Move from the core purpose of growth through a self-reinforcing loop to a concretely designed user hook.
A growth model aligned with the core purpose, with an identified reinforcing loop and a concretely designed user hook.
You can decide which step in the flywheel is reinforced next.
Set up the designed hook as a growth experiment and measure its effect on the flywheel loop.
Which Why becomes credible through our How principles and What?
Without a clarified core purpose, growth actions stay interchangeable and without a recognizable direction.
The clarified core purpose determines which reinforcing loop is sought in the business model.
Which repeatable sequence of a few components creates customer value, pushes each next step, and gains measurable momentum through consistent turns?
The flywheel shows which step in the business model reinforces the next, instead of just growing linearly.
For the weakest step in the flywheel, a concrete user hook is designed.
Which responsible usage loop repeatedly helps users solve a real problem?
The hooked model translates the abstract reinforcing loop into a concrete, testable user cycle of trigger, action, reward, and investment.
The designed hook is tested as a concrete growth experiment.
Artifacts stay collapsed until you actually need them.
Select one team or offering and collect three concrete situations where its work made a difference.
