As the effects of COVID-19 continue to become more and more severe, TeenHacks LI has made the ultimate decision of postponing our Spring 2020 hackathon to this fall. Though our team has worked sedulously on this event, the safety and wellbeing of our coding community is our first priority. We thank you for your support in our organization and hope you join us as TeenHacks LI continues to achieve. We apologize for any inconveniences we may have caused and we hope you and your families remain healthy in these uncertain times.

Make sure to keep a lookout for our Fall 2020 event and follow us on Instagram to stay updated on any future announcements

About Us

Calling all programmers, designers, makers and leaders! TeenHacks LI is Long Island’s premier 24-hour high school hackathon, by students, for students. Take part in group collaboration, interesting workshops, sweet prizes, and more. Get ready to meet new people and have an amazing time. Join us as we build the future!

Founded by Jeffrey Yu and Wesley Pergament, we bring together the brightest students across the tri-state area to engage in “collaborative coding.” We hope to build a hacker community here on Long Island, with an emphasis placed on innovation and entrepreneurship.


What is a hackathon?

It's a place where programmers, engineers, designers, and entrepreneurs come together to build an awesome project in 24-hours. We provide the venue and food, you bring the creativity. Get ready to learn, build something cool, and meet new people. Check out this article by Dave Fontenot to learn more! What is a Hackathon?

What if I’m a beginner?

Do not worry. TeenHacks LI encourages students of all levels to come! In addition, we will have workshops throughout the hackathon as well as mentors available to answer any of your questions.

Who can attend?

All high school students are welcome to attend. If you are older or younger and still want to participate as a hacker, shoot us an email. If you're older, we welcome you to sign-up as a mentor!

Does it cost anything?

TeenHacks LI is completely free, thanks to our generous sponsors! This will include food, swag, and awesome prizes.

What if I don't have a team?

In the beginning, we’ll have a team formation session to make sure you’re not alone. You can have teams as large or small as you want, but only teams of 2-4 will be eligible for prizes.

What should I bring?

You should bring your student ID, laptop, phone, chargers, sleeping bag, deoderant, toothbrush, as well as any hardware or materials you may need for your project. Nothing hazardous or illegal.
