Key Insight: The Hybrid Approach Wins
Pure AI proposals underperform because they lack personalization. Pure manual proposals are too slow — by the time you send it, a faster competitor has already won. The sweet spot? AI draft + 20 minutes of human customization = highest win rate AND fastest turnaround.
