EarlyRetirementNow.com is an influential personal finance blog founded and run by Karsten Jeske, Ph.D., a former economist and asset manager. Launched in 2016, the blog's mission is to provide rigorous, data-driven analysis on topics crucial for early retirement, with a particular focus on its highly-regarded "Safe Withdrawal Rate Series." The content is educational and analytical in nature, aimed at helping readers make informed decisions about their retirement finances, rather than providing direct financial services or advice.
