Hack your way to the IBM TechXchange 2025 conference!

Are you ready to supercharge your skills, collaborate with developers from around the world, and score cash and a trip to Orlando, Florida in October?

Join us for an exciting virtual event where innovators like YOU will dive into the power of AI agents to build cutting-edge solutions that tackle real-world problems. Team up with peers and develop a proof-of-concept using IBM watsonx to show how agentic AI can take on an everyday issue in a new, creative way. The top 2 hackathon teams will win $5,000 USD and a trip to the IBM TechXchange 2025 conference where you can show off your smarts!

In this hackathon, you will use IBM watsonx to build a proof-of-concept solution to align with one out of two possible themes:

Build with agentic AI challenge
Use IBM watsonx to develop a working proof-of concept that applies agentic AI to solve a real-world, everyday problem. Identify a high-impact task or workflow and design an innovative solution featuring AI agents.

Sustainable cities and communities challenge, brought to you by Call for Code
We’re calling on you to build an innovative proof-of-concept for how agentic AI using IBM watsonx can be put to work to address an issue that falls under the United Nations Sustainable Development Goal (SDG) 11: Sustainable Cities and Communities.
