Gtm Expert · chaichiang bundle Diagnose SaaS, AI, product-led, sales-led, marketing, retention, activation, positioning, launch, founder-selling, and growth problems with source-traceable guidance organized by GTM lifecycle stage. Use when a founder or operator asks what to prioritize, how to launch or sell a product, whether to launch privately or under a brand/pseudonym, how to handle fear of criticism or selling, whether PMF exists, which GTM motion fits, whom to hire, or which experiment to run. After the user enters a GTM consultation, also use for all follow-up messages in that consultation—including short replies such as “继续”, objections, new facts, revisions, and requests to test another option—until the user explicitly asks to exit or stop using the skill. Route by stage and problem, preserve source provenance and evidence limits, and produce a compressed actionable decision.
