Arkdata

What Arkdata does

Arkdata (주식회사 아크데이타 / ArkData Co., Ltd.) is a Korean data integration platform vendor founded in 2002 and headquartered in Seoul, with a regional office in Daegu. The company builds and sells real-time data replication and integration software centered on a proprietary CDC (Change Data Capture) log analysis engine developed domestically in Korea. Its product line comprises five core solutions: Ark for CDC (heterogeneous database replication across different DBMS and operating systems), Ark Connector (CDC-based Kafka connector for real-time event streaming, plus a Hadoop variant), Ark for Oracle (Oracle-specific Redo Log extraction with switchover/failover), Ark for FR (block-level file replication), and Ark UniStream (rule-based data standardization to structured JSON, launched December 2025). Integrations span Oracle, Tibero, PostgreSQL, MySQL, MariaDB, Apache Kafka, and Hadoop, with listings on Oracle Cloud, NHN Cloud, Naver Cloud, and Kakao i Cloud Marketplaces.

The company serves financial institutions, government and public-sector agencies, healthcare providers, universities, retail/e-commerce platforms, and logistics enterprises in Korea and select Asia-Pacific markets (Singapore, Sri Lanka, Bangladesh, Vietnam, Malaysia). Named customers and case studies include Hyundai Home Shopping, OK Bank Indonesia, Kyungpook National University, and the 2025 National Information Resource Management Service. Distribution is primarily channel-led: an exclusive domestic agreement with AJ ICT (signed April 2023, covering 100+ Korean customers/partners) and a sole APAC distribution agreement with Singapore-based One Lexiicon (August 2023), supplemented by SI and implementation partners such as DataHeaven, Timegate, DMI Systems, Equnix Business Solutions, Tinhvan, and Oslo Consulting. GTM combines enterprise field sales, channel/reseller distribution, and cloud marketplace subscriptions.

Revenue is generated through four streams: (1) traditional perpetual software licenses for Ark CDC, Ark Connector, Ark for Oracle, and Ark for FR; (2) recurring monthly cloud subscriptions via four cloud marketplaces; (3) channel and distribution revenue from exclusive and sole distribution partners; and (4) professional services for implementation, migration, and support. Pricing is not publicly disclosed; multi-year enterprise contracts and migration term licenses (priced at roughly 1/10 the cost of competing solutions) are the dominant commercial structures. The company holds Grade 1GS Korean government certification and registered patents on its CDC log analysis engine. Ownership appears concentrated with founding management (CEO Ko Kwang-yun / 고광연), with no disclosed institutional investors, parent company, or public listing.
