CONTEXT GRAPHS COULD BECOME AI'S NEXT TRILLION-DOLLAR PLATFORM

AI agents expose a missing enterprise layer: decision traces that capture exceptions, approvals, and precedent that never make it into systems of record. Startups that sit in the agent execution path can persist these traces at decision time, forming context graphs that explain not just what happened, but why it was allowed. This shifts power away from CRMs and data warehouses toward new systems of record built around decision lineage and autonomy.

Then, Volvo made lidar optional instead of standard, cutting volumes by 90%. There's a lot to unpack here about concentration risk, why "lifetime volume" projections aren't the same as purchase orders, and what happens when your only customer changes their mind.

THE REAL ECONOMICS OF SAAS VERSUS AI COMPANIES

AI companies need higher revenue or pricing power to match SaaS profit per customer due to structurally lower margins.
