To identify when a technology is truly being disrupted, look for its "fax machine moment." In 1999, after years of slowing growth, physical fax machine sales abruptly dropped 10% in a single year, signaling the definitive start of the decline. This is the key signal to watch for in legacy SaaS revenues.

The "SaaSpocalypse" is not an indiscriminate event. A clear divergence is emerging between SaaS companies that are successfully integrating AI to strengthen their business models and those legacy companies that are unable to pivot, becoming "sloppable."
The "SaaS-pocalypse" isn't about AI replacing software overnight. Instead, AI's disruptive potential erases the decades-long growth certainty that justified high SaaS valuations. Investors are punishing this newfound unpredictability of future cash flows, regardless of current performance.
Unlike mobile or cloud, which were sustaining innovations that enhanced existing SaaS models, AI is a disruptive force. It fundamentally challenges seat-based pricing and requires a difficult, full-stack pivot of a company's business model, culture, and organizational structure.
To gauge AI's true impact on SaaS giants, ignore their slow-to-change enterprise customers. Instead, analyze the adoption patterns of new, small companies. If startups are skipping established SaaS platforms for AI tools, it signals a bottom-up disruption that will eventually reach the enterprise.
The ongoing decline in growth rates for public SaaS companies has created an existential crisis around revenue durability. Investors have lost confidence that traditional SaaS models can sustain growth in the face of AI disruption, leading to a massive valuation collapse.
In the age of AI, 10-15 year old SaaS companies face an existential crisis. To stay relevant, they must be willing to make radical changes to culture and product, even if it threatens existing revenue. The alternative is becoming a legacy player as nimbler startups capture the market.
The lucrative maintenance and migration revenue streams for enterprise SaaS, which constitute up to 90% of software dollars, are under threat. AI agents and new systems are poised to aggressively shrink this market, severely impacting public SaaS companies' incremental revenue.
Sierra CEO Bret Taylor argues that transitioning from per-seat software licensing to value-based AI agents is a business model disruption, not just a technological one. Public companies struggle to navigate this shift as it creates a 'trough of despair' in quarterly earnings, threatening their core revenue before the new model matures.
The push for AI-driven efficiency means many companies are past 'peak employee.' This creates a scenario analogous to a country with a declining population, where the total number of available seats is in permanent decline, making per-seat pricing a fundamentally flawed long-term business model.
