The Toshi app

Toshi is an investment app for beginners with no prior experience. It automatically invests a percentage of every cashless purchase into long-term stock investments. With three portfolio options varying in risk, Toshi makes retirement investing simple and accessible.

The core target users are: Germany based 18-45 y.o. men and women, with no prior investment experience.

Project kick-off

We joined the project when Toshi was in the seed stage, with prototype flows in place and are at the point of market validation.

Toshi's problem statement:
How can we redesign a portfolio overview which has all necessary information and is easy to understand for people who did not invest before?

Original app screens

The challenge

In a stakeholder interview, we learned that Toshi's startup was stuck at the market validation stage due to user mistrust and frustration. We hypothesized that their broad targeting approach made it difficult to identify consistent behavioral patterns, hindering the ability to address users' actual needs.

Our main challenge: How can we address the underlying emotional and psychological barriers that users faced regarding using the app, and retirement investments?

The process

We began with a comprehensive research phase aiming to discover:
• Understand the users' needs and motivations: Identifying pain points like confusion and frustration, while empathizing with users' financial fears.
• Learn best practices for independent stock investment: Gathering insights from industry standards to guide our design.

We conducted usability tests and user interviews to uncover pain points. Additionally, we interviewed a subject matter expert (SME) and performed a competitor analysis to benchmark successful financial tools.

Discovering design oportunities

We clustered insights using an affinity diagram and prioritized pain points with dot-voting. This led to creating two personas — Julia and Mateo — representing user's behavioral archetypess.

We focus on the following key pain-points:
• Finance scares me: Users felt overwhelmed by financial jargon and unclear data.
• Lack of trust: Users lacked confidence in the platform's security and reliability.
• Stressful market moments: Users were anxious about losing money, especially during market fluctuations.

Ideation to solution

In the ideation phase, we used low-fidelity sketches to explore how to present financial information in a way that aligns with user feedback and is easily digestible for beginner investors.

Validate with usability tests

We performed a second usability test session with a mid-fidelity prototype, we observed a significant shift in user behavior. Initially, users felt stressed and anxious, often exiting quickly. With the redesigned flow, users appeared noticeably calmer, more confident, and engaged, spending more time exploring their portfolios and making informed decisions.

The Solution: Simplifying overview for beginners

Our solution simplified the portfolio overview, focusing on clear insights rather than complex data, addressing pain points at both the interaction and journey levels for a smoother user experience.

The Outcome

Toshi's team integrated core insights from our research and design features into their MVP launch, including tangible goal visualizations, objective info and expert advice banners, and greater transparency about the portfolio breakdown.

Key learning

As a product designer, I learned research user needs from multiple angles —beyond qualitative insights, but also real-life usability and expanding to industry-level analysis and expertise.

I also learned that abstract pains like trust can be addressed on different product levels, offering various ways to engage users effectively.
