The problem

You don't skip protein because you don't care.

You skip it because every option asks too much at exactly the wrong moment.

Between meetings

The bar is 220 calories of chewing through your 10am call. Dense, dessert-coded, and somehow still in your bag from last month.

After the run

The shake is 500ml of milk that needed a fridge you don't have and a stomach you don't want to fill before brunch.

In transit

The powder is a shaker, a scoop, a mess, and an explanation at TSA. A project, when you needed a moment.

Ours takes ten seconds. Twist, drink, done.

Founding pricing

Questions

The short version.

Why is it so small?
Small is the entire point. 24 grams of protein in 100ml is the densest protein format you can buy, which is why it fits in a pocket, clears airport security, and gets finished even on a low-appetite day. Getting that much protein into that little liquid is genuinely hard, and it's why this product hasn't existed until now.
When does Case One ship?
Case One is a limited, numbered first production run currently in development. The list hears exact dates first, and sharers get shipped first. That's the deal.
Is this a meal replacement or a diet drink?
Neither. It's the protein you were going to skip, back in your day. 99 calories, zero sugar, zero fat, no caffeine, no meal pretensions.
