afaik SS is claiming it is profitable and it was always breaking even. There was an interview somewhere where the owner said until recent the only outside money was $30K loan from his dad (I think it was one with Alexis Ohanian).
Almost 300 employees, spending a ton on ad/marketing, and raising that much money–I can't see how they're profitable. I could be way wrong though.
