Picks the two or three marketing bets that fit a software product's stage, budget and team, and turns each into a sized test with a pass mark and a stop rule. Use when someone asks "how do I market this", "give me marketing ideas", "growth ideas for my SaaS", "which channel should we try next", "what should marketing do this quarter", or "we have a small budget, where do we start". Works from the product's own numbers: it backs the goal out into traffic and cost limits, screens channel families against what must be true for each, and writes the plan as a short document instead of a long list of tactics.
