Willow Innovations, the Mountain View, California company that makes wearable breast pumps, has acquired Swehl, a Los Angeles breastfeeding education and community startup, and Momtech, the company behind the mõmi infant feeding technology. Willow announced both deals on October 27, 2026.
Willow did not disclose the price of either acquisition and declined to share terms when asked by MedCity News. Swehl co-founders Betsy Riley and Elizabeth Myer are joining Willow, while Momtech's Hal Eason will stay on as a strategic adviser.
Alongside the deals, Willow launched Willow World, a hub for breastfeeding education and community. Swehl's programming will form the core of the new hub, according to the company's announcement.
What Swehl built
Riley and Myer met through a mothers' group during the Covid-19 pandemic, after both had become new parents, according to a profile published by New York University, where both studied. They have said they found breastfeeding resources scattered, confusing and out of date, and set out to build something more practical for new parents.
Swehl was founded in 2021 and is based in Los Angeles, according to CB Insights. It launched publicly in March 2023, when it announced a pre-seed round of $1.1 million, Femtech Insider reported at the time.
At launch the company offered small peer support groups called Talk Circles, which matched up to eight parents at a similar stage, and access to Motherboard, a group of doctors, doulas and lactation experts. It also sold physical products, including latch kits and nipple support items. Before launch it ran a beta program called Founding Families with Cedars-Sinai, in which expectant parents who had not met before began gathering with their babies in Los Angeles parks, the NYU profile said.
Willow's release describes Swehl as a community-first breastfeeding company. The programming moving into Willow World includes Hot Moms Walks and a library of more than 80 breastfeeding education videos. A Mom Coach program that connects parents with credentialed lactation experts continues alongside it.
“These acquisitions help us expand beyond pumping into a more connected postpartum experience.”
Momtech and the mõmi bottle
Momtech, the second company in the deal, is based in North Carolina and sells under the mõmi brand, according to FutureFemHealth. Its patented feeding technology is designed to copy the mechanics of breastfeeding more closely than a standard bottle and to help babies move between breast and bottle, the release said.
On its brand page on Thingtesting, mõmi lists its home as Matthews, North Carolina, and says it develops and sells baby products that replicate natural nursing. The company claims its nipple design reduces nipple confusion and bottle refusal.
Willow and the outlets that covered the deal gave few other details about Momtech, including its headcount, revenue or the investors behind it. Hal Eason of mõmi will remain as a strategic adviser to Willow.
Why Willow is buying
Willow was founded in 2014 and has built its business on wearable pumps that fit inside a bra. It also sells accessories such as a breast milk cooler and runs an app with maternal care and wellness services, MedCity News reported. Dealroom lists the company as having raised about $147 million.
Chief executive Carolin Archibald said the two deals were meant to broaden what Willow offers. "We acquired Swehl and Momtech because each brings something that complements what Willow has built," she told MedCity News by email. She said Swehl had changed how brands reach mothers through community, education and conversation, and that Momtech's technology would widen the ways Willow supports families.
Archibald described the maternal health market as fragmented, with mothers moving between separate products, platforms and resources. "These acquisitions help us expand beyond pumping into a more connected postpartum experience," she said, adding that Willow plans to keep looking for further opportunities.
A string of deals
The two acquisitions follow Willow's 2025 purchase of Elvie, a UK women's health company that makes wearable breast pumps and pelvic floor trainers. Willow said that deal widened its international reach and added expertise in breastfeeding and pelvic floor products.
Willow has also signed a partnership with Lactamo, an Australian maternal health company, to bring Lactamo's breastfeeding aid, a medical device, to the US market. The company says the combination of acquisitions and partnerships is intended to cover feeding, recovery, education, community and maternal mental health, with Willow World as the place where mothers learn and connect.
Neither Swehl nor Momtech has said whether its own brand or products will continue to be sold separately. Willow's announcement focused on folding Swehl's content into Willow World and adding mõmi's feeding technology to its range, and it gave no timeline for further changes.
