Disrupting the FinTech Industry with a Mobile Solution

Success Story

Cutting-edge startups in the FinTech industry are already experiencing hype due to the disruptive technologies that drive them. Rubarb is part of the startup eco-system in Germany and wanted to introduce to the market a next-generation financial service mobile application. Its purpose is to blur the boundaries between wellness and savings and take the stress out of finance and investments, offering a holistic financial wellness solution accessible to everyone.

They needed a technology partner with rich mobile development and FinTech expertise that understands the technical challenges behind app development and can come up with a strategic solution to overcome them. Scalefocus took complete ownership of the project and delivered end-to-end consultancy and solutions that resulted in a feature-rich app with engaging and intuitive UX, combined with easy and quick onboarding, as well as robust data protection.

The Client

Rubarb is an exciting FinTech startup and the first player in Europe to offer ETF investments entirely for free without minimum purchase requirement. The company takes the stress out of the investment equitation, empowering people to easily save and invest without any financial knowledge. Providing fully integrated and automated solutions accessible for free – a mix of financial services, gamification, and online community building in cooperation with the largest bank in Europe. Savings are invested only in sustainable business portfolios from iShares, the largest asset manager in the world.

The Solution

Our team remained focused on the client’s main deliverables to reach the results they need. As a consultant and tech partner Scalefocus was involved in the entire solution development lifecycle – from information gathering to product delivery. We advised on the project management cycle and set delivery milestones to ensure that we could meet the aggressive deadline. We consulted the client on choosing the right technology stack and the most appropriate architecture.

Based on our rich mobile development and FinTech expertise, we performed a thorough analysis of the current trends, the existing competition in the niche,and their product offerings’ functionalities. The next step was to organize UX workshops for Rubarb’s team and outline the best practices in creating state-of-the-art mobile apps.

Together with the client’s in-house experts, our mobile development team delivered UI that was later described by the end-users as ‘golden’. Vivid graphics and illustrations enhanced the user experience to turn a prosaic subject like investing into an exciting opportunity. This is an incredibly challenging issue for an investment app as content needs to be easily digestible but also engaging to promote further engagement.

The multi-step onboarding process was simplified and created a sense of trust in new users. At every step, they can see what is happening, monitor their progress and see what’s next. The app removed the complexity of choosing individual investments, and the UX was designed to limit as much as possible the chance of misuse of even basic features, protecting users from losing money due to misunderstandings functionalities.

Main functionalities:

  • Three simple paths to savings – the app rounds up what users pay online and the digital change goes into their savings account; alternatively, users can go with a saving plan, or a one-time pay-ins
  • Three levels of risk in a user’s investments – users can choose from three investment strategies depending on their risk appetite
  • Investments are made in ETFs – with a focus on sustainable financial products that avoid unsustainable industries


The app was successfully deployed on the announced date and met Rubarb’s and their end-users’high-quality standards. We delivered elegant and intuitive UX with a simplified onboarding process, security of transactions,and personal information, as per the strict regulatory requirements of the EU. Our team took complete ownership of the project and treated it as their own, working in close collaboration with the client, which led to:
