This is exactly the problem I've been sitting with for some time now. Every platform I tried to find a marketing partner on was either dead, full of bots, or just a generic co-founder matching app with no real skin in the game.

I'm actually building something about this, would love to stay in touch and share it with you when it's live. Might be exactly what you've been looking for.

In case you are interested to stay in touch, shoot me a message. (https://www.linkedin.com/in/lazarbogosavljevic/)
