The United States spends more on health care than any other high-income nation, yet our life expectancy is actually dropping. It’s a mathematical disaster. Most people look at the skyrocketing costs and the labyrinth of insurance codes and want to run the other way. Dr. Toyin Ajayi isn't most people. As the CEO and co-founder of Cityblock Health, she's betting that the absolute worst parts of our system—the inefficiencies, the neglect of poor communities, and the "politics of the broken"—are actually the greatest opportunities for innovation.
If you’ve ever tried to navigate Medicaid or seen a local clinic close down in a low-income neighborhood, you know the frustration. The system isn't just failing; it’s designed to ignore the very people who need help most. Ajayi argues that by focusing on these marginalized populations, we can actually fix the broader economic rot within American medicine. It’s a bold take. It’s also one that’s attracting billions in valuation and serious attention from policymakers.
The Business of Fixing What We Ignored
Most health tech startups chase the "worried well." They build slick apps for people with high-end employer insurance who want to track their sleep or get a vitamin drip. Cityblock does the opposite. They go after the "high-need, high-cost" individuals—people often juggling multiple chronic conditions, housing instability, and food insecurity.
In the traditional fee-for-service world, these patients are seen as liabilities. They miss appointments because they don't have a car. They end up in the ER because they couldn't afford their insulin. Each ER visit costs the system thousands. Cityblock’s model flips the script by using value-based care. They get paid to keep people healthy, not just to perform procedures. If they keep a patient out of the hospital by helping them find stable housing or a reliable pharmacy delivery, Cityblock wins financially. More importantly, the patient actually lives a better life.
This isn't charity. It's a calculated business move. When you look at the $4.5 trillion spent annually on U.S. health care, a massive chunk is wasted on preventable hospitalizations. By capturing that waste and turning it into preventive care, Ajayi is proving that you can build a unicorn company while serving the "unprofitable."
Why Politics Keep the System Expensive
You can't talk about health care without talking about the political machinery that keeps it stuck. Lobbying from massive hospital chains and pharmaceutical giants ensures that the status quo remains profitable for those at the top. We’ve built a "sick-care" system that rewards volume over value.
Ajayi is vocal about the fact that health is social. Your zip code is a better predictor of your lifespan than your genetic code. But our political systems are often too siloed to handle that. Housing policy is in one bucket, nutrition in another, and medical care in a third. Cityblock tries to bridge these gaps. They employ community health partners who might spend their day helping a member fill out a SNAP application or fixing a mold problem in an apartment.
It sounds simple, but it’s radical in a system that usually only pays for what happens inside the four walls of a doctor’s office. The politics of "broken" health care are often just the politics of convenience—it’s easier to keep paying for ER visits than it is to fix the underlying poverty that drives them. Ajayi’s insight is that the private sector can sometimes move faster than government bureaucracy to integrate these services, provided the financial incentives are aligned correctly.
The Data Behind the Disruption
To make this work, you need more than just good intentions. You need massive amounts of data. Cityblock uses a proprietary platform called Commons to track everything. They aren't just looking at blood pressure readings. They’re looking at social determinants.
What the Numbers Say
- Reduced ER Visits: Cityblock has reported significant drops in unnecessary emergency room usage among its members.
- Engagement Rates: Unlike traditional clinics that struggle to reach "hard-to-find" patients, Cityblock sees much higher engagement by meeting people where they are—literally in their homes or via text.
- Market Scale: Since its spin-off from Sidewalk Labs, the company has expanded across multiple states, including New York, Massachusetts, and North Carolina.
The data proves a point that many in Washington are finally starting to hear: if you invest in the social side of medicine, the medical costs take care of themselves. This is the "opportunity" Ajayi talks about. It’s the chance to take the most expensive, least efficient part of the American economy and finally make it work.
Breaking the Trust Deficit
Let’s be real. If you’re a person of color or someone living in poverty, you probably don't trust the medical system. History gives you plenty of reasons not to. This "trust deficit" is a huge barrier to care. You won't take the meds if you don't trust the person prescribing them.
Ajayi, a physician herself, understands this deeply. Cityblock’s workforce often reflects the communities they serve. They don't show up in white coats with a clip-board and a lecture. They show up as neighbors. This cultural competence isn't just a "nice to have" feature—it’s the engine of their clinical success.
Most tech-driven health companies think they can solve everything with an algorithm. Cityblock uses the algorithm to find the people, but they use human relationships to heal them. It’s a mix of high-tech and "high-touch" that most big hospital systems just can't replicate. They’re too busy worrying about their billing cycles to worry about whether a patient has a working refrigerator for their meds.
What This Means for the Future of Medicare and Medicaid
As the U.S. population ages and the wealth gap widens, the pressure on Medicaid and Medicare is going to become unbearable. The current trajectory is unsustainable. We’re going to see more "Cityblock-style" models because we simply don't have a choice.
States are already looking for ways to cap their spending. They're increasingly turning to private companies that are willing to take on the "risk" of these populations. If Ajayi’s model continues to scale, it could provide a blueprint for how we handle the "graying of America" without bankrupting the treasury. It’s about moving from a system of "doing things to people" to "doing things for people."
Take Action on Your Own Terms
You don't have to be a CEO to start shifting the way we think about health and value. Whether you’re a provider, a patient, or an investor, the shift toward value-based care is the most important trend in the industry right now.
If you're a healthcare professional, look into certifications or roles within value-based care organizations. The demand for people who understand the intersection of social work and medicine is exploding. If you're an advocate, push for local policies that integrate housing and health data.
Most importantly, stop looking at the "broken" parts of American health care as a lost cause. They are exactly where the most significant, and most profitable, changes are happening right now. Don't wait for a political savior to fix the system. The people building the next generation of health care are already doing it from the ground up.
