Igalia is a pretty interesting business. For context, they are a consultancy whose engineers contribute quite a bit to the various browser engines (WebKit, Blink, and Gecko; perhaps Servo too?), among other things. From Wikipedia:

    In 2019 they were the #2 committers to both the WebKit and Chromium codebases and in the top 10 contributors to Gecko/Servo. Igalia has helped the interoperability of some features across web engines; they implemented CSS Grid Layout in WebKit and Blink.
