From Era:
Haven have acquired a studio, or at the very least about half of the talent of a studio based in Montreal called Legion Labs.
I'm not sure if they've acquired the entire studio yet because so far only 8 of them have updated their LinkedIn in the last 24 hours, but it's possible the entire studio has been merged into Haven. The majority of them appear to be long term ex-Ubisoft employees so likely knew Jade Raymond.
Here is a list of the people who confirmed they have joined Haven from Legion Labs:
Edit: The CTO/Co-Founder lists his employer as Haven Studios on his Github profile, and a couple who still have Legion Labs listed in the profile have been interacting with those who joined Haven, so I'm pretty sure it's the entire team. This would bring Haven to about 100 people.
