토스의 브랜드 심볼을 찾아서 (opens in new tab)

Toss, a leading Korean fintech platform, embarked on a UX research journey to define its visual identity as it expanded from digital services into offline environments like Toss Pay payment stations. The study revealed that while users strongly associate the brand with seamless "usability," they lacked a single, clear mental image of a visual symbol. By analyzing user perceptions of fonts, colors, and shapes, Toss identified a specific visual formula—combining the app icon shape with a white, blue, and black palette—to ensure the brand remains instantly recognizable in the physical world. ## The Challenge of Offline Brand Recognition * The project began with the need to design "danglers" (small signage at payment counters) to signal that Toss Pay is accepted at offline merchants. * While Toss had successfully used various logo iterations online, the team realized that "Toss-ness" learned within the app might not automatically translate to unfamiliar offline environments. * Initial internal debates focused on superficial visual tweaks, such as background colors or language choices, rather than understanding the core assets that trigger brand recognition. ## Identifying Usability as the Core Brand Image * In-depth interviews were conducted with participants selected for their ability to articulate abstract brand impressions. * Research showed that users primarily associate Toss with keywords like "clean," "practical," and "convenient," rather than specific aesthetic elements. * One participant described Toss as a "program made by a genius engineer in Excel," highlighting that the brand’s value was rooted in its utility rather than a distinct visual symbol. * This presented a challenge: since the "app experience" cannot be felt through a static offline sign, the team had to find a visual surrogate for that functional reliability. ## Deconstructing the Toss Symbol: Font, Color, and Shape * **Font:** Testing revealed that the most recognizable font was the black English "toss" wordmark, primarily because users see it most often in external media and news rather than inside the app. * **Color:** Surprisingly, users did not associate Toss with a single shade of blue. Instead, they recognized the specific combination of a "blue logo on a white background." * **Logo:** When asked to draw the logo from memory, users consistently included a square border. This indicated that users perceive the brand’s "face" specifically as the smartphone app icon (the blue logo inside a rounded square) rather than the standalone logo mark. ## Implementing the "Toss Formula" in Design * The research led to a refined brand identity formula: **White background + Black bold English font + Blue app-icon-shaped logo.** * In the "10 to 100" 10th-anniversary campaign, the company shifted away from all-blue backgrounds in favor of this white-based combination to maximize recognition. * Toss Pay payment screens were updated to remove blue backgrounds, adopting the white-and-black layout to align with how users intuitively identify the service. For UX researchers and designers, this case demonstrates that brand identity is often a composite of environmental cues rather than a single graphic. When moving a digital-first brand into the physical world, it is essential to look beyond the logo and identify the specific "visual formula" that triggers the user's memory of the product experience.

