We cover: - The shift from systems of record to systems of action why AI-native UX lowers adoption friction - Verticalized spend management vs horizontal cards (when niches win; construction/healthcare examples) - The AI margin debate: inference costs, valuation sanity, and why true retention/cohorts matter - AR glasses and real vertical use cases once hardware reaches “consensus” (field service, supply chain, healthcare) - The ACV Auctions playbook: uniform info + guarantees, region-first scaling, and how to “hot-wire” marketplace liquidity - Operators → investors: how operator empathy changes selection, support, and outcomes If you’re building in SaaS, AI, or service-based marketplaces, this one’s for you.
