The RG Challenge programme has been inspiring... it has been mind blowing! We became better entrepreneurs and we had the opportunity to take our business further. We met some amazing teams. We really profited from exchanging ideas and having great mentors!

Katerina Santikou, Workathlon

The RG Challenge was an amazing workshop in pitching! It was an amazing opportunity for us to collect what we had so far, structure it in a very nice way and then have our final 5-slide deck that we give to investors.

George Kaligeros & Dan Keene, Pushme

Our experience from RG Challenge was unique! What the team has done in London is beyond imagination. A few days with 50 hours of Business Modelling. Great mentors, a lot of new friends and one basic motto: Dream Big!

Athina Polina Dova & Ilias Vartholomaios, Owiwi

We came to understand, not only what we were missing but also we were very much helped into overcoming our shortfalls. The most prevalent sentiment that we received from RG Challenge was empowerment!!

Dimitris Giannakis, Synaphea
