The primary threat AI agents pose to platforms like DoorDash or Uber isn't that they can "vibe-code" a replacement app. It's that they can eliminate the friction of price shopping, thereby commoditizing the demand side of the marketplace and destroying the customer lock-in that constitutes the company's core value.

In the near future, AI agents will automatically reorder everyday products based on a user's established brand loyalty. This makes brand affinity more valuable than ever, as competitors will need to create extreme relevance to compel a user to manually override their AI's purchasing habits.

Companies like Uber and DoorDash build moats on customer lock-in. AI agents will eliminate this by automatically price-shopping for users, commoditizing demand. This shifts the competitive battleground to supply-side aggregation, lowering barriers to entry for new players.

AI agents shop based on optimized specs, not human heuristics like brand trust. This shift to "agentic commerce" could neutralize the power of major brands like Walmart and Amazon, and eliminate the interpersonal relationships that sustain local, small businesses.

To survive the threat of AI commoditizing services, businesses must build a strong brand. The goal is for customers to ask for your company by name (e.g., "Alexa, send me a Pizza Hut") rather than a generic request ("send me a pizza"), making you a destination, not an option.

The "DoorDash Problem" posits that AI agents could reduce service platforms like Uber and Airbnb to mere commodity providers. By abstracting away the user interface, agents eliminate crucial revenue streams like ads, loyalty programs, and upsells. This shifts the customer relationship to the AI, eroding the core business model of the App Store economy's biggest winners.

Service company CEOs believe strong brand loyalty is their primary defense against the "DoorDash Problem." Lyft's CEO argues that users are more likely to ask an AI specifically for "a Lyft" rather than a generic "ride." They are investing in brand to ensure they are requested by name, preventing them from being disintermediated and reduced to the cheapest commodity option.

Future marketing must adapt to a world where the "customer" is an AI agent. These agents will bypass traditional persuasive tactics and brand narratives, instead performing objective, data-driven comparisons to find the best product. This forces brands to compete purely on measurable value and utility, fundamentally changing marketing strategies.

Similar to how mobile gave rise to the App Store, AI platforms like OpenAI and Perplexity will create their own ecosystems for discovering and using services. The next wave of winning startups will be those built to distribute through these new agent-based channels, while incumbents may be slow to adapt.
