You’ve probably seen the name Moore A Series LLC pop up on a donor disclosure or a state fundraiser registry and wondered if it’s a law firm, a real estate holding group, or some kind of mysterious corporate umbrella. Honestly, it’s a bit of all those things, but specifically, it is the legal engine behind some of the largest nonprofit fundraising campaigns in the United States.
It isn't just a company; it's a structure.
Most folks get tripped up by the "Series LLC" part. They think it's a typo. It’s not. In the world of high-stakes marketing and data, this specific entity—headquartered at 4200 Parliament Place in Lanham, Maryland—functions as a professional solicitor for heavy hitters like the American Cancer Society, the ACLU, and the AARP Foundation. If you've received a mailer or a digital plea for a major cause lately, there is a very high statistical probability that Moore A Series LLC was the "invisible" hand moving the gears in the background.
Why the "Series" in Moore A Series LLC Actually Matters
To understand why they chose this structure, you have to look at how a Series LLC works. Basically, it’s like a filing cabinet. The "Master LLC" is the cabinet itself, and each "Series" is a drawer. Each drawer can hold its own assets and—more importantly—its own liabilities.
For a company like Moore, which manages over $1 billion in revenue and employs thousands of people, this isn't just about organization. It’s about "firewalling" risk.
If one specific fundraising campaign for a client hits a legal snag or a contract dispute, the "firewall" prevents that liability from burning down the entire building. In states like Delaware or Oklahoma, where these structures are common, each series can sue, be sued, and enter into its own contracts. It’s a sophisticated way to manage a massive portfolio of nonprofit clients without letting one bad apple spoil the whole bunch.
The Scale of the Operation
We aren't talking about a small boutique agency here. Moore is a data-driven constituent experience management (CXM) giant. They’ve swallowed up dozens of smaller firms—like Thompson Habib Denison (THD)—to create an integrated monster that handles everything from "neuro-fundraising" labs to massive direct mail campaigns.
- Employee Count: Over 3,000 to 5,000 across their various "drawers."
- Key Figures: Led by CEO Gretchen Littlefield (formerly of Infogroup).
- Core Clients: American Heart Association, Arthritis Foundation, and Anti-Defamation League.
What Really Happened With the Moore Rebrand?
For a long time, the industry knew various pieces of this company by names like Moore DM Group. But they’ve spent the last few years aggressively consolidating. They didn't just want to be a mail house; they wanted to own the data, the creative, and the digital delivery.
The transition to the "Moore A Series LLC" designation in regulatory filings reflects this "unified brand" strategy they've been pushing since 2022. They’ve basically stopped acting like a collection of separate companies and started acting like one massive, segmented entity.
It’s efficient. It’s also a bit intimidating if you’re a smaller nonprofit trying to figure out who is actually handling your donor data.
The Privacy and Data Question
Here is what most people miss: Moore A Series LLC isn't just asking for money; they are harvesting intent.
Through their SimioCloud platform, they use data science to predict who is likely to give and when. When you see "Moore, a Series LLC" on a professional fundraiser search in Minnesota or California, you're looking at the entity that holds the legal responsibility for how that data is used during a campaign.
Some critics argue that the Series LLC structure makes it harder for the public to track exactly where money is flowing between different units. However, proponents say it's the only way to manage the sheer complexity of modern, multi-channel fundraising across 50 different sets of state laws.
Is it a "Real" Company?
Yes.
Sometimes people search for this name thinking it's a scam because they see it on a credit card statement or a disclosure. It’s a legitimate, massive corporate entity. They are a "Professional Fundraiser" (PFR), which means they are hired by charities to do the heavy lifting of asking for donations. They don't keep the money—mostly—but they do take a fee or a percentage for their services, which is why their name appears on the legal paperwork.
Actionable Insights for Nonprofits and Donors
If you’re a nonprofit leader or a curious donor, don't let the complex name scare you off, but do your homework.
- Check the Contracts: If you're a nonprofit hiring an entity under the Moore umbrella, realize that you are entering a world of "segmented liability." Ensure your specific "series" is clearly defined in the service level agreement.
- Look for the PFR Number: If you see Moore A Series LLC on a mailer, you can look up their specific registration number in your state's Attorney General database. This will show you exactly what percentage of funds raised actually went to the charity in previous years.
- Data Opt-Outs: Because Moore uses high-level modeling (like SimioCloud), if you want to stop getting mail from all their clients, you often have to go through the DMAchoice service or contact Moore’s privacy officer directly at their Lanham HQ.
The reality of 2026 fundraising is that it’s no longer about a guy with a clipboard. It’s about massive, legally-armored structures like Moore A Series LLC using petabytes of data to find the right donor at the right time. Understanding the "drawer" system they use is the first step to knowing how the modern "giving" machine actually works.
