ProjectX

At just 23, Rounak Adhikary from West Bengal is building the kind of thing that usually gets announced at Google I/O — a cloud operating system that runs any app on any device, pulling full desktop software through a browser with zero install. ProjectX just locked in YC (W26 batch) and calls themselves India's best student startup, which is either theboldest claim in the room or a self-fulfilling prophecy. The architecture is fascinating if it holds: cross-platform execution without device-specific builds, the whole OS abstracted to the cloud. Whether they pull it off at scale or become the next "looks great on slides" cautionary tale, watching a 23-year-old take on the entire cloud infrastructure stack is genuinely unhinged in the best way.
