Market-changing utility bill-optimizing app

Launched by an Italian start-up, Voltz helps users optimize utility bills by continually monitoring the market and automatically moving clients to the best available tariffs. 


Voltz is an innovative digital platform that analyzes your electricity and gas consumption, finds the contract that best suits users’ needs, and takes care of all the bureaucracy linked to the change of supplier.


Emerging operators on Italy’s utility market struggle with consumers’ fear and hesitation to trust the new entities. 

Voltz has decided to raise the vendors’ credibility by splitting the value proposition into three levels that allow for incremental gains to customers and represent different steps in the ‘Trust scale’.

Xfive guided Voltz through the whole process of building an application from scratch. The client received a fully functional MVP which features reflect their initial ideas.

  • 1x UX/UI Designer
  • 2x Ruby on Rails Developers
  • 1x Quality Assurance 
  • 1x Project Manager

The agile approach was evaluated as the best choice due to the ambitious scope and the tight deadline of the project.

  • Figma
  • Git
  • Slack
  • Zoom
  • Ruby on Rails
  • PostgreSQL
  • Heroku

4 months


Key achievements

  • The project’s technical part required creating a custom Web Application based on the Ruby in Rails framework. The framework allowed us to build the scalable MVP quickly and let users start using the application. 
  • The application covers both clients’ dashboards and the admin panel where staff can handle all users’ inquiries and easily present offers to the end-user. 
  • As a result, Voltz helps users optimize utility bills by continually monitoring the market and automatically moving clients to the best available tariffs. 

The application has a modern look and feel. It is fully responsive, has a clear content hierarchy, and is built with maximizing conversion rate in mind.

The concept has been designed to minimize the number of inputs from the user and the service can be consumed in less than 30 seconds from signup to utility upload. 

The web app is fully responsive and allows users to achieve an optimal experience with any device they use.

Xfive went the deepest by far in understanding what I was looking for. I’m delighted with the platform they’ve built, and our beta users have found the user journeys to be really easy.
