It was mentioned in passing at Clojure/West a few months ago. I wish I remembered more...this video might have more details: [this video]

WalmartLabs - Clojure Developer. | SF | Remote (US Timezones) | 1HB VISA You can work on Clojure at quite a few companies, but rarely can you impact millions of people at such a personal level. Walmart's mobile apps are highly rated and the services we write to support them are the base of that success. We started from a small company acquisition with a single product. Today, we power a platform and a suite of products running on mobile devices and systems in retail stores. We're still a small, flat team of engineers. We work with our own tools and make our own build-or-borrow decisions. Our culture is a healthy mix of sharing and pushing each other to be better at our craft. For example, we

Amazon was specifically using Clojure for the online checkout system, and the team bragged a few years ago how the system survived black friday without a hickup. Walmart is using Clojure for their checkouts as well [this video] Boeing is using it in the onboard control systems for the 737 Max [LINK] It's not some obscure microservice that some intern wrote over the weekend, these companies are using the language for critical applications, and the feedback from these companies is positive.

That's not empirical evidence that formal methods are more effective than other approaches. It just shows that the culture at these companies is conductive to using them. Walmart [this video] and Boeing [LINK] etc use different approaches. :)
