Two-part collaboration and interview or challenge videos

I want to do a two-part collaboration where we create one video for my channel and another video for the other channel, so viewers of both channels go to each other’s channels. We can also do a podcast or interview style discussion about a contemporary issue, or create a fun challenge or game-based video to keep viewers engaged.

We will follow clear collaboration steps, using YouTube’s official “Collaborator” feature when uploading a jointly hosted video, and handling cross-promotion by adding the other creator’s channel link plus the video link in the description, I-Card, and End Screen. I will also pin a comment thanking the other creator.

I’m looking for any partner with an audience, so we can reach viewers across both channels.
