Mastermind is all about perfection.

We want you to love coffee as much as we do. And while we know that cold brew is the best coffee you can get, brewing it hasn't been as easy as popping a pod into the Keurig or just buying Starbucks. That's why we are working hard every day to perfect products that innovate within the cold brew marketplace and fit into the fast-paced, on-the-go lifestyle of every working class American.

We give back.

Our product gives back to nature, using recycled materials in the packaging and steel.
15% of our profits go to Charity: Water, a nonprofit organization that delivers clean water projects for villages in need.
