Ran Shaul

Ran Shaul is an Israeli entrepreneur and the co-founder and chief product officer of K Health, a New York-based clinical AI company that partners with major U.S. health systems to deliver AI-powered virtual primary and specialty care.^[1][15] K Health has raised more than $439 million across thirteen funding rounds and was valued at $900 million as of its July 2024 Series F.^[14][15]

Before K Health, Shaul founded Synergy, a data and CRM consultancy acquired by NESS Technologies in 2010, and co-founded Pursway, a social-graph marketing analytics company acquired by Interpublic Group in 2015.^[8][6] Across two decades, his career has followed a consistent thread from CRM data to behavioral analytics to clinical AI — a trajectory he has described as sitting "at the intersection of human behavior, analytics, and data."^[17]

Ran Shaul was born and raised in Tel Aviv, Israel, during the early years of what would become known as the country's "Startup Nation" technology ecosystem.^[8] He has cited the emergence of Israeli technology companies such as Amdocs as formative, describing how seeing Israeli entrepreneurs build globally significant companies inspired his own ambitions.^[8]

Shaul served as a lieutenant in the Israel Defense Forces from approximately 1992 to 1997, commanding a platoon of roughly 120 soldiers by age 21.^[8] He has credited the military with teaching him high-pressure decision-making and leadership under uncertainty.^[8] After completing his service, Shaul enrolled at Tel Aviv University, where he earned a Bachelor of Applied Science in Industrial Engineering.^[1]

Israel Defense Forces (1992–1997)

Shaul completed approximately five years of military service in the IDF, including mandatory conscription and an extended officer commitment. By age 21, he held the rank of lieutenant and was responsible for a platoon of approximately 120 soldiers.^[8] He has described the experience as foundational to his approach to leadership and strategy in business.^[8]

Opisoft (2000–2003)

After completing his degree at Tel Aviv University, Shaul joined Opisoft as a senior vice president.^[1] At Opisoft, he gained early exposure to data warehousing, data mining, natural language processing, and AI applications — technical domains that would define his subsequent career.^[8] The experience at Opisoft and other IT companies convinced Shaul he was ready to start his own venture.^[8]

Synergy (2003–2010)

In 2003, Shaul founded Synergy, a data science and CRM consultancy based in Israel.^[8] He has described the decision as driven by a readiness to take risk: he was unmarried, had no children, and felt confident from his corporate experience that he could build a company himself.^[8] Under his leadership as CEO, Synergy grew to more than 100 consultants serving enterprise clients on customer acquisition, predictive analytics, and anti-churn strategies.^[8] In 2010, Synergy was acquired by NESS Technologies (NASDAQ: NSTC), a publicly traded Israeli IT services firm. Shaul remained for approximately six months post-acquisition before departing.^[8]

Pursway (2005–2015)

While still running Synergy, Shaul co-founded Pursway in 2005, a social-graph marketing analytics company that used proprietary algorithms to identify influential consumers within social networks and map their impact on purchasing behavior.^[8][9] The company's technology analyzed transactional and behavioral data to build influence maps across more than 100 million North American consumers, enabling brands to target marketing spend toward individuals with outsized peer influence.^[9] Pursway raised $7.2 million in a Series B round in October 2013 led by Battery Ventures, bringing total funding to approximately $13–17 million.^[9][6]

To close enterprise deals with clients such as Bank of America, American Express, and Fidelity, Shaul relocated from Israel to the United States — an experience that taught him the necessity of physical presence in the U.S. market for B2B sales.^[8] In September 2015, Pursway was acquired by Interpublic Group (NYSE: IPG) for a reported $15–20 million.^[6][11]

IPG Mediabrands (2015–2016)

Following the Pursway acquisition, Shaul served as managing director at IPG Mediabrands, the media and data division of Interpublic Group, where he integrated Pursway's social-influence analytics into IPG's broader marketing platform.^[6][1]

Omnicom Media (2016)

Shaul briefly held the title of executive vice president of audience analytics at Omnicom Media around 2016.^[1] The exact nature and duration of this role — at a company that competes with IPG — is not fully documented in public sources. It may have been a short sequential engagement following his departure from IPG Mediabrands.

K Health (2016–present)

In 2016, Shaul co-founded K Health with Allon Bloch (CEO), Israel Roth (CTO), and Adam Singolda.^[14] The idea originated not from a healthcare background — none of the founders had one — but from a data-analytics perspective. Shaul and Bloch, who had met through mutual investors when Shaul consulted for Bloch's company Vroom, recognized that the universal frustration with online symptom-checking was fundamentally a data-modeling problem.^[8][13] Before writing product code, the team spent approximately a year in R&D studying how physicians reach diagnoses, concluding that clinical reasoning is highly analytical and could be replicated by machine learning.^[17]

The founders approached Israeli HMO Maccabi Healthcare Services, which had been digitizing physician records since 1993, and secured a licensing agreement for anonymized data covering 2.2 million patients across 25 years — including 400 million doctor-patient consultations, 500 million prescriptions, and over one billion lab results.^[13][14] From this data, K Health built a proprietary language model — effectively a transformer architecture — before the term was widely known in the industry.^[15] The company later added data from Mayo Clinic, incorporating 5.3 million anonymized patient charts and 1.2 million lab tests.^[14]

K Health launched publicly in January 2018 as a free AI-powered symptom checker and evolved into a B2B clinical AI platform.^[14] The company raised a $132 million Series E in January 2021 led by GGV Capital and Valor Equity Partners, reaching a peak valuation of approximately $1.5 billion.^[14][17] A $59 million round in July 2023 was characterized as a down round, followed by a $50 million equity raise in July 2024 at a $900 million valuation led by Claure Group.^[17][14] An additional $58.9 million Series G round in 2026 maintained the approximately $859 million valuation.^[18] Total funding has exceeded $439 million across thirteen-plus rounds.^[15]

As of 2026, K Health's clinical AI platform — branded PatientGPT — is embedded in the patient portals and EHR systems of more than ten major U.S. health systems, including Cedars-Sinai, Mayo Clinic, Hartford HealthCare, Mass General Brigham, Northwell Health, Penn Medicine, and Hackensack Meridian Health.^[15][19][17] The Cedars-Sinai Connect deployment increased primary care capacity by 15% and served 42,000 patients.^[15] By mid-2023, more than 10 million people had interacted with K Health's AI and 3.1 million had completed clinical visits across 48 states.^[14] The company reported $52 million in revenue for 2022 and employed approximately 400 people, split between New York and Tel Aviv.^[14][15] K Health has publicly indicated it is targeting an IPO by 2028–2029.^[18]

Hydrogen Health (2021–present)

In April 2021, K Health launched Hydrogen Health, a joint venture with Elevance Health (formerly Anthem) and Blackstone Growth, focused on delivering virtual primary care models for employers and insurers.^[14][23] Shaul has served as chief product officer of Hydrogen Health concurrently with his K Health role, overseeing product development for the enterprise-facing virtual care platform.^[23]

Shaul was born and raised in Tel Aviv and relocated to the United States — initially to Boston during the Pursway years, and later to the New York City metropolitan area, where he is currently based.^[8][1] He is the older brother of Israeli filmmaker Dror Shaul, director of the film Sweet Mud.^[8] Shaul has co-authored clinical research with physicians, including a 2025 article in HCPLive on AI performance in urgent care treatment recommendations.^[25]
