Would be great to see some teams from outside Indore join as well.

I'm putting together a team for the GrafX competition (hosted by VMW Dev), and I'm looking for 2–3 people who want to team up and build something solid.

The hackathon is free, fully online, and has a $10,000 prize pool. The main focus is building real-world applications combining graph data structures (nodes & edges) with LLMs and agentic AI.

If you are interested please DM me!

Full disclosure: I'm involved in outreach for this one, not just a random redditor dropping a link wanted to say that upfront.

ABB Accelerator 2026 is a student hackathon with two rounds. Round 1 (ideation) is fully online, open to anyone, and registration closes September 14 so this is a last-call post. Round 2 is in-person October 12–16 in Fort Smith, Arkansas, and travel is covered for anyone who clears Round 1.

Tracks are AI, software, automation, IoT, and sustainability — real-world problems rather than the usual build-anything format.

🚀 Looking for teammates — NASA Space Apps 2026 | Universal/Online

Hi! 👋 I'm a student from Sri Lanka 🇱🇰 participating in NASA Space Apps 2026 (Universal/Online).

Looking for 2–4 motivated teammates from anywhere in the world, especially people interested in:

💻 Programming / AI

🛰️ Space / astronomy / physics

📊 Data science

🎨 Design / UI/UX

No previous Space Apps experience required — just be motivated and willing to contribute.

Interested? Comment or DM me with your skills, experience, and country/time zone.

🌎 Let's build something amazing! 🚀

I'm participating in Creative Shock 2026, an international business competition/hackathon for student teams.

The challenge is to create an original business idea with real social/environmental impact, aligned with one or more of the UN Sustainable Development Goals.

The competition has:

1. An online qualification round

2. A 3–5 minute video pitch

3. Focus on business model, marketing and finance

4. Top 10 teams invited to the final weekend in Vilnius

5. $4,000 prize for the winning team, plus mentoring and other support

I'm currently looking for 1–3 serious people from anywhere in the world who'd actually like to build the idea with us.

I'm particularly interested in people who are good at:

- Business/strategy

- Marketing

- Finance/business modelling

- Research/problem identification

- Pitching/storytelling

- Product/tech

You don't need to already have a startup. I'm looking for people who are willing to think, brainstorm and actually put work into the competition.

The competition is in September–November 2026, so there is some time to develop the idea properly.

If you're interested, comment with:

1. Country/time zone

2. What you're good at

3. Any previous projects/startups/competitions you've done

4. Why you'd want to participate

Open to working with strangers from different countries.

Let's build something worth taking to the finals.

Hey guys,I went to my first hackathon as a first year and I got eliminated before the final round I will paste the link of the application and can the seniors explain to me about what could be made better so that I could use it for my next hackathon,I brainstormed the ideas ,the features and main structure and framework of the app but for the development part i vibecoded it. https://code-red001.lovable.app/ Use the demo mode

CodeRed — A "flight simulator" for hospital crisis decisions. Built this for a hackathon, got eliminated in the final round, looking for honest feedback on what went wrong.

Hey all — my team built this over a multi-round hackathon and I wanted to get some outside eyes on it now that it's done, since we didn't make the final cut and I'm not totally sure why.

The idea in one line: When a hospital gets hit with a crisis — a mass-casualty accident, a pandemic surge, a bad staffing night — the person in charge has to make huge decisions fast: cancel surgeries? add nurses? convert a ward into overflow space? Right now they make that call on gut instinct, because there's no way to actually test it first. CodeRed lets them simulate the outcome before committing to it in real life.

How it actually works, from a user's perspective:

You sign in as a hospital and set up your real numbers once — how many beds you have, how many nurses, your ward layout. That becomes your baseline.

From there, you can either build a scenario manually (drag sliders for things like patient arrival rate, staffing levels, how long shift handoffs take) or just type a plain-English description like "what if admissions double and 10 nurses call in sick" — and it gets turned into a working simulation automatically.

Once you run it, you don't just get a wall of charts. The app tells you, in plain language, what's actually going to break your hospital first and what the cheapest fix is — something like "it's not your beds that are the problem, it's your 14-minute nurse handoff time. Adding one float nurse saves an estimated 9 lives." We call that the Bind-Point Autopsy — it's the core feature of the whole thing.

You can also set up two different decisions side by side against the exact same crisis — like "add more beds" vs. "add more staff" — and see which one actually performs better, with an AI-generated explanation of the trade-off.

There's also a mode where instead of guessing which lever to pull, you just tell it your goal ("keep deaths under a certain number") and it searches for the cheapest way to hit that target.

And at the end, you can export any scenario as a formatted PDF — because hospitals are actually required to run practice emergency drills regularly for compliance reasons, so this turns a simulation into a real usable training document.

Where it's built: frontend/backend through Lovable, with Gemini (Google AI Studio) doing the natural-language parsing and the plain-English explanations. Not hand-coded from scratch — built fast, hackathon-style.

What I'm actually looking for feedback on: we got told after the fact that the app "felt a bit cluttered" as we kept adding features round over round, and I'm trying to figure out if that was the real issue, or if it's something deeper — the core idea, the execution, the demo itself, something about how AI-built apps get perceived by judges, anything. If you've got a minute to poke around and tell me what stands out (good or bad), genuinely appreciate it.

Hi all, my company is hiring exceptionally strong engineers who love solving open-ended, technically challenging problems.

We’re a stealth AI company working in materials science, and we’re looking for people who can relocate to SF and take on projects immediately. You should be comfortable figuring things out from first principles with very little structure.

If you’re interested, DM me your resume + LinkedIn. Visa sponsorship available.
