Air Street Capital

Air Street Capital is a venture capital firm investing exclusively in AI-first companies — those for which advances in artificial intelligence are the primary driver of product capability, competitive advantage, and long-term value creation. Founded in 2019 by Nathan Benaich as a solo GP, the firm invests globally with a focus on Europe and the United States, backing founders building frontier AI systems, infrastructure, and applications that are technically differentiated and research-driven from day one. The firm primarily leads at pre-seed and seed stages with checks of $500k–$15M, and selectively makes growth-stage investments up to $25M. Air Street's focus spans AI-first software, developer tools and infrastructure, TechBio and AI-native life sciences, autonomous systems and robotics, and defense and national security — areas where AI is not simply improving the status quo but enabling entirely new kinds of products and companies. The firm is closely coupled to the frontier of AI research through the State of AI Report, the most widely read independent annual analysis of global AI progress, which informs its long-term investment perspective and technical judgment.
