Who we are

Rainmaker is a company specializing in product development that started in Korea in 2019, and is a startup that established a corporation in Manhattan, NY in 2022.

Daily use of paper filters and coffee beans added up and honestly the cost was surprisingly high. And a sparking thought came into our mind, “Why does delicious coffees have to use a paper filter?” Our ideas soon became a solid mission to design a brewer that brings a positive impact to the environment.

And now we are proud to call ourselves the pioneer of the world’s first stainless steel cup-shaped coffee brewer.
