Post-Hackathon
Share your work, follow up with contacts, and turn weekend projects into career-changing portfolio pieces.
The Tree Falls in a Forest
Most teams pack up and move on after the hackathon. The ones who win careers (not just prizes) know the real work starts when the event ends.
You may think that because you have no followers or no one's looking at your page, no one will ever see this project. But you never know. It only takes one. One person seeing your LinkedIn post. One recruiter clicking your Devpost. One conversation that changes your trajectory.
Post it on LinkedIn. Share the demo video. Pin the GitHub repo. You never know who's watching: a recruiter, a founder, a future co-founder. The project that sits in a private repo helps no one, least of all you.
Within the first 4 hackathons, a LinkedIn post about a project led to an interview, which led to a first internship.
Judges, sponsors, and fellow hackers are warm contacts right now. In a week, they're strangers again. Follow up within 48 hours while the connection is fresh. A short message referencing your conversation goes further than you think.
Companies aren't just watching the winners. They're scouting for grit, teamwork, and innovative thinking.
You already have half the work done. Most people don't have long-term projects because getting started feels insurmountable. But you already started at the hackathon. Why not spend the next 6 months making it outstanding?
A proven hackathon project is the easiest starting point for a portfolio centerpiece or a real product.
The Visibility Principle
“If a tree falls in a forest and no one is around to hear it, does it make a sound?”
If a project is made but no one knows about it, was the project actually made? The project sitting in a private repo helps no one, least of all you.
The First Internship Story
After the third in-person hackathon at LA Hacks, a LinkedIn post about a RAG-style chat app caught an interviewer's eye. Turns out, the interviewer was working on the exact same thing. The interview stopped being a pitch and became two people geeking out over the same problem. A week later: first internship offer.
“We didn't win. But that weekend quietly rerouted my trajectory.”
Luck Surface Area — Share Your Work
Luck isn't random. It's a function of what you do and how many people know about it. The more you build AND share, the more opportunities find you.
“Luck surface area is directly proportional to the degree to which you do something you're passionate about combined with the total number of people to whom this is effectively communicated.”
— Jason Roberts, Luck Surface Area (L = D x T)
Where to Share
The proof: Within the first 4 hackathons, sharing projects publicly led to an interview and a first internship. After that, even without actively job searching, 2 expedited interviews + 1 direct offer arrived, plus countless hundreds of recruiting DMs on LinkedIn. All from visibility, not LeetCode. You don't do hackathons to win. You do them to network.
The 48-Hour Follow-Up
Hackathon contacts are warm right now. In a week, they're strangers. Research shows: follow up within 24-48 hours or the window closes.
- Judges who asked good questions about your project
- Sponsor reps who showed interest in your tech
- Teammates you want to hack with again
- Other participants you connected with over shared struggles

- Personalize: reference the specific conversation you had
- Add value: share the project link, demo video, or a resource they'd find useful
- One clear ask: coffee chat, feedback on the project, or future collaboration
- Keep it short: 3-5 sentences max

Mark Granovetter — Strength of Weak Ties
Casual contacts are more valuable than close friends for finding jobs. Hackathon judges, sponsors, and fellow hackers are weak ties, and weak ties open doors.
Stanford, 1973; one of the most cited sociology papers ever
Reid Hoffman — LinkedIn Co-founder
“Your network is your net worth.” Your 170 connections can reach millions of people. The best connections often happen over shared struggles, like debugging at 3AM.
Turn It Into a Long-Term Project
You already have half the work done. Most people can't start long-term projects because it feels insurmountable. But you already started at the hackathon.
A winning hackathon project is already validated: judges believed in it, it beat the competition, and you have a working prototype. Spend the next 6 months making it outstanding. Put it on your resume as the centerpiece project for future internships or jobs.
Why start from scratch when you already have something that works? Polish it, extend it, ship it.
You have a working prototype, a team, and momentum. That's more than most side projects ever get. The knowledge you gained, even from a “loss,” is rocket fuel. One hackathon spent learning vector databases didn't win anything, but that knowledge landed an internship and a full-time job.
Losing hackathons is better than winning them; the “losses” are where the real growth happens.
