... at Hack3 2021

Hack3 2021 was a blast. With hundreds of participants, 30+ industry professionals mentoring and judging, and 10+ workshops, participants experienced a truly amazing weekend. Our average participant surveys show 8.8/10 in overall satisfaction. This year, with numerous lessons learned, live judging, and backing from top tech companies Hack3 will be even better than before.

Our mission is to empower every high school student, regardless of socioeconomic status, build the change they want to see using technology.

Hack3 is a global online hackathon that aims to enable high school students to learn computer science, with a broader message of "everyone can code" targeting underrepresented demographics to improve diversity and inclusion of individuals in the computer technology space.

COVID-19’s effects have revealed great wealth inequalities in America’s communities. More than ever, marginalized and impoverished communities need opportunities to lift themselves out of poverty.

At Hack3, we believe that providing educational opportunities to learn computer science, one of the highest paying job sectors, is the solution.

We hope that by bringing students of all backgrounds together, we will be able to foster innovation, creativity, and create new lifelong friendships for hackers.

In 2021, we connected nearly three hundred fifty students of all skill levels, to build novel projects that positively impacted the world. Over one hundred attended our free classes led by industry professionals to learn new skills. Over twenty mentors lurked in our helpdesk to help participants when they needed help. Last year, our judges, mentors, and workshop instructors were affiliated with the likes of Stanford, Harvard, Amazon, NetApp, and Wikipedia.

With the lessons learned from 2021, we aim to host a competition consisting of over 350 participants, while targeting the underprivileged communities around the world. To help achieve our goal of providing a learning opportunity for everyone, we will be sponsoring internet access to those who need it to truly level the playing field for all.
