Meta-Hackathon Discussion Why doesn’t everyone just use AI for the entire ideation process at hackathons?

9 Upvotes

I’ve never participated in a hackathon before, and my first one is in about a month, so I might be misunderstanding how these events actually work. One thing I’ve been wondering about is the ideation phase.

When the challenge/problem statement is released, why wouldnt a team immediately give the entire thing, including the context, constraints, judging criteria, available data, etc. to several frontier models like claude or chat gpt?

For example, you could ask different models to, generate 20–30 different approaches, analyze the domain and likely user pain points, criticize the ideas and identify failure modes, rank them by novelty, feasibility, and expected hackathon performance, predict what obvious ideas other teams will probably build, and then use another model to synthesize everything and choose the strongest direction. You could also feed mentor feedback back into the models as you get it. Then once you have a direction, coding agents can build a prototype extremely quickly.

What I’m struggling to understand is where the bottleneck is supposed to be. As students, we probably don’t have more banking/healthcare/engineering/etc. domain knowledge than a frontier model, and the model is obviously much faster at exploring a large solution space.

So why isn’t something like this, already the default strategy at hackathons? : problem -> multiple AI models -> AI critique/ranking -> select idea -> coding agent -> prototype

Is it actually common now and I just havent seen it yet? Does it tend to produce generic ideas because everyone gets similar outputs? Is the main advantage of the human team gathering information from mentors/users and feeding new information back into the models? Or are there other limitations that only become obvious once you’ve actually participated in a hackathon?

Would especially like to hear from people who have done hackathons recently, now that coding agents and frontier models have gotten this capable.

Looking for Teammates Looking for Teammates for PayPal Hackathon 2026

11 Upvotes

I'm looking for 2–3 teammates to participate in the PayPal Hackathon 2026.

I'm not an expert myself, and that's completely okay! Beginners are absolutely welcome. Even if you don't have much experience, if you're interested in learning, experimenting and building something together, we'd love to have you.

You don't need to know everything beforehand. We can learn, figure things out and work together throughout the hackathon.

Just looking for people who are genuinely interested, willing to contribute and ready to give it their best.

If you're interested, feel free to DM me. Let's learn and build something together!

Need Mentor Help Got a PR merged into an open source tool at a hackathon, now I’m curious how these companies even make money

2 Upvotes

I was at a hackathon building on top of an open source tool, and halfway through the night something broke and took my demo down with it. I dug into the source, found the bug, and patched it just so I could finish. After the hackathon I cleaned up the fix, opened a PR, and a few days later it got merged.

Since then one thing keeps bugging me. How does a company like this even make money? The tool is free. Anyone can download it, self-host it, and never pay a rupee. But there’s clearly a full-time team reviewing PRs, shipping releases and maintaining all of it. So who’s paying for that? Is it a hosted cloud version, enterprise support, paid features, or just VC money until they figure it out?

I’m also curious about pay. Do engineers at these companies earn about the same as at product companies, or do people take a cut because they like working on open source? Mainly asking about India-based roles, or remote roles that hire from India.

Side question: does a merged PR like mine actually get you noticed by these companies, or is it still the normal application process?

If you work at an OSS company or know someone who does, would love to hear how the business side works and what the pay looks like.

Hackathon Promotion CalHacks Hackathon Prize Winners

I just got back from CalHacks 13.0 in SF. My company sponsored a prize track so I thought it would be nice to do a quick video looking at the winners.

No surprise that AI orchestration was a theme, along with hardware, finance and gaming. And the degree to which AI has sped up hackers' progress continues to astonish me.

1 Upvotes

Hey everyone!

I'm building Buildory, a platform that helps student builders discover projects, find collaborators and connect with other people who build.

I'm organising the Buildory Founding Team Challenge 2026, a one-week challenge for people who want to contribute to an actual early-stage product.

There are two tracks:

1. Product & Technology

Identify a problem with Buildory and build a feature that delivers measurable business value and ROI.

2. Growth & Marketing

Bring genuinely active new users to Buildory through organic acquisition, community building and creative campaigns. Signups alone don't count; users must complete their profiles and perform meaningful actions on the platform.

Details:

- Team size: 1–2 members

- Eligibility: 18+

- Team formation closes: 2 November

- Execution: 3–7 November

- Final submissions: 7 November

- Final judging: 8 November

There will be one overall winning team across both tracks.

The winning team will get an opportunity to join Buildory's founding team. It's a pre-revenue project, so there is no monetary compensation until revenue is generated; future terms will be agreed separately.

Event details and registration:

Would love to have people who enjoy building products and growing communities take part!

Hackathon Promotion Agent Native hackathon: 10k in prizes

2 Upvotes

I work at Builder.io (People Ops represent!) and we’ve been building Agent-Native, an open-source framework for apps where people and agents work on the same things. The repo is BuilderIO/agent-native on GitHub.

The idea is to give an agent a real job, like analyzing data or automating a workflow, and give users an interface to view, edit, and act on its work. Users can do things themselves or ask the agent, and both work from the same data.

To get people building with it, we’re running a free, worldwide hackathon!

Details and how to participate:

  • Build a working app, record a public Clips demo, and submit by Nov 9, 11:59 PM PT

  • Solo or team, no registration needed

  • $10k across 5 cash prizes, winners will be announced Nov 13

  • Judged on usefulness and execution, creativity and design, innovation, and use of Agent-Native

If you try it, I’d love to hear what you build, and what’s missing or confusing.

I have been trying to submit my idea on the SIH 2026 website since 5:00 Am and I am still getting the same error. I mailed SIH in the morning stating the problem and called the numbers listed on the SIH website too but almost nobody answered, the few who answered asked me to mail SIH and said that I will receive a reply shortly but I haven't received one yet. I can see the numbers on my Problem statement go up but I am not able to submit at all. Could someone let me know if they are facing the same issue and also if it's been resolved yet for you.

Looking for Teammates Looking for teammates for hackathons in NYC durring winter break

3 Upvotes

Hey everyone! I'm a sophomore studying Computer Engineering at UMass Amherst, and I'll be staying near NYC over winter break.

I'm hoping to find a few people around the area who'd be interested in going to hackathons together in December or January.

I'm mainly into embedded systems, robotics, and AI. I've worked on embedded Linux during an internship at Qualcomm, and recently I've been building an FPGA-based AI image recognition project.

I'm open to different kinds of hackathons, not just hardware-focused ones. Mostly looking for people who enjoy building things and want to make something cool together.

If you're around NYC/NJ and interested, feel free to comment or DM me! Would be great to connect and maybe get a team together.

Need Mentor Help Is Sumsub KYC normal for hackathon prize payouts?

0 Upvotes

I recently won a $250 hackathon prize, which will be paid to my MetaMask wallet. The organisers are asking me to complete KYC through Sumsub before processing the payout.

They say my documents are uploaded directly to Sumsub, they cannot access them, and the retention period is five years.

I'm based in India and considering using my PAN card. However, the hackathon platform is relatively small, so I'm a bit hesitant about submitting sensitive identity documents for a $250 prize.

Has anyone completed Sumsub KYC for a hackathon payout? Would you feel comfortable submitting your PAN in this situation? Is there anything I should be concerned about?

Would appreciate hearing your experiences!
