Upon his return, he took over operations of Shany, a subsidiary of his father's parent company, Samlip Food Corporation. In 1986, Hur launched a French-style bakery called Paris Croissant. In 1988, his company launched a franchise brand called Paris Baguette, which facilitated parbaking, or 'bake-off system', to allow franchisees to bake products in-store.
Upon successfully growing his franchise Business in South Korea and abroad, Hur founded the parent company, SPC Group in 2004, and relocated his subsidiaries, Paris Croissant, Samlip Food Corporation (now renamed SPC Samlip), and BR Korea. BR Korea is a joint venture for Baskin Robbins and Dunkin' Donuts operations in Korea.
The 2010 Korea Broadcasting System television drama King of Baking, Kim Takgu (English title: Bread, Love and Dreams) is based on Hur's experience as a child overcoming hardships to make quality bread and grow his Business.
