How the term shows up here In the channel's material on building AI products and startups, C change is used the way its homophone sea change is used in ordinary English: a fundamental transformation in the conditions an industry operates under, not an incremental improvement. It appears in the context of the current AI moment — a shift large enough to change which strategies win, such as business model innovation beating product innovation and startups counter-positioning against far better-funded incumbents. Use the term when you want to name that scale of shift, not a feature release or a trend. Keep it bolded on first use and italicized as a term of art: C change.
