Slate

It might be hard to imagine just a few years ago that an ultra-filtered canned chocolate milk brand would be drawing so much attention and investment, but, amidst booming demand in high-protein products, Slate Milk is doing exactly that.

And appropriate for a brand that is “selling strength,” as co-founder Manny Lubin told us in 2023, the gains have been clearly apparent. Slate has spent 2025 growing its distribution footprint to 20,000 stores (Target, Albertsons and Sprouts among them), along with closing a new $23 million investment round. Along with a fresh tranche of growth capital, Slate added to an already diverse group of strategic investors which includes the founding team of frozen Greek yogurt brand Yasso, UFC president and CEO Dana White, actor Jonah Hill and DJ/producer Diplo, among many others. 

That expansion has validated Slate’s differentiated approach, whether it's tapping into college influencers via NIL or helping establish aluminum’s place in the protein category. With its new three-SKU Ultra sub-line (42 grams of protein) complementing canned entries at 20 grams and 30 grams, the Boston-based brand is poised to keep pushing forward.
