Colin Guilfoyle


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!
