Pi Network kicked off a major milestone this week by announcing the winners of its Hackathon 2025. The first global competition held after the launch of Open Network. The event attracted more than 215 Mainnet application submissions. This shows how quickly developers are creating real products for the growing Pi ecosystem.
Winning teams submitted apps focused on privacy, retail rewards, entertainment and social tools. Their projects also highlight how the Pi Network’s new Open Network is pushing builders to design real use cases. Additionally, the use of identity-verified users, Pi payments, and seamless on-chain connectivity.
Privacy app Blind_Lounge takes first place
Blind_Lounge won first prize for its approach to privacy in online social interaction. The app allows users to connect anonymously and reveal their identities only when they both agree. This design removes the usual pressure of sharing personal details from the start and offers a safer way to meet new people. The team also added the Pi utility to the core of the experience.

Users must pay a small Pi fee to create a profile, which reduces spam and helps keep the community real. Only KYC verified pioneers can participate, giving the app an extra layer of trust. The developers say the goal is to create a trustworthy social space where fake accounts and misinformation are much less common. For many pioneers, that alone makes it a refreshing alternative to conventional social platforms.
Loyalty app Starmax and Game Run For Pi Network take top spots
Starmax took second place with a loyalty program that connects Pi-compatible businesses and customers. Early adopters can spend Pi at participating stores and earn rewards. While merchants can design custom incentives directly within the app. The concept is supported by the Pi Network’s real-world adoption strategy. It gives small businesses a way to attract repeat customers and helps early adopters discover places where Pi already works in everyday life.
Run For Pi took third place with a fast-paced racing game that directly uses the Pi Network for gameplay improvements, competitions, and prize pools. The gameplay is simple and familiar, but the Pi-powered economy gives it a unique touch. Players can compete on leaderboards and use Pi to unlock items, creating a fun circuit that keeps participation high. The developers say the goal is to create games that encourage community participation. At the same time it gives the Pi a clear utility within entertainment applications.
Five honorable mentions expand Pi’s mainnet activity
Pi Network also recognized five additional teams: Kindrek, Workflet for Pi, PallyPay, SimpleJoy and Agora Pulse. Each app focuses on practical utility, from workplace matchmaking and collaboration to bill splitting, browser-based games, and community surveys. Consequently, with many apps now available on the Pi browser, early adopters can explore new tools, try out initial features, and provide feedback as developers refine their work. Mainnet’s strong participation and momentum show a community eager to build. Therefore, with more applications shipping each month, the Pi Network ecosystem is entering a new phase of real-world usability.
