While enterprises might leverage AI to build custom in-house solutions, SMBs are highly resistant to the pain of switching core systems like point-of-sale. This inertia makes niche SaaS for SMBs more defensible against the immediate threat of AI-driven replacement.

While AI can easily replicate simple SaaS features (e.g., a server alert), it poses little threat to deeply embedded enterprise systems. The complexity, integrations, and "dark matter" of these platforms create a "hostage" dynamic where ripping them out is impractical, regardless of cloning capabilities.

While foundational AI models threaten broad applications like writing aids, startups can thrive by focusing on vertical-specific needs. Building for niche workflows, compliance, and deep integrations creates a moat that large, generalist AI companies are unlikely to cross.

Contrary to the belief that AI will kill most apps, lower development costs will make it profitable to build and maintain software for smaller, niche audiences. This affordability will likely lead to an explosion of specialized apps rather than market consolidation.

Software's main competitive advantage isn't code, but its deep integration into customer data and workflows, creating high switching costs. AI threatens this moat by automating those integrated tasks, reducing customer stickiness and pricing power.

AI doesn't kill all software; it bifurcates the market. Companies with strong moats like distribution, proprietary data, and enterprise lock-in will thrive by integrating AI. However, companies whose only advantage was their software code will be wiped out as AI makes the code itself a commodity. The moat is no longer the software.

With AI commoditizing code creation, the sustainable value for software companies shifts. Customers pay for reliability, support, compliance, and security patches—the 'never ending maintenance commitment'—which becomes the key differentiator when anyone can build an initial app quickly.

Not all software is equally threatened by AI. Companies whose products are integral to creating proprietary, transactional data (like court case filings) have a strong defense. Their value is in the data and compliance layers, unlike UI-focused tools which are more easily replicated by AI agents.

The fear that AI agents will kill SaaS is overblown. Corporations will not replace mission-critical, supported software with AI-generated code from junior employees. The need for vendor accountability, reliability, and support creates a durable moat for enterprise software companies.
