AI’s Impact on SaaS Will Be Uneven. Here’s What Leaders Need to Know.

Harvard Business Review· June 14, 2026

The software-as-a-service (SaaS) industry is facing a significant transition as artificial intelligence begins to disrupt the traditional model of workflow digitization. For two decades, SaaS providers have generated value by organizing disorganized data into accessible tools for workers, such as CRM and field-service platforms. However, the emergence of AI coding tools is now lowering the barrier for companies to build custom software in-house, threatening the historical competitive advantages of established vendors.

For approximately twenty years, the software-as-a-service (SaaS) sector has achieved growth primarily by digitizing manual workflows and centralizing business data. According to the report, this evolution was characterized by the rise of customer relationship management (CRM) systems that recorded sales activities and field-service platforms designed to schedule jobs and retrieve customer histories. By taking opaque or messy information and placing it directly into the hands of workers, these platforms created significant operational value and became essential components of the modern enterprise tech stack.

A key driver of the SaaS model's success was the technical barrier to entry for individual buyers. Before the advent of advanced AI coding tools, very few companies were positioned to build comparable feature sets internally, effectively creating a moat for software vendors. These platforms did more than just store data; they actively supported revenue generation by feeding upsell opportunities back into sales teams and streamlining field operations, making the cost of third-party subscriptions a justifiable investment for most businesses.

The landscape is now shifting as AI-driven development tools empower organizations to potentially create their own software solutions. This technological shift directly challenges the traditional SaaS value proposition, as the difficulty of building complex workflow tools—once a primary reason for purchasing software—is diminishing. As a result, the impact of AI on the SaaS market is expected to be uneven, forcing industry leaders to reconsider how they provide value in an environment where custom, in-house feature sets are becoming increasingly attainable for their customers.
