Introduction - Korea Foss Securities launched in 2013 as “Fund Online Korea,” operating a fund supermarket where anyone can easily invest in funds and compare and invest in low-fee online-only funds in one place. It is now transforming into a comprehensive financial platform where investing and spending come together.
Building a next-generation platform with enhanced non-face-to-face sales capabilities as a daily financial investment platform.
Korea POS Securities, with a renewed commitment to not just selling funds, prepared for a new leap together with Saltcake and FOSS to transform into a comprehensive financial platform that combines investment and consumption. While funds are often seen as difficult to start and complicated, the Fund Supermarket platform makes it easy for anyone to access and use funds. Saltcake conducted the project by identifying the fundamental needs of users and finding the intersection with rapidly evolving financial services.
Background
As mobile finance went mainstream, non-face-to-face convenience and tailored information became essential for investment services. A narrow, fund-centered product lineup was a barrier for Gen Z and new investors, and a way to explore vast financial data intuitively was needed. For Korea FOSS Securities, which vowed 'not just to sell funds' and aimed to become a platform where investing and spending meet, the shift to an everyday finance platform was the key task.
Solution
Rebranding from Fund Supermarket to Korea FOSS Securities, we designed a modular structure that unites products, information and transactions so users can reach the investments they want quickly. To fit a wide range of fund products and vast information onto mobile, we organized content page by page and, after thorough benchmarking, expressed product information intuitively. Mobile-specific type sizes and layouts shaped the UI, and personalized recommendations and search surface what users need first, raising convenience and conversion.
Key Features
• An integrated structure for investing and trading
• Better access through recommendations, search and tailored information
• A content system that makes financial data intuitive
• Mobile-specific typography and layout


In the fund market, exposing a wide variety of products and vast amounts of information on mobile devices is never easy. Therefore, organizing the content on each page and ensuring it is easily understandable is essential. Saltcake addressed this by conducting thorough benchmarking and communication, intuitively presenting product information and applying mobile-optimized font sizes and layouts to solve UI challenges. By using personalized product recommendations and search functions to display desired information, the platform enhanced information delivery and met users’ needs effectively.

We hope that FOSS will further specialize in the core purpose of funds and personalized services for users, becoming a turning point in the financial market.
