How to Find agencies in Seoul — A 2026 B2B Lead Guide

Seoul has one of the densest concentrations of agencies in its region. If your ICP is agencies located in Seoul, this guide shows you where those accounts cluster, who the decision-makers are, and how to contact them with verified emails and direct dials.

Quick answer

The fastest way to find agencies in Seoul is to run a natural-language search on ProLeads: describe the role, industry, and city in a sentence and export verified contacts to your CRM. Expect 50–500+ matches for most mid-to-large metros, with 97% data accuracy on emails and direct dials.

Why Seoul matters for advertising agencies sales

Seoul is known for electronics HQs, gaming & entertainment, and fintech. For sales teams selling into agencies, that mix creates a concentrated buyer base — and a signal-rich environment for account prioritization.

Creative, media-buying, and integrated ad agencies. In Seoul specifically, agencies tend to over-index on new business and margin, which is the angle your outreach should lead with.

Decision-makers to target at agencies in Seoul

When selling into agencies, three titles consistently convert better than broad departmental targeting:

Managing Director — typically owns budget approval for vendor selection in this space.
Head of New Business — typically owns budget approval for vendor selection in this space.
CEO — typically owns budget approval for vendor selection in this space.

Layer seniority filters on top of the role — Director-level and above for platform buys, individual-contributor level for bottoms-up PLG motions.
