Best Creative Agencies in Seoul (2026)

Introduction

Seoul’s creative agency scene runs from small idea-led independents to agencies tied to the country’s largest business groups, and the 7 agencies below cover that range. They were chosen for recent work, 2025 and 2026 recognition, and the strength of their client rosters.

Korean advertising has a strong in-house structure, with Cheil Worldwide linked to Samsung, Innocean to Hyundai Motor Group, HS Ad to LG and Daehong to Lotte. Independents have earned a good share of attention alongside them. Spikes Asia named Dminusone its South Korea Agency of the Year in March 2026, and The One Club’s 2025 ONE Asia Creative Rankings placed Innocean Seoul first in Asia and South Korea third among countries.

Every agency here has a Seoul office in 2026. The list runs in no fixed order of merit, and it is deliberately short: a firm was only included where its Seoul presence and current activity could be confirmed. Most of the group and network agencies appear on our advertising page instead.

The best creative agencies in Seoul

1. Ideot

Independent · Seongsu-dong · ideot.co.kr

Ideot is an independent agency whose stated approach is to solve every brief with an idea, often through a physical object or a public intervention. Its best-known recent piece, “Park O’Clock” for PLUGLINK, lets drivers tell each other when they plan to leave crowded apartment car parks. It won Bronze twice at Spikes Asia in 2024, along with Bronze at New York Festivals and ADFEST. Chief creative officer Seung-jae Lee sat on the Spikes Asia 2025 jury.

Samyang’s “Samyang Ramen High-Pressure Washer” won a Grand Prize at Korea’s 2024 Advertising of the Year awards and a YouTube Works award. Newer projects on its site include the “Applause Trophy” and a Seongsu-dong pop-up for the office furniture brand Fursys, and “Shining Work Pants”, a night-safety campaign for elderly farmers with Incheon Metropolitan City. The agency also lists a second office in Mapo-gu.

2. Studio K110

Kakao Entertainment · Gangnam · studiok110.com

Studio K110, known in Korean as 스튜디오좋, is a full-service agency founded in 2016 by Woori Nam and Jaewon Song, who met at Cheil Worldwide and still lead it together. Kakao Entertainment bought it in 2021. It has its own production unit and is known for worldview campaigns, in which a brand gets a fictional universe that runs across many instalments. In 2021 it won Agency of the Year at the Seoul Video Advertising Festival and a Grand Prize at the Korea Advertising Awards.

Its Binggrae and Lotte Chilsung Saero character campaigns are the reference points for this style. Recent work includes Crack collaborations with ZB1 and QWER for Wrtn Technologies, campaigns for Lotte Chilsung’s 2% and CJ CheilJedang’s Sobaba, and the Seoul launch of Sleep No More. The tone is deliberately offbeat, so review the reel closely if your brand sits at the formal end of the scale.

3. Dminusone

Led by CEO Janghan Kim · Seoul · LBB company page

Dminusone was named South Korea Agency of the Year at Spikes Asia 2026 in the festival’s Agency of the Year by Market list, published in March. Creative director and CEO Janghan Kim also sits on the 2026 ONE Asia Creative Awards jury.

We could not confirm a client list for this entry, so it stays with the recognition above. Ask for recent case studies and the named team early in any conversation.

4. AdQUA Interactive

Korean agency, founded 2000 · Gangnam · adqua.co.kr

AdQUA Interactive began in 2000 making shareable digital video and now describes itself as a digital-based communication agency. It builds websites and digital installations in-house, runs social channels, and handles search and display media on platforms such as Naver and Google. Its GS Caltex campaign “Maeum-ieum” took two Grand Prizes at the 2017 Korea Advertising Awards.

The client page is long and spans sectors, with names including Netflix, Olive Young, Amorepacific, Samsung Electronics and KakaoPay; it does not separate current from past work, so ask which accounts are live. In October 2026 the agency was selected for K Bank’s Boss Banking campaign for a second year and for social media operations for the baby brand Double Heart. Many clients work with it on annual contracts.

5. Dolphiners Films

Owned by Kakao Entertainment · Samseong-dong · dolphiners.com

Dolphiners Films, known in Korean as 돌고래유괴단, is a creative crew that makes campaigns, films, music videos and drama. The group formed around filmmaking in 2007. Kakao Entertainment acquired the company in 2021, and director Shin Woo-suk has said the deal guaranteed the team full creative freedom. Vice president Sunghun Lee is on the 2026 ONE Asia Creative Awards jury.

Its global work includes Apple’s “Shot on iPhone” with NewJeans and a Samsung Galaxy Watch campaign, and it directed NewJeans’ “Ditto” and “OMG” videos. Other clients include Jinro, Shinsegae, Uniqlo and SSG.COM. Dolphiners is led by directors and film craft, so it suits brands that want a piece of entertainment more than a full account service.

6. TBWA\Korea

Omnicom · Gangnam · tbwakorea.com

TBWA\Korea is the Seoul office of the TBWA network, part of Omnicom, which completed its acquisition of IPG at the end of 2025. It is included here for its run of idea-led work for Korean and global brands. It won five main awards at the 2025 Korea Advertising Awards, including a Grand Prize in audio and radio for the language app Speak.

