Summary

Generative AI is rapidly transforming the enterprise software landscape, dismantling the traditional "one-size-fits-all" model that forced companies to adapt their workflows to standardized tools. Published on April 23, 2026, this article highlights how generative AI makes it fast and feasible to build custom systems tailored to specific organizational needs. Enterprise spending on generative AI applications surged from $1.7 billion in 2023 to $37 billion in 2025, significantly impacting the global software market and leading to sharp compressions in public SaaS valuations. This shift is driven by the increased speed of AI adoption, the fact that 40% of code is now AI-generated, and early substitution effects where over a third of companies are replacing SaaS tools with custom AI alternatives. The core strategic question for leaders is now which workflows to own and customize versus which to outsource or standardize.

Key takeaway

For AI Product Managers evaluating enterprise software strategies, the rise of generative AI demands a re-evaluation of your organization's core workflows. You should strategically decide which functions truly differentiate your company and invest in building or deeply customizing those, rather than defaulting to standardized SaaS. Focus on robust data architecture and governance for any custom AI systems to ensure quality and maintainability, recognizing that these technology decisions directly impact organizational design and competitive advantage.
