Unfortunately, in the age of the internet, just because a site says they don't take a fee, doesn't necessarily make it so... so please do excuse my skepticism.
I welcome your skepticism and critical thinking, if more people had more of it, the world would be a better place :)
Fundition earns money by two ways, donations and curation awards on steemit. Every project owner (if he or she wants) can make Fundition a Beneficiary with some percentage (usually 1% and not by all founders). When you take all this into account, we are faaaaaaar behind other platforms and their profit and proud of it.
