Can you name me a single 10k-30k people company that has their own internally built relational database? Their own internally developed document database? I've never seen this in my career.

I don't even know any 10-30k people companies that build their own search, most I've known use elastic search or lucene.

It's had to imagine that a few of these vectordb companies don't establish themselves as the standard solution, being the equivalent to MongoDB in their space. The other competent players will very likely get acquired.

Certainly these vectordb companies are in a better long term standing that the bajillion companies rushing to build products that are just calling an API endpoint at the end of the day.

please read my reply again, I was talking about AI companies (e.g. openai) are going to build their own vector database when there have a large enough team.

for your question, google built spanner (that was like 12 years ago) and leveldb when it had about 30k people. Meta/facebook forked leveldb and started building rocksdb when they had less than 30k people.

no one is saying any banking, insurance, retail companies with 30k employees should be building their own databases/search engines. They shouldn't. That is actually my main argument - those companies shouldn't get too involved for infra like that, they should just take the offerings of the big tech companies.
