      Software Development Review from Claus-Peter Mueller

      We have engaged Infinum to develop an app that would digitalise our leasing process. From creating the initial offer through the necessary financing application and client identification to the final signature – all the steps required to successfully lease a vehicle or other object can be performed in-app, freeing the users of friction and having to deal with tedious paperwork. The app itself in the background has 30+ integrations, while keeping a seamless and quick to follow process on the front for our users. That application is in production and Infinum is responsible for maintaining it and further improving. After the initial development, we have additionally expanded our scope from vehicles to other equipment. They have also developed a Leasing widget, product which enables quick financing model while purchasing a vehicle online on car seller marketplace pages. At this moment, we are still in partnership with Infinum, and their engagement is mainly focused on localising the app to other countries and supporting us in our further business expansion. The work performed was done in Ruby on Rails and React technology, with support of other services.

      Web Design Review from Anonymous

      Thanks to Infinum's website refresh, the client has seen an almost 100% improvement in their website's conversion rates. The team excels at project management, using the client's own proprietary tool and also Figma very well. Their proficiency in design, delivery, and client relations stands out.

      Software Development Review from Shaun Bennie

      Co-funding’s collaboration with Smartym Pro began from discovery stage and design services for our online investor automation platform. In these initial stages Smartym demonstrated great skill and aptitude which convinced us to appoint them for the full MVP development part of the project. Smartym Pro’s team offered their vision to improve the quality of the delivered product. They met all deadlines and were keen to give great advice. It was a pleasure to work with Smartym Pro’s team.

      The Smartym Pro’s team has solid experience in development of web/mobile apps, blockchain platforms and smart contracts. We collaborate with Smartym Pro since June 2018 on 4 projects and are satisfied so far. The team is aware of cutting edge trends in emerging technologies and demonstrate willingness to contribute to the projects in an informal and creative way. And what is very important for us they tend to meet deadlines.
