Did you know that nearly 80% of daily active users of top mobile apps come from ingrained habits? People who open an app like Instagram or TikTok often do so without a conscious thought. This isn’t accidental; it’s the result of a meticulously designed psychological framework known as the Hook Model.

The Hook Model is a four-step cycle—Trigger, Action, Variable Reward, and Investment—developed by author Nir Eyal. It serves as a blueprint for product designers and engineers to build technologies that become an integral part of users’ daily routines, effectively turning casual users into highly engaged, long-term advocates.

Turning a fleeting idea into a market-ready product is a high-stakes game. A staggering 72% of all new product launches fail to meet their revenue targets. The primary culprit? A weak or invalidated concept. Concept development is the strategic process of transforming that initial spark into a concrete, validated blueprint. It’s the architectural phase that ensures you’re building a solution for a real problem, for a specific audience, before you invest a single dollar in development.
