Last month, I watched a startup demo their "customer support agent" that handled 47 complex queries without touching Zendesk once. The founder casually mentioned they'd cancelled three SaaS subscriptions that week. I realized we're not just watching another tech trend—we're seeing the second great unbundling of software.
The numbers tell a stark story. Enterprise AI has exploded from $1.7B in 2023 to $37B currently, capturing 6% of the global SaaS market. That's not gradual adoption—that's a landgrab.

The mechanics are brutally simple. Companies are using frameworks like LangChain, CrewAI, and AutoGen to build custom agents that replace entire SaaS workflows. No more logging into Zendesk. No more upgrading Monday.com plans. Just autonomous execution that solves problems in real-time.
The Resistance Crumbles Fast
SaaS companies are scrambling to respond, but their moves reveal the depth of the threat:
- HubSpot launched Breeze, an agentic AI suite targeting small business operations
- ServiceNow acquired Moveworks to expand their agent capabilities across HR, IT, and finance
- Intercom and Salesforce are pivoting from charging for "access" to charging for "work done"
The desperation is palpable. When market leaders start acquiring AI assistant companies and restructuring their entire pricing models, you know the disruption is real.
Not All SaaS Dies Equally
Here's where most analysis gets it wrong. This isn't about all SaaS getting "eaten." It's about understanding which parts are vulnerable:
Easy Targets:
- Tiered pricing models (why pay for premium when agents handle the complexity?)
- Repetitive workflow tools
- Simple data manipulation platforms
Fortress Companies:
- Network-effect tools like Slack (hard to replicate community)
- High-volume data systems requiring specialized expertise
- Platforms with deep API integrations and switching costs
Bain's research confirms this split. They identify automation potential through six indicators: task repetition, error risk, data structure. High scores signal agent replacement opportunities. Low scores mean survival.
The 2027 Watershed Moment
McKinsey's projection that 30% of traditional SaaS workflows will be replaced by 2027 isn't just a forecast—it's a countdown timer. Gartner adds fuel with their prediction that 75% of customer service interactions will be AI-handled by 2026, up from 25% in 2023.
The math is unforgiving. If agents can slash 80% of licenses through API data ingestion (as some companies are already experiencing), entire SaaS categories face existential questions.
But here's the twist: this creates two types of markets. Bain calls them "gold mines" and "battlegrounds." Low-penetration areas become gold mines where AI expands the total market. High-penetration areas become battlegrounds where incumbents fight AI-native startups.
The Developer Angle
For developers, this shift demands new skills. Managing agent applications requires SRE/DevOps expertise that many teams lack. Companies are creating dedicated agent management teams—a new job category that didn't exist two years ago.
The frameworks are mature enough. The economics are compelling. The only question is execution speed.
My Bet: By end of 2025, we'll see the first major SaaS company shut down due to agent replacement. Mid-tier workflow tools with weak network effects will be the first casualties. The survivors will be those who become agent platforms rather than fighting the trend.
