From Olympic Doping to Horse Racing Corruption, Human Trafficking to High-Profile Police Audits, 5Si Proves Integrity-Driven Intelligence Still Has An Ally
MIAMI–(BUSINESS WIRE)–In an era defined by complex threats, global scandals, and growing distrust in institutions, 5 Stones intelligence (5Si)®, a leading international intelligence and investigations firm, has emerged as a trusted partner for those seeking truth, accountability, and protection. Founded in 2007 by former DEA Miami Supervisory Special Agent David tinsley, the Miami-based agency has played a decisive role in some of the world’s most headline-making investigations.
“Our foundation is truth, integrity, and discretion, and from inception, we built 5Si to do what others could not or would not,” said 5Si Founder David tinsley. “We are not just another investigations firm; we are the people governments, corporations, and communities trust most to turn to when the mission is complex, the stakes are high, truth matters most, and failure is not an option.”
In 2016, 5Si partnered with U.K. NGO STOP THE TRAFFIK to launch the STOP App, the world’s first app to combat human trafficking, and target this very personal form of terrorism. The app, developed and funded by 5 Stones, empowers ordinary citizens to securely report trafficking activity in real time, creating “ground truth” intelligence for law enforcement and NGOs worldwide.
“At 5Si, we’ve always believed intelligence shouldn’t just expose corruption — it should also protect the vulnerable,” said 5Si Founder tinsley. “The STOP App reflects our mission to apply world-class intelligence tradecraft to humanitarian challenges.”
5Si’s expertise has been enlisted in some of the most consequential sports integrity scandals of the modern era. Retained by the World Anti-Doping Agency (WADA), the firm was described by outlets including The Washington Post and Bloomberg as playing a “central, secret role” in exposing Russia’s state-sponsored Olympic doping program — an investigation that reshaped international sport and dominated headlines worldwide.
In the U.S., 5Si’s covert work for The Jockey Club and racing reform advocates provided the leads that enabled FBI wiretaps and federal indictments of elite thoroughbred trainers in horse racing’s 2020–2021 doping crackdown. Nearly 30 individuals were charged and convicted, as the case became a catalyst for the Horseracing Integrity and Safety Act, placing the billion-dollar industry under federal oversight for the first time.
“Integrity in sport isn’t just about fair play — it’s about restoring public trust,” said 5Si Chief of Staff Matthew Tinsley. “Our work proved that even entrenched systems can be challenged when truth is pursued relentlessly.”
Most recently, 5Si’s credibility as a neutral arbiter was called upon in the Karen Read retrial in Massachusetts. Commissioned by the Town of Canton, the firm conducted an independent 206-page audit of the police department, identifying serious investigative missteps but finding no evidence of a conspiracy to frame Read. Released publicly on the first day of jury selection, the audit highlighted 5Si’s role as a trusted partner in safeguarding truth and accountability when public trust is at stake.
Beyond these headline-making missions and remaining a silent yet steadfast force behind the scenes, 5 Stones intelligence continues to deliver government-grade investigative, financial, and protective intelligence services to agencies, corporations, law firms, and communities worldwide. As a prime contractor on the U.S. Department of Justice’s Asset Forfeiture Investigative Support Services programs (AFISS-1 and AFISS-2), with active multi-million-dollar task orders across DOJ agencies, including the IRS, ATF, DEA, the State Department, and FBI, 5Si operates with the credibility of a government partner and the agility of a private firm.
Staffed by over 200 elite professionals from the DEA, FBI, CIA, ATF, IRS, HSI, London’s Metropolitan Police, NCA, Navy SEALs, Delta, MARSOC, U.S. Special Operations Forces, and Israel’s Unit 8200, 5Si operates the world’s largest private HUMINT network—providing mission-critical intelligence with integrity, discretion, and international reach—supported by teams in 44 U.S. states as well as London, England and Jerusalem, Israel.
“Truth, accuracy, and discretion aren’t just values—they’re our operational standard,” said 5Si Founder David tinsley. “What defines us isn’t the noise around the headlines. It’s the fact that when the stakes are high, and governments, corporations, and communities face their hardest battles, 5Si delivers clarity, integrity, and results—quietly, and without compromise.”
