We were part of King's 20, a12-month equity free accelerator inside King's College London aimed to help students get their businesses off the ground. Tim is a King's College London Computer Science alumnus and we were offered to join the programme. The programme was completely free, i.e. We learned how to pitch, got free desk space, won 30k GBP in grant money funding and received mentorship. It was great, we love it!
We also took part in YC summer school last year and attended every office hour. We made some good friends from it that we are still in touch with today!
