Hackathon: PayPal and Bryntum

We’re excited to share that our friends at PayPal are hosting a hackathon, and both Bryntum and AG Grid are partnering with official prize categories.

Join in, build something with a Gantt chart, calendar, or scheduler in it, and win cash and swag.

Hackathon details#

PayPal is running Build What’s Next with AI + PayPal, a six-week hackathon with partners from across the dev tools world. We are hosting our own prize category.

• Submissions open: October 1, 2026
• Submission period: October 1 to November 12, 2026
• Winners announced: December 21, 2026
• Format: solo or team
• Requirements: use the PayPal API and AI in your project
• Submission requirements: public code, not a recycled project

The prizes 💰 #

Best Use of Bryntum: $1,000 each for three winners.

That’s on top of the wider pool of $60,000+ across all categories. Submissions are judged by a panel of experts from PayPal and the partner companies. Mats Bryntse (our CEO), along with others on our team, will judge the Bryntum category.

What to build#

Build an app integrating the free PayPal developer platform with Bryntum for our category. The app should be a working proof of concept with AI functionality included as a genuinely useful feature. Submit your project in a GitHub repo along with a description and a short YouTube demo video for the judges. See the hackathon page for details.

Scheduling and planning problems are everywhere once you start looking, and a payments API changes what you can build around them.

Some warm-up ideas:

• An agency delivery board where a late payment visibly blocks the next phase of work
• An equipment rental calendar that locks a slot until payment clears
• A scheduler that automatically reroutes itself the moment a payment comes in late
• A subscription renewal calendar with a built-in “chase them nicely” reminder flow
• …and whatever else you can dream up with a Gantt chart, a calendar, and a payments API
