Selected case studies

Financial technology and e-commerce both have taken a prominent scene within the London’s startup community. Railsware as a Ruby on Rails company has a deep domain knowledge and technical base for both of these worlds.

We have a bunch of projects behind the belt: from end-to-end product development to helping with existing products. Here are few key showcases of our London clients.


Create An Online Shop & Website, Bring Your Brand To Life

SupaDupa is an ecommerce solution established by 3 friends in London in 2010 to provide a platform for independent creatives, willing to promote and sell their work. Makers of any kind can create their own stores in a matter of minutes by choosing the theme, uploading photos of their products and publishing them. The key idea was to stand-out from the overly-priced, boring ready-made shop platforms.

Railsware has been a development backbone for Quorso since the very beginning. We went through all the stages of the process: made inception with all goals stated, identified risks, brainstormed the roadmap. Afterwards, the solution was carefully tested in a real world by building a 1-month POC, bigger MVP and finally moving on to the fully-functioning release. Nowadays the team is working on adding features to the existing product and building up a mobile app.

Co-Founder, Head of Product

We took a very McKinsey approach to finding Railsware. It basically meant looking at 80 agencies and having in-depth meetings or interviews with 40 of them. We met with all the major London based development companies, we went out to the US and met some agencies there, and we spoke to a large number of European agencies. At the early stage of the business it is very important to choose the right development partner and Railsware proved to be an absolutely the best choice.
