Absolutely yes, all over the place! Startups are building greenfield software with Rails as we speak. Loads of established businesses have Ruby applications that are quietly chugging along doing their jobs well. & Shopify, a company with $1.6 billion in annual revenue, uses Ruby _very_ heavily & also invests in the wider Ruby ecosystem.

Ruby is not without its drawbacks & drama, but it’s elegant in a way that few languages are to this day (how many JS programmers _actually_ grok prototype-based object-orientation?) & compared to NPM, RubyGems is (lately) unexciting in the best way.
