LifeX

Amol Sarva is a founding partner of LifeX Ventures, bringing a background in cognitive science and company building to investing at the intersection of AI and health.

He studied at Columbia University and earned his PhD at Stanford, where his research examined modularity in cognitive science. Questions about how intelligence works have remained a thread through his work as an entrepreneur, investor, and teacher.

Amol was part of the founding team of Virgin Mobile USA, which went public in 2007, and founded Peek, an early mobile device company. Those ventures placed him in the development of consumer technology as mobile connectivity became part of everyday life.

His later work includes Halo Neuroscience, Knotable, and Knotel, spanning neurotechnology, collaboration software, and flexible workspace. Across these businesses, he has worked through product development, fundraising, organizational growth, and major corporate transitions.

Alongside investing, Amol teaches at Columbia and has helped build communities of entrepreneurs, including New York Founders Roundtable. At LifeX, he brings technical curiosity and operating experience to working with founders on consequential decisions.

Jon Soberg is a Partner at LifeX Ventures, Fund II. An engineer, entrepreneur, and early-stage investor, he brings more than 15 years of venture capital experience and a track record of backing founders across five continents.

Jon earned a BS in Engineering from Harvey Mudd College and a master's degree in engineering from Northwestern University. He later received his MBA in Entrepreneurial Management and Marketing from The Wharton School, where he was a Palmer Scholar, and he holds the CFA charter. He has since returned to Wharton as a lecturer and Senior Fellow.

Before investing, Jon built companies himself. He was head of engineering at Adforce, which went public, and later held senior operating and finance roles at GMAC Mortgage, Ditech, HSBC, Capital Group, and Great-West Life. That mix of engineering, consumer finance, and large-scale operations shapes how he evaluates products and the businesses around them.

Jon began his venture career as a Partner at Blumberg Capital, investing in enterprise software and fintech, and went on to lead MS&AD Ventures as CEO and Managing Partner, the Silicon Valley venture arm of one of the world's largest insurance groups. He has made more than 120 investments, taken dozens of board and observer seats, and has been ranked among Business Insider's top seed investors worldwide.

At LifeX, Jon brings a builder's perspective and deep experience in insurance, risk, and financial infrastructure — areas where health care is being redesigned. Founders value his candor and his view that people, more than ideas, determine which companies endure.

At LifeX, Lisa helps founders with the commercial questions that follow a strong product: which partners matter, how to enter new markets, and how to build distribution that lasts.

Fabian Siegel is a Partner at LifeX Ventures, Fund II. A six-time founder and operator, he has spent more than two decades building consumer internet and marketplace businesses in Germany, Europe, and the United States.

Fabian studied Economics and Law at the University of Bonn. He began his career in technology, serving as CTO of ClickandBuy, the online-payments company later acquired by Deutsche Telekom.

From 2010 to 2013 he was co-CEO of Delivery Hero (Lieferheld) alongside Niklas Östberg, helping build what became one of the world's largest food-delivery platforms, which went public in Frankfurt in 2017. He then served as a Venture Partner at Global Founders Capital.

In 2014 Fabian founded Marley Spoon, the meal-kit company behind Marley Spoon and Dinnerly, and led it as CEO for a decade, through expansion across three continents and a public listing on the Australian Securities Exchange, before stepping down in 2024. Along the way he has personally invested in more than 30 startups.

At LifeX, Fabian brings hard-won lessons in scaling logistics-heavy, consumer-facing businesses and in the operating decisions that come with them — experience that is directly relevant to founders building new models of care delivery and access.
