Looking at crunchbase, they've only raised funds using a kickstarter once. It seems like they're making enough to pay salaries and keep the show going. I know some of their products are not priced for profit, but the company as a whole seems to be doing well and growing. It doesn't seem like the typical overhyped SV company that only survives on VC money.

Who is funding them in this case, and why?

The consumers? Not turning a profit doesn't mean they don't get enough to pay their own wages and maybe even grow slowly.
