Category creators Willow and Oura fend off copycats

Category creators like Willow and Oura face a familiar dilemma: how to protect a market lead while rivals scramble to copy their innovations.

How Willow reinvented breast pumping

When Willow entered the market in 2014, most nursing mothers used bulky, corded pumps that required a seated position. The founder, Sarah O’Leary, described the old devices as “tied you down” and “inconvenient.”

Willow’s answer was a wearable pump that fits inside a bra, letting mothers move freely while expressing milk. The design quickly reshaped the segment. Within a decade, “wearable” has become a standard filter on insurance sites, and competitors such as Momcozy, Zomee and Spectra now offer similar products.

Willow still controls a large retail footprint—about 1,900 Target stores, 200 Kohl’s locations, and a recent launch in 1,600 Walmart outlets.

O’Leary says the brand’s advantage rests on “truly customer‑oriented, user‑focused innovation.” She points to the company’s clinical testing and a recent manual pump, Willow Wave, launched at 1,600 Walmart locations.

Oura’s rise in the health‑tracking ring market

Founded in Finland in 2013, Oura launched its first ring in 2015, a time when fitness trackers focused on steps. By emphasizing sleep monitoring and a discreet, jewelry‑like form factor, the company carved out a niche that competitors had overlooked.

Common tactics for defending a lead

Both Willow and Oura stress that solving an unmet need is only the first step. Continuous listening to customers, scaling distribution and safeguarding intellectual property are equally important.

Willow’s strategy includes a robust support team that offers video calls for troubleshooting. Oura relies on a feedback loop that informs software updates and hardware refinements.

Copycats can erode confidence, especially when they sell substandard products that lack FDA clearance. Willow’s CEO warned that a mother who purchases a cheap, non‑cleared pump on Amazon may experience motor failures and poor milk output, causing her to question the entire wearable‑pump concept.

In an effort to keep prices competitive, Willow leverages its scale to lower costs, and Oura expands its ecosystem with features like integration with the women’s health app Natural Cycles.

Innovation remains their best defense.
