Rafael Ortiz
Writer and researcher, One Plata
Rafael Ortiz is a patient explainer from Arizona. For years he was the person family and friends called before signing anything — a lease, a car loan, a first credit card — because he'd read the fine print, look up the actual rule, and translate it into plain English. Eventually he started writing the explanations down. That's One Plata.
Rafael isn't a financial advisor, a banker, or a lawyer, and he doesn't pretend to be. What he does instead is slower and, he'd argue, more useful: he reads the primary sources — CFPB, IRS, FDIC, SSA, FTC, state statutes — and links them so you can check every claim yourself. He never recommends products and never gives advice. He explains how the system works and lets you decide.
