For a great product growth hacking strategy, there are 2 main concepts you should master them.
Windows of Opportunity (WoO)
A time when your target end user, economic buyer, champion, or influencer will be particularly open to considering your offering, Examples:
• Holiday Season
• End of Fiscal Year or Beginning; Budgeting Cycle

• Change in Leadership
Within the WoO, a specific action you take to create an urgency/strong incentive for the target customer to act, Examples:
• Limited supply
• Time bounded
• Avoid disaster
