Moreover, plenty of things made for rich people stay as solutions for rich people. And some are only valuable because they are priced so only rich people can have them. Note the entire luxury goods market, for example. You could look at houses and cars as well: because those markets focus a lot of their product development on rich people, the non-rich end up with hand-me-downs that don't suit them very well.

Something else? I suppose a house should be designed so that it could easily be split into apartment units? It doesn't seem impossible to get wealthy people to consider these things, similar to how they consider the effect of the products they buy on the people in the supply chain and on the environment, but it would require a lot of research and marketing.
On the other hand, long-term planning like this is hard to do effectively. It seems like a lot of charity efforts specifically targeting the poor turn out not to be very cost effective, compared to the best approaches highlighted in GiveWell. It's hard to be confident that your average startup would achieve anything more than just showing good intentions.
I agree that do-goodery is hard. Of course, so is producing value in a for-profit context; I'm not sure which is relatively harder.
