When you start a company, you usually focus on product market fit or finding your first ten customers. You probably do not spend a lot of time thinking about the United States Department of the Treasury. However, if you plan to operate a business that touches the global economy, the Sanctions List managed by the Office of Foreign Assets Control, or OFAC, is something you need to understand.
At its core, the Sanctions List is a directory of individuals, companies, and groups that the United States government has identified as bad actors. These entities might be involved in terrorism, international narcotics trafficking, or activities that threaten national security. The list also includes people acting on behalf of countries that are subject to broad economic sanctions. For a founder, this list represents a boundary that you cannot cross without facing severe legal consequences.
Dealing with anyone on this list is generally prohibited for U.S. persons. This definition of a U.S. person is broad. It includes U.S. citizens, permanent resident aliens, any person located in the United States, and any entity organized under U.S. laws. Even if your startup is a small remote team, if you are incorporated in the United States, these rules apply to every transaction you make.
Understanding the Scope of the SDN List
#The most common part of the OFAC registry that people refer to is the Specially Designated Nationals and Blocked Persons List, often called the SDN List. This is a living document that changes frequently. It includes names of individuals and companies owned or controlled by targeted countries. It also lists individuals and entities that are not country specific. These might be cyber criminals or proliferators of weapons of mass destruction.
When a person or entity is placed on the SDN List, their assets within U.S. jurisdiction are blocked. This means you cannot pay them, you cannot receive money from them, and you cannot provide services to them. For a software startup, this means you cannot let them subscribe to your platform. For a hardware company, you cannot ship them a physical product.
It is important to note that OFAC does not just provide one list. They manage several different types of sanctions programs. Some are geographic, meaning they target entire countries like Iran or North Korea. Others are list based, meaning they target specific individuals regardless of where they are located. As a founder, you must navigate both the broad country bans and the specific individual names on the SDN List.
The Concept of Strict Liability
#One of the most daunting aspects of OFAC compliance for a startup founder is the principle of strict liability. In many areas of the law, you have to intend to commit a crime to be punished. With OFAC, your intentions often do not matter. If you process a transaction with a person on the Sanctions List, you have committed a violation.
It does not matter if you did not know they were on the list. It does not matter if you are a small company with no legal department. The law assumes that you have done your due diligence before moving money or providing services. This creates a significant administrative burden for young companies that are trying to move fast.
This raises an interesting question for the modern entrepreneur. How can a small team with limited resources effectively screen every user or vendor? There is no legal minimum size for a company to be exempt from these rules. Whether you have one employee or ten thousand, the requirement to avoid sanctioned parties remains the same.
Comparing Individual Sanctions and Sectoral Sanctions
#Not every entry on a list means a total ban on all interaction. It is helpful to compare the SDN List with the Sectoral Sanctions Identifications List, or the SSI List. While the SDN List usually results in a complete block on all dealings, the SSI List is more nuanced.
Entities on the SSI List are subject to specific restrictions rather than a total freeze. For example, you might be prohibited from dealing in new debt or equity with a company on the SSI List, but you might still be allowed to sell them a software subscription. This creates a layer of complexity for startups in the fintech or lending space.
Understanding the difference between these two is vital. If you rely on a simple automated tool, it might flag someone on the SSI List and cause you to turn away a legitimate customer. Conversely, if your tool is too lax, you might miss an SDN entry and face a massive fine. The challenge lies in finding a balance between risk mitigation and operational efficiency.
Practical Scenarios for Startups
#Founders often encounter OFAC issues in three main areas: hiring, investment, and customer onboarding. In the hiring phase, you might find a talented developer living in a region with complex geopolitical ties. Before you send that first payroll payment, you must ensure they are not an SDN or acting on behalf of a sanctioned government.
Investment is another critical area. When you are raising a seed round or a Series A, you must know who is actually behind the venture fund or the angel group. If a sanctioned individual owns a significant portion of the fund that is investing in you, your company could be at risk. This is where you have to look beyond the name on the contract and understand the beneficial ownership.
Customer onboarding is perhaps the most common friction point. If you run a SaaS company that accepts credit cards, you are likely using a payment processor like Stripe or PayPal. While these processors do their own screening, the ultimate responsibility for who uses your platform still rests with you. If you provide a service that assists a sanctioned entity in their operations, you could still be held liable even if the payment was processed successfully.
The Unknowns and the Fifty Percent Rule
#There is a specific rule that often catches founders off guard. It is known as the Fifty Percent Rule. This rule states that any entity owned 50 percent or more in the aggregate by one or more blocked persons is itself considered blocked. This applies even if the entity is not specifically named on the OFAC list.
This creates a major blind spot. You could run a search for a company name, find no results on the SDN List, and still be in violation if that company is owned by several people who are on the list. This requires a level of investigative work that most startups are not equipped to handle. It forces us to ask: how far down the rabbit hole must a founder go to be safe?
We also face the unknown of evolving technology. As decentralized finance and anonymous payment methods grow, the ability of OFAC to track transactions changes. This creates a shifting landscape where the rules stay the same but the methods of enforcement and the ways to accidentally violate them multiply. Founders must decide how much they are willing to invest in compliance software versus taking the risk of a manual, and potentially flawed, process.
Navigating these lists is not about being scared. It is about being professional. Building a remarkable business that lasts requires a foundation of integrity and legal awareness. By understanding these terms now, you can build systems that grow with you and prevent a regulatory mistake from ending your journey before it truly begins.
