I would be more happy if there was a stay with "Builders" alternative. I would love to live around with technically smart people who are building something on their own rather than "founders"
The main difficulties would be in ensuring expectations of hosts are clear so everyone is happy, and also IP. However, I think it's doable.
EDIT: There's also potential legal hurdles as to whether the accommodation is deemed payment for work. The whole platform would need to be extremely transparent to mitigate exploitation.
I think this gets tricky if you live and work in two different areas, so it’s probably best suited for remote work or new projects.
