a16z Podcast Dec 03, 2025 english 5 min read

AI is shifting software's market from IT to labor, creating both intense competition and vast new opportunities for businesses that strategically leverage its power.

Key Insights

  • Insight

    AI fundamentally shifts the market opportunity for software from traditional IT spend to direct labor spend, as software can now perform complex tasks.

    Impact

    This expands the total addressable market for software into new sectors previously reliant on human labor, creating massive economic shifts and potential for new company formation.

  • Insight

    Business 'moats' (defensibility) still matter and are largely consistent with pre-AI eras (e.g., owning workflow, system of record), while AI itself primarily serves as a tool for differentiation.

    Impact

    Companies must focus on deep customer embedding and network effects for long-term defensibility, recognizing that AI capabilities alone will not guarantee a sustainable competitive advantage.

  • Insight

    The economic value of a "feature" has transformed; what was once a minor addition can now command significant revenue by replacing an entire person's job.

    Impact

    This creates new avenues for startups to monetize highly specialized solutions and enables businesses to achieve unprecedented efficiency gains by automating specific human roles.

  • Insight

    AI simultaneously fosters "infinite competition" due to lowered barriers to software creation, and "trillion dollar opportunities" in previously untouched or unviable markets.

    Impact

    Entrepreneurs face intense competition but also have unprecedented access to new, profitable market segments by leveraging AI to make previously uneconomical services viable.

  • Insight

    Incumbent AI model providers will likely focus on being foundational platforms and developing big horizontal enterprise applications, leaving obscure vertical markets for others.

    Impact

    Startups should target these niche "Goldilocks zone" vertical markets, recognizing that direct competition from large AI platform owners is less likely in highly specialized areas.

  • Insight

    AI's primary impact is not job destruction, but enabling the creation of new services and tasks that were previously too expensive, complex, or impractical for human labor.

    Impact

    This leads to a "Cambrian explosion" of new business models and customer value propositions, fostering economic growth and new forms of human-AI collaboration.

  • Insight

    Reaching 'gravitational scale' is crucial for establishing moats and surviving consolidation in competitive AI markets, making momentum critical in the early stages.

    Impact

    Companies must aggressively pursue growth and market dominance in their chosen niches to withstand intense competition and achieve the scale necessary for defensibility.

Key Quotes

"The thing that is fundamentally different about this product cycle is that the software itself can actually do the work. And therefore, the market opportunity for software today is no longer just IT spend, it's largely labor."
"The counterintuitive reality is this. The same force creating infinite competition is also creating trillion dollar opportunities in places nobody's looking."
"I've never been able to hire somebody for a dollar. Now I can hire software for a dollar."

Summary

AI's Dual Impact: Navigating the New Landscape of Software and Labor

The advent of artificial intelligence is fundamentally reshaping the economic landscape, signaling a shift in how value is created and captured across industries. Far from being just another technological upgrade, AI empowers software to "do the work" previously performed by humans, transforming market opportunities from traditional IT spend into vast labor savings and new service creation. For leaders, investors, and entrepreneurs, understanding this profound reorientation is critical for future success.

The Great Market Re-evaluation: From IT Spend to Labor Spend

Historically, software targeted IT budgets, optimizing existing processes. Today, AI's capability to automate complex tasks means the market opportunity for software now primarily addresses labor spend. This expansion opens up entirely new sectors, such as plaintiff law and auto loan servicing, that were previously deemed too niche or human-intensive for software intervention. Companies are now charging significant sums for "features" that directly replace an entire person's role, demonstrating the immense value being unlocked.

Moats Evolve: Differentiation vs. Defensibility in the AI Era

While AI offers unprecedented tools for differentiation – imagine a voice agent speaking 50 languages compliantly, 24/7 – this "AI-ness" itself is not a source of defensibility. Instead, sustainable moats still reside in core business principles: owning the end-to-end workflow, becoming the system of record, leveraging network effects, and deeply embedding within customer operations. The ease of creating AI-powered software fosters infinite competition, yet paradoxically, it simultaneously creates trillion-dollar opportunities by enabling entry into previously untouched markets.

The "Goldilocks Zone" and Greenfield Strategies

Successful navigation requires identifying the "Goldilocks zone" – markets where a product is crucial enough to be indispensable, but not so critical that it attracts immediate, overwhelming competition from giants. Payroll services, for instance, exemplify this: essential but low-priority for switching, creating strong customer stickiness. Greenfield markets, where new companies are formed and lack entrenched solutions, represent significant growth potential. However, these demand patience and a high rate of new company creation, as building scale from zero against numerous "ankle-biters" remains challenging.

Incumbents and the Future of Work

Large AI model providers like OpenAI and Google are strategically focused on two fronts: establishing themselves as foundational backends for all developers and building horizontal enterprise applications (e.g., advanced IDEs). They will likely leave highly verticalized, obscure applications to startups, taxing usage on their platforms. Critically, AI's impact on employment is less about widespread job destruction and more about enabling new services. By dramatically reducing the cost of tasks, AI facilitates the creation of entirely new categories of services that were previously uneconomical or impractical to offer with human labor, leading to a "Cambrian explosion" of possibilities.

Conclusion

The AI era is defined by profound transformation, where traditional market boundaries dissolve and new opportunities emerge from the confluence of advanced software capabilities and labor-cost reduction. Success hinges on a clear understanding of evolving defensibility strategies, a keen eye for untapped "Goldilocks" and greenfield markets, and the strategic embrace of AI to create unprecedented value, not merely to automate existing roles.

Action Items

Re-evaluate existing business processes and market opportunities through the lens of "labor spend" replacement, identifying tasks that AI can automate to create new value.

Impact: This strategic shift can unlock significant cost savings, expand service offerings, and open up entirely new revenue streams by optimizing human-centric workflows.

Prioritize deep integration into customer workflows and becoming a system of record to build sustainable moats, rather than solely relying on advanced AI capabilities for differentiation.

Impact: This approach ensures long-term defensibility and customer stickiness, making it harder for competitors to displace the product even if they offer similar AI features.

Target "Goldilocks zone" markets – specialized areas where AI-powered features can deliver high value by replacing labor, yet are too niche to attract immediate competition from major platforms.

Impact: This strategy allows startups to build defensible positions and significant revenue quickly, by focusing on underserved segments with high willingness to pay for labor automation.

Cultivate entrepreneurial patience and seek markets with a high rate of new company creation for greenfield opportunities, understanding that scale takes time to build.

Impact: This allows businesses to establish long-term market leadership in emerging sectors, despite potentially slower initial traction compared to more established markets.

Develop strategies to orchestrate across multiple foundational AI models rather than locking into a single provider, reducing platform risk and ensuring flexibility.

Impact: This mitigates dependency on any one large AI company, allowing for adaptation to evolving model capabilities and pricing structures, maintaining competitive agility.

Focus on creating entirely new services or expanding existing ones that were previously unviable due to human labor costs, leveraging AI to achieve unprecedented abundance and affordability.

Impact: This strategy transcends mere automation, opening vast new markets and improving customer experiences by providing personalized, low-cost services at scale.
