Our experience building a business with Clojure has been amazing. It has helped us to attract extremely strong engineers, and churn has not been a concern in the slightest. We've taught people (from code beginners to experienced engineers) Clojure, and all of them are able to start adding value in a very short space of time. We're six years in and there are no signs of increased maintenance difficulty due to the language. We follow the Polylith Architecture (https://polylith.gitbook.io/polylith/), which has given us yet another boost in developer happiness, speed of delivery, and ease of maintenance. There are many extremely large Clojure code bases out there (Ladder life, Lemonade, Simply life, Wallmart, Nubank, Atlassian) not suffering from the maintainability issues that some people here have described.

After six years, I would absolutely (without hesitation) start another business with Clojure as the core.
