Tidy-B provides an artificial intelligence (AI)-based all-in-one branding solution called “Yo-B.” Yo-B offers the entire branding process on a single platform, from brand strategy development to design creation, content operation, and performance analysis. Another feature of Yo-B is that it consistently maintains brand DNA. This enables non-experts to carry out branding at a professional level.

Recently, Tidy-B rebranded its AI all-in-one branding solution from “Tidy-B” to “Yo-B” in order to more clearly reflect the identity of the solution. From this point, various convenience features have also been added. Leveraging the Yo-B rebranding, Tidy-B plans to secure small business and startup customers in Korea and expand its business scope to Japan and Southeast Asia.

Tidy-B CEO Jang Jong-hwa spoke about the Yo-B rebranding, new features, and future strategies.


Founded to support small business branding

IT Donga: Please introduce yourself and Tidy-B.

CEO Jang Jong-hwa: This is Jang Jong-hwa from Tidy-B. I have worked in corporate branding for more than 15 years. While running a digital agency, I consulted on branding for around 100 companies and developed designs, websites, and apps.

During that process, I realized that most small businesses and startups recognize the need for branding but are unable to even get started. Costs running into tens of millions of KRW served as an entry barrier. To lower this barrier, I founded Tidy-B in 2021. Under the goal of “helping anyone complete professional-level branding at an affordable cost,” we are now developing and operating the AI all-in-one branding solution Yo-B.

Rebranding to redefine the solution’s identity

IT Donga: Yo-B was previously offered under the name Tidy-B and was recently rebranded. What was the reason for the rebranding?

CEO Jang Jong-hwa: There are three reasons behind the decision to rebrand. First, as new features were added, the solution evolved, making it necessary to redefine its identity. When Yo-B was first launched in 2021, it was merely an online brand guideline service. Now, however, it has developed into an AI all-in-one branding solution that covers everything from brand strategy and content creation to automatic posting and performance analysis. We therefore concluded that a new name was needed.

Second, we wanted to enhance brand accessibility. We had often heard from clients that the previous name was not intuitive. So we started to consider a name that would capture the nature of the service as much as possible while being intuitive and friendly.

Third, we sought to reset our relationship with users. Whereas Tidy-B gave a strong impression of being a “tool that tidies up,” Yo-B incorporates a more proactive perception as “a partner that creates your brand together with you.” Branding is not a one-off process but an activity that must be managed every day, so we believed it should be perceived as a partner that is with users daily.

For these reasons, we changed the name to Yo-B in January this year. For reference, Yo-B is an abbreviation of “Your Brand,” capturing the core value of our solution—“your brand”—while being short and easy to remember. Another advantage is that it can be pronounced naturally not only in Korea but also overseas.


IT Donga: What do you expect to achieve through the rebranding?

CEO Jang Jong-hwa: We expect clearer market positioning, stronger recognition in global markets, and a shift in internal energy. Previously, there was some ambiguity as to whether we were a design tool or a branding consulting solution. With the shift to Yo-B, we have clearly defined our identity as an “AI branding agent.” We anticipate that this will clearly communicate to customers that we are not just a simple editing or posting tool but a solution that autonomously connects the entire process from brand strategy to performance improvement. In addition, starting this year, we plan to fully scale up our entry into the Japanese and Southeast Asian markets. We expect the new name and identity to provide a fresh first impression to local partners and users. Internally at Tidy-B, the rebranding is also serving as an opportunity to feel that we are entering a full-fledged scale-up phase.

Branding made easily accessible to beginners: AI all-in-one solution Yo-B

IT Donga: Please explain Yo-B in more detail.

CEO Jang Jong-hwa: Yo-B is an AI all-in-one branding solution that handles the entire process—from brand strategy development and design creation to content operation and performance analysis—on a single platform. Existing branding tools are fragmented in terms of functionality. Design editing tools make it difficult to establish brand strategy or maintain consistency, while content posting tools lack design features. As a result, small businesses and small companies had to jump between multiple tools, which required significant expertise and time for each tool. It was also difficult to maintain brand consistency. Yo-B integrates these fragmented branding features into a single solution.

To look at it more specifically, AI converses with users to complete a brand strategy by defining brand objectives, vision, and core values (Brand Strategy). It then establishes a visual identity by creating brand design guidelines such as logos, colors, and fonts that match the strategy (Visual Identity). It automatically generates content—such as social media posts, digital advertisements, offline promotional materials, and documents—in line with the brand DNA (Content Design). Brand management (Brand Management), including marketing content automation, multi-channel automated posting, and performance collection and improvement, is also handled by Yo-B.

