Ship, Share, and Win: The Kotlin Multiplatform Award at Shipaton 2025

Ekaterina Petrova

There’s nothing quite like the thrill of shipping an app and turning an idea into something real that people can use. This summer, you’ve got the perfect chance to capture that feeling at RevenueCat Shipaton 2025 — a two-month global hackathon focused on launching new mobile apps (August 1 to September 30).

And for Kotlin developers, the timing couldn’t be better.

With Compose Multiplatform for iOS now stable and production-ready (more in our blog) , it’s the perfect moment to dive in. Whether you’re a seasoned pro ready to show off your skills or just curious to try Compose Multiplatform for the first time — this is your chance.

What is RevenueCat Shipaton?

The rules are simple:

• Build a brand‑new mobile app in eight weeks. 
• Integrate the RevenueCat SDK to power at least one in-app or web purchase (and of course, they have a great SDK for Kotlin Multiplatform)
• Ship it to the App Store or Google Play before the deadline.

Full details are on the official Devpost page.

🏆 Introducing the Kotlin Multiplatform Reach Award

Kotlin Multiplatform and Compose Multiplatform together give you the power to build apps for both iOS and Android from a single codebase, saving you precious time. But this isn’t just about quick prototypes.

It’s about creating something that scales. KMP isn’t a black box: you get full access to native APIs and can mix in platform-specific UI whenever needed. The app you build at Shipaton won’t hit a wall — it’s a solid foundation for your next big thing.

We’re excited to see what teams can create with that kind of power, and how they’ll bring their ideas to life across platforms. As Gold Sponsors of Shipaton, we wanted to introduce a category that celebrates not just technical skill, but also the spirit of sharing that makes the Kotlin community so special.

🏆 The Kotlin Multiplatform Reach Award

For the team that ships the best, uncompromising app on both iOS and Android with Kotlin and Compose Multiplatform. Bonus points will be awarded for teams that also share their development journey with the community.

This award comes with a $55,000 prize pool, distributed among the top five teams:

• 1st Place: $20,000
• 2nd Place: $15,000
• 3rd Place: $10,000
• 4th Place: $5,000
• 5th Place: $5,000

To be eligible (on top of the main Shipaton rules), your submission should include:

• A short description of your experience building with Kotlin and Compose Multiplatform. We suggest answering questions like:
  • What was your biggest “aha!” moment or favorite time-saver?
  • What surprised you most about the development process?
  • What was the biggest challenge you overcame?
• OR, for bonus points, a link to your public “development story.” This can be a blog post, X/Twitter thread, LinkedIn article, video, or any other format you prefer.

🪄 Your Secret Weapon: Junie, the AI coding agent

To give you an extra edge, we’re launching Ship with Junie — an exclusive program for Shipaton participants. We’re looking for 20 developers who want to build their Kotlin Multiplatform project with help from Junie, the AI coding agent by JetBrains, available in IntelliJ IDEA and Android Studio.

Here’s how it works: 20 selected participants will get full access to Junie for the entire two-month hackathon. In return, we’ll ask you to share your journey publicly (via blog post, video, or social media) and give us direct, private feedback.

You’ll get a teammate who never sleeps — and a chance to share your journey with the community.
