Most companies know they need to move faster on AI. The problem isn't awareness — it's activation. Teams sit through presentations, attend webinars, read the reports. And then go back to doing things the same way.
An AI buildathon changes that. Not by adding more information, but by forcing action.
What Is an AI Buildathon?
An AI buildathon is a structured, time-boxed event where a team builds working AI-powered tools in one or two days. Every participant ships something real. Not a slide deck. Not a proof-of-concept that lives on someone's laptop. An actual working prototype.
The format comes from the software world — hackathons have been a staple of developer culture for decades. But an AI buildathon is different in a few important ways:
- It's designed for organizations, not just developers. Marketing teams, ops teams, HR — non-technical people build too.
- The goal is practical adoption, not invention. You're building tools for problems you already have.
- It's facilitated. There's coaching, structure, and technical support throughout the day.
What Do People Build?
In a single buildathon day, we've seen teams ship:
- AI assistants that answer customer service questions using company documentation
- Automated content pipelines that turn a brief into social posts, images, and a blog draft
- Internal tools that summarize meetings, flag action items, and route them to the right person
- Custom chatbots trained on product catalogs for sales teams
- Workflow automations that cut repetitive data entry by 80%
The tools aren't perfect. They're not supposed to be. They're working prototypes that prove what's possible — and in most cases, they become part of the actual workflow within weeks.
How a Purple Horizons Buildathon Works
We run buildathons as a full-day or two-day facilitated sprint. Here's the format:
Morning: We open with a 90-minute orientation — a quick primer on the AI tools available, examples of what other teams have built, and a framework for scoping an achievable project in one day.
Midday: Teams work. Coaches rotate through the room. We handle the technical blockers so participants focus on the problem they're solving.
Afternoon: Teams present what they built. Everyone gets a credential. We document what shipped.
After: Purple Horizons provides a 30-day check-in to help teams take their prototype into production.
The whole thing is designed around one principle: no one leaves empty-handed.
Who Is It For?
Buildathons work best for:
- Organizations that are stuck in the 'exploring AI' phase and need to move to building
- Teams that have tried AI tools but haven't embedded them into workflows
- Leadership teams that want to see AI potential demonstrated in their own context
- Companies running innovation days, offsite events, or team summits
We've run buildathons for the Miami Marlins, the Mark Cuban Foundation AI Bootcamp at Northeastern University Miami, and organizations across healthcare, finance, and professional services.
Frequently Asked Questions
Do participants need to know how to code? No. Modern AI tools like ChatGPT, Claude, Zapier, and no-code platforms let non-technical people build real tools. We tailor the format to your team's skill level.
How many people can participate in a buildathon? We run buildathons from 10 to 200+ participants. Larger groups are split into facilitated teams.
What do participants need to bring? A laptop and a problem they want to solve. We handle everything else.
How much does an AI buildathon cost? Purple Horizons buildathons start from $5,000. Pricing varies based on team size, duration, and customization.
Can a buildathon be run virtually? Yes. We run both in-person and virtual buildathons. In-person tends to produce better energy and outcomes, but the format works remotely too.
How is a buildathon different from AI training? AI training builds knowledge and skills. A buildathon produces output. The two work well together — training first, then a buildathon to put the skills to work.
Where does Purple Horizons run buildathons? We're based in Miami, Florida, and run buildathons globally. Recent events have been held in Miami, New York, and virtually for distributed teams.
