I led the product design for the service renewal of Astream, Japan’s first SNS marketing tool leveraging psychographic analysis. The goal was to transform the service into a streamlined platform where users could efficiently identify the best influencers for strategic marketing.

Astream manages over 2 million account profiles from platforms like Instagram, YouTube, TikTok, and X. The challenge was to organize this vast amount of data into an intuitive system that helps users discover influencers efficiently.

Hypothesis

• Simplified and strategic search pathways would help users navigate large datasets and select optimal influencers.

• Redefining key features and presenting data clearly would enhance user engagement and decision-making.

• Iterative UX improvements would lead to a more seamless and effective user journey.

Redefining Search Priorities
I reorganized search priorities and key features to ensure a logical flow that connects users’ actions from influencer search to performance measurement.

Intuitive UI Design
I developed a clear and user-friendly interface that simplified the presentation of complex data, making influencer selection intuitive.

Iterative UX Testing
Through multiple rounds of user testing, I continuously refined the designs to improve the overall experience and ensure the system met user needs effectively.
