About Marcio Barreto
About
Marcio Barreto is a Global Finance Executive managing $260 million in operations across multiple countries.
Over two decades, he has held finance leadership roles spanning Big Four consulting, Fortune 500 companies, and private equity, giving him a rare perspective on how different organizational systems operate—and why some build clarity while others generate noise.
He writes The Clarity Letter, a weekly Substack newsletter on organizational clarity and anti-productivity theater for leaders tired of drowning in meetings, metrics, and garbage work that looks productive but compounds nothing.
His book THE EFFICIENCY TRAP addresses the specific moment where AI makes execution free, organizations demand more output, and judgment atrophies from lack of practice. It provides diagnostic frameworks for leaders at every level—from individual contributors protecting their own clarity to executives redesigning systems that currently select for chaos.
Marcio has appeared on The WealthAbility Show with Tom Wheelwright and actively engages with finance and operations leaders on LinkedIn, where he explores the gap between what organizations measure and what actually matters.
Outside finance and writing, he coaches youth soccer and tests recipes on a patient family.
