We built The Stack to make behaviour change plug-and-play.

A online deck of drag-and-drop tactics, it lets teams solve behavioural problems quickly, practically, and with rock-solid science... no training required.

Lauren Kelly created BehaviourKit to remove the guesswork from behaviour change. After one breakthrough product, the Change Behaviour Kit, she doubled down and distilled 300+ studies into The Stack. So any team can spot friction, drop a proven move, and ship the fix the same day.

Today, thousands of professionals use BehaviourKit to find clarity, spark ideas, and deliver results.
