Keystone is an innovative economics, technology, and strategy consulting firm helping to solve problems at the intersection of business, technology, and law. Leaders of top-tier law firms, global corporations, and regulatory agencies turn to our 20 years of experience in technology markets to calibrate their perspectives today and help cohere their vision for the future. We combine the strategic insights of leading experts from Harvard, Stanford, MIT, Wharton, and other top universities with the practical industry expertise of our accomplished consulting professionals.

Delivering transformative ideas through uncommon service

Founded in 2002, Keystone has worked at the forefront of influential technology matters changing consumer behavior and impacting society on a global scale. Our team brings an interdisciplinary approach to consulting, leveraging the expertise of our “triad” of focus areas: economics and data science, technology and engineering, and business strategy to deliver transformative ideas through uncommon service.

Since Keystone’s debut on the Global Competition Review’s annual ranking of consulting groups in 2020, we continue to offer a wide array of advisory work to some of the world’s most valuable companies, including digital platforms such as Facebook, Amazon, and Microsoft. We work alongside competition authorities globally including those in the United States, United Kingdom, European Union, Australia, Japan, and Korea.

Keystone’s Antitrust & Competition practice focuses primarily on critical issues facing digital regulation: platform economics, network effects, digital advertising (including technology intermediation, consumer welfare, and targeting), data and privacy, algorithmic competition, ethics and societal values, and general competitive effects of AI and machine learning. Keystone is also increasingly involved in competition matters in the pharma and real estate industries and in prominent merger reviews and merger litigation. Keystone and its academic partners frequently publish innovative research to drive thought leadership and conversations around regulation of AI, competition in technology markets, app store regulations and the importance of data in digital markets.

We greatly appreciate the previous recognitions from the Global Competition Review of Keystone’s unique approach to questions of competition in technology markets. To learn more about our team and our experience, visit
