Separate question: are there any new startups out there writing code primarily in Clojure?

Their content-addressing hash would seem critical, but the "combineUnordered" hash they use just adds each byte. The API is clear that this is only as good as possible, and I'm not sure I would rely on it for data used for security investigations. I suspect they'll come up with something like an arbitrary but fixed order over keys that would improve hash quality.

More generally, while I can maybe understand what they're doing, it's hard to imagine how to QA it in a way that's convincing to customers without a lot of data/compute/coverage analysis.

There are quite a few! We do at Doccla (and we’re hiring :) (EU))

I don't know about startups, but I know of several more mature companies that are using it. It's, IMO, the best way to use the Java ecosystem.

Yes, in fact there is also a good number of conferences, for instance in less than two days https://2024.heartofclojure.eu/ starts in Belgium for instance (meet me there ;-) ).

We are writing a trading system for a small broker company in Clojure/ ClojureScript with a Datomic centered backend. The previous company some of us on the team worked at had the code-base also in Clojure/ ClojureScript.

Even if you never push the code to production, it’s a crazy gorse multiplier for the explore and adventure prototype phase of a project

"gorse multiplier" wins today's "best transcription error" award, IMO
