The Agent Development Kit (ADK) Hackathon is officially wrapped. The hackathon wrapped up with over 10,400 participants from 62 countries, resulting in 477 submitted projects and over 1,500 agents built! Building on the excitement from our initial announcement, the hackathon proved to be an invaluable opportunity for developers to experiment with cutting-edge technologies and build the next generation of agents.  The hackathon focused on designing and orchestrating interactions between multiple agents using ADK to tackle complex tasks like automating processes, analyzing data, improving customer service, and generating content.  Now, let's give a massive round of applause to our outstanding winners. These teams demonstrated exceptional skill, ingenuity, and a deep understanding of ADK.  Grand Prize SalesShortcutBy Merdan Durdyyev and Sergazy NurbavliyevSalesShortcut is a comprehensive AI-powered Sales Development Representative (SDR) system built with multi-agent architecture for automated lead generation, research, proposal generation, and outreach.
