S2W was founded in 2018 as S2W Lab Inc. and renamed to its current form in 2021, listing on KOSDAQ on August 19, 2025 under the technology growth company special listing track.
The firm is an AI data intelligence company that analyzes unstructured data collected from hidden channels such as the dark web and Telegram, based on knowledge-graph-driven cross-data analysis technology, and has developed its own dark-web-specialized AI model 'DarkBERT' and security-document-specialized model 'CyBERTuned.' Its core solutions consist of three products: 'XARVIS,' a security platform for public and government institutions, 'QUAXAR,' an enterprise security solution, and 'SAIP,' an industry-specific AI platform.
As of 2024, revenue mix stood at 42.1% for QUAXAR (enterprise security AI), 40.5% for XARVIS (security AI), 15.2% for SAIP (industry-specific AI), and 2.3% for other.
A government- and public-institution-centered customer base is regarded as the starting point of its growth strategy, with the company having built references by supplying solutions to global government agencies including Interpol, Japan, Singapore, and Saudi Arabia, using this foundation to expand into private enterprise customers.
Founded by a team centered on KAIST researchers, the company is recognized as one of the largest collectors and analyzers of dark-web data globally, and drew industry attention in 2023 by unveiling 'DarkBERT,' the world's first dark-web-specialized AI language model, at ACL, a top computational linguistics conference.
Its revenue structure carries a high SaaS weighting; at the time of listing the company had posted an average annual revenue growth rate of 81% since founding, with SaaS accounting for 69% of revenue.
Competitively, it coexists with large domestic security firms such as AhnLab while emphasizing technical differentiation in the narrow dark-web-specialized domain, alongside global partnerships such as integration with Microsoft's 'Copilot for Security.'
