The Logic of Care
In 1961, a 37-year-old woman named Sylvia McLaughlin stood on the shore of San Francisco Bay and watched the water recede, not from the tide, but from the hands of men who called it progress. Every day, another truck dumped rubble into the blue. Bit by bit, the horizon drew closer.
Most people saw development. She saw disappearance.
So Sylvia gathered two friends, Kay Kerr and Esther Gulick, and together they did something no one had done before: they decided the Bay was worth saving.1 Their fight was never framed as economic policy or environmental infrastructure. It was framed as care, the kind of care that didn’t yet have a market value.
That act of preservation became Save the Bay, and with it, a quiet revolution began: the idea that what we care for is worth investing in.
For decades, capital treated women’s work and women’s health the same way, as sentimental, secondary, somehow outside the logic of growth. But that logic is starting to crack.
A Signal Wrapped in a Balance Sheet
Last week, when Blackstone and TPG announced their $18.3 billion acquisition of Hologic, the headlines called it a medtech deal. It wasn’t. It was a cultural signal wrapped in a balance sheet, a marker of how far the idea of care has travelled since Sylvia’s shoreline.
For the past two years, I’ve been tracing these inflection points; the moments when care becomes capital, and capital begins to change what we value. That journey has led to a book I’ll release early next year: The Billion Dollar Blindspot: Why Women’s Health Is the Investment Opportunity of Our Time.
It’s built from hundreds of conversations with founders, investors, and scientists who are reimagining women’s health as the next frontier of global healthcare innovation. Over the next few weeks, I’ll share some of their stories here as we move toward the book’s launch.
To all of you my dear readers who’ve been reading, sharing, and building this conversation alongside me, thank you. You’ve already been part of this story.

The Capital Correction
For years, women’s health sat in the margins of pitch decks labelled niche, emotional, unscalable. But if you look closer, Hologic’s diagnostics for women run on the same logic as infrastructure.
Screening. Imaging. Detection.
Predictable demand. Recurring revenue. Population-level reach.
Earlier this year, Cosette Pharmaceuticals paid $672 million for Mayne Pharma, offering a 37 percent premium for a portfolio built on women’s health and dermatology. It wasn’t philanthropy. It was pattern recognition.
This is what happens when capital markets finally start seeing women’s health not as empathy, but as economy. Investors didn’t wake up suddenly moral; they woke up to yield.
Diagnostics offer the holy grail in a high-rate world: stable cash flows, low volatility, and demographic inevitability.
We are at the inflection point where the other 51% of the population becomes a fixed income asset because of the quiet convergence of macroeconomics and biology.
The Consolidation Wave
That’s what makes the Blackstone–TPG move more than a medtech headline. It’s a structural signal and the start of a consolidation cycle that will define the next decade of women’s health. Capital is moving down the maturity curve.
Not into speculative innovation, but into ownership of established infrastructure; clinical platforms, diagnostic networks, and data systems with recurring revenue.
As early-stage innovation advances, we’re already seeing a bottleneck at the scale-and-infrastructure layer where large institutional investors step in to own what’s been built rather than fund what’s still being invented.
The logic is simple: once the science is proven, whoever owns the rails owns the future cash flow. And that’s why we’ll see more of these mega-deals; large funds consolidating the backbone of women’s health, turning what was once fragmented and underfunded into an investable category with industrial rhythm.
But progress has its paradoxes.
The same capital that once ignored women’s health now risks over-owning it. In finance, scarcity inflates value; in healthcare, visibility can do the same. And with visibility comes control.

The Real Asset: Data
Beneath every mammogram and molecular assay lies something more valuable than hardware: decades of biological data. That’s what Blackstone and TPG are really buying; not the machines, but the maps of women’s bodies, refined across millions of scans and test results.
This is the new infrastructure of care where pattern recognition becomes prediction, and prediction becomes profit. Data is the ultimate consolidator. It doesn’t just diagnose, it dictates. It determines which populations get seen, which treatments get built, and whose biology becomes the benchmark for innovation.
Data show deal value and funding in the broader medtech sector have declined (for example, by ~28% in healthcare & life sciences2), while investment interest in women’s health diagnostics is accelerating.3
That divergence tells you everything: capital is chasing not invention, but information. And that’s where the opportunity and the responsibility converge.
Because as women’s health becomes digitized, the same datasets that could unlock precision care could also entrench exclusion depending on who governs them. Ownership, then, is not just financial. It’s ethical.
The future of women’s health will be written by those who understand that data isn’t just an asset class. It’s a form of power.
The Future Logic of Care
Private equity doesn’t enter a market to explore it. It enters to optimize it.
The next phase of women’s health won’t be driven by discovery; it will be shaped by integration. Merging diagnostic assets, cutting duplication, and streamlining delivery into scalable, investor-ready platforms. That discipline will bring maturity to a sector long starved of capital structure.
But optimization has a bias: it rewards what’s measurable, repeatable, and billable. Menopause, pain, libido, autoimmune disorders, conditions still living in diagnostic ambiguity, risk being sidelined again, not for lack of need but for lack of margin.
We’ve seen this before.
In sectors such as fertility and elder-care, private equity has improved operational metrics and margins, but empirical studies raise concerns about patient experience, access, and continuity of care45.
The opportunity is extraordinary: to build end-to-end infrastructure that finally centers half the population. The danger is subtle: a system that optimizes around women rather than for them.
The firms that lead in this next phase will understand the new dual mandate of health investing: Return on Capital and Return on Care.
Because the smartest capital doesn’t just streamline; it stewards. And the next generation of returns will belong to those who remember that the body, like the Bay, is not something to be filled in. It’s something to be protected.
The Next Horizon
When Save the Bay began, no one imagined environmental preservation would evolve into a trillion-dollar industry. Carbon markets, renewable energy, ESG funds all grew from a fringe idea once dismissed as “women’s work.”
We are watching the same reframing unfold in healthcare. Women’s health is becoming infrastructure. The question now is whether investors will treat it with stewardship or extraction.
If you look a decade ahead, the next frontier won’t be who owns the diagnostics. It will be who prices the data.
When women’s biology becomes a tradable input in the global health economy, the most valuable company in healthcare may not make a drug or a device. It will make the algorithm that decides whose biology is worth predicting.
Blackstone and TPG didn’t just buy a company. They bought the future logic of care; institutionalized, capitalized, and finally visible. Because the market has caught up to what women always knew: Care isn’t a cost. It’s capital.

“The future of women’s health will be written by those who understand that data isn’t just an asset class. It’s a form of power.” How do we ensure that this power sits with the people whose data it is (also the women whose health it concerns, not only the men providing the capital)?
Absolutely essential analysis, Maryann. The shift from viewing women’s health as “niche” to seeing it as core infrastructure is overdue. Your point about data is critical—who controls it will shape not just profit, but access and innovation. The risk of optimization bias sidelining real women’s needs is real, especially for conditions that don’t fit neatly into billable categories.
As this consolidation wave builds, stewardship—not just financial engineering—has to be the priority. Ownership of women’s health data and platforms must mean accountability to the people whose lives are at stake, not just shareholders. Thank you for challenging us to think bigger, and for mapping the future logic of care so clearly.
