51WORLD, officially known as Beijing 51WORLD Digital Twin Technology Co., Ltd., is a technology company driven by its vision of “2030 Earth Clone Vision”. Based on its core technology “digital twin”, 51WORLD has so far launched three major products:
51Aes (Digital Twin Platform) provides one-stop digital twin solutions for industries such as cities, parks, water conservation, water management, industry, energy, etc., helping enterprises enhance operational efficiency and resource effectiveness.
51Sim（Synthetic Data & Simulation Platform）generates large-scale, high-quality datasets and closed-loop simulations to bring AI into the physical world in a safe and efficient way.
51Earth (Digital Earth Platform) forging spatial intelligence tools and applications, enabling users to access the digital world in a more immersive and intelligent way.
The three major platforms are widely used by more than 1,000 large and medium-sized global enterprises, with business covering 19 countries and regions.
