Key Quotes
"We're taking into consideration that the prices of model will go down towards zero."
"If a one person team can get sold for 80 million dollars without people, it means that you'll be able to do a lot more stuff with very little like less people."
"I think the mode in the category is being able to get there, and that's like layers of integrations and heavy lifting and building a compute, you're almost building like a small cloud because you want to give the LLM the ability to have access to databases and have user management and to have built-in integrations and the ability to run scheduled tasks because that's what real software does."
Summary
The "Vibe Coding" Revolution: Reshaping Software, Investing, and the Future of AI
The landscape of software development is undergoing a seismic shift, driven by the rapid advancements in AI, particularly Large Language Models (LLMs). This evolution, dubbed "vibe coding," promises to democratize software creation, challenge established SaaS paradigms, and redefine investment strategies. The journey of Base44, an AI app builder acquired by Wix for $80 million after just 18 months, serves as a powerful case study for understanding this dynamic new era.
The Rise of Bespoke Software and SaaS Disruption
At the core of the "vibe coding" revolution is the ability for non-technical users to build highly customized, functional applications through simple prompts. This marks a significant departure from the "one-size-fits-all" model prevalent in traditional SaaS.
The Future of Software: Liquid and Customized
Imagine a world where creating your own Salesforce-like CRM is easier than buying an off-the-shelf license. While not an immediate reality, the trajectory of AI suggests software will become increasingly "liquid." Users will start with templates or open-source projects, then "vibe code" custom features. This means software will adapt precisely to individual needs, eliminating feature bloat and vendor lock-in, especially benefiting small businesses seeking leaner, more tailored solutions.
LLM Market Dynamics: Volatility and the Pursuit of Moats
The market for LLM providers is characterized by extreme volatility and ease of switching. Unlike traditional cloud infrastructure, where migration is complex and costly, AI app builders can shift millions in LLM spending overnight based on performance, cost, and specific task suitability. This intense competition among model providers drives innovation and cost reduction, with a strategic expectation that LLM prices "will go down towards zero."
However, the true moat in AI app building isn't just about using LLMs; it's about vertical integration. Platforms that build proprietary backend infrastructure – databases, user management, authentication, integrations, and scheduled tasks – create a defensible ecosystem. This "mini-cloud" approach is substantially harder to replicate than simply creating a front-end prompting tool.
The Economics of AI Applications: Margins and Growth
Current margins for AI app builders can be high-spend due to reliance on powerful, often expensive, frontier models. Yet, this is poised to change. Strategic model routing—directing simple requests to cheaper, faster open-source or smaller models, and complex tasks to frontier models—is key to drastically improving margins and user experience.
The AI software market is vast and, importantly, not "winner-take-all." This allows multiple players to thrive by carving out niches, whether serving developers (like Cursor) or non-technical users (like Base44). The focus for many AI startups is rapid growth and distribution, with a potential future strategy of developing in-house, more efficient models to optimize margins once market share is established.
Investment Strategies for the AI Era
For investors, the AI era demands a re-evaluation of traditional metrics. While rapid revenue growth remains exciting, a critical lens must be applied to the long-term viability and moat of AI companies. Investors should prioritize businesses that are: * Vertically Integrated: Building their own infrastructure beyond just LLM orchestration. * Solving Real Problems: Often starting by addressing the founder's or a personal need. * Self-Sustainable: Demonstrating a path to healthy margins and operational efficiency.
The ability of a one-person team to build and sell a profitable business for $80 million without a large headcount underscores the immense economic value creation potential of AI. This efficiency trickles down, fostering more startups, making existing enterprises leaner, and ultimately benefiting the consumer with better, cheaper products.
Conclusion: A New Era of Building
The "vibe coding" revolution represents a fundamental shift in how software is conceived, built, and consumed. For entrepreneurs, it means unprecedented opportunities to create lean, impactful businesses. For investors, it necessitates a discerning eye for true innovation, vertical integration, and sustainable business models beyond the initial hype. The message is clear: the future of software is customized, efficient, and built by AI, for everyone.
