The resilience of SaaS tool companies like Twilio stems from their deep, decades-long relationships with complex networks (e.g., mobile carriers). This "agentic infrastructure" is something AI agents will use off-the-shelf rather than attempt to replicate, creating a durable moat that isn't vulnerable to being "vibe coded" away.
When asked if AI commoditizes software, Bravo argues that durable moats aren't just code, which can be replicated. They are the deep understanding of customer processes and the ability to service them. This involves re-engineering organizations, not just deploying a product.
As AI and better tools commoditize software creation, traditional technology moats are shrinking. The new defensible advantages are forms of liquidity: aggregated data, marketplace activity, or social interactions. These network effects are harder for competitors to replicate than code or features.
As AI makes the software itself easier to build and replicate, the durable value of a SaaS company is no longer the code. Instead, the moat lies in the customer relationship, the proprietary data, the system of record it represents, and the deep understanding of user workflows.
CEOs of platforms like ZocDoc and TaskRabbit are not worried about AI agent disruption. They believe the immense complexity of managing their real-world networks—like integrating with chaotic healthcare systems or vetting thousands of workers—is a defensible moat that pure software agents cannot easily replicate, giving them leverage over AI companies.
The term "unsloppable" describes companies whose competitive advantage isn't their codebase, which AI can replicate. Instead, their strength comes from durable moats like hardware, strong network effects (Uber), exclusive IP (Disney), or physical infrastructure, which are difficult for AI-powered startups to clone.
As AI makes software development nearly free, traditional engineering moats are disappearing. Businesses must now rely on durable advantages like network effects, economies of scale, brand trust, and defensible IP to survive, becoming "unsloppable."
As AI accelerates technological progress and shortens relevance cycles, traditional tech moats become less defensible. However, network effects—especially in complex, fragmented marketplaces—remain a powerful and durable advantage. An AI agent cannot be simply prompted to "create a network effect."
The threat of AI models replicating SaaS features is real. Superhuman's defense isn't a superior core technology but a platform strategy. The bet is that users won't build their own tools if the platform offers a powerful network effect of pre-built, integrated agents that work everywhere, creating a defensible ecosystem.
As AI makes it possible to replicate any SaaS application's features within days, the defensibility of a product no longer lies in its engineering complexity. The real, enduring moat is the network effect, which AI cannot trivially reproduce.
The threat of AI to SaaS is overstated for companies that own either a deep relationship with the user or a critical system of record. "Glue layer" SaaS companies without these moats are most at risk, while those like Salesforce (owning the customer relationship) are more durable.
