Hey there HN – I'm Mohamed, CEO here at Posterity.
I've seen a lot of threads lately discussing how stuff can be transferred safely to significant others and spouses. A key aspect of that transfer is often timing, and the ability to only disclose information if and when necessary.
This is basically what Automations are about; web-hooks triggered in the event something happens, and which can serve as a reliable signal because we verify every death manually.
Today, it's available via IFTTT (https://ifttt.com/posterity), and we'll be launching standard HTTP web-hooks very soon as a follow up.
Hope you find this useful.
This seems like an obvious concern and I don't see it covered in your FAQ. This is not hypothetical. There are many similar (not identical) services that are no more. See SafeBeyond for one such example.
What do you say to folks who wonder about whether their lives will be longer than that of this site?
