Meet our board of directors

Mark Tluszcz is the Chairman of K Health and web development platform Wix. He was the first investor in Skype, and just like how he helped Skype change how we communicate with our peers, he’s helping K change how we get health care. He’s the CEO and Co-Founder of Mangrove Capital Partners, a leading European early-stage investment firm, and lives in Luxembourg. 

Allon Bloch is the CEO and Co-Founder of K Health, and the CEO of Hydrogen Health, the joint venture between K, Anthem, and Blackstone Growth. His own frustration with the U.S. healthcare system inspired him to build the smartest global healthcare solution, in the palm of your hand. As a current board member of Wix, and former CEO of Wix and Co-Founder and CEO of Vroom, he’s brought together a diverse group of leaders and experts to help reach his goal of giving everyone access to better, affordable care to improve health outcomes.  

Antonio Gracias brings his experience as the lead independent director of Tesla and director of SpaceX to the board of K Health. His focus is on businesses that service something always in demand—like health care, cars, and pizza (he also invested in Little Caesar’s). He’s the CEO of Valor Equity in Chicago.   

Vivian Riefberg brings over 30 years of healthcare industry experience to K Health. She’s a board member at Johns Hopkins Medicine, PBS, and Signify Health (NYSE: SGFY) and the former co-leader of the health services practice at McKinsey & Company. She’s currently a Professor of Practice at the University of Virginia Darden School of Business and a Director Emeritus at McKinsey & Company. In addition to health care, she has a vested interest in women’s leadership.

Adam Singolda is the Co-Founder of K Health, as well as the CEO and Co-Founder of Taboola, the world’s leading content discovery and distribution platform. Like how K helps people answer their health care questions, Taboola helps people decide what to buy and where to go. Taboola is currently valued at $2.6 billion and looking to go public.   

Hans Tung has invested in Airbnb, Peloton, Slack, and more than a dozen other early stage startups now valued at $1B+. As Managing Partner at GGV investments, he brings a truly global and consumer-obsessed perspective from his time living and working in the Americas and Asia to the K Health board. 

Alex Zubillagais serves on the board of Wallapop, Lyst, letgo, and Simple Feast, and was an early investor in Spotify. Like how Spotify changed how we listen to music, Alex is helping us change how we manage our health care. He’s the Founder of 14W, a New York-based venture capital firm focused on consumer mobile, web, e-commerce, CPG, and media. 

Daniel Gulati knows how to grow consumer companies from the ground up. As the founding partner at Forecast Fund, he was an early investor in companies like Away and MealPal. He likes to work with founders who’ve solved a problem for themselves—and is loving working with K Health. 

Rajeev Ronanki is the SVP and Chief Digital Officer of Anthem, a health insurance provider in the U.S. that, like K Health, believes in the power of AI to better our healthcare system. He’s been part of the team working on Hydrogen Health, a joint venture between Anthem, K, and Blackstone Growth, which uses K’s AI to lower healthcare costs and improve patient care.  

Vivek Pattipati is a board observer at K Health and brings over a decade of experience working with startups focused on everything from cryptocurrencies to robotics.
