I think I saw Apollo Research behind a paper that was being hyped a few months ago. The longtermist/rationalist space seems to be creating a lot of new organizations with new names because a critical mass of people hear their old names and say "effective altruism, you mean like Sam Bankman-Fried?" or "LessWrong, like that murder cult?" (which is a bit oversimplified, but a good enough heuristic for most people).
