Knock Knock is a maker of products that bring wit, heart, productivity (and occasional light profanity) to everyday life. Our pads, planners, journals, and books help people accomplish their goals, express their feelings, and laugh at the absurdity of modern existence.

We live by (at least) two mottos: “We Put the Fun in Functional” and “Make a List—You’ll Feel Better.” We consider list-making and laughter to be essential forms of self-care. (And, obvs, we love mottos.)

Knock Knock was founded in 2002 by Jen Bilik, and in 2018 we joined forces with Em & Friends (formerly known as Emily McDowell & Friends).  In 2022 our small-but-mighty team was thrilled to become a part of the Union Square & Co. family. We’re super-excited about what’s to come. (Hint: it’ll probably involve paper and some sweary words.)
