What are real examples of small teams running big-league paid campaigns with AI?
The short answer
Cal AI's teenage founders scaled a calorie app past $2M a month on influencer-style paid content, Arcads bootstrapped to $10M ARR running more AI agents than employees, and Zepto doubled app installs using Google's Veo to turn static product images into video ads. The common pattern is tiny teams using AI for creative volume and campaign execution while the founders keep judgment over offer, hooks, and distribution. None of them outsourced strategy to the machine.
A quick orientation. The real value is below: resources worth your time, from people who've actually done it.
