💜Dear reader,

We keep noticing the same thing: the products that win aren't the ones with the biggest budgets, they're the ones that understand how people actually decide to buy, and where the behavioural science kicks in..

So every week we tear apart one of those decisions. It could be a shipping bar, a colour choice, or a pricing trick, and each issue we show you the psychology underneath it.

If you want the "why" behind the "why did they just buy that," you're in the right place.
