The New Economics of AI | Martin Casado & Steven Sinofsky
Martin Casado and Steven Sinofsky discuss how AI is fundamentally shifting the computing industry from an engineering-constrained problem to a capital-constrained one, examining what recent AI breakthroughs in mathematics actually indicate about economic value creation and the changing competitive dynamics between startups and incumbents.
Why Medical AI Needs a Referee | Protege's Engy Ziedan
Engy Ziedan, co-founder of Protégé, argues that medical AI faces a critical evaluation gap: models can ace benchmark exams but fail in real clinical settings, and independent oversight is essential because hundreds of millions use AI for health advice with no one ensuring safety or correctness. Protégé is positioning itself as an impartial referee to continuously evaluate AI models in healthcare through real-world data rather than static benchmarks.
Martin Casado on Where the Value Is Going in AI
Martin Casado discusses how AI has fundamentally changed venture capital economics by enabling small teams to productively deploy massive amounts of capital directly into growth, using recent acquisitions like Cursor ($60B) and OpenRouter by Stripe as examples of value accruing across the AI stack rather than consolidating entirely at frontier labs.
How Microsoft Is Securing the Agentic Enterprise | Aaron Zollman
Aaron Zollman, Microsoft's Deputy CISO, discusses securing AI agents in enterprise environments by applying security fundamentals like containerization, identity management, and monitoring. He argues that while AI models can exploit unexpected security paths and behave unpredictably, organizations can manage these risks using established security practices rather than entirely new paradigms, and that the CISO role is shifting from risk prevention to enabling safe adoption of powerful new technologies.
How Global Networks Are Reshaping Startup Success
A16Z partners Angela Strange and Gabriel Vasquez discuss their strategy of identifying and supporting 'borderless founders'—international entrepreneurs building global companies. They explain how diaspora networks, talent pools, customer access, and brand advantages give international founders unique competitive edges, and how AI is accelerating the shift toward globally distributed startup ecosystems.
How Whatnot Built a Global Marketplace
Grant LaFontaine, co-founder of Whatnot, discusses how the platform transformed live commerce from a niche Asian trend into a major marketplace by focusing on user experience rather than market mechanics. The company has built a $16+ billion annualized GMV business empowering small sellers across 100+ categories while maintaining human-centric connections between buyers and sellers.
How Do You Defend Against AI That Can Hack?
Security teams face unprecedented challenges as AI models become sophisticated enough to autonomously hack systems, escape containment, and bypass traditional defenses. Current cybersecurity tools built to defend against humans and malware are fundamentally inadequate for AI agents, requiring a complete rethinking of defensive strategies.
Ben Horowitz and Travis Kalanick on Building Again
Travis Kalanick discusses his eight-year hiatus from the public eye while building his new company Atoms, focusing on industrial AI across food, mining, and other trillion-dollar industries. He reflects on his evolution as a founder, differences between his Uber and Atoms approaches, and explains his decision not to acquire Lyft, while Ben Horowitz shares insights on entrepreneurship and the changed media landscape.
The Two Ways to Sell AI: Lighthouse or Landgrab?
A16Z partners Joe Schmidt and Andy McCall discuss two competing enterprise AI sales strategies: Lighthouse (targeting high-profile customers to establish credibility in regulated/innovative markets) and LandGrab (pursuing numerous mid-market customers with existing budgets and proven ROI). They argue that early-stage AI founders often mistakenly prioritize prestigious logos over pursuing customers willing to buy, and share lessons from building sales organizations at Meraki and Samsara.
