You’ve registered for a hackathon. You’ve got your team. You’ve got 24 hours. Now what? The difference between teams that win and teams that just participate usually isn’t technical skill — it’s strategy.
These 15 tips come from observing 92,403 team registrations across 196 hackathons on Reskilll. This is what actually works.
Before the Hackathon
1. Build Your Team for Complementary Skills
The ideal hackathon team has 4 people with different strengths: one strong backend developer, one frontend/UI person, one AI/data person, and one who can present and handle the business case. The worst teams are 4 people who all do the same thing.
2. Set Up Your Environment Before Day One
Don’t waste the first 2 hours of a hackathon installing Node.js and configuring API keys. Before the event:
- Set up your development environment and test it works
- Get API keys ready (Gemini, GitHub, any cloud services)
- Create a shared GitHub repo with a basic project structure
- Test your deployment pipeline — can you push to production in one command?
- Download Google Antigravity or set up your preferred AI coding tool
3. Research the Problem Statements Early
Most hackathons publish problem statements before the event. Read them carefully. Research the domain. Talk to people who face the problem. The team that understands the problem best usually builds the best solution.
During the Hackathon
4. Spend the First Hour Planning, Not Coding
This is the most counterintuitive tip and the most important one. Resist the urge to start coding immediately. Spend 60 minutes on:
- Understanding the problem deeply
- Defining your solution’s core feature (ONE feature, not five)
- Sketching the architecture on paper
- Dividing work so everyone can code in parallel
- Defining what “done” looks like for the demo
5. Build the Demo First, Features Second
Judges evaluate what they see in a 5-minute demo. Work backwards from the demo: what do you need to show? Build that first. Then add features if you have time. A polished demo of one feature beats a broken demo of five features every time.
6. Use AI Coding Tools Aggressively
In 2026, not using AI coding tools in a hackathon is like not using a calculator in a math exam. Use Google Antigravity, Claude Code, or Cursor to:
- Generate boilerplate code in minutes
- Build API endpoints by describing them in natural language
- Create frontend components from descriptions
- Debug errors by pasting them into the AI
- Write tests automatically
Teams that use AI tools effectively build 3-5x faster than those that don’t. This is what vibe coding is all about.
7. Have a “Feature Freeze” 4 Hours Before Submission
Stop adding features 4 hours before the deadline. Use that time to:
- Fix bugs in existing features
- Polish the UI
- Prepare the demo and presentation
- Write a clear README
- Test the entire flow end-to-end
8. Get Mentor Help Early
Don’t wait until you’re stuck for 3 hours to ask a mentor. Talk to mentors in the first few hours to validate your approach. Through MentorVerse, Reskilll hackathons provide access to 1,389+ experienced mentors. Use them.
The Presentation
9. Tell a Story, Not a Feature List
Structure your presentation as: Problem → Why it matters → Your solution → Live demo → Impact. Don’t list features. Tell the story of a real person who has this problem and how your solution helps them.
10. Demo Live, Don’t Use Slides
Judges want to see it work. A live demo is 10x more convincing than screenshots on slides. Have a backup video recording in case something breaks, but always try the live demo first.
11. Show the AI Value Clearly
If it’s an AI hackathon, make it obvious what AI adds. Show a before/after: “Without AI, this takes 2 hours manually. With our solution, it takes 10 seconds.” If you can build it without AI, it’s not an AI project.
12. Prepare for Questions
Judges will ask about scalability, security, cost, and edge cases. Have answers ready. “We haven’t thought about that” is the worst answer. “We considered X approach but chose Y because…” shows maturity.
Mindset Tips
13. Sleep Is Not Optional
The team that pulls an all-nighter and shows up exhausted for the demo always loses to the team that slept 4-5 hours and presents with energy. Take shifts if needed, but don’t skip sleep entirely.
14. Scope Down Ruthlessly
Your initial idea is always too big. Cut it in half. Then cut it in half again. The winning project is the one that does one thing really well, not the one that tries to do everything.
15. Have Fun
The best hackathon projects come from teams that are genuinely excited about what they’re building. If you’re not having fun, you’re probably building the wrong thing. Switch ideas if needed — it’s better to pivot early than to grind through 24 hours on something you don’t care about.
Practice Makes Perfect
The best way to get good at hackathons is to do more hackathons. Reskilll has hackathons running every week — from one-day sprints to week-long challenges. Start with a small event, apply these tips, and iterate.
Tip 4 about spending the first hour planning changed everything for us. We used to start coding immediately and always ran out of time. Last hackathon we planned first and finished 2 hours early.
The AI coding tools tip is so true. Our team used Antigravity at the last Reskilll hackathon and we built 3x faster than teams coding manually. It is not cheating — it is being smart.
