Everything they can think of
For this movie they've got some government funding and a little bit from the private market, but they are aiming at private companies at the moment. They had some talks during last weeks when showing the movie on a festival in Texas, but nothing is known yet. It's seems very difficult to get the attention of big international business, they don't like investing money in small initiatives, so the guys only managed to get to talk with the investors working on a more local level (Invest NI being the biggest of those interested).
