Why Willow

Simple + Easy to Clean

Only a few parts to put together and two dishwasher-safe parts to clean for easy setup and fast cleanup.


Willow works quietly so you can go ahead and take that conference call without the mute button.


Our Willow App displays what is happening when you pump. See such things as milk volume, pumping time, and past pumping sessions.

Effective + Intuitive

Willow senses your let-down and automatically transitions into expression phase based on your body's own unique milk production and timing.

Don't Go It Alone
1:1 Coaching

Your Willow comes with personalized coaching (over text, call, or video chat) to help answer any questions and get you pumping smoothly. A pump as unique as Willow has a learning curve, but moms have told us that even one short coaching session has provided the guidance they need—saving a ton of time and effort.

"Once I got the hang of Willow, it felt like a weight lifted off my shoulders. I was almost ready to quit pumping, and finding Willow gave me the willpower to continue. This is a total game changer. I think it would allow women to continue pumping long after they would otherwise stop because of how inconvenient and intrusive other pumps were."

Colleen L. New Jersey

Toby S. California

"I got an email from a Willow Coach thanking me for joining Willow, and wanting to set up a phone call to make sure I understood how to use it and to answer any questions. All of that is incredibly user-friendly. It just shows that they really care about their customers."

Christine H. New York

Brenna H. California

"By the end of my third day with Willow, I couldn't imagine how I ever used to pump and care for little ones at the same time. It took me several sessions to get the alignment right."

Lauren W. New York

Sanne H. California

"Willow has been an amazingly empowering experience for me, really supporting my goal to breastfeed my baby for at least one year while having a demanding job. I can now proudly say I am managing to do both—work and breastfeed. If I had to pay for the pump, as well as the milk bags, I would regard that as an investment totally worthwhile."
