Since 1989, Cornerstone Research has been the firm that attorneys, corporations, and government agencies turn to when the stakes are highest. We provide rigorous economic and financial analysis and expert testimony across all phases of commercial litigation and regulatory proceedings. With more than 1,000 professionals across nine offices in the US, UK, and Belgium, we bring together an exceptional internal team and an extensive network of leading academics, former regulators, and industry practitioners — each carefully matched to the unique demands of every case.

We are a team of economists, financial analysts, statisticians, and data scientists who thrive on solving the most complex analytical problems in the legal arena. Our culture of growth and collegiality creates a dynamic work environment where team-based casework, individual initiative, and cross-disciplinary collaboration go hand in hand. From our founding — by leaders who believed deeply in academic rigour and a collegial workplace — we have built a firm where every professional has the opportunity to work alongside and learn from world-class colleagues and experts. Our four core values define not just how we work, but who we are: Dedicated to Quality, Committed to Clients and Experts, Committed to Our People, and One-firm Firm.

We provide economic and financial consulting and expert testimony across more than 20 practice areas — from antitrust and competition to securities litigation, intellectual property, valuation, and beyond. Whether quantifying damages, analysing market dynamics, modeling financial distress, or assessing the economic impact of corporate decisions, our consultants deliver data-driven insights that hold up under the most exacting scrutiny in courtrooms and regulatory proceedings worldwide. We work with parties in US federal and state courts, the SEC, FTC, DOJ, and international arbitration tribunals.

Our purpose is to ensure that every client — law firm, corporation, or government agency — enters the most complex legal and regulatory proceedings with the strongest, most credible economic analysis available. We exist to bridge the gap between cutting-edge academic research and the practical demands of litigation, delivering insights that make a decisive difference.

Dedicated to Quality: We provide rigorous, objective, and state-of-the-art analysis in everything we do. Committed to Clients and Experts: We invest deeply in understanding each case and supporting every expert we work with. Committed to Our People: We foster a culture where every professional can grow, contribute, and thrive. One-firm Firm: We operate as a single, unified organisation — staffing matters across offices and practice areas to bring the best of the firm to every client.

We are the market leader in economic and financial consulting for securities class actions and among the most recognised firms in antitrust, intellectual property, and regulatory matters globally. Our unique model combines an exceptional internal professional staff with an unmatched network of prominent academics and industry practitioners — giving clients access to the most qualified expert for every assignment. With nine offices, more than 1,000 professionals, and a 35-year track record of delivering rigorous, state-of-the-art analysis, we are the firm that major law firms trust when navigating the highest-stakes disputes in the US, UK, EU, and beyond.

Cornerstone Research is proud to sponsor organisations committed to equal access to opportunity and inclusion.

Our long tradition of inclusivity is reflected in our sponsorships, our community partnerships, and the culture we build every day. We seek opportunities to celebrate diversity and encourage employees to share and learn from one another. By embracing and celebrating differences, we foster an environment where all employees are encouraged to contribute authentically. We have received the Equality 100 Award from the Human Rights Campaign Foundation's Corporate Equality Index, a recognition of our commitment to LGBTQ+ workplace equality.
