A 90-day growth plan starts with one clear business question — usually tied to revenue or pipeline — then works backward into channels, experiments, and weekly checkpoints, rather than starting with tactics you feel like trying. Structure it in three phases: weeks 1-2 diagnose where the funnel is actually leaking and what's already working, weeks 3-10 run focused experiments on one or two channels, and weeks 11-13 double down on what worked and kill what didn't.
Kando runs this exact cadence with clients inside its Build phase, shipping in two-week cycles so a 90-day plan produces several checkpoints, not one big bet at the end.
