  1. Decagon Crosses $100M ARR Betting Against Forward-Deployed EngineersDecagon, a three-year-old AI customer-service agent startup valued at $4.5 billion, crossed $100 million in annualized revenue while deliberately avoiding the forward-deployed engineer model rivals like Sierra use to customize deployments.
  2. Sierra Raises $350M at $10B -- Bret Taylor's Agent Company Triples in a YearSierra, the customer-service AI agent company from ex-Salesforce co-CEO Bret Taylor, raised $350M at a $10B valuation -- roughly 3x its mark from a year ago. Enterprises are paying for agents that actually resolve tickets, and Sierra is the clearest commercial proof that vertical agents, not chatbots, are where the money is.
  3. Salesforce Buys Fin (formerly Intercom) for $3.6B to Supercharge AgentforceSalesforce agreed to acquire Fin -- the AI customer-service agent business formerly known as Intercom -- for $3.6B, folding it into its Agentforce platform. It's a direct bid to own the AI customer-service category before vertical agent startups like Sierra run away with it.
