Real means a physical product where the consumer knows they have to pay upfront for the good. It really can be anything provided there’s a market.

Locate a nice size consumer market where they hasn’t been much innovation and the consumer is passionate. Then run low-cost tests.

Examples: - Stance with socks - Curves with women’s gyms - There are a ton of examples but what as engineers you want is a good that can be sold via the internet
