Evan Armstrong
Evan Armstrong writes about profit and power in technology. He spent four years as lead writer at Every, where his column Napkin Math turned finance terms like revenue, COGS, and net income into deeply reported, deeply funny explainers for an audience of more than 100,000. In April 2026 he walked away to launch The Leverage, a solo publication promising rigorous, actionable, beautiful analysis of tech markets for founders, investors, and senior operators. He had never been paid to write before joining Every, and went on to publish almost 500,000 words there.
