Embrain (corporate name Macromill Embrain) was founded in 1998 as Korea Panel Research, took investment from Japan-listed Macromill in 2012 and merged with Macromill Korea to adopt its current name, and listed on KOSDAQ in 2020.
The company runs three core business lines -- online research, offline research, and deep-data services -- built on Korea's largest survey panel of roughly 1.79 million members. Online research, which is faster and less costly than offline surveys, is described as the segment that has kept growing even in downturns.
The company has five subsidiaries including Embrain Public and Mindmagnet, extending its reach into opinion polling, content, and data analytics.
According to an older technical analysis report, the company had served more than 1,000 client companies annually with about 5,000 projects, suggesting a business model built on recurring, project-based revenue from a broad client base.
In Korea's market research and polling industry, large competitors such as Hankook Research exist, with Hankook Research described as the country's largest marketing and opinion-research firm.
In September 2026, Embrain launched a new market analysis service called 'CALI,' which combines search, purchase-behavior, and consumer-research data, signaling an effort to move beyond traditional surveys into data-tech territory.
Overall, the company appears to be layering data-analytics services on top of its traditional panel-infrastructure strength to seek additional value.
