LibreOffice - Collabora offers paid support for larger companies and does a ton of development on the core
WINE - CodeWeavers has their own proprietary version (CrossOver) that they sell as a commercial product; oh, and Valve helps a ton too
GNOME - RedHat/IBM funds it and most things in its ecosystem for its commercial customers
