Intrix

Intrix (Intrix Inc., 주식회사 인트릭스) is a South Korean agency specializing in Generative Engine Optimization (GEO) and technical SEO, headquartered in Busanjin-gu, Busan. The company positions itself as a specialist that helps brands appear in answers generated by AI search services such as ChatGPT, Gemini, and Perplexity, rather than only in traditional search engine results. Its stated belief is that explaining a brand to people and explaining it to search engines and AI are not fundamentally different: consistency of message, clarity of meaning, and accumulation of trustworthy third-party evidence are the core levers. Intrix operates as a deliberately small, one-person company. Its founder and growth lead, Jung Sung-hoon (정성훈), describes a 15-year marketing career spanning advertising agency leadership, an advertising platform startup, a video production board seat, and senior GEO consulting. The company states it limits concurrent engagements to at most five brands so that the person who observes the data is also the person who executes the work. Services span pre-diagnosis, GEO consulting, content and external-information cleanup, and website implementation, and the company says it can start even for brands without an existing website. Beyond consulting, Intrix builds and runs its own tools and platforms. These include Intrix-CT, an AI search and citation observation system; Intrix-Audit, a site diagnostics crawler; Intrix-Diff, a competitor comparison tool; and K-DermZIP (kdermzip.com), a dermatology information platform covering thousands of South Korean clinics in four languages and built on Health Insurance Review and Assessment Service (HIRA) public data. The company says it prioritizes medical and legal fields, where verifiability is especially important, and it explicitly states that it does not guarantee specific search rankings or AI citations. Intrix was founded in 2026 and is registered in Busan with business registration number 312-87-04098. It has attracted South Korean technology press coverage for its patent filing on diagnosing citation bottlenecks in generative AI search, for the development of Intrix-CT, and for the launch of K-DermZIP.

Intrix (Intrix Inc., 주식회사 인트릭스) was founded in 2026 in Busan, South Korea, by Jung Sung-hoon (정성훈), a marketer and developer with roughly 15 years of experience. According to the company's own account, Jung previously served as CEO of an advertising agency, as a general director at an advertising platform startup, as an outside director of a video production company, and as a lead consultant at a GEO agency. He also describes himself as a platform builder who has planned and operated K-DermZIP and two other vertical platforms. The company was established around the emerging discipline of Generative Engine Optimization (GEO), also called AI search optimization. GEO concerns how AI systems such as ChatGPT, Gemini, and Perplexity select and cite sources when composing answers, a different problem from conventional search ranking. Intrix's stated approach combines technical SEO foundations with content and external-information work, and it frames the task as a branding problem: consistency of message, clarity of meaning, and accumulation of third-party trust signals across the web. From its founding, Intrix chose to remain a one-person company rather than grow an organization. The company says this is so that the person who observes the data also makes the judgments and executes the work, and it caps concurrent employment-style consulting and long-term projects at five brands. Its service flow begins with a pre-diagnosis that identifies the customer questions and channels worth focusing on, then connects GEO consulting, content work, external-information cleanup, and website implementation. Intrix states that a brand does not need an existing website to begin, since customer questions and the external sources cited in AI answers can be researched independently. Intrix also builds its own technology rather than only advising clients. It developed Intrix-CT, an AI search and citation observation system that goes beyond measuring citation rates to analyze how AI expands queries, explores sources, and finally cites them, so a brand can see at which stage it diverges from competitors. It built Intrix-Audit, a site diagnostics crawler covering up to 250 pages with more than 70 judgment items and 303 regression tests, and Intrix-Diff, a competitor comparison tool whose measurements found that roughly one third of cited pages ranked below position 11 in search. The company also operates K-DermZIP (kdermzip.com), a dermatology information platform covering 3,633 clinics nationwide in four languages (Korean, English, Japanese, and Russian), built on Health Insurance Review and Assessment Service (HIRA) public data and designed so that overseas users asking generative AI services about Korean dermatology clinics can find that information. In 2026 the company drew South Korean technology press coverage on three fronts. In May, eNewsToday reported the launch of K-DermZIP as an early example of building GEO infrastructure in the medical sector. In August, AI Times covered the development of Intrix-CT. In September, ITBizNews reported that Intrix had filed a patent on September 11 for a 'method and system for determining website citation bottlenecks in generative AI search.' Intrix states that it prioritizes medical and legal fields because verifiability is especially important there, and it explicitly does not guarantee specific search rankings or AI citations. The company is registered in Busanjin-gu, Busan, with business registration number 312-87-04098.