The same awards recognised its “Shot on iPhone: Dirty Work” for Apple and a Twosome Place winter campaign. Other recent clients on its site include Binggrae, Coway, Aekyung Industrial, Kurly, Olive Young and the 2025 national census. It also takes on brand consulting, with projects for CGV and POSCO International.

7. Innocean

Hyundai Motor Group company · Gangnam · innocean.com

Innocean is the agency of Hyundai Motor Group, and Campaign Brief Asia’s 2025 Creative Rankings placed it first in Korea and sixth in Asia. Its Hyundai short film “Night Fishing”, shot entirely on an IONIQ 5’s built-in cameras, won the Film Grand Prix at Spikes Asia 2025 and helped it become Agency of the Year in The One Club’s 2025 ONE Asia Creative Rankings. In March 2026 it took 13 awards at ADFEST, the most of any Korean agency, and a new special award for Independent Network of the Year.

Much of its output serves Hyundai and Genesis, though recent award winners also include Binggrae’s “Hearing 1945”, Daangn’s “Come Back Home” and Samyang Foods’ “Ride the Buldak High”. In 2026 it launched Cinema by Brand, a platform connecting brands with the film industry, and unveiled it at the Busan International Film Festival. Clients outside the group may want to ask how their account will be staffed alongside the Hyundai work.

What to look for in a Seoul creative agency

Start with ownership. Group-affiliated agencies such as Innocean bring scale, international offices and steady investment, and much of their work comes from their parent groups. Smaller shops such as Ideot and Studio K110 usually put their founders close to the work. Ask any agency how its largest client shapes the time available for yours.

Look closely at how the agency builds an idea over time. Seoul shops have made a speciality of character-led campaigns and worldviews that run for years, as well as films and music videos that compete for attention with entertainment. These suit some brands very well, and they need a client who will commit past a single campaign and sign off on a less conventional tone.

Check the international reach if you plan to run work outside Korea. Awards at Spikes Asia, ADFEST and ONE Asia show that a team’s work travels, while a local Korea Advertising Awards record shows strength at home. Ask who handles English-language and overseas adaptation, and whether that person works in the Seoul team.

Finally, look at how the agency handles the day-to-day. A campaign with many films, edits and social cuts creates a lot of back and forth with the client. Ask where the files live, how feedback is gathered, and who records each approval, because these habits affect a long relationship more than a pitch will show.

How Fabric helps creative agency teams

Fabric gives an agency one workspace for its files, client feedback and team knowledge, with AI search across all of it. Agencies that run several accounts at once can follow the agency setup: one space per client, with briefs, assets, decks and call notes kept together.

Film and campaign files sit in Fabric’s cloud drive, which streams files on demand so they take no local disk space, and heavy files open without a full download. Search works by meaning across documents, images and transcribed recordings, and results jump to the page or timestamp. That helps when a long-running campaign has years of past instalments to refer back to.

Client review runs through sharing. Share a file or folder with the client as a commenter, and they can respond through the link without signing up. Commenters can leave timestamped comments on video and audio, draw on a video frame or an image and attach a comment, and highlight text in documents and PDFs. The team then marks each comment completed, so a round of feedback works like a checklist.

For finished work, any file or folder can be published as a web page, which is view-only with optional download. Link analytics shows when each named recipient opened a link and how long they spent with it, which is useful for pitch decks. On Team plans, self-writing docs maintain a page for each client from meetings, Slack and the workspace, covering decisions, deliverables and open items.

Link analytics and password protection are included on Pro and Team plans, and self-writing docs on Team plans. See plans for teams.

Frequently asked questions

What is the best creative agency in Seoul?

There is no single answer, as the right agency depends on the brief. On recent recognition, Innocean came first in The One Club’s 2025 ONE Asia Creative Rankings, Dminusone was Spikes Asia’s South Korea Agency of the Year in 2026, and TBWA\Korea won five main awards at the 2025 Korea Advertising Awards.

Are Cheil Worldwide and HS Ad on this list?

No. This page focuses on independents and integrated idea shops, with two larger agencies included for their recent creative work. Group and network agencies such as Cheil Worldwide and HS Ad are covered on our list of the best advertising agencies in Seoul.

Are there independent creative agencies in Seoul?

Yes. Spikes Asia describes Ideot as a Korean independent. Ownership varies more than the names suggest: Dolphiners Films and Studio K110 have both belonged to Kakao Entertainment since 2021, so it is worth asking any agency directly.

Which Seoul agency suits a film-led campaign?

Dolphiners Films is built around directors and has made work for Apple, Samsung and NewJeans. Innocean’s “Night Fishing” won the Film Grand Prix at Spikes Asia 2025. If you already have the idea and need a production partner, see our list of video production companies in Seoul.

What is a worldview campaign?

It is a campaign that gives a brand its own fictional universe, usually with recurring characters, and extends it across films, social content and products. Studio K110 is closely associated with the approach through its work for Binggrae and Lotte Chilsung’s Saero. It needs a longer commitment than a single burst of advertising.
