We build a paywall, a conversion tool and front-ends that result effectively in a portal that offers Pay-Per-Newspaper-Article. Currently we have almost 200.000 active accounts in the Netherlands alone. You can find a better explanation here: https://launch.blendle.nl/ and the actual product is here: https://blendle.com.
We use Ruby, Node.js, Redis, Elasticsearch, PostgreSQL, Ansible, Sinatra, and more Ruby.
All the jobs postings are in Dutch. They can be found here: http://jobs.blendle.nl.
(Currently, Dutch is the main language in all communications. But we're willing to change our ways for the right person.)
