What is #GreHacks?

#GreHacks is a 2-day event where student teams compete to solve bespoke challenges set by businesses and organisations. Working with industry experts and mentors, you will be able to develop your problem solving, presentation and networking skills before presenting your solutions to a panel of judges on the final day. You will make friends, learn new skills, and have fun!

Each hack will give you the opportunity to solve real problems that businesses and social enterprises are facing; tap into your creativity, knowledge, and intuition to help them come up with innovative solutions.

All our hacks will be held in person this year!
