ZeMarmot team talk at GUADEC dated 2016-08-14, and the team's blog report on GUADEC.
At the end they say there's no magic around funding free films, they have to slowly build a supporter base like Blender did. But they are also ambitious, like Blender. I hope someone gives them a large amount of funding at some point. They have refused offers to do a non-free film.
2016-06-30 blog post about funding they say have $16 a month from 6 contributors at Patreon and 42€ from 12 at Tipeee. As of right now, almost 2 months later, they're at $42/14 and 140€/27 respectively.
I think they're doing great work artistically and also to improving free production software (their post last month about GIMP) so I will go add my ongoing support.
