The Singapore-based enterprise software company spent years teaching large organizations to see their tangled IT systems. Its next act is teaching AI agents to diagnose the mess - and, increasingly, help clean it up.
LinkSure Network is the mobile-internet company behind WiFi Master Key (now WiFi Master, at wifi.com), a peer-to-peer app that lets people find and connect to shared Wi-Fi hotspots for free. Founded in 2013 in Shanghai by serial entrepreneur Chen Danian and later headquartered with an overseas base in Singapore, the app grew into one of the world's most-used utilities, reaching roughly 800-900 million users at its peak. LinkSure layers cloud security detection, encrypted tunnels and machine-learning risk scoring on top of the connection experience, and monetizes primarily through in-app advertising and content.
