I Failed 47 Times Before Finding Product-Market Fit Last year, I burned through $50K testing different marketing approaches. Today, those lessons helped us close $2.7M in enterprise deals. Here's the framework that changed everything: The 72-Hour Test Method 1. Start Small, Start Smart - Pick ONE channel - Test for exactly 72 hours - Maximum budget: $500 - Measure only 2 metrics 2. The Kill Switch Protocol If after 72 hours you don't see: - At least 3 qualified leads - Or 1 serious sales conversation Kill it. Move on. No emotions. 3. Scale What Works When you find a winner: - Double budget weekly - Keep metrics stable - Document everything - Build systems first Real Example: We tested LinkedIn outreach for enterprise sales. First 72 hours: 2 qualified leads Second test: 5 leads Third test: 12 leads Killed 46 other experiments that failed this framework. The Math: - 47 total experiments - 72 hours each - 1 massive winner - $2.7M in revenue Key Learning: Most founders test too long and scale too slow. Your market will tell you what works in 72 hours. The Framework: 1. Define success metrics upfront 2. Set a hard stop at 72 hours 3. Be ruthless about killing experiments 4. Double down fast on winners What experiment are you running right now that should've been killed 72 hours ago? Want to see the exact templates and metrics we used? Connect with me.
