There was a startup that aimed to "help people buy property together"[0], although it looks like it was dissolved in May 2018[1] (despite the web site still being up). (Side note: I wish companies that were no longer operating would shut down their websites - there used to be a mirror shop near where I live that still has a website listing its address and phone number, and is still near top results for a search for mirrors in my area, despite the shop having been shut and the building demolished nearly a decade ago.)
