Redis, rhymes with this. Redis Labs, which captures the smallest sliver of the value OSS Redis provides, is valued at $2 B, with 2023 revenue of $151 M.
MongoDB, aka AWS "DocumentDB" (Microsoft/Azure Cosmos DB seems to have a different lineage). Mongo had $458 M in revenue Q4 2023 [1].
Nope, just the same API, completely unrelated codebase.
