The Next Chapter of Lilu
Pumping should work for you, not against you.
Every pumping journey is different. Every drop counts. So does everything it takes to make it. Pumping has come a long way, but there is still so much room to make the experience more thoughtful, supportive, and built for real life. Lilu is creating what comes next—and inviting moms to help shape it.
The Massage Bra is retired. We're listening to moms about what should come next.

Every Journey Matters
No two pumping journeys look the same.
Some journeys are brief. Some last for months. Some involve exclusive pumping, occasional bottles, returning to work, building a milk stash, supplementing, or changing plans along the way. Better tools should adapt to real lives—not ask moms to adapt to them.
Built on Experience
Years of rethinking lactation support.
Lilu has explored how physical products, better data, and thoughtful design can make pumping and lactation support more human.

Our Story
Built with moms, from the very first sketch.
We’re Adriana and Sujay—engineers and product builders who met at Penn. After hundreds of conversations with pumping parents, we combined human-centered research, soft robotics, hardware, and software to create the Lilu Massage Bra.
We’ve never built Lilu alone. Over the years, moms who generously tested early prototypes and shared their experiences, along with our interns, colleagues, mentors, and partners, have rallied behind the vision and helped shape Lilu at every step.
Now, we’re applying everything we’ve learned to something new.
Women’s and maternal health deserve more than workarounds. They deserve ambitious technology designed for real bodies and real lives.
Built around women. Engineered for real life.
