Hyper-Targeted GTM Strategy Playbook

Act as a veteran Chief Marketing Officer and Go-To-Market strategist. I need a comprehensive, highly tactical Go-To-Market (GTM) playbook for my startup. Develop a custom strategy covering three distinct phases: Phase 1: Pre-launch and Positioning, Phase 2: Launch and Initial Traction (First 100 Customers), and Phase 3: Post-launch Scale. For each phase, specify: 1. Key Channels (organic and paid), 2. Actionable tactics with step-by-step execution details, 3. Success Metrics (KPIs) to track, and 4. Estimated resource requirements. Here are the details of my startup: Product Category and Type: [insert product category, e.g., B2B productivity app], Ideal Customer Profile (ICP): [insert ICP, e.g., Remote marketing agency owners with 10-50 employees], Pricing Model: [insert pricing model, e.g., 49 USD per user per month], Total Marketing Budget: [insert budget, e.g., 5000 USD total for launch phase]. Do not suggest generic advice; provide creative, guerilla growth hacks alongside standard digital marketing practices.
