Sorry for being populist. Design is created for a purpose. If your goal is to ”take over the web”, a design that appeals only to a small minority means your design failed.

Also, Figma's website looks pretty normal. It's barely registering in the scale of “neobrutalim”, whatever the hell that's even supposed to mean for a digital media.

Except there’s not much “neubrutalism” in Figma’s design. Some borders are thicker than usual, that’s about the extent of it; it’s otherwise quite similar to every other landing page. (Yes, it uses a lot of soft shadow.) Looks like OP tried really hard to find examples for something that’s allegedly taking over the web.
