Eat Your Own Dogfood

"Eating your own dog food" is the practice of using your own products or services for internal operations. This can be a way to test your products in anger and gain real-world insights. Dogfooding also acts as quality control, and can eventually serve as testimonial advertising. Once in the market, dogfooding demonstrates confidence and belief in your company.

The origin is attributed to a Microsoft email in the 1980s, though it's worth mentioning that in the 1970s there was an advertisement for Alpo Dog food where a paid actor said he fed Alpo to his own dogs.
