Founders may find & cluster in such spaces, themselves. Once upon a time, an SF high-rise got the nickname 'Yscraper' for all the YCers there: https://www.sfgate.com/business/article/Justin-tv-to-get-boot-from-S-F-landlord-2599257.php https://www.sfgate.com/business/article/Justin-tv-to-get-boo... And, there have been dorm-like living spaces throughout the Bay Area often favored by founders & young transplants. See, eg: https://www.nytimes.com/2018/03/04/technology/dorm-living-grown-ups-san-francisco.html https://www.nytimes.com/2018/03/04/technology/dorm-living-gr... I'd expect YC might informally be able to point out such places, or formally invest in some with the right vision, but would not necessarily get further into managing housing themselves. And, too much density/interaction with disparate teams might at some point become counterproductive, compared to the classic "intense founders of the same entity living together to the exclusion of other distractions" model, or the rising capabilities of mostly-remote teams.
