Here’s a longer list: https://github.com/erkmos/haskell-companies https://github.com/erkmos/haskell-companies Our backend at Lumi (W15) is all Haskell. We’ve been happily building with Haskell since 2016. Lumi is making the world’s factories accessible online. The transactions that occur on Lumi are large and typically non-returnable because all of the products being manufactured are custom, mass-produced items. Haskell helps us in all kinds of ways, including performing safer migrations, and creating DSLs to define specifications of manufacturable products. https://www.lumi.com https://www.lumi.com
