Lilu | Maternal Health and Breastpumping Technology
Something new is coming. The Lilu Beta Community is open.
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.
“The Lilu bra allowed me to finally feel that my breasts were empty after pumping and go longer between sessions without getting clogged ducts or mastitis. The massage was relaxing and super gentle. This is a must-try for any pumping mom—it saves your sanity and supply!”
Maria Garcia
“With my first son in the NICU, pumping was all I could do. I was scared to pump again with my second baby because of that experience. This bra makes a big difference: it is less painful, and I get 2–3 more ounces every time I use it.”
Shelby Wells
“As a new mom of twins, I am constantly looking for ways to increase my milk supply and pump more efficiently. I have tried different bras, flanges, supplements, and lactation massagers, and this bra has made the biggest difference.”
Alexandra Jorion
“I had an oversupply problem, and my ducts would clog and become extremely painful. Later, when I developed an undersupply problem, the Lilu bra was lifesaving again.”

Built on Experience

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.
