The Curriculum

Mark Agustin is a personal finance writer and the founder of KatchingStacks. He holds a Bachelor's degree in Business Management and came to personal finance the hard way — through firsthand financial hardship that made the gap between what schools teach about money and what actually matters in real life painfully clear. That experience drove him to spend years researching the tools, platforms, and strategies that genuinely help people build financial stability from scratch — robo-advisors, index funds, retirement accounts, and the compound math that works quietly in the background when everything else feels uncertain. Every review and guide on KatchingStacks reflects that same ethos: research-backed, jargon-free, and written for the person who doesn't have a financial advisor and doesn't plan to get one. Mark evaluates each platform on fees, portfolio construction, and real-world usability — not affiliate payouts. He is not a licensed financial advisor, and nothing on this site constitutes personalized investment advice. It's the research he does to make better decisions with his own money, shared plainly.
