An analysis of personnel is an incomplete and non-definitive answer but ought to be a useful starting point.
Paradigm Academy does not list its team on its website. However, a quick search on Linkedin yields 16 results (13 with public profiles) for people at Paradigm Academy. Of these 13 profiles, 7 include experience at Leverage Research or allied organizations, and a further 4 are well-known to have worked for Leverage Research. Edit: at the request of Julia Wise, I've encoded the names in rot13, so that this comment doesn't broadcast their association to LR to everyone who Googles their names.

Edit, June 2022: I should hope it goes without saying, but please don't harass these folks for having worked at LR.
Just saw this. The complaint was apparently that people were listed as having worked for orgs (other than LR) where they only contracted or consulted. But as I recall it, I transcribed these associations directly from Linkedin. So I've reverted the comment, and changed "worked at" to "had experience at" to more precisely match the language of LinkedIn.
