Are there any platforms for stagnant projects or for seeking partners?

Hello, I've developed a web application designed for practicing cybersecurity exams, complete with questions and community support. I'm seeking potential partners who are interested in collaborating on enhancing its features, possibly incorporating AI functionality, and exploring opportunities for its expansion, growth and possibly pinch for funding.

Is there such a marketplace where i can list the project, or what would be the best possible way to look for a partner on this? or basically somebody who can share ideas to growth.
