Willow Pump

Willow is a wearable and hands free breast pump that fits inside your bra.

Willow is the femtech leader that changed the way women pump with the first ever quiet, all-in-one.

Willow was founded in 2014 by Naomi Kelman and John Chang. The company is based in Mountain View, California.

Willow is on a mission to bring joy to motherhood by solving problems with brilliant solutions, the Willow team came together to challenge the assumptions of 'what is' to 'what could be' for moms in the modern world.

Willow's patented technology mimics a baby's continuous suction, making it the only pump that can offer true spill-proof mobility. The company's life-changing breast pump discreetly tucks into a bra, without cords, dangling bottles or loud sucking noises — freeing moms up to pump wherever life takes them.


Willow is the only breast pump with the flexibility of pumping directly into both spill-proof Milk Bags and a reusable Container.


Willow is backed by NEA, Meritech Capital Partners, Lightstone Ventures and others. The company raised an additional $20M in it's Series B round on Dec 20, 2019. This new round brings Willow's total funding to around $100M to date.
