Late to the party, but I didn't see anyone mentioning this: Shopify seems to be curiously extremely involved in sponsoring WebAssembly-related projects. It's a gold sponsor on AssemblyScript[1], it used to develop javy[2] which compiles JavaScript to WebAssembly, a member of the BytecodeAlliance[3].
I wouldn't think they sponsor LadyBird just for LibWasm[4], as that doesn't make any sense, but technically, they add that to their wasm sponsorships now.
Honestly, it looks like a really nice place to work if you like WebAssembly, I wouldn't mind a collaboration or to work with them.
