AI Agent: From Horizontal to Vertical Growth #shorts

In this short monologue, Jason Lemkin explains the development and evolution of a "digital Jason" AI agent. Initially designed as a horizontal, general‑purpose assistant that could handle a little bit of everything, the agent was unexpectedly used for support tasks, event logistics, and sponsor requests. This unanticipated usage led to hallucinations until the team uploaded their prospectus, providing enough context to improve accuracy. Lemkin notes that the agent achieved roughly 20% of the functionality of the specialized tool Qualified, yet this partial capability still delivered meaningful ROI by answering most customer questions instantly, outperforming their previous Intercom setup. He argues that delivering a modest horizontal solution first builds confidence, after which the product can be expanded into multiple verticalized agents (e.g., SDR, BDR, marketing). The overall message is that a modest horizontal AI can be valuable and serves as a stepping stone toward a suite of specialized agents.
