Hacker Interstellar operates YoYo, a voice-centric social networking and entertainment application targeting emerging markets in South Asia, the Middle East, and Southeast Asia. The platform provides voice chat rooms where users socialize and play casual mini-games such as Ludo and Dominoes. YoYo supports 23 languages to serve diverse regional dialects across 29 countries. The company monetizes the app through in-app purchases of virtual currency, which users spend on virtual gifts, customization items, and subscriptions. Virtual gifts represent the primary revenue stream. Hacker Interstellar shares this revenue with streamers who host rooms and drive user engagement. The business model prioritizes high-value users to drive average revenue per paying user. Most revenue originates from users in Saudi Arabia, Egypt, India, and Indonesia. The company's growth strategy involves expansion into Latin America and East Asia using an AI-driven localization model. Hacker Interstellar is also developing AI products, including personalized voice avatars and standalone voice transcription tools. The company operates through its Hong Kong subsidiary and is seeking a Nasdaq listing.
