Wednesday's deep dive into support, HR, and finance reveals synchronized AI-native disruption across all three: in finance, Basis hits $1.15B unicorn for autonomous accounting agents while Rowspace raises $50M for PE portfolio intelligence; in support, Zendesk acquires Forethought for self-improving agents and Intercom Fin hits 67% resolution rates; in HR, Alex raises $20M for AI video interviewing. The pattern: each category's AI-native challenger doesn't just add AI features to existing workflows — it architecturally eliminates the human-in-the-loop that defined the SaaS category in the first place.
