today, with a team of over 50 professionals and 150+ completed projects, we continue to expand our impact across South Sudan and East Africa — driven by the same commitment to excellence that inspired our founding.
