Three wedge patterns stand out this week. First, the bowling center story is a template: legacy vertical SaaS in physical industries (bowling, hospitality, fitness) charges monopoly prices and is wide open to hardware-plus-software disruption at a fraction of the cost. Second, AI agent security and session management is crystallizing into its own tooling layer, with credential gateways, context warmers, and agent registries all appearing independently, signaling that founders who build the "safety and observability plumbing" for agents will find sticky B2B demand. Third, the cluster of open-source alternatives to Adobe, Microsoft, and GitHub products (Imagin Raw, Bento, Word in Web, Twigg) confirms that local-first and self-hostable replacements for bloated creative suites remain a reliable wedge, especially when paired with a sharp price or privacy angle.
