Pi is thrilled to announce the winners of Pi Hackathon 2025! Pi’s first hackathon in the Open Network era invited developers to build and deploy meaningful Pi apps that empower Pi’s real-world utility and expand Pi’s use—enabled by Open Network’s external connectivity.
Here are the winners:
1st Place: Blind_Lounge, a privacy-first social and dating platform where people connect anonymously and reveal identities only by mutual choice.
2nd Place: Starmax, a loyalty program app that enables Pioneers to spend Pi at participating businesses and earn rewards for their engagement.
3rd Place: RUN FOR PI, a fast-paced runner game that incorporates Pi directly into its in-game economy.
Additionally, five apps received honorable mentions:
Kindrek
Workflet for Pi
PallyPay
SimpleJoy
Agora Pulse
Running from August 15th to October 15th, the hackathon received over 215 Mainnet app submissions that met the Hackathon’s Mainnet ecosystem requirements, showcasing developers’ clear motivation to build utility-oriented, production-ready apps on the Pi Mainnet. As these hackathon apps are community-built projects that continue to evolve beyond the 2-month long hackathon, some features may still be in progress and occasional bugs or limitations may appear. Each team may continue to refine their app and iterate based on user feedback.
Pioneers can check out all hackathon submissions under the hackathon2025 tab in the Mainnet section of the Ecosystem Interface in the Pi Browser.
