The "seeking co-founder" types I was referring to are folks looking for a technical co-founder who they can partner with. They don't want a service provider, and many of them don't want to pay you cash, or can't pay you cash. Instead, they offer to compensate you with equity or revenue share.
I asked because I have partnered in part-time with a "seeking co-founder" folk few years ago ... I think I took it because I wasn't experienced neither.
It's not great. But turns out okay. It did become a passive income. (I know it's very rare to happen.)
I met with a "seeking technical cofounder" who's initial position was 'my idea is so amazing that they will be very lucky to get to be involved, they wet surprised when I said they will likely struggle to find one. What helped the most when I reframed it as 'the programmer has limited capacity and your asking them to work for free for you for a year'. He saw it didn't seem like such a good deal when put that way.
