About Us
A digital marketing partner helping clients achieve sustainable growth through ethical practices.
CEO
Message
A commitment to excellence.
Hello, I'm Jyongchul Lee, CEO of Whitehat Marketing Co., Ltd.
Since founding the company in 2013, I have connected SEO/AEO, data, and web platform development to support sustainable client growth.
Whitehat Marketing is not built only to raise rankings. We design the full path from discovery to trust, inquiry, and operating follow-through by connecting SEO/AEO, content, websites, data structure, and automation.
The founder's education and global language background are detailed in the expertise section below. What matters most is translating biology, computer science, accounting, Chinese-language study, and software engineering into customer research, keyword strategy, localization, conversion design, and implementation.
For every project, we review market potential, customer psychology, search intent, technical structure, and operating risk together. The goal is reusable content assets, data-informed decisions, and durable digital trust, not short-lived exposure.
Throughout every process, we maintain transparency and accountability, protecting your digital assets through ethical approaches that strictly adhere to search engine guidelines.

Jyongchul Lee, Founder
Harvard University Alumni Jyongchul Lee has led SEO/AEO strategy and web-platform development projects directly since founding Whitehat Marketing in 2013. His background combines biology studies at Cape Breton University, neurobiology, biology, and computer science coursework at Harvard University, finance and accounting studies at KIMEP University (Kazakhstan Institute of Management, Economics and Strategic Research), two years of Chinese-language study at Tsinghua University and Beijing Language and Culture University(BLCU), and software engineering studies at Korea Cyber University.

His Korea Cyber University transcript-backed coursework includes AI (A+), Python machine learning (B+), machine learning and big data analysis, Spring Framework (A+), software development security (A+), big data, databases, web programming, investment, accounting, information-protection law, and privacy, while MS-SQL/MySQL operations, branding and PR strategy, and KMARIN fundraising and logistics sales experience help turn search acquisition, inquiry conversion, data structure, and operating automation into usable digital assets.
