> I get "marketplaces" are hard and there's a chicken/egg problem, but is anyone working on it? I think fly has the rest of it sorted and is clearly better. Would love to see the additional services as well.

I don't think that particular type of marketplace suffers from the chicken/egg problem, as that problem for me indicates when you must acquire two marketplace participants but it's hard to acquire one without the other.

But when it comes to integrations like this, you could easily write your own integrations as long as the platforms you try to integrate have APIs. Or contract freelancers to build those two. You don't need to have the platform owner to write the integration itself.

I guess I'd call it a "soft chicken/egg" problem rather than "hard".
