Zest推出AI代理：短信订餐+口味投票全闭环

Zest launches AI agent that finds restaurants and books reservations via SMS

TechCrunch AI confirms Zest has launched an AI agent that 'can combine everyone's tastes, put restaurant options to a vote, and make the reservation' — fully operational over SMS. This is among the rare, media-verified examples of a production AI agent completing a real-world transactional loop (not just a demo or API test). Contrast this with ('Basically no one is using AI agents for their DoorDash orders') and (DoorDash reports only 'several hundred' AI-generated orders), and Zest's success highlights three critical factors for vertical agents: low-friction access (no app install), bounded task scope (meal booking), and trusted action execution (live reservation). For founders, this validates the 'narrow-scenario, deep-closed-loop' strategy over generic agent ambitions. Prioritize domains with strong payment or fulfillment infrastructure — and where users will pay per task (e.g., $2.99 per booking) — rather than chasing broad 'agentic intelligence' without monetizable outcomes.
