SENS: I know this sounds egocentric, but de Grey believes that even if not dying is not achieved, every dollar spent on these research will make people less sick, and that this is not "just for the rich" countries with government provided healthcare will (alredy are?) be pushing and paying for this because people not being sick will make the healthcare system save a lot of money:

Promotheus Research: They are fairly small, and write tools to help researchers digging into data:
