Meet Hyein Yoon
Hyein Yoon is a globally recognized marketing expert, content creator, and the Founder of HY Marketing. Her journey in the marketing industry began when she was awarded the 1st Prize for the Gyeongui Line Book Street Promotion (issued by the Korean Publishers Cooperative) in South Korea as Project Team Leader in 2017. Since then, she has delved into various aspects of marketing as a freelancer as well as working as a proud content manager and project manager for the Women’s Human Rights Institute Of Korea. During this time, she had the opportunity to collaborate with major platforms like Google, Facebook, and other social media channels, allowing her to gain valuable insights into SEO and social media algorithms.
With a passion for making a positive impact, Hyein also served as a social media manager for global NGOs before venturing into freelancing in 2020. This transition opened doors for her to work with diverse clients, which led to the establishment of HY Marketing. To ensure top-notch service delivery, she built a global team consisting of marketers who are native speakers in Japan, South Korea, and English-speaking countries dedicated to providing high-quality solutions for her clients.
Although Hyein initially dreamed of becoming an AE (Account Executive) during her high school years, she had to put that dream on hold to focus on earning a living. However, her varied career experiences and unstoppable personal growth have ultimately led her to fulfill her entrepreneurial aspirations as the founder of HY Marketing. This journey has fueled her creativity and flexibility in her work.
Hyein is a firm believer in the power of mindset and is always seeking new challenges. She is fully committed to HY Marketing, her global digital marketing agency. Additionally, she takes great pride in being a member of The Social Clique by Rachel Pedersen who is renowned as The Queen of Social Media.
HY Marketing was also honored with the 1st Prize in the 2022 Goyang City DreamMaru Women Entrepreneurship Business Development Grant Competition.
