The SaaS empire strikes back

The article outlines four strategic paths for legacy SaaS companies to navigate the AI disruption: maintaining Rule of 40 profitability while partnering with AI-native startups, pursuing Rule of 60 profitability for PE-style cash optimization, going on an AI offensive to compete directly, or pivoting the entire business toward AI products. The author argues that most mature SaaS companies should pursue the AI offensive (Path 3) while accepting meaningful trade-offs, and warns against attempting to hedge across all options simultaneously.
