We (PlanetScale) are the maintainers of Vitess.

Vitess is an open source and openly governed CNCF project

As far as I know, they’re the primary stewards for the project because the founders are the guys that made Vitess.

i believe the creators of the Vitess project originally founded Planetscale

Seems Vitess is a CNCF/Linux Foundation project?
