AAA studios also use Blender. FBX is most common which sort of necessitates Autodesk apps, but some of the studios are very OSS friendly.

Any known names?

Ubisoft, Epic and Embark are funding Blender. Not sure about Epic but Embark Studios do use Blender for sure. From their blog:

"Many of us at the content team at Embark use Blender daily, and our long-term ambition at the studio is to use Blender as our default program for 3D and environment art."

Ubisoft Animation studios are using Blender and there were some rumors last year that Blender is used in some capacity in game studios too. They definitely did a lot of work on making their content pipeline agnostic to the tool used. Transition will be slow but it's happening.

Although Not for games, but for movies Tangent Animation comes to mind.
