CoreWeave got there first, launching in 2017 — that's 6 years of extra runway. Nebius didn't arrive until 2023. In AI, that kind of head start means more training data, deeper customer relationships, and a bigger talent moat.

CoreWeave has about 1800 employees; Nebius has about 1,000. A bigger team usually means more revenue or heavier VC backing, but in AI, small teams can build at massive scale.

Yes — they're direct rivals. Both CoreWeave and Nebius compete in AI Infrastructure, targeting many of the same buyers. If you're evaluating one, you should be looking at the other.
