Inventing the product is the enjoyable part. What follows is the hard part: a first production run paid for up front, stock that ties up your cash, and a first hundred customers who have never heard of you. A product does not sell itself β what sells is the reason to buy yours instead of the one somebody already trusts.
There are 24 ideas here: private-label cosmetics and household goods, manufacturing from recycled material, personalised gifts, premium outdoor gear and products built around a story. Each gives the cost of the first run, the usual margin, the risks and a per-unit price calculator. Making things by hand to order is its own theme β this one is about a product that can be produced repeatedly and in quantity.
