you meet are the people who do the work.
Co-Founder & CEO
Mark Graves
30+ years in the financial industry — 10+ building and maintaining programs that withstand regulatory scrutiny.
Mark Graves, Esq., CAMS, CRCP, is Co-founder and CEO of 7T World, with more than three decades spanning regulators, banks, and fintechs. He built his career first on the government side — as a financial regulator and enforcement attorney at the state, federal, and international levels, including the U.S. Securities and Exchange Commission, where he earned the Chairman's Award for Excellence — leading examinations and investigations that spanned the international operations of the firms he oversaw, including across the Pacific Rim, and serving as lead attorney on the resulting enforcement matters. He then moved to the industry he had regulated: Global Head of Sanctions and a senior compliance leader at Silicon Valley Bank, and first standalone Chief Compliance Officer at Marqeta through its pre-IPO scale. From there he co-founded and led legal and compliance for a payments company that grew to 13+ countries, 500+ employees, and principal membership in Visa. He has worked in digital assets for more than a decade — building the compliance and risk controls behind stablecoins, tokenized settlement, and cross-border payments from the earliest days of crypto-banking.

Co-Founder & COO
Anthony Serio
The governance layer that makes new payment rails examination-ready — the controls, not the hype.
Anthony Serio is Co-Founder and COO of 7T World — an operator, not a theorist. A U.S. Navy veteran with 25+ years across FX, payments, and risk, he has run the front, middle, and back office at major institutions and fintechs. His career runs from Brown Brothers Harriman — the oldest private bank in the U.S. — through Wells Fargo, where he traded FX, and East West Bank, where he was First Vice President and Director of FX Operations, to Silicon Valley Bank, where he led enhanced due diligence on the bank's earliest digital-asset clients — including Circle and Coinbase, before they jointly launched USDC — and authored the bank's enterprise Product Risk Controls Catalog. He later led payments, risk, and operations across fintechs — as interim Chief Payments Officer at ARB Interactive and Head of Operations at Sila — and stood up risk and compliance as interim Chief Risk Officer at a stablecoin-to-fiat settlement platform. He is also the founder of Serio Payments Consulting, now part of 7T World, which helps banks, processors, and fintechs untangle ACH, FX, cross-border treasury, and full-stack risk. Anthony chairs the Financial Inclusion Work Group at the U.S. Faster Payments Council, helped author 7T's formal comment on federal stablecoin rulemaking, and works at the front edge of stablecoins, tokenized deposits, and instant payments.

25+ years building systems that balance sophisticated technology with regulatory rigor.
Sonjaya Tandon is CTO & Chief AI Officer of 7T World, with 25+ years of technology leadership at enterprise scale. A Cornell-trained computer scientist and former McKinsey Associate Partner — where he led product and engineering for a financial-services practice — he is a strategist who still writes production code.

Managing Director
Sophie Forbes
Turning deep expertise into solutions institutions can understand, adopt, and put to work.
Sophie Forbes is Managing Director of 7T World — a serial entrepreneur and commercial operator who has built, scaled, and successfully exited two companies. She began her career by founding an international textiles business, growing it over several years before completing a successful exit and earning her MBA. She then launched a company in the furniture industry, scaled it to serve major national and global accounts, and sold it to a multinational corporation. Sophie subsequently led international sales for an electronics company serving military and government customers around the world, repeatedly finishing as its top sales representative. Most recently, she led sales for a manufacturer and served as the principal relationship lead for one of the world's largest companies — a multinational ranked among the top 15 of the Fortune 500. Across industries, Sophie has built businesses, navigated complex enterprise buying environments, and converted sophisticated offerings into durable commercial relationships. At 7T World, she leads strategy, sales, and business development — helping translate regulatory, operational, and technical expertise into solutions that financial institutions can understand, adopt, and put to work.
