AI Drives Enterprise In-House Software

The author argues that a "**SaaS mass extinction**" won't happen, but anticipates more nuanced shifts: - **High-barrier, knowledge-dense** software will persist long-term, especially in high-stakes sectors like healthcare and taxes. - However, **custom/in-house enterprise software** development will massively accelerate in the coming years, spreading like wildfire. - Some SaaS will evolve into AI-friendly, **API-first** products; others will remain strictly internal, powered by a mix of self-trained/fine-tuned models and frontier models. - The author predicts the emergence of **millions or even billions of customized software stacks**. The post highlights a case where a team replaced Salesforce with a **vibe-coded CRM**. The custom system perfectly matched internal workflows and slashed **$600,000 in annual software fees** down to zero.
