Pinterest sold it in 2018. The founder is Marco Arment, he's not the one who bought it back.

But yes, instapaper is still alive.

Ah, OK - I must have misread the bit about who bought it from Pinterest.

		It's me. For what it's worth I was involved with Instapaper at betaworks (after Marco sold it to betaworks), and Pinterest sold it back to me. Been 12 years with it now!
