Lava Sunder Corner Health is the story of a founder who spent her twenties building things far outside healthcare, real estate strategy, urban mobility, management consulting, before turning that operational range toward one of the industry’s most overlooked opportunities.
Sunder is the co-founder and CEO of Corner Health, a Los Angeles startup that gives nurse practitioners the billing, insurance, and AI-powered operational infrastructure they need to launch and run their own independent primary care practices.
In July 2026, Corner Health announced $32.5 million in combined seed and Series A funding, led by Oak HC/FT, on the back of a network that has already grown to more than 70 provider-owned practices. Here is how a former McKinsey consultant and a former venture investor built one of healthcare tech’s more quietly compelling bets on human-led care.
Lava Sunder Corner Health: Who Is She?
Lava Sunder is the co-founder and CEO of Corner Health, according to her LinkedIn profile. She holds a Bachelor of Science from Duke University, where she served as president of Duke Student Government, an early signal of the leadership range she would later bring to building a company from scratch.
Sunder has traced her interest in independent practice ownership to her own childhood. “I grew up watching my mom run her own private practice, and I saw firsthand how powerful it is when a clinician owns the relationship with their patient,” she has said. That personal thread runs directly through Corner Health’s entire business model: rebuilding the conditions that let a clinician own that relationship again.
From Duke Student Government to McKinsey to Culdesac
Sunder’s career before Corner Health moved through management consulting, real estate, and urban mobility, not healthcare. She joined McKinsey & Company as a business analyst in 2016, was promoted to engagement manager by 2018, and spent nearly three years advising organizations on strategy and operations.
In 2019, Sunder joined the founding team of Culdesac, the car-free housing development startup, in a business operations role, later becoming general manager of Culdesac’s flagship Tempe, Arizona development through March 2022. It was at Culdesac that Sunder first worked alongside Anne Gifford, her future Corner Health co-founder. Gifford’s own path ran through Barclays, where she worked as an investment banking analyst, and Tusk Venture Partners, where she spent two years as an investor before also joining Culdesac. That shared operating experience, building an entirely new kind of community from the ground up, became the direct template for building an entirely new kind of primary care network.
The Problem Corner Health Set Out to Solve
More than 100 million Americans lack access to a primary care provider, even as healthcare has spent decades pushing clinicians into larger and larger hospital systems, often at the expense of time spent with patients, according to Corner Health’s own funding materials. Nurse practitioners, a workforce that is roughly 77% women, are increasingly being granted full practice authority, the legal ability to operate independently of a supervising physician, in a growing number of U.S. states, currently 27.
Despite that regulatory shift, most nurse practitioners lack the operational infrastructure, billing systems, insurance credentialing, and administrative support, needed to actually start and run their own practice. Sunder and Gifford’s core insight was that 78% of nurse practitioners say they want to start their own business, according to data cited in Corner Health’s Series A announcement, but the vast majority never do, simply because the operational barriers are too high for one clinician to clear alone.
Building Corner Health: Team, Product, and Cora
Lava Sunder Corner Health was co-founded with Anne Gifford in January 2024. The company’s core product, Cora, is an AI-native operating system that automates the full spectrum of running a brick-and-mortar primary care practice, including scheduling, patient communication, billing, lab orders, referrals, and prior authorizations.
Rather than positioning AI as a replacement for clinician time, Corner Health uses Cora specifically to free that time up. Gifford has drawn a sharp contrast with how most of the healthcare industry currently uses AI. “The dominant use of AI in healthcare today is helping clinicians move faster and see more patients,” she said in the company’s funding announcement. “We’re using AI to create the opposite outcome. Our providers can see fewer patients, spend two to three times more time with each one, and still build thriving independent practices.” According to the company, Cora’s automation is effective enough that roughly 90% of Corner Health clinics operate with no additional administrative staff at all.
