Are there any startups using Java (not JVM) based web stacks (not backend or API endpoints). Any comments/experiences would be welcome !
I use Rails in my company, which is not a startup anymore, but we are using java in a new venture.
Our stack in this new company is based on spring (spring-boot, spring-data-rest, etc) and angularJs. We are very happy with it. Spring security and spring-data-rest are amazing.
I love Rails with all my heart since it's what we use since 2005, but I have to say I'm impressed by the advances in Java in the last year or two. That said, if you are doing SPAs Java can be more productive than Rails.
