What a Business Really Does

🎬 Situation

Maya just quit her office job to open a coffee cart outside a busy train station. Her friends ask: "So how will you actually make money?"

She says "I'll sell coffee", but that's not quite the answer. To understand any business, from a coffee cart to Apple, you need one simple picture.

This is the value stick. Move the sliders and watch who gains what on every latte Maya sells.

Notice three things:

• When the price goes above what the customer would pay, the sale disappears and nobody gains.
• Moving the price only moves value between Maya and her customers.
• Raising the top (better coffee) or lowering the cost grows the total.

🏷️ Name it

Business schools call this the value stick, and it explains every business in the world:

• Value created = willingness to pay − cost. This is the size of the pie.
• Customer's gain = willingness to pay − price. This is why people buy.
• Profit = price − cost. This is the business's slice, the value it captures.

So the job of a business is to create value and capture some of it. Great companies do both: their products are worth far more to customers than they cost to make, and enough of that value comes back as profit to keep improving.

🖍️ Like you're five: you make a lemonade that your friend thinks is worth 5 stickers. It costs you 1 sticker of lemons. You trade it for 3 stickers. Your friend is happy (they "saved" 2), and you're happy (you earned 2). You both won, because the lemonade was worth more than the lemons.

Real life: some famous companies choose to give most of the value to customers. A warehouse store with rock-bottom prices keeps a thin slice per item but sells huge volumes, and customers keep coming back. A luxury brand does the opposite: it raises willingness to pay so high (through design, status and story) that a big slice is left over even at a high price.
