Manny Lubin and Josh Belinsky co-founded Slate with the goal of creating a healthy chocolate milk they could drink every day. After a successful Kickstarter campaign, an appearance on ABC's Shark Tank, and hundreds of iterations of testing, Slate launched in late 2019 with three delicious chocolate milk flavors. Today, Slate has expanded into new flavors and additional product lines, all of which contain 20g protein, have 0g added sugar, are lactose free, and 100% plastic neutral.
