In the last 5-7 years or so - with easy money flowing across startups, there was an active reach out to attract young pedigreed folks for various business/product roles, especially in the home grown startups. A large chunk were absorbed across new verticals and were mandated to build those from scratch. This allowed them to operate at a different vantage point and hence gain a different understanding of the business. This led to accelerated learning for these folks which in turn allowed them to move in leadership roles across multiple organisations in quick succession.
This compounding effect led to much steeper growth for these folks both across work as well as compensation.
However, this has not been the case across matured organisations who are more set in their approaches - Year of Exp, sector/industry exposure, etc etc. There, these guys have seen a much moderated growth both in terms of business exposure/compensation. Still, you can expect a steeper growth curve for them in this setting as well.
