At the eighth iteration of WHACK, the Wellesley College hackathon, over 300 students from colleges throughout the U.S. Northeast will come together for 32 hours to turn their ideas into reality.

Whether you’re a seasoned developer or designer, or just starting out as a beginner, there’s something at WHACK for you.

You’ll enjoy a weekend of awesome tech, food, swag, workshops, and mini-events while learning from distinguished speakers, inspiring mentors, and peers. We consider WHACK a success if you make new connections and gain skills that will stay with you long after WHACK is over.
