Builder Lesson

Full Reasoning
Builders can learn from MarkUp's focus on a highly specific workflow: visually briefing AI on web changes. Packaging this utility as a simple Chrome extension, combined with a strong incentive like lifetime access for feedback, drives rapid user acquisition and iteration. This niche specialization and distribution method makes it difficult for broader tools to replicate its focused utility, while the early access model de-risks product development by relying on direct user input.
