Check the list of companies using ClickHouse: https://clickhouse.com/docs/en/introduction/adopters/
I'm curious how you have this set up. Is it currently a manual process or you use social monitoring tools to help you find mentions of ClickHouse in the wild?
I was asking about how they are able to track mentions, across the web, of companies using ClickHouse. This type of info is usually listed in the tech stack section of job descriptions (and these links tend to expire once the position is filled).
