NUCLEUS NOUNS

Summary from the TLDR Founders newsletter

Most apps revolve around one or two nouns, like 'Channel' and 'Message' in Slack and 'Project' and 'Issue' in Linear. These are nucleus nouns, and every other noun is a 'satellite'. Thinking about apps in terms of their nucleus nouns allows developers to cut to the core of what an app is supposed to do. Customers feel it when a company loses sight of its nucleus nouns. Companies with a firm understanding of their nucleus nouns can use them as a weapon by making them part of their brand.
