Base44’s Founder, Maor Shlomo on How Vibe Coding Will Kill SaaS

From 20VC with Harry Stebbings

Maor Shlomo•Founder, Base44

Executive Summary

Base 44 founder Mayol discusses his company's $80M acquisition by Wix and its subsequent growth to over $100M in revenue, attributing success to the strategic partnership.
Mayol predicts a paradigm shift in software, where AI-native tools ("vibe coding") will make it easier for businesses to build custom applications (like CRMs) than to buy and implement off-the-shelf SaaS products like Salesforce.
The primary competitive moat for AI application companies is not the AI model itself, but a vertically integrated platform infrastructure, as models are becoming commoditized with low switching costs.
For AI application companies, model costs represent 90-99% of spend, creating a strategic imperative to either build proprietary, efficient models or find other ways to defend margins and build a defensible business.

10 quotes

Concerns Raised

The lack of durable moats for AI application companies that are merely thin wrappers over third-party models.
The potential for dominant LLM providers to move up the stack and compete directly with application-layer companies.
The high cost of models (90-99% of spend) creates significant margin pressure for AI application businesses.
The traditional 'winner-take-all' VC thesis may not apply to the AI-native software market.

Opportunities Identified

Disrupting the traditional SaaS market by enabling users to build their own custom solutions with AI.
Building a strong competitive moat through vertically integrated platform infrastructure.
The massive, untapped market for AI-assisted coding tools, with adoption expected to reach near 100% in tech companies.
The commoditization of LLMs allows for rapid innovation at the application layer for companies with a clear strategy.

Key Themes

The Future of Software Development: Vibe Coding

The episode's central thesis is that AI will fundamentally change how software is created. Mayol predicts that "vibe coding"—prompting AI agents to build applications—will become so efficient that building custom software will be preferable to buying generic SaaS solutions, leading to hyper-customized, liquid software.

This signals a potential mass disruption of the traditional SaaS market, where incumbents like Salesforce, which rely on a 'one-size-fits-all' model and costly implementers, could become obsolete.

Building Defensible Moats in the AI Era

The discussion highlights the difficulty of building a sustainable business on top of third-party LLMs, which have low switching costs. Mayol argues that the true moat lies in building a vertically integrated platform with its own backend infrastructure, as Base 44 did, rather than being a thin wrapper like Jasper AI.

This provides a critical framework for founders and investors evaluating AI startups. A company's defensibility is tied to its unique infrastructure and data, not just its use of a popular AI model.

The Economics and Strategy of AI Applications

AI model costs can account for 90-99% of an application company's expenses, posing a significant challenge to profitability. A viable strategy, exemplified by Cursor, is to first achieve massive distribution using third-party models and then introduce a proprietary, more efficient model to capture margin.

This insight is crucial for understanding the business models of AI-native companies. Long-term success depends on a clear strategy to manage model costs and avoid being squeezed by foundation model providers.

Founder Strategy: Acquisition vs. Venture Capital

Mayol details his decision to sell Base 44 to Wix for $80 million instead of raising a large venture round. He chose acquisition to leverage Wix's massive distribution, marketing, and operational support, believing it gave him a higher probability of building a truly impactful, large-scale company.

This offers a counter-narrative to the typical VC-funded path, illustrating how a strategic acquisition can be a powerful accelerator for a founder's ultimate vision, especially in a capital-intensive and highly competitive market.