In an era where AI moderators and non-researchers handle the bulk of data collection, the role of the UX researcher has shifted from a technical specialist to a strategic guide. The core value of the researcher now lies in "UX Leadership"—the ability to frame problems, align team perspectives, and define the fundamental identity of a product. By bridging the gap between business goals and user needs, researchers ensure that products solve real problems rather than just chasing metrics or technical feasibility. ### Setting the Framework in the Idea Phase When starting a new project, a researcher’s primary task is to establish the "boundaries of the puzzle" by shifting the team’s focus from business impact to user value. * **Case - AI Signal:** For a service that interprets stock market events using AI, the team initially focused on business metrics like retention and news consumption. * **Avoiding "Metric Traps":** A researcher intervenes to prevent fatigue-inducing UX (e.g., excessive notifications to boost CTR) by defining the "North Star" as the specific problem the user is trying to solve. * **The Checklist:** Once the user problem and value are defined, they serve as a persistent checklist for every design iteration and action item. ### Aligning Team Direction for Product Improvements When a product already exists but needs improvement, different team members often have scattered, subjective opinions on what to fix. The researcher structures these thoughts into a cohesive direction. * **Case - Stock Market Calendar:** While the team suggested UI changes like "it doesn't look like a calendar," the researcher refocused the effort on the user's ultimate goal: making better investment decisions. * **Defining Success Criteria:** The team agreed on a "Good Usage" standard based on three stages: Awareness (recognizing issues) → Understanding (why it matters) → Preparation (adjusting investment plans). * **Identifying Obstacles:** By identifying specific friction points—such as the lack of information hierarchy or the difficulty of interpreting complex indicators—the researcher moves the project from "simple UI cleanup" to "essential tool development." ### Redefining Product Identity During Stagnation When a product's growth stalls, the issue often isn't a specific UI bug but a fundamental mismatch between the product's identity and its environment. * **Case - Toss Securities PC:** Despite being functional, the PC version struggled because it initially tried to copy the "mobile simplicity" of the app. * **Contextual Analysis:** Research revealed that while mobile users value speed and portability, PC users require an environment for deep analysis, multi-window comparisons, and deliberate decision-making. * **Consensus through Synthesis:** The researcher integrates data, user interviews, and market trends into workshops to help the team decide where the product should "live" in the market. This process creates team-wide alignment on a new strategic direction rather than just fixing features. The modern UX researcher must move beyond "crafting the tool" (interviewing and data gathering) and toward "UX Leadership." True expertise involves maintaining a broad view of the industry and product ecosystem, structuring team discussions to reach a consensus, and ensuring that every product decision is rooted in a clear understanding of the user's context and goals.

Toss designer Lee Hyeon-jeong argues that business goals and user experience are not mutually exclusive, even when integrating controversial elements like advertising. By identifying the intersection between monetization and usability, her team transformed intrusive ads into value-driven features that maintain user trust while driving significant revenue. The ultimate conclusion is that transparency and appropriate rewards can mitigate negative feedback and even increase user engagement. ### Reducing Friction through Predictability and Placement * Addressed "surprise" ads by introducing clear labeling, such as "Watch Ad" buttons or specifying ad durations (e.g., "30-second ad"), which reduced negative sentiment without decreasing revenue. * Discovered that when users are given a choice and clear expectations, their anxiety decreases and their willingness to engage with the content increases. * Eliminated "flow-breaking" ads that mimicked functional UI elements, such as banners placed inside transaction histories that users frequently mistook for personal bank records. * Established a design principle to place advertisements only in areas that do not interfere with information discovery or core user navigation tasks. ### Transforming Advertisements into User Benefits * Developed a dedicated B2B ad platform to scale the variety of available advertisements, ensuring that users receive ads relevant to their specific life stages, such as car insurance or new credit cards. * Shifted the internal perception of ads from "noise" to "benefits" by focusing on the right timing and high-quality matching between the advertiser and the user's needs. * Institutionalized regular "creative ideation sessions" to explore interactive formats, including advertisements that respond to phone movement (gyroscope), quizzes, and mini-games. * Leveraged long-term internal experiments to ensure that even if an idea cannot be implemented immediately, it remains in the team's "creative bank" for future product opportunities. ### Optimizing Value Exchange through Rewards * Conducted over a year of A/B testing on reward thresholds, comparing small cash amounts (1 KRW to 200 KRW), non-monetary items (gifticons), and high-stakes lottery-style prizes. * Analyzed the "labor intensity" of ads by adjusting lengths (10 to 30 seconds) to find the psychological tipping point where users felt the reward was worth their time. * Implemented a high-value lottery system within the Toss Pedometer service, which successfully transitioned a loss-making feature into a profitable revenue stream. * Maintained user activity and satisfaction levels despite the increased presence of ads by ensuring the "worst-case experience"—viewing ads for no gain—was entirely avoided. Product teams should stop viewing business requirements and UX as a zero-sum game. By focusing on user psychology—specifically transparency, non-disruption, and fair value exchange—it is possible to achieve aggressive business targets while maintaining a sustainable and trusted user environment.
