Infinity Advisory

Board & Strategic Advisory at the Convergence of Digital Assets, AI & National Security

Gary Weinstein works at the convergence of digital assets, artificial intelligence, and national security, with a particular focus on countering the financing of terrorism. He brings regulatory depth and board-level judgment shaped by a career across government enforcement, financial services, and privacy-preserving technology. He contributes to the international institutions and expert bodies working on illicit finance and emerging technology, serving in an independent capacity distinct from the firm’s commercial advisory work. Alongside that, he advises technology ventures from stealth through public-market readiness, and has served on the boards and advisory boards of companies, government entities, and nonprofit organizations. Commercial engagements run through Infinity Advisory LLC. He accepts select speaking, advisory, and working-group invitations.

By-invitation engagements: briefed a sitting prime minister at a government-sponsored forum; moderated a panel featuring a sitting U.S. member of Congress, a Senate-confirmed federal agency chair, and senior AI executives from Google and Microsoft; and engaged counter-terrorism and law-enforcement officials at the United Nations.

National Security

Countering the Financing of Terrorism

Gary works where emerging financial technology meets national security, with a practical view of how illicit finance can be detected and disrupted without imposing surveillance on legitimate users or adverse consequences on civil society. He contributes this perspective to multilateral bodies, expert working groups, and public-private partnerships, and works to translate complex technical questions into clear, practical terms for mixed audiences of law enforcement practitioners, policymakers, and industry.

Gary Weinstein

Founder, Infinity Advisory

Gary Weinstein founded Infinity Advisory to bring regulatory and national-security perspective into the boardroom and into the institutions shaping digital-asset and AI policy. He is committed to United States national security: he is a member of the Countering the Financing of Terrorism Online working group at the Global Internet Forum to Counter Terrorism (GIFCT), took part in the United Nations 2026 Counter-Terrorism Week, and has written in Forbes on the importance of encryption for the intelligence community. This institutional and expert-body work is carried out independently and is not undertaken on behalf of advisory clients. His work on privacy-preserving technology informs a practical view of how illicit finance can be detected and disrupted without imposing surveillance on legitimate users or adverse consequences on civil society.

Blockchain & Digital Asset Leadership

Gary’s move into blockchain in 2018 led to his role as Head of Global Regulatory Relations for Zcash, where he worked across sanctions, anti-money laundering, and emerging virtual-asset regulation, and advocated for privacy-preserving technology grounded in advanced cryptography. He co-founded and co-hosted the PGP for Crypto video podcast, and is a contributing author to Forbes Digital Assets, where he shares perspectives on global digital-asset regulation and policy. His published analysis of financial privacy has been cited in amicus briefing in Coin Center v. Yellen, a federal court challenge to Treasury cryptocurrency sanctions.

Rule of Law & Enforcement: Former New York Assistant Attorney General

As an Assistant Attorney General in New York, Gary enforced the law in the public interest, protecting consumers and market integrity. He chaired a multistate investigation into a global price-fixing conspiracy impacting over $1 billion in U.S. commerce in coordination with the DOJ and FTC, and defended the State in federal trial and appellate courts. The work grounded his approach in rule-of-law fundamentals: due process, evidentiary rigor, and the limits of enforcement authority.

Executive Leadership in Financial Services

For fifteen years, Gary served as SVP, Deputy General Counsel, and Chief Privacy Officer at a leading consumer financial services firm, overseeing litigation and privacy and guiding compliance across anti-money-laundering and federal and state consumer-finance frameworks, and becoming a nationwide authority on the federal confidentiality statutes governing taxpayer data. He defended the company through DOJ and State Attorney General investigations and was later promoted to Acting General Counsel, advising the CEO and Board during a pivotal period.

Public-Sector, Multilateral & Board Service

Gary currently serves on two government boards and contributes to international expert bodies working on terrorist financing and emerging technology. He has testified before the U.S. Senate Committee on Homeland Security, Permanent Subcommittee on Investigations, filed an amicus brief in a landmark case before the Supreme Court of the United States, and presented at a government-sponsored forum on blockchain and regulation in South-Eastern Europe. He served eight years on the Board of Directors of a national trade association, including terms as Treasurer and Secretary, working with U.S. Senators, Representatives, and the CFPB Director on taxpayer rights and financial access.
