Building a functional loop marketing system takes roughly 90 days from start to first optimization cycle. The first 10 days cover foundation work: ICP definition, company context collection, and brand belief documentation. Days 10 through 60 cover AI agent building and initial content production. Days 60 through 90 run the first data review. Most teams have at least one full campaign live within three months and two campaigns running by month six. The 90-day timeline assumes a team that can clearly articulate the problem it solves, its solution, its differentiators, and its results. Companies still refining product-market fit will need longer on the Express stage alone. Setup requires two to three weeks of concentrated effort on brand context documentation, ICP definition, and initial agent building before any content production begins. Within the first four to six weeks, most teams see noticeable gains in production speed and early engagement. By the three-to-six-month mark, improvements compound: all core assets (product pages, FAQ, on-site blog content, off-site answer campaigns, ICP segments with tailored experiences, segment nurturing workflows, and social posts) reach a solid effectiveness level, and there is enough performance data to run meaningful quarterly optimization cycles. ### Ask AI about Lean Labs [
