Company profile

researched Aug 2026

코르카 (Corca) is a Seoul-based artificial-intelligence company founded on 2021-10-28 and headquartered at 34 Yeongdong-daero 85-gil, Gangnam-gu, Seoul. It develops AI agent services and B2B solutions in areas such as document/paper comprehension, schedule management, memory storage and retail media advertising. Reported products include Moonlight (문라이트), a tool that helps users understand academic papers, and Trace, an AI-based scheduling application. Company keywords associated with the business are AI Agent, hyper-personalization, B2B solution and LLM.

The company frames its work around applying advanced AI engineering and product planning to enterprise data and pain points, delivering customized and sustainable solutions rather than acting solely as a technology vendor. Its stated values center on data transparency and privacy, broad accessibility of AI, industry-specific partnership, global expansion and continuing research around large language models. Corca also maintains a public engineering presence through its corca-ai GitHub organization, whose repositories include awesome-llm-security (an LLM security resource curation), EVAL (a LangChain-based agent), LLMFuzzAgent, AIvilization, WebAssembly-based TeX and PowerPoint engines, a Rust clone detector, and a 7th-place solution to the RecSys Challenge 2023.

As of the company profile data available, Corca had roughly 30 staff, of whom about 24 were developers; an earlier team description cites 20 members with a developer share above 70% and an average age in the mid-20s. The organization operates a flexible working-hours system with a core co-work time of 10:30–16:00, supports remote work, and funds equipment, books, courses and AI tool subscriptions such as ChatGPT, Claude and Cursor.

Founding story

Corca was founded on the premise that enterprises hold varied data and unmet needs, and that advanced AI engineering combined with product planning can deliver customized, sustainable solutions that generate business value. CEO 정영현 graduated from Seoul Science High School and Seoul National University's Department of Computer Science and Engineering, holds a master's degree from NYU, completed doctoral coursework at the University of Pittsburgh, and previously co-founded an IT startup as co-founder and development lead.
