The VC That Bets on the Boring, Broken Industries Everyone Else Skips
Two operators who helped build Oscar Health left to fund the unglamorous machinery of insurance, supply chains and climate. Their pitch to founders is simple: the hardest markets are the biggest ones.
Kristen Prestano Is Teaching Health Insurance to Talk Like a Person
How a communications lifer became the marketing chief at one of health insurance's most watched companies, and why she keeps betting that clear beats clever.
Oscar Health
Oscar Health began with a friendly app and an unfriendly problem: American health insurance. Fourteen years later, its bigger bet is that the individual market can become the operating system for how people buy care.
Elliott Green
Elliott Green is the co-founder and CEO of Dandelion Health, a New York-based real-world data and clinical AI platform building multimodal, longitudinal datasets from a consortium of non-academic health systems. A former founding member of Oscar Health with a finance background, Green launched Dandelion in 2020 to give life science companies and AI developers unbiased, clinical-grade data - including the images, waveforms, and notes that make up most of medicine but are rarely used. The company closed a $14M Series A in 2026 and has launched a free AI validation service and a GLP-1 data library aimed at bringing precision medicine to cardiometabolic disease.
Sahir Jaggi
Sahir Jaggi is the founder and CEO of Forus, an AI-powered network (formerly known as Tandem) that automates the paperwork sitting between a doctor's prescription and a patient actually getting the drug. Forus emerged from stealth in May 2026 with $160M in funding at a $1B valuation from Thrive Capital, General Catalyst, and Accel. Before Forus, Jaggi spent six years as a product leader at Oscar Health after studying biomedical engineering and computer science at Columbia.
Nick Reber
Nick Reber is the founder and CEO of Garner Health, a New York based health tech company that mines more than 60 billion medical claims records to find the highest-performing doctors and pays patients to choose them. A former Bridgewater Associates partner and Oscar Health leader, Reber turned a quantitative investing playbook on the messiest market in America, building a business that helps employers cut benefits costs without changing plans or networks. In 2026 Garner raised $100 million in Series E funding at a reported $2.74 billion valuation.
Anshul Rathi
Anshul Rathi is the founder and CEO of CertifyOS (Certify), a New York-based healthcare provider data platform that credentials clinicians in under two minutes using six data elements instead of 40-page forms. An engineer by training, he spent roughly six years as one of Oscar Health's earliest employees building its provider network and data infrastructure before leaving to attack the same problem industry-wide. CertifyOS takes an API-first, data-first, automation-first approach to making provider data a single source of truth across U.S. healthcare. The company raised a $40M Series B in June 2025, bringing total funding to about $69M.
Kevin Nazemi
Kevin Nazemi is the co-founder and CEO of Charlie, a Los Angeles fintech building banking specifically for Americans aged 62 and older. After co-founding the health insurance disruptor Oscar Health and later the retiree health platform Renew Health, he turned to a market almost everyone in fintech ignored: seniors collecting Social Security. Charlie launched nationwide in May 2023 with faster access to Social Security checks, no monthly fees, competitive yields, and fraud safeguards built for a generation that loses an estimated $36 billion a year to financial scams.
Meghan Joyce
Meghan Verena Joyce is the co-founder and CEO of Duckbill, a Boston startup that pairs AI with human experts to act as an executive assistant for your personal life - booking appointments, filing claims, and clearing the to-do list. Before founding Duckbill in 2022, she ran Uber's biggest East Coast markets, served as COO and EVP of Platform at Oscar Health, and advised the U.S. Treasury during the recession. She has raised $33 million for Duckbill, led by Forerunner Ventures, and sits on the boards of The Boston Beer Company and Guardant Health.
Vijay Kedar
Vijay Kedar is the co-founder and CEO of Tomorrow Health, a New York healthtech company rebuilding how home-based care is ordered, delivered, and paid for. A Goldman Sachs private-equity alum and early Oscar Health operator who launched its Texas market, Kedar started Tomorrow Health after spending six frustrating weeks trying to coordinate home medical equipment for his mother during her cancer treatment. The company has raised roughly $92.5M from backers including Andreessen Horowitz, BOND, Obvious Ventures, and Sound Ventures, partnering with health plans and providers to connect a fragmented home-care supply chain.
Josh Kushner
Josh Kushner is the founder and managing partner of Thrive Capital, a New York-based venture firm he started at age 24 with $5 million and has since grown to $50+ billion in AUM across 10 funds. He made one of the most consequential single bets in VC history by providing the only term sheet OpenAI received in 2022 at a $29 billion valuation. Co-founder of Oscar Health and Cadre, minority owner of the Miami Heat and San Francisco Giants, and husband of supermodel and media entrepreneur Karlie Kloss, Kushner operates from the Puck Building in Manhattan where his apartment and office share the same address. Known for his low-key demeanor, obsessive work ethic, and a hiring process that famously takes eight months.
