Fake fired Twitter worker ‘Rahul Ligma’ is a real engineer with an AI data startup used by Harvard

Elon Musk's purchase of Twitter (now X) sparked buzz when a laid-off engineer, Rahul Sonwalkar, played a fake FTX worker named "Rahul Ligma" before launching his AI startup, Julius. The tool, which has attracted over 2 million users, is now being used in Harvard Business School's mandatory data science course, while Sonwalkar raised a seed round with Bessemer Ventures but declined to discuss details.
