Our Team



At Lilu, we’re on a mission to redefine every mother’s breastfeeding and pumping journey so the joy of motherhood isn’t overshadowed by pain and discomfort, and is instead enriched with seamless, integrated care.

The Problem: Breast Pumping is Painful 

Why Breastfeed?

  • A breastfed child is at a much lower risk of obesity, diabetes, and infections
  • Breastfeeding is also associated with cognitive benefits, with studies showing higher IQ among exclusively breastfed children
  • Breastfeeding even lowers the risk of certain kinds of cancers in moms

However, moms still need to rely on antiquated breast pumping technology that hasn’t seen disruption in decades. 

The result? 

Over 75% of moms stop breastfeeding within the first 6 months which is well below WHO’s recommendation of 2 years. 

Moms have to deal with bottles, tubes and cables; they’re eternally multitasking while breastfeeding 5-6 times a day. 

The #1 reason why so many moms quit breastfeeding is because they find pumping too difficult, time-consuming, and painful.

This is where Lilu comes in. 

The Solution: Smart, Tech-Enabled Products Designed to Make Breastfeeding Comfortable, Efficient, and Pain-Free 

Our Omni Breast Pump and MilkSense systems are designed by women, backed by science, rigorously tested, and enthusiastically endorsed by over 2,500 moms and over 300 lactation experts.

Designed as complementary products:

  1. Omni Breast Pump System increases breast milk output with less pain and discomfort
  2. The MilkSense Bra + App unlocks powerful lactation insights to optimize breastfeeding and pumping routines


We’re Adriana C. Vázquez Ortiz and Sujay Suresh Kumar, engineers from MIT and Penn and the founders of Lilu. We hail from Mexico and India respectively and we met during our graduate programs at UPenn where we were labmates working on creative robotics projects together. 

Having seen many of our friends and colleagues struggle and feel disappointed with breast pump tech, we set out to learn more about the challenges of breastfeeding. After spending hundreds of hours in research, speaking with hundreds of moms in person and surveying thousands more, we discovered several prominent pain points with breastfeeding and breast pumping. We were appalled to see that breast pump tech was severely outdated. As engineers, product designers, and future parents ourselves, this was not acceptable to us. 

Motherhood is special, but it isn't always easy.

In fact, motherhood can be stressful, exhausting, painful, and confusing. 

Given the enormous health benefits for baby and mom, the choice to breastfeed seems simple, but it’s not. The WHO recommends that a child be breastfed for 2 years[1]. However, less than 25% of infants are exclusively breastfed for 6 months[2].

These numbers might be staggering, but they’re not surprising. 70% of moms need to go back to work 6-8 weeks postpartum. When they are away from their babies, they have to rely on outdated, inefficient breast pumps to continue to produce milk, and constantly worry about whether or not they are producing enough. Research shows that over 95% of breastfeeding moms use breast pumps during their lactation journey, during which they confront a number of challenges[3].

As engineers, product designers, and future parents ourselves, this was not acceptable to us. 

That’s why we became deeply passionate about making life easier for new moms by creating the products of tomorrow. 

Omni Breast Pump System: Mom’s Breast Friend 

Omni is the ultimate wearable breast pump that integrates our patented breast massage technology, designed to fit seamlessly into any nursing bra, to help moms pump up to 55% more milk! 

Tested with hundreds of moms during thousands of pumping sessions, and now trusted by over 2,500 moms in their breastfeeding journey, our patented massage technology is proven to be highly effective. Not only does our massage technology increase moms' milk production by 30-55%, it also reduces pumping time, pain, and risk of common infections like mastitis.


  • Won the Philadelphia Innovation of the Year award in 2019
  • Raised $750k in grants, prizes and early stage venture capital funding
  • Backed by Dreamit, Penn Center for Innovation, won multiple awards and accolades including a prize by Philips Health, among others
  • Shipped 2.5k+ units of inaugural product through D2C and wholesale.
  • Built relationships with 300+ lactation experts
  • Received top press coverage including Mashable, Philly Citizen, WIRED, sheKnows

Many moms who were about to quit breastfeeding, said the Lilu Massager + Bra is what enabled them to continue to breastfeed their babies and it even helped some moms relactate.

Having achieved technical validation and early product market fit through the beta product, the Lilu Massager + Bra, we are now ready to evolve. With a solid understanding of potential blockers to scale, we used a robust, customer-inclusive framework to design the most viable product possible. This led us to combine our massage tech with a wearable, hands-free breast pump to create the Omni Breast Pump. 

The Omni is ready to launch Q3 2024 and we know that moms want this product. We vetted customer demand for the Omni through validation tests which showed 15-20x improved acquisition costs (CAC) compared to the beta product. 

From rapid user adoption, glowing reviews, and the grants and awards received, we know our massage innovation offers major improvements to the outdated industry. The Lilu Massager + Bra proved that with the right technology, moms can pump smarter, not harder — and the Omni Breast Pump will make it even easier.

Milksense Bra + App: A GenAI-Powered Lactation Coach in Your Pocket

The new and groundbreaking MilkSense Bra + App is the first technology to provide real-time tracking of breastmilk supply while also caring for the overall physical and mental health of moms  – since they can’t take care of their baby if they don’t first take care of their own selves.

As moms feed their baby or pump, the cutting edge sensors embedded in our bra collect information about their breast milk production, expression, breathing, stress levels, movement, and sleep to provide them with holistic insights about their lactation via our mobile app.

After a few sessions, MilkSense can provide precise estimations of a baby's milk consumption during breastfeeding for a full picture of their feeding. It’s designed to help moms understand their breast milk production, visualize trends, and learn what tools and tweaks work to make lactation easier. The app also features an AI Chatbot for expert guidance to further support Lilu moms.

More importantly, MilkSense breaks the cycle of overwhelm, isolation, and anxiety, giving moms a companion to support their personal lactation journey. It’s a major step toward helping the mental health of millions of new moms around the world.

The MilkSense Bra is ready to launch in 2025; we are currently rolling out the beta version of the App with the full scale launch planned for Q1 2024.

Underserved Market

We’ve come a long way since our inception in 2017 and only $1.3M in dilutive funding from investors. Imagine the mountains we can scale with this raise. 


Both Omni and MilkSense have strong unit economics in the D2C and wholesale spheres.

The Lactation Insights App offers a freemium model with future opportunities to provide additional value-added services to our customers, allowing them to choose the level of support they need on their journey.

Looking into the future, the femtech industry has shown a precedent for lucrative exits in the maternal health space. Innovative mom tech companies have been scaling rapidly; pump companies like Elvie and Willow have raised over $150M and Maven recently became a unicorn. Yet many problems with maternal health, especially when it comes to breast pumping still remain unaddressed.

With our comprehensive product line, strong unit economics and an omni-channel strategy, we are well poised for growth.
