About the Hackathon

Build Fast. Launch Loud. is an in-person hackathon centered around AI-native building and Prompt Driven Development.

This event brings together developers, students, founders, and curious builders for a fast-paced day of creating, experimenting, and launching new ideas. Participants will work on projects that explore how AI can change the way products are designed, built, and shipped.

Rather than focusing only on traditional coding workflows, this hackathon invites participants to think at a higher level: defining product behavior, iterating quickly, and using AI tools to move from idea to working demo.

What is Prompt Driven Development?

Prompt Driven Development (PDD) is a way of building where prompts guide the behavior of the system and code becomes something that can be generated, refined, and regenerated over time.

In practice, that means participants will be encouraged to focus on:

• clear product intent,

• fast iteration,

• structured prompting,

• and building systems that are flexible, AI-native, and easy to evolve.

Whether you are deeply technical or simply excited about the future of building with AI, this hackathon is designed to be a place to experiment with new workflows and create something meaningful.

What to Expect

Participants can expect:

• an in-person day of building and collaboration,

• opportunities to explore AI-powered product development,

• support from organizers, mentors, and sponsors,

• and a final round of project presentations and demos.

Additional event details, resources, and sponsor opportunities will be shared with participants as the event approaches.

Who Should Join

This hackathon is open to people excited about building with AI, including:

• developers,
