Dr. Mark Green

Dr. Mark Green

Chief Executive Officer

Dr. Mark Green spent two decades in the Army, graduating from West Point and serving as a flight surgeon with the 160th Special Operations Aviation Regiment, the Night Stalkers, in Afghanistan and Iraq. He participated in Operation Red Dawn, the mission that captured Saddam Hussein, and interrogated Saddam for six hours that night, later writing the book about it, A Night with Saddam. He went on to build an emergency medicine company to more than $200 million in annual revenue across 52 hospitals in 11 states, then represented Tennessee's Seventh District in Congress from 2019 to 2025 and chaired the House Committee on Homeland Security, at the centre of national debates over cybersecurity, critical infrastructure, supply chains and strategic competition with China. At Bifrost he connects decisions made in Washington to their consequences across compute, power, materials and capital markets.

A graduate of the United States Military Academy at West Point, he began his career as an Army infantry officer before earning his medical degree and returning to service as an emergency physician. He later served as a flight surgeon with the Army's 160th Special Operations Aviation Regiment, the Night Stalkers, planning and flying some of the War on Terror's most covert operations across Afghanistan and Iraq.

On 13 December 2003 he participated in Operation Red Dawn, the mission that captured Saddam Hussein, and interrogated Saddam for six hours that night. He published the account as A Night with Saddam. For his service he was awarded the Bronze Star, the Air Medal with Valor Device and the Combat Medical Badge.

After two decades of military service he founded and built an emergency medicine management company that grew to more than $200 million in annual revenue, serving 52 hospitals across 11 states, before selling the business into a physician-services platform backed by Goldman Sachs. He also founded clinics providing free medical care to underserved communities.

He entered public service in 2012, serving in the Tennessee Senate before representing Tennessee's Seventh Congressional District in the United States House of Representatives from 2019 to 2025. As Chairman of the House Committee on Homeland Security he worked at the centre of national debates over cybersecurity, critical infrastructure, supply chains, border security and strategic competition with China.

At Bifrost he connects decisions made in Washington with their consequences across compute, power, infrastructure, critical materials and capital markets: understanding the entire system, identifying where its constraints are moving, and investing where national priority becomes economic reality.

Christian Briggs

Christian Briggs

Chief Investment Officer

Christian Briggs has spent four decades in physical markets. He is the founder and chief executive of Hard Asset Management, where he has bought and sold several hundred million dollars of rare coins and precious metals for family offices, institutions and governments, advising clients on what to acquire and when to hold or sell it. Before metals he founded Cinsay, later AiBUY, and developed interactive video commerce more than a decade before Instagram Shopping and TikTok Shop, producing 100 U.S. patent filings and 43 granted patents across nine inventions. He advises the White House, Senate and Congress on geopolitics and financial policy. At Bifrost he holds final portfolio authority and leads the firm's research into physical supply and the constraints beneath the artificial-intelligence buildout.

He has been active in hard assets since 1987, holding executive positions at several rare coin and precious metals companies before founding Hard Asset Management. The firm specialises in the procurement and placement of rare United States and world coinage for wealth preservation, and works on explicit recommendations of what to buy, when to buy it and when to sell. Its principals have transacted close to $500 million in rare coins and precious metals worldwide and participate actively at the major auction houses. In the late 1980s and 1990s Briggs was a substantial buyer of early Russian gold and platinum rouble coinage. He is a Life Member of the American Numismatic Association and the Florida United Numismatists.

He founded Briggs Digital Media in 2007 and filed the provisional application underlying the business in January 2008, almost three years before Instagram launched. The technology placed a working storefront inside the video player itself, allowing a viewer to buy without leaving what they were watching. The company was renamed Cinsay and later AiBUY, growing to more than 120 employees across Austin, Dallas and Los Angeles, and was named by Forbes to America's Most Promising Companies. The patent estate runs to 100 U.S. filings, 43 of them granted, across nine separate inventions.

Cinsay sued Brightcove, Joyus and Liveclicker for patent infringement in the Northern District of Texas in 2013, settling with Brightcove, then a publicly traded company, under a confidential patent licence the following year. Parallel families were published in China, Russia, Europe, Mexico and through the PCT system, including granted patents at both CNIPA and Rospatent, offices that treat business methods as unpatentable subject matter. A 2012 application describes two shoppers on separate devices sharing a single cart and a live chat window. The Smart Store™ technology detects the viewer's device, adjusts its rendering and geography, and copies itself across social networks while carrying affiliate attribution down the chain. An application filed in February 2014 claims a sensor that measures interest through eye movement without requiring a click, together with the use of a blockchain ledger for advertising attribution.

He hosts On the Record with Christian Briggs, which airs Wednesdays on America Out Loud Talk Radio and is carried on podcast networks worldwide. He has interviewed Senator Bill Hagerty of the Senate Banking Committee on central bank digital currency and Thomas Fuentes, former Assistant Director of the FBI, on global escalation, and appeared on a FreedomWorks panel in Washington with Congressman Mark Green and former Treasury Assistant Secretary Monica Crowley. His three-part policy series examines China's pressure on dollar hegemony through banking infrastructure, critical mineral supply and the mechanics of de-dollarization. He has also produced three feature films, as executive producer on The Acquirer and Dan's Detour of Life and as producer on One Nation Under God, and raced the Ferrari Challenge series to its North American championship in 2000.

At Bifrost he applies four decades of pricing scarce physical assets to the constraints beneath the artificial-intelligence buildout. The work is the same in structure: establishing what a limited supply is genuinely worth against the demand placed on it, identifying where that gap is widest, and holding a position until the market reprices it. He holds final portfolio authority and will invest his own capital alongside the firm's investors.

How We Work

The Chief Investment Officer holds final portfolio authority, but every thesis is argued in front of the whole table before capital is committed. Each position carries a written list of the observable events that would end it; trims follow impairment of the thesis, not price movement alone. The general partners invest their own capital alongside investors.
