30 Best Influencer & Social Media Marketing Agencies in Korea
Global companies looking to enter the Korean market and Korean companies looking to promote their products and services in Korea need influencer marketing. Influencer marketing agencies act as intermediaries between companies and influencers. This is very important for global companies that may have language barriers when dealing with content creators.
Influencer marketing is, in our opinion, the best way to spend digital marketing budgets in Korea. This is because it is extremely difficult for Korean companies to find and contact influencers in Korea (most of whom do not speak English), select the right influencers for their brands, and then actually run ad campaigns.
In this article, we will introduce 10 of the most popular influencer marketing agencies in Korea
Current State of the Korean Market
South Korea has an extremely high level of internet and mobile connectivity, with reports indicating that the internet usage rate had reached 97.4% as of early 2025.
The number of social media users also stood at approximately 48.9 million as of January 2025, equivalent to 94.7% of the population.

Such a high level of penetration indicates that influencer marketing has firmly established itself as a highly effective marketing method.
By platform, survey reports show that KakaoTalk still maintains the largest number of users, followed by YouTube and Instagram.
From this structure, it can be interpreted that in the Korean market, KakaoTalk serves as a foundation for message-based communication, YouTube functions as a platform for understanding video content, and Instagram plays a role in brand experiences and visual appeal.
In addition, the spread of short-form videos and live streaming has accelerated, further strengthening the model in which influencers and creators drive purchasing behavior through product reviews, introductions, and live demonstrations.
The market size of influencer marketing is also on the rise. For example, one study estimated that the Korean influencer marketing platform market was valued at approximately 237 million USD (over 30 billion JPY) in 2024, with a projected CAGR of 22% from 2024 to 2031.
These figures suggest that influencer-driven promotions are not merely a passing trend, but have become a permanent fixture within Korea’s marketing structure.
A distinctive strength of the Korean market lies in the influence of “K-beauty” and “K-pop culture”, which makes influencer-led communication highly effective not only for domestic consumption but also for cross-border and global expansion.
For instance, messages shared by K-pop idols and Korean beauty influencers often spark brand awareness and purchasing activity across Asia and Western markets. This “culture-driven communication” can be seen as a defining characteristic of Korea.
Furthermore, Korean consumers are highly receptive to new technologies—such as AR and live commerce—and to new video formats, creating a market environment where influencer-led experience-sharing content achieves results more easily compared to other countries.
Taken together, these points indicate that when developing influencer marketing strategies in Korea, success hinges on understanding three key perspectives: the high penetration of social media, the diversification of platform functions, and the cultural strengths that drive communication.
Choosing the Right Agency
To succeed in influencer marketing in Korea, it is not enough to simply hire popular influencers.
With social media usage exceeding 94% and cultural elements such as K-pop and K-beauty directly influencing purchasing behavior, it is essential to choose an agency that deeply understands local culture and platform characteristics while being able to optimize strategies based on data.
Below, we explain four key points to focus on when selecting an agency.
Familiarity with Korean Culture and Trends
In Korea, consumers tend to place strong importance on “empathy.” Rather than polished advertising-style content, they prefer authentic experiences and trustworthy communication.
This is also highlighted in a DataReportal study, which shows that the main purposes of social media usage in Korea are overwhelmingly centered on entertainment and review browsing.
Therefore, the ideal agency is not one that simply handles translation or distribution, but one that can craft stories tailored to Korean lifestyles and trends.
In particular, in sectors such as K-beauty, fashion, food, and tech, marketing narratives that take cultural context into account directly influence purchasing motivation.
Since Korean consumers value “opinions from people who share similar values with themselves,” it is more effective to select agencies that consider emotional connections when choosing influencers.
Breadth and Expertise Across Platforms
In Korea, YouTube and Instagram are the most influential social media platforms, with YouTube alone reaching a monthly usage rate of around 88%.
Instagram directly drives purchasing behavior among younger consumers, while TikTok is also on the rise.
In addition, local platforms such as KakaoTalk and Naver Blog retain strong influence.
Therefore, whether an agency can manage multiple platforms in an integrated way becomes a major criterion for selection.
Agencies that can propose strategies combining video production, live commerce, and user-generated content (UGC) are able to execute more flexible campaigns.
Rather than firms that specialize in only one medium, comprehensive agencies that can optimize platform usage according to campaign objectives are more effective.
Data-Driven Analysis and Reporting Systems
In Korea, the emphasis on the cost-effectiveness of social media advertising has been increasing year by year.
In influencer marketing in particular, more sophisticated metrics such as engagement rate and the percentage of positive comments are valued over sheer follower count.
As a result, “data-driven” agencies that can handle both performance measurement and improvement proposals tend to be preferred.
For example, agencies that can visualize CTR (click-through rate) and CV (conversions) after posting, and reflect those insights in subsequent campaigns, are able to execute PDCA cycles in a short timeframe.
Moreover, the number of companies using AI and machine learning to analyze influencer performance is also growing.
Such agencies are considered more reliable because they explain outcomes with data rather than intuition.
Multilingual Support and Legal Compliance Systems
Korea sees significant entry from global brands, and an increasing number of agencies now provide support in English and Japanese.
For overseas companies conducting marketing activities, the ability to handle contracts, invoices, and performance reports in multiple languages is a critical operational factor.
In addition, the Korea Fair Trade Commission (KFTC) requires influencers to clearly disclose advertising posts by marking them with labels such as #광고 (advertisement) or #협찬 (sponsored).
Choosing an agency that complies with legal requirements while ensuring transparency helps protect brand trust.
It is also important to confirm whether the agency has staff proficient in Korean, English, and Japanese, as this helps prevent misunderstandings caused by cultural differences.
Companies that manage a large number of global projects tend to have such multilayered systems in place.
