The Bloomathon Winners: What Builders Shipped in 6 Days
See the winning apps from the first Bloomathon, a 6-day build-in-public challenge where makers used Bloom to turn ideas into real apps.

The first Bloomathon is officially wrapped, and the results are in.
Over six days, builders used Bloom to go from idea to working app. They shared progress in public, tested ideas quickly, and shipped real products instead of pitch decks.
That was the whole point of the Bloomathon: build something people can actually try.
Now it is time to celebrate the winners, the standout projects, and a few of our favorite examples from the week.
What Was the Bloomathon?
The Bloomathon was a 6-day build-in-public sprint for founders, makers, developers, designers, and anyone with an app idea.
Participants used Bloom and GPT 5.5 to create working apps, then shared their progress on X, LinkedIn, TikTok, and Discord. Every submission was judged on four criteria:
- Functionality: Does the app work?
- Design and taste: Does it feel good to use?
- Originality: Is the idea fresh or promising?
- Bloom utilization: How far did the builder push what Bloom can do?
Unlike a traditional hackathon, the Bloomathon was not about slides, mockups, or polished pitches. It was about shipping.
Meet the Winners
1st Place: Voice-First Social App
Built by Daud
What made the project stand out was not only the concept, but the execution. Daud connected real APIs like Deepgram to power the voice and transcription layer, turning a quick idea into a working product experience. That is a big part of what Bloom makes possible. Builders can move past static prototypes and connect the services they need to make an app feel real.
Why it stood out:
- The app had a clear product idea: voice-first social posting with a simple feed.
- It used real voice and transcription infrastructure through Deepgram.
- It included synced text playback, making the audio experience easier to follow and more accessible.
- It felt like a real product direction, not just a hackathon demo.
Prize: 30,000 OpenAI credits and 3 months of Bloom Pro.
What Builders Made With Bloom
Across the Bloomathon, people built apps for productivity, education, personal tools, communities, AI workflows, and startup ideas.
Some builders came in with a clear product concept. Others started with a rough idea and used Bloom to shape it as they went.
That is one of the best parts of building with Bloom: you do not need to start with a technical spec. You can describe the user, the journey, and the feeling of the app, then iterate from there.
For example, a strong Bloom prompt might look like:
Build a mobile app for busy students who want to track assignments, deadlines, and study sessions.
Build a mobile app for busy students who want to track assignments, deadlines, and study sessions. The user should be able to add classes, create tasks, see what is due this week, and get a simple daily plan. The app should feel calm, focused, and encouraging, not overwhelming.
Bloom turns prompts like that into a working cross-platform app with native UI, backend logic, data storage, and authentication.
What We Learned
The biggest lesson from the Bloomathon was simple: people ship faster when the tools get out of the way.
Builders did not spend the week setting up a backend, configuring auth, wiring databases, or fighting boilerplate. They spent it making product decisions:
- Who is this for?
- What should the app do first?
- What does a good user journey feel like?
- What should I improve after testing?
- That is where the best building happens.
The Bloomathon also showed how useful build-in-public can be. Sharing progress helped participants get feedback, stay accountable, and make their projects easier for others to discover.
Keep Building
If you participated in the Bloomathon, thank you.
Whether you won a prize, submitted a final app, or simply made progress on an idea, you did the thing that matters most: you built.
You can keep improving your Bloomathon project, start a new app, or share what you made with the community.
And if you missed this one, stay tuned. More Bloom challenges are coming soon!
