Artist's co-founder warns that the biggest mistake founders make is building technology too early. Her team validated their text-based learning concept by manually texting early users, confirming the core hypothesis and user engagement before committing significant engineering resources.

Many teams wrongly focus on the latest models and frameworks. True improvement comes from classic product development: talking to users, preparing better data, optimizing workflows, and writing better prompts.

After testing a prototype, don't just manually synthesize feedback. Feed recorded user interview transcripts back into the original ChatGPT project. Ask it to summarize problems, validate solutions, and identify gaps. This transforms the AI from a generic tool into an educated partner with deep project context for the next iteration.

For AI products, the quality of the model's response is paramount. Before building a full feature (MVP), first validate that you can achieve a 'Minimum Viable Output' (MVO). If the core AI output isn't reliable and desirable, don't waste time productizing the feature around it.

To test complex AI prompts for tasks like customer persona generation without exposing sensitive company data, first ask the AI to create realistic, synthetic data (e.g., fake sales call notes). This allows you to safely develop and refine prompts before applying them to real, proprietary information, overcoming data privacy hurdles in experimentation.

Non-technical founders using AI tools must unlearn traditional project planning. The key is rapid iteration: building a first version you know you will discard. This mindset leverages the AI's speed, making it emotionally easier to pivot and refine ideas without the sunk cost fallacy of wasting developer time.

Historically, resource-intensive prototyping (requiring designers and tools like Figma) was reserved for major features. AI tools reduce prototype creation time to minutes, allowing PMs to de-risk even minor features with user testing and solution discovery, improving the entire product's success rate.

Instead of seeking a "magical system" for AI quality, the most effective starting point is a manual process called error analysis. This involves spending a few hours reading through ~100 random user interactions, taking simple notes on failures, and then categorizing those notes to identify the most common problems.

A powerful but unintuitive AI development pattern is to give a model a vague goal and let it attempt a full implementation. This "throwaway" draft, with its mistakes and unexpected choices, provides crucial insights for writing a much more accurate plan for the final version.
