KT Nasmedia will launch a service that analyzes in advance the reach and expense efficiency of ad campaigns based on Netflix user data.
KT Nasmedia said on the 20th that it has integrated Netflix's official advertising API with its in-house integrated ad-effect analysis solution "Remix," the first in Korea. Before running a campaign, advertisers can review how many users will be exposed to the ads according to the budget and examine whether they can sufficiently reach the desired customer segment.
The service uses Netflix's "Reach Curve API," which calculates the expected number of people reached based on changes in ad spend. The company noted that, by reflecting Netflix's own first-party data rather than estimates from external research agencies, advertisers can judge more precisely the appropriateness of expense scale and targeting settings.
Netflix introduced an ad-supported plan in November 2022 in 12 countries, including Korea, and has since expanded the related business. In 2025, it expanded its in-house ad platform "Netflix Ads Suite" to countries operating the ad-supported plan and strengthened interest targeting and ad performance measurement features.
KT Nasmedia plans to advance Remix by combining it with its own artificial intelligence technology to enhance potential customer prediction and ad budget allocation functions. The company said it aims to help advertisers establish Netflix ad strategies based on data rather than relying on experience or estimates.
