My name is Sandy Seago. I've been in the out-of-home advertising industry for over 20 years. I've worked with billboard operators, transit media companies, and OOH networks across the country. I've seen the business from the inside — the deals, the relationships, the growth, and the cash flow challenges that come with operating in an industry where your customers pay slowly by design.
That last part — the cash flow challenge — is what led me to MediaMark Factoring. After two decades watching OOH operators run excellent businesses while constantly struggling with the gap between when they did the work and when they got paid, I decided to do something about it.
What I Do at MediaMark Factoring
As Chief Revenue Officer of MediaMark Factoring, I work directly with OOH operators to purchase their outstanding invoices and provide immediate cash. The process is straightforward: you post a campaign, you submit your invoice to us with proof of post, and we advance 85–90% of the invoice value within 72 hours. We collect from the agency. You move on.
This is not a loan. It's an asset purchase — we buy the receivable at a small discount (typically 2–4% of the invoice value). No debt is added to your balance sheet. No collateral beyond the invoice itself. Your credit score is not affected. Our credit decision is based on your advertiser's creditworthiness, not yours.
Sandy Seago — Key Facts
Why I Specialize in OOH
There are plenty of factoring companies in the world. Most of them work across industries — trucking, staffing, manufacturing, healthcare. They're generalists. They know the mechanics of factoring, but they don't know OOH.
OOH is different. The payment structure is different. The proof-of-posting requirements are different. The agency relationships are different. The credit profiles of the major holding company agencies — WPP, Publicis, IPG, Omnicom, Dentsu — are different from the credit profiles of a trucking company's customers. You need a factoring partner who understands all of that.
That's what I bring. Twenty years of OOH relationships, OOH-specific knowledge, and a factoring operation built specifically for this industry. When you call me, you're not talking to a generalist who will spend 30 minutes asking you to explain what a billboard is. You're talking to someone who has been in this industry as long as you have.
The Problem I'm Solving
The OOH industry has a structural cash flow problem. Operators post campaigns, incur costs, and then wait 90 to 160 days for agencies to pay. This isn't a new problem — it's been baked into how the advertising industry works for decades. Brands pay agencies on 60–90 day terms. Agencies pay vendors after they've been paid. The OOH operator is last in line.
| Agency Type | Average Payment Time | Worst Case |
|---|---|---|
| Local direct advertiser | 15–30 days | 45 days |
| Regional agency | 45–60 days | 90 days |
| National agency (mid-size) | 60–90 days | 120 days |
| Holding company agency (WPP, Publicis, etc.) | 120–160 days | 180+ days |
For an operator with $500,000 in outstanding national agency invoices at any given time, that's $500,000 of earned capital sitting in an accounts payable queue somewhere — unavailable, unproductive, and costing you opportunity every day it sits there.
MediaMark Factoring ends that arrangement. You post the campaign. You submit the invoice. You get paid in three days. The agency's payment timeline becomes irrelevant to your operations.
My Track Record
I don't ask operators to take my word for it. Here's what the numbers look like:
