The evidence-based model of brand growth built an entire doctrine – and a consulting cottage industry – on that 7%. Identify the category entry points. Build distinctive assets. Maximize reach. Drive penetration.
None of that is wrong. It’s just not strategy. It’s execution. And AI is about to make the difference impossible to hide. 87% of marketers now run generative AI weekly, up from 51% two years ago. It already finds the CEPs. Tests the distinctive assets. Generates the creative. Optimizes the media buy in real time.
7% of corporate growth comes from taking market share. (McKinsey) The rest comes from where companies chose to compete.
The entire penetration playbook is turning into software – a feature running quietly inside every ad platform, not a strategy anyone gets credit for. You can already see it in the headcount data: 23% of agencies cut junior copywriters last year. 31% plan more cuts this year. Autonomous agents running full campaigns more than doubled in two quarters. Execution is getting commoditized in real time.
Meanwhile, the McKinsey data on category-creating industries – cloud, e-commerce, biopharma, EVs – shows them growing revenue at 10% a year against 4% for everyone else, nearly tripling their share of market cap. Nobody got there by improving penetration inside a category that already existed. They got there by deciding a new one should.
So: 75% of marketers have no AI roadmap. Only 49% can measure what their AI spend is even doing.
When execution is free, the only thing left to compete on is the choice AI can’t make for you – what demand to create, which category to own, what you refuse to become. Reach, availability, and penetration aren’t going away. They’re becoming the operating system everyone gets by default.
Strategy was never about running that system well. It was about deciding what runs on it.