The strength of Yo-B lies in its ability to consistently maintain brand DNA throughout the entire branding process. Its proprietary BCS (Brand Consistency Score) engine inspects design elements in real time to secure consistency. As a result, non-experts can achieve professional-level outcomes.


IT Donga: It is understood that new or improved features were added during the rebranding.

CEO Jang Jong-hwa: We enhanced the scope and depth of automation through three key features. First is the large language model (LLM)-based automatic brand DNA extraction function. For users who already have a brand, AI automatically collects information and precisely extracts design elements that match the brand DNA by simply entering the website URL. This becomes the reference point for all subsequent content creation.

We also advanced the BCS engine. Every time content is generated, it automatically evaluates color consistency, font suitability, logo guideline compliance, layout rules, and tone similarity. We then apply a cut-off policy under which a score of 90 or higher passes, 85–90 requires minor adjustments, and below 85 triggers regeneration, thereby systematically maintaining brand consistency.

We also carried out a complete overhaul of the design editor. This is a web-based real-time vector editor that allows users to instantly modify generated content and convert it into various formats and ratios such as JPG, PNG, and PDF.

IT Donga: How is Yo-B’s pricing structured?

CEO Jang Jong-hwa: Yo-B is provided as software-as-a-service (SaaS), and pricing is divided into “AI Subscription” and “Pro Subscription.” The AI Subscription is a model in which users conduct branding themselves using Yo-B, and it is available in Free, Basic, and Plus tiers depending on features, credits, and storage capacity. The Pro Subscription combines Yo-B with expert support. Through expert support, users can establish branding strategies and produce websites and apps, promotional booths, videos, spatial designs, brand merchandise, and more.

The pricing plans are designed to be flexibly selected according to a company’s situation and growth stage. Companies can start with the free plan to experience branding, then upgrade to Basic or Plus as needed, and finally switch to the Pro Subscription as they grow. Through this, we aim to be a branding partner suited to each stage, from small businesses to growth-stage companies.


IT Donga: Please also share Yo-B’s achievements to date.

CEO Jang Jong-hwa: Yo-B currently has around 1,400 members and more than 200 paying corporate customers. Cumulative sales exceed KRW 1 billion. On the technology side, we have filed two patent applications related to generative AI-based branding services and brand-based design templates, and we have obtained two performance certifications from the Telecommunications Technology Association (TTA), the Korea Software Testing & Certification Institute. Through various support programs, we are also expanding cooperation with large corporations. By supporting branding development and providing design automation solutions for affiliates of large conglomerates, as well as supporting small business start-ups, we are demonstrating the applicability of Yo-B.

Additional user convenience features and plans to target Japan and Southeast Asia

IT Donga: Are there any features that are scheduled to be added to Yo-B?

CEO Jang Jong-hwa: After being selected last year for the TIPS (Tech Incubator Program for Startup) private-investment-led technology start-up support program, we have been developing several features. First, we are working on a “daily automatic design suggestion” feature. AI will provide content suitable for posting each day by comprehensively analyzing past post performance, the latest trends, weather, and seasonal topics. Users can simply review the preview and press the approval button to have the content posted immediately. We expect this to significantly reduce the burden on small businesses in terms of content planning and production.

We also plan to introduce a multi-channel automatic customized posting function. This feature will allow content to be posted simultaneously across multiple channels such as social media and blogs, automatically converting it to meet each channel’s specifications in terms of image ratios, text length, hashtags, and so on. We are also developing a function to handle scheduled posting.

In addition, we are developing a performance self-improvement module. AI will analyze metrics such as click-through rates, customer responses, and sales conversions in real time, derive areas for improvement, and automatically reflect them in subsequent content production. The more this feature is used, the better it will perform and the more closely it will be tailored to each brand. All of these features are scheduled to be released within this year.


IT Donga: Finally, please share this year’s plans and your long-term goals.

CEO Jang Jong-hwa: Having completed the rebranding, we intend to pursue full-fledged scale-up this year. In Korea, we plan to first target small business owners who run online shops. We will actively promote Yo-B to these small business owners, who need to create content every day but lack time and expertise, in order to secure them as customers.

In parallel, we are planning global expansion into markets such as Japan and Southeast Asia. Japan has many small and medium-sized enterprises and a strong preference for high-quality services, while countries such as Vietnam and Thailand in Southeast Asia are seeing rapid growth in social commerce, leading to surging demand for automated branding content solutions. We plan to operate pilot programs in the Japanese and Southeast Asian markets and then fully launch our global expansion.

Our ultimate goal is to become an “AI branding infrastructure that realizes every entrepreneur’s dream.” The global branding market is forecast to grow to approximately KRW 120 trillion by 2033. We will continue to move forward so that Yo-B can establish itself as the optimal solution in this market.
