AG1

I tore AG1 down on the phone, where 90%+ of its traffic lands — and the page that does all the selling hides its best asset. The €87→€67 first-order stack sits a quarter of the way down a 16,000px scroll, behind a carousel that can't add to cart, with no sticky buy button to bring intent back.

Spacegoods

A vibrant, well-monetised store — strong brand, subscription-first buy box, and a cart that already upsells. The conversion gaps are ordering and hierarchy — what the first screen says, and how far the proof sits from the decision.
