Before his first cup of coffee, Alex Melamud opens Slack—not to scan revenue charts first, but to read customer feedback. “The first one that may surprise you as a CFO that I look at is actually NPS,” he tells us. At Engine, every survey drops into a shared channel so “every executive can see” what customers said, he tells us.

That habit fits a finance leader who didn’t grow up in the CFO seat. Melamud started in investment banking and then spent 16 years in private equity, learning to build theses, chase signal, and “sell… the product of private equity,” he tells us. Sitting on boards, he watched the CFO role evolve from “corporate governance accounting” into “executive first and maybe CFO second,” he tells us—someone who can talk like product, sales, or operations and earn board trust.

Engine became the moment he stepped inside. After leading the company’s round “18 months ago,” joining the board, and helping with a CFO search, he looked at founder “Eli” and asked, “what if I joined you as CFO?” he tells us. The draw was a focused mission: serving SMB travel, where customers book “like a consumer” and lose corporate rates and visibility, he tells us.

Now his investor lens shows up in the unglamorous work. During annual planning, he dug into the “top 50 costs” outside headcount and pushed leaders to treat each contract “as a brand new relationship,” he tells us—an inspection that produced “10, 15%” savings and “tens of millions of dollars,” he tells us.