Seth Godin / Steve Jobs
“Real artists ship.” Don't let the project die in a private repo. Keep shipping iterations; each one makes the project more impressive and more useful.
Patrick McKenzie (patio11)
Side projects compound over time into career-changing portfolios. A Bingo Card Creator built on nights and weekends turned into a full career pivot. Hackathon projects have the same potential.
Why This Works — The Science
Post-hackathon actions aren't just 'nice to have.' They're backed by research on how careers, networks, and opportunities actually work.
“The real gap is between doing nothing and doing something. In this day and age, if your work isn't online, it doesn't exist.”
Kleon's principle: you don't have to be a genius — you just have to share what you're doing. The act of sharing is generosity, not self-promotion. Make something, talk about it, and you'll attract people who care about the same things.
— Show Your Work, 2014
“Luck surface area is directly proportional to the degree to which you do something you're passionate about combined with the total number of people to whom this is effectively communicated.”
L = D x T. Do more (build, iterate, contribute) and tell more (post, share, demo). Both dimensions grow your luck surface area. Sharing one project to 1,000 people beats building 10 projects that nobody sees.
— Jason Roberts, TechZing podcast
Mark Granovetter's landmark 1973 Stanford study found that casual contacts (people you don't see every day) are more valuable than close friends for finding jobs and opportunities. They connect you to networks outside your own circle.
Hackathon judges, sponsors, and fellow hackers are weak ties. Cultivate them. They open doors that your close friends can't.
— American Journal of Sociology, 1973
“I knew that if I failed I wouldn't regret that, but I knew the one thing I might regret is not ever having tried.”
Project yourself forward to age 80. Will you regret sharing that project publicly? Will you regret sending that follow-up email? No. You'll regret staying silent. The downside of sharing is zero. The upside is unknowable.
— Jeff Bezos, founder of Amazon
The Post-Hackathon Playbook
A step-by-step timeline for maximizing the value of every hackathon. Follow this and your projects will keep working for you long after the event ends.
Day 1 — Within 24 Hours
Send follow-up messages to judges, sponsors, and contacts you met. Pin the GitHub repo to your profile. Update your LinkedIn headline if you won a prize. The connections are warmest right now, so don't let them cool off.
Day 2-3 — Share Publicly
Write and publish a LinkedIn post about the project. Share the demo video. Tag teammates, sponsors, and the hackathon org. Tell the story of what you built, what you learned, and what's next. This is the post that gets seen.
Week 1 — Clean and Open-Source
Clean up the GitHub README with proper badges, screenshots, and install instructions. Open-source the project if possible. Add it to your portfolio site. Write a short blog post or Twitter thread about what you learned.
Month 1-6 — Keep Building
If the project has legs, keep going. Set a monthly milestone. Treat it like a real product; the hackathon gave you the MVP. Add features, get users, iterate based on feedback. This is how weekend projects become portfolio centerpieces.
“It's not enough to be good.
In order to be found, you have to be findable.”
— Austin Kleon, Show Your Work
The hackathon is the beginning, not the end. Every project you share, every follow-up you send, every iteration you ship expands your luck surface area. The person who sees your LinkedIn post might be the one who changes your trajectory.
You never know who's watching. You never know which conversation will be the one that matters. The interviewer who happened to be working on the same thing. The recruiter who stumbled across your Devpost. The founder who saw your demo video.
You never know. And that's the whole point.
Post-Hackathon Checklist
A step-by-step summary for maximizing the value of every hackathon. The event is over. Now the real work begins.
Send personalized follow-ups to judges, sponsors, and contacts within 48 hours
Write a LinkedIn post about the project and tag teammates, sponsors, and the hackathon org
Pin the GitHub repo to your profile and clean up the README
Share the demo video on social media (it's the highest-signal content you can post)
Open-source the project if possible; it becomes a living portfolio piece
If the project has potential, set monthly milestones and keep building (you already have the MVP)
"If your work isn't online, it doesn't exist": make sure everything is findable
Remember: The hackathon gave you the project, the connections, and the momentum. What you do with them after is what separates people who attend hackathons from people whose hackathons change their careers. Share it, follow up, keep building. It only takes one.
