“We can’t help it. We love cheese.”

- Ryan and Perumal

What started in 2014 with two guys, a big idea, and a shared passion for cheese, has quickly grown into a company on a mission to create a world of delicious animal-free dairy products. We thought: Why give up our favorite foods? There must be a better way. And so we brought together a diverse team of chefs, food developers, scientists, engineers, and marketers to achieve this goal.

Our Mission

To empower you to enjoy the dairy foods you love while making the world a kinder, greener place. Zero compromise required.


The name Perfect Day? As two scientists discovered, dairy cows who listen to soothing music like the Lou Reed song 'Perfect Day' are calmer, happier, and produce more milk.
