Copper Cow Coffee is the brainchild of Vietnamese-American Debbie Wei Mullin. Our dedication to the environment, and the coffee that you consume on a daily basis (let’s be real) stems from a few things: namely Debbie’s love for Vietnamese coffee and culture, and her background in sustainability work. 

Put that all together, and you’ve got us — quality-obsessed, eco-friendly, and proud to be part of the 2% (and growing) of women-owned companies with venture funding.

These days you’ll find us working tirelessly towards Debbie’s dream of making Vietnamese coffee a household product, all while sipping a healthy number of lattes in our cozy Los Angeles office.

Debbie Wei Mullin

CEO, Founder

Debbie was born in California, years after her mom arrived from Vietnam in 1975. She studied sustainability in college and had a stint at the World Bank before going all in on pursuing her love of Vietnamese coffee. Fun fact: Debbie’s got quite the athletic streak. Not only was she captain of her high school wrestling team, but you can also count on her to bust out the worm on any dance floor.

Jessica Franksen


Born and bred in Omaha, Nebraska, Jessica grew up with coffee (and entrepreneurship) in her veins, thanks to exposure to her dad’s coffee company. When she’s not booking impromptu trips abroad, finding new restaurants, or scoping out independent coffee shops, she’s busy doting on her one true love: her rescue pup, Olives Oprah.
