GV operates independently of Google (part of why the name changed officially form “Google Ventures” to GV) GitLab parters with and supports multiple clouds - e.g. GitLab announced official support for Amazon EKS, and IBM Cloud runs GitLab Core for version control.

GV isn't truly independent. Best way to describe it is that multiple companies in Alphabet have access to Google's tech stack and resource manager. In the early days, I advised against GV trying to get its funded companies to GCP because it wasn't mature enough and I wanted the startups to just be successful, not be political statements about Google's cloud.

That changed over the past few years; now I would easily recommend that startups funded by GV use Google Cloud if they wanted to.
