So this company, Reedsy, contacted me when I started researching Upworks. Anyone know anything about it?

I know Upworks has a rep for being low paying, but I'm in need of gigs at the moment and will set myself a minimum hourly wage if I can get far enough through all of the pages of legal matter they have. But Reedsy contacting me had me wondering if something else was going on. Any experiences here?
