Late to this, but they pretty much are done by two different companies. Figma is more like a front end that handles the logistics and sales for a bunch of studios and sculptors to get their hands on whatever weird pop culture things they wanna sculpt.
Link was done by a sculptor from Max Factory, a studio that was created in the 90s by one of the most renowned sculptors in the business. Max Factory shares an office and booths with Figma, and oversees/manufactures a lot of those releases, but the usual highest quality releases are all their fully in-house stuff. Max Factory's most recent notable releases include Link, Dread Samus, and Guyver I.
I'm very biased due to their long history with Guyver, but they've always been ahead of the curve with action figures, as far as I'm concerned.
