Interesting that in LDS culture this isn't something that needed. Glad though there is something for seniors.

We’re all getting old. By 2060, the US population over age 65 will be about 98m. That’s about twice what it is now.
With so many people aging comes a major question: How and where are we going to live comfortable lives?
Wendi Burkhardt used to say her dream retirement would be owning a house and sharing it with all her friends. Then she decided to start a company to make it happen.
Making the golden years less lonely
Burkhardt’s company, Silvernest, is one of many startups that uses the sharing economy to increase connectivity and reduce social isolation among retirees. The company uses a proprietary algorithm to help retirees find roommates and live like the 2040 version of “Friends.”
Another startup, Papa, connects college-aged people with seniors to help them with errands and provide companionship. Reddit co-founder Alexis Ohanian’s Initialized Capital has invested millions in the “age tech” space.
Odd couple pairings
Burkhardt says women around 65 are the most common homeowners on Silvernest. But about 20% of the pairings are intergenerational.
That includes the time a 59-year-old woman started living with a 31-year-old ex-Marine man for 18 months.
“That is not what she was expecting,” Burkhardt says. “It ended up being a great success.”
