GrapheneOS is leading Android custom rom, but it isn’t a startup and doesn’t support much hardware.
The others are LineageOS based and have weak points when it comes to security, privacy, and frequency updates.
All Android custom roms are still directly tied to Google’s software development (AOSP).
Sailfish OS (Jolla) is Linux based, but is proprietary, so not really an open platform.
So seems like Jolla is the only company really developing an independent mobile OS.
