I was wondering exactly the same thing last night. There seem to be many innovators and disruptors in the tools for remote working space but no one in the space to help you find actual remote jobs, especially freelance gigs (Im not talking about quick jobs like those found on upwork and fiverr but serious projects)

Have you checked out https://remote.com/?

Yep, they're the one that I've seen so far. Beautifully designed.
