Colin Guilfoyle

Managing Director

Entrepreneur who’s coded since 8 years old and for some reason best known to himself qualified as a CIMA accountant in 2009. Founded Nebula in 2014 and quickly found that games were his passion when it came to code. A big believer in giving back, Colin has spoken about giving through gaming, volunteered Nebula and himself for various good causes and does what he can to get young (and old) into games and computers. These days Colin doesn’t get to code as much but with the introduction of our robotics gaming projects has gotten to combine his 2 geek loves of computers and robots!

If he’s not in the office, Colin will likely be sitting in a cafe or making something either with a 3D printer, Lego or whatever he has to hand. That, or he’ll be chasing Pokémon with his wife around Dublin!

Aoife Rafferty

Office Manager

With a B.Sc in Marketing, Innovation & Technology, Aoife has always had a keen interest in the Irish start-up scene and participated in the UStart Student Accelerator program run by the Ryan Academy in conjunction with Dublin City University. Joining the Nebula team in February 2018, she brings years of experience in contractor management, recruitment and project coordination. Here at Nebula, she wears many hats (as do we all!) and works on all things project management, social media, events and most importantly, the day-to-day running of our studio.

When she’s not working, you can find her enjoying live music, walking her dog, spending time with family and friends or at the gym. All of the aforementioned activities are usually accompanied by pizza.
