Hi @Tej,
Ideas and strategies presented during Demo Day are designed by GrowthX cohort but these strategies are backed by user calls, input from actual product teams and CEOs of these companies.
In GrowthX, post our 5 week learning sessions, we work on a Capstone project to build implementable strategies and growth plan to scale products by 10x. Teams working on specific products can be considered as an extended growth teams (on steroids) of the respective brand.
While these are not first hand strategies but many of the companies have actually deployed few of the strategies in past.
