MARIA is redefining coffee with ultrasonic brewing – fast, consistent, and scalable, from cold brew and filter to hot and cold espresso.
Its patented technology removes skill and time barriers, while delivering exceptional flavour. With global media coverage and major manufacturer interest, MARIA is primed for licensing, rapid scaling, and production.

MARIA’s patented ultrasonic brewing system uses acoustic cavitation to extract exceptional cold brew and espresso coffee. Its system reduces brewing time, barista training, and storage needs while delivering superior flavour. It generates revenue through direct sales to cafés and roasters, and by licensing its technology to coffee-machine manufacturers for scalable integration.
