Digital Nomad/Coliving - New Idea Validation

Hi all, I've been reading Aravid Kahl's books around choosing an audience and finding/validating critical problems before proposing a solution. From my experience as a digital nomad, Coliving has been one of the easiest ways to make friends and connections in a new city. But I've also lived in Colivings where I didn't vibe with the people and had a poor experience. This took me down the rabbit hole to understand how Coliving owners select and vet prospects before deciding if they're the right cultural fit. Or do they not care much and just need the rooms filled. I've been contacting Coliving owners on FB for a quick chat but having a hard time getting their attention and real insight out of the exercise. Spoke to a few digital nomads and had lukewarm responses. Inspiration for this idea came from Courtland Allen's interview (Indie Hackers) with Lynne from Key Values around how Lynne matches engineers with tech companies based on culture fit. What do you think and any feedback from experienced entrepreneurs around critical problem validation? Cheers!
