Why Health Systems Partner With Midwife-Led Maternity Startups y Keep Shutting Down

What Hospital CFOs Buy When They Partner With A Maternity Startup

Health systems are buying capacity they cannot staff, at a cost structure they cannot match, without hiring obstetricians who do not exist. Sharma has run this sale often enough to describe the buying chain precisely. A women’s health service-line leader builds the case, then carries it to a chief growth officer, a chief financial officer, or both.

The question on the table is not complicated. “Do we build or do we partner?” Sharma said. Increasingly, the answer comes back “partner.”

Stark law leaves three compliant routes, she explained: a clinically integrated network, a joint venture, or a professional services agreement paired with a management services agreement. UCSF chose the network, which lets Millie bill under the health system’s payer rates and work inside a shared record. Millie fronts the clinic buildout and earns it back as volume climbs.

Leanne Pashvok, chief operating officer at UCSF, framed the appeal around continuity rather than cost. Millie “brings a model of maternity care that is deeply focused on the patient while also recognizing the importance of being connected to a broader clinical system,” she said.

The Service Line Hospitals Value Most And Model Least

Birth is usually a family’s first serious encounter with a health system, and the relationship tends to hold. Patients stay for gynecology, return for a second pregnancy, establish pediatrics for the child, and eventually route the family through the same doors.

Hospital executives understand this. Sharma calls it the quiet reason maternity survives on the org chart at all, since the same space and staff would earn more elsewhere. Systems keep investing anyway, she observed, even though “they would probably make more money doing orthopedic surgery or cardiovascular.”

So do her partners price maternity for that long tail, or still treat it as a standalone cost center? Sharma’s answer was unexpectedly blunt. “We actually do not model all of that out,” Sharma said of Millie’s program economics, which run on the pregnancy episode plus a little adjacent gynecology.

That is a peculiar blind spot in an industry that measures everything. Oula, which runs a comparable model with Mount Sinai West and Novant Health, puts the number in front of hospital executives directly: 74% of women return to the system where they gave birth. If the funnel is real and nobody counts it, these partnerships are being priced on the smaller half of what they deliver.

Why The Savings Show Up In NICU Days And Not C-Sections

Sharma does have a number for the half she can measure. Millie tracks roughly 12% to 14% positive return on investment for payers on a risk-adjusted basis, she said, and has done so since the company’s earliest cohorts.

The source of that return is not what the category advertises. Nearly every maternity startup leads with its cesarean rate. Sharma argues the money is not there, because payment for vaginal and cesarean birth has been largely flattened. The savings live in preterm births and the neonatal intensive care stays that follow.

Millie reports about 30% better NTSV cesarean rates and 67% better preterm birth rates against national benchmarks, figures the company gathers itself and that no outside party has audited. Sharma says they have held or improved as the patient population grew. Asked whether any of it has been peer reviewed, she did not hedge: “Not yet, but we’re working on that.”

Is The OB Shortage Really A Utilization Problem

The obvious objection is that a hospital could hire midwives and skip the middle layer. Sharma’s answer reframes the shortage itself.

There is “too much noise about provider shortages and not enough noise about the fact that we utilize them badly,” Sharma noted. Her hardest engineering problem is not clinical but logistical: fitting new patients, returning patients, ongoing gynecology, and round-the-clock labor coverage onto one grid. She described the exercise as trying to “solve Tetris.”

The payoff is that Millie runs with a smaller team than a hospital would assign to the same volume, which is what her partners notice. “They see us do things that they couldn’t do themselves,” she said.

Underneath sits a workforce design argument. Almost nobody wants a full-time clinical schedule anymore, so Millie assembles half-time roles from one clinic day plus one 12-hour labor and delivery shift—20 hours a week, built for a clinician raising young children. A typical program handles about 40 births a month at full ramp, freeing hospital obstetricians for the complicated cases.

Where The Model Goes Next And What Could Stop It

Medicaid-heavy markets seem like they should be off the table. Sharma says payer mix barely enters the decision. She looks for three conditions at once: a health system partner with open capacity, enough births to keep a 24/7 operation staffed, and midwives willing to live there. California’s Central Valley clears that bar despite heavy Medicaid, because obstetric groups have retreated to gynecologic surgery and midwives can afford the rent.

The contrast with the category’s biggest name is instructive. Pomelo Care sells through payers and employers, covers more than 25 million lives, and raised $92 million in January at a $1.7 billion valuation. Millie has raised roughly $19 million. Sharma does not dispute Pomelo’s model so much as bound it, noting that “there’s only so much you can do virtually” when claims data reaches payers on a lag.

Emma Silverman, a partner at TMV, which co-led Millie’s $12 million Series A, put the bet plainly, the company has “rebuilt the care model itself, with technology at the core.” That round drew Pivotal Ventures and the March of Dimes Innovation Fund alongside it.

Whether it scales may turn less on technology than on arithmetic nobody is running yet. Health systems are buying maternity capacity at episode prices while quietly counting on decades of family loyalty they never write down.

The first chief financial officer who puts that second number in the model will change what these deals are worth.
