Jeff Karras

Jeff Karras is a General Partner at America's Frontier Fund and co-founder of Alter Venture Partners, bringing over 20 years of venture capital experience to the intersection of deep tech, national security, and U.S. strategic competitiveness. With more than 40 investments and 23 exits - including 6 IPOs - he has backed companies spanning semiconductors, advanced manufacturing, synthetic biology, and AI. Before pivoting to frontier tech, he helped build SingTel Innov8's North American and Israeli operations and spent nearly a decade at Levensohn Venture Partners. A licensed pilot based in San Francisco, he is among a small cohort of investors who believe the most important technology companies of the next decade will emerge from the overlap of commercial innovation and government-scale problems.
