In 2005 to 2008, Yoon started his career in finance at JP Morgan Chase. He learned three things during this time. First, that he loved finance. Second, that ecommerce is very similar to finance. Third, he learned he wanted nothing to do with the finance industry, but still wanted to apply his financial skills to help companies that align with his personal values.
In 2011, Yoon started Outdoor Ecom with a vision to help top outdoor brands reach their ecommerce potential. In 2015, he started Outdoor Media Summit, the conference for media and marketers in outdoor, and in 2016, he started Gearography, a gear blog for adventure travelers.
