Kevin Novak trained as a nuclear physicist before becoming Uber's 21st employee, where he invented its dynamic pricing system and spent nearly seven years building its data products, later drawing on that logistics experience to back Nash and help hire its early team. At Rackhouse Venture Capital, he focuses on AI companies solving real problems rather than chasing hype, helps founders directly with hiring, sourcing, and closing customers, and also helped found the Greylock Data Science Community while advising universities on their data science programs.