Inside Corner Health’s $32.5 Million in Funding
Corner Health has raised $32.5 million in total funding: $7.5 million in earlier seed and pre-seed rounds, followed by a $25 million Series A announced on July 9, 2026. The Series A was led by Oak HC/FT, a healthcare and fintech-focused investment firm managing more than $7 billion in assets, with continued participation from existing investors First Round Capital and Zigg Capital, alongside Homebrew, Pathlight Ventures, Wischoff Ventures, and Go Global Ventures.
The company says it will use the new capital to expand its internal team, deepen its Cora technology platform, and launch its primary care network in additional U.S. states beyond its current footprint in Arizona and Washington.
Customers and Traction: 70+ Practices and 35,000+ Patient Visits
Corner Health has built a network of more than 70 provider-owned primary care practices, making it, by the company’s own account, the fastest-growing primary care network in both Arizona and Washington. The network has enabled more than 35,000 patient visits over the past year, a substantial volume for a company that only launched in January 2024 and, as of mid-2026, employs around a dozen people internally.
The company also reports that nearly 90% of patients trust their provider more than other medical sources, and that repeat visit rates run more than twice the national average. With more time available per visit, Corner Health says more than 40% of appointments now include routine specialist-adjacent services, such as pap smears, skin procedures, and joint or injury care, reducing the need for separate referrals.
The Investors Backing Lava Sunder
Oak HC/FT’s decision to lead Corner Health’s Series A carries particular weight given the firm’s specific healthcare focus. Annie Lamont, a founding partner at Oak HC/FT, has reportedly tracked the regulatory shift toward full practice authority for nurse practitioners for more than a decade, giving the firm’s investment a depth of category conviction that goes beyond a typical growth-stage healthcare bet.
The round’s broader investor base, spanning First Round Capital, Homebrew, Zigg Capital, Pathlight Ventures, Wischoff Ventures, and Go Global Ventures, reflects continued confidence from Corner Health’s earliest backers alongside meaningful new participation, a pattern that typically signals strong internal traction data rather than just an attractive pitch.
Corner Health’s Position in the Healthcare AI Race
Corner Health enters a healthcare AI landscape where most companies are optimizing for clinician throughput, helping providers see more patients faster within existing large health systems. Corner Health has deliberately positioned itself in the opposite direction, using AI to let independent clinicians see fewer patients with more time each, while remaining financially viable outside a large hospital system.
That contrarian positioning, betting that AI’s real leverage in healthcare is giving time back to clinicians rather than extracting more output from them, distinguishes Corner Health from much of the AI-in-healthcare funding wave, and appears to be resonating specifically with nurse practitioners frustrated by administrative burden inside larger systems.
Leadership Style and What’s Next for Corner Health
Sunder’s leadership approach draws directly on her Culdesac experience: building the physical and operational infrastructure for an entirely new model of a familiar category, whether that category is housing or primary care. Gifford has emphasized that Corner Health’s technology exists specifically to reduce paperwork and operational burden so clinicians can spend more time with patients, a framing that keeps the company’s AI strategy tightly scoped to a single, measurable outcome.
With fresh Series A capital, Corner Health’s near-term roadmap centers on expanding its provider network into new states beyond Arizona and Washington, growing its internal team, and continuing to refine Cora as the operating layer beneath a larger share of America’s independent primary care practices.
Lessons for Entrepreneurs From Lava Sunder’s Journey
Sunder’s path offers a few clear lessons for founders building outside their own professional background. First, her personal connection to the problem, watching her mother run an independent practice, gave Corner Health’s mission an authenticity that purely market-driven healthcare startups often lack. Second, reuniting with Gifford, a colleague from Culdesac rather than a healthcare-industry contact, shows that shared operational experience building something ambitious from scratch can matter more to a founding partnership than shared domain expertise. Third, Corner Health’s decision to measure success by patient trust and provider retention, not just visit volume, gave the company a clearer story to tell healthcare-focused investors like Oak HC/FT than a pure growth metric would have.
