About the speaker

Martin Stone is CEO of Conversion Rate Experts (CRE), the world’s leading conversion rate optimization agency, and author of The Pocket Guide to Growth.

Martin began his career as an award-winning aerospace engineer, optimizing some of the most advanced aircraft ever built. In that world, margins for error are vanishingly small, and the smallest gains in efficiency or performance can have an outsized impact on outcomes. Working with data, experimentation, and precision engineering, he learned how to find measurable improvements in systems that were already operating at the edge of what was thought possible—a discipline of rigor that would later define his approach to business.

He now applies those same principles to helping companies grow faster and more profitably, replacing guesswork with evidence and intuition with testing. His new book distills this thinking into a short, practical guide for CEOs and founders, drawing on two decades of work with market leaders including Google, Amazon, Apple, and Facebook.

Over the past two decades, CRE has helped increase the profits of some of the most sophisticated companies in the world. Its client list includes Silicon Valley giants such as Apple, Amazon, Meta, and Google; global brands including Sony, Vodafone, and Dell; and high-growth companies such as Huel, MyFitnessPal, and SimpliSafe. Many of these companies have gone on to adopt CRE’s own methodology internally. In recognition of this influence, the company received one of the world’s most prestigious business awards for codifying the scientific approach that companies like Google and Amazon now use to improve their websites. That methodology—combining customer research, rigorous data analysis, and structured A/B testing—has generated billions of dollars in additional revenue for clients across more than 80 industries and 40 countries.

Since stepping into the CEO role in 2023, Martin has led CRE through its strongest period of growth to date, culminating in its most successful year yet in 2025.

Martin is a committed advocate for the idea that sustainable business growth isn’t a product of opinion or guesswork, but of understanding customers deeply, forming testable hypotheses, and letting evidence—not intuition—decide what works. In his talks and writing, he shares the principles and real-world lessons behind a methodology that has helped some of the world’s most successful companies grow through better decisions, not more guesswork.
