1. The GPT Wrapper Dilemma
TL;DR > To validate an AI startup, you must prove that your value comes from proprietary workflows or data, not just the underlying LLM.
Building an AI startup is incredibly easy today. Validating a defensible AI startup is incredibly hard. If your entire product is just a UI layer over ChatGPT (a "wrapper"), your moat is zero. OpenAI will eventually release a feature that kills your company.

The API Threat
Industry analysts estimate that 90% of simple "AI Wrapper" startups built in 2023 lost their core value proposition due to native updates by OpenAI and Anthropic in 2024.
2. Validating the Workflow, Not the Output
Instead of validating the AI's output, validate the workflow integration.
If you are building an AI legal contract reviewer, don't just ask lawyers if they want "AI." Ask them if they will pay for a tool that integrates directly into Microsoft Word, automatically cross-references their specific firm's past cases, and drafts emails to clients.

3. The "Wizard of Oz" AI Test
The best way to test an AI startup is to fake the AI. Build a frontend where the user submits a prompt, but instead of an API call, it sends an email to you. You manually write the response and send it back. If they aren't blown away by a human expert's response, they won't pay for the AI's response.
