Outdoor advertising has been bought the same way for 60 years: phone calls, PDFs, and a broker taking 25 to 35 percent off the top. When we started OOH My Media, that was the problem we set out to fix. Today, OOH My Media raises its Seed Round to build the infrastructure that makes that model obsolete.
What the Funding Covers
The Seed Round proceeds go to three areas. First, expanding our placement inventory: we currently index 50,000 OOH units across 200 US markets, and we plan to reach 120,000 units by Q3 2026. Second, building out our measurement infrastructure. Right now, we deliver post-campaign reports with demographic breakdowns and third-party verified impression counts. Within 12 months, we will add mobile device graph matching that ties OOH exposure to in-store visits and website sessions. Third, growing the product and engineering teams in Miami and adding a sales team in New York.
The out-of-home advertising market in the United States generates approximately $9.2 billion annually according to OAAA data. Less than 4 percent of that spend is transacted programmatically. For comparison, digital display advertising runs 85 percent programmatic. The gap is the opportunity. Advertisers want to plan OOH campaigns the same way they plan digital campaigns - using data, booking instantly, and measuring outcomes - but the infrastructure to do that at scale has not existed until now.
Why OOH Is Different From Digital Programmatic
Building programmatic infrastructure for OOH is not the same as building a DSP for display advertising. The inventory is physical. A billboard in downtown Miami is a fixed asset. It cannot be served in real time the way a banner ad can. This means the programmatic layer operates on a hybrid model: digital OOH screens (DOOH) support true programmatic delivery with impression-based buying, while static formats operate on a plan-and-book model where we pre-negotiate rates with operators and surface them through our platform at transparent fixed prices.
Our platform handles both. DOOH campaigns can be activated in under 10 minutes through our dashboard. Static billboard bookings go live within 48 hours after creative approval. Both formats share the same planning tools, audience data layer, and post-campaign reporting interface. Advertisers do not need to know which format they are buying - the platform abstracts away those differences.
The Measurement Gap Is the Real Problem
Most OOH operators still deliver post-campaign reports that say "Your ad ran from Date A to Date B on Location X." That is not a measurement report. It is a confirmation that the ad was printed. We built our verification layer to be different: every campaign on OOH My Media includes third-party impression counts validated against Traffic Audit Bureau (TAB) methodology, demographic breakdowns by age and gender based on location-matched mobility data, and for digital screens, actual delivery logs showing when and how many times creative was served.
The next phase is connecting OOH exposure to outcomes. We have signed data partnerships that let us match device IDs exposed to a campaign against subsequent visits to a physical location. A retailer running OOH in Miami can see that exposed audiences visited their store at a 2.3x higher rate than a control group. This is the measurement capability that has kept large performance advertisers out of OOH. We are building it into the platform as a standard feature, not an expensive add-on.
Our Miami Roots and Why Geography Matters for OOH
We are based at 801 Brickell Avenue in Miami because Miami is a city where OOH advertising is genuinely competitive. The density of high-value transit corridors, the mix of English and Spanish audiences, and the concentration of national brands with South Florida regional budgets make it an ideal testing ground for what we are building. Every feature we have shipped has been validated first in Miami, which is one of the top-five US OOH markets by spend per capita.
Operating in Miami also means we are close to the Latin American advertising market. Several of our early enterprise customers are running cross-border campaigns that include both US OOH inventory and inventory in major Latin American cities. We are not announcing a Latin America expansion today, but it is a logical extension of what we are building.
What This Means for Advertisers
The immediate impact for advertisers is speed and transparency. Before OOH My Media, a brand launching a 10-market OOH campaign would spend two to three weeks negotiating with individual operators, receiving inconsistent rate cards, and managing production specs in spreadsheets. On our platform, that same campaign takes less than two hours to plan and book, with standardized contracts, automated creative specs delivery, and a single invoice. The savings are not just in time - operators on our platform post transparent rates, so advertisers are not paying the premium that comes with broker-intermediated buys.
We are also expanding our API access for agencies. Large media agencies that manage multi-market OOH buys for national clients can now integrate OOH My Media inventory directly into their planning tools. This is already live for two agency partners. Details on the API program are in our Enterprise documentation.
Looking Ahead to 2026
The 12-month roadmap has three milestones: reach 120,000 indexed placements, launch outcome measurement (store visit attribution) for all US campaigns, and ship a self-serve creative approval workflow that eliminates the current 48-hour production window for static formats. We are not trying to be everything to everyone. Our focus is on making programmatic OOH accessible to the advertisers who currently spend their budgets in digital because OOH feels too complicated and opaque. That audience is larger than the traditional OOH buyer base, and they are the customers we are building for.
