Why building your own adtech platform isn’t always the smartest investment, and how the right technology partner can help publishers scale faster.
In the boardroom, the argument for building your own ad management software can sound compelling. Custom engineering promises complete control, tailored workflows, and independence from external vendors.
But what happens when the real costs start adding up?
For publishers, retail media networks, and streaming platforms, deciding whether to build an in-house ad sales platform or partner with a specialized technology provider is no longer just a technical question. It’s a strategic decision that affects operational efficiency, speed to market, and long-term revenue growth.
And with AI making software development faster and more accessible than ever, the Build vs. Buy equation is changing.
At DanAds | Summit NYC 2026, industry leaders explored this exact question during the panel “Build vs. Buy: Rethinking the Backbone of Ad Sales.” The discussion highlighted how AI, modular technology, and changing business priorities are reshaping technology investment decisions.
One important takeaway? Being able to build something doesn’t necessarily mean you should.
The Build Dilemma: Control Comes at a Cost
Building a custom self-serve ad management platform offers obvious advantages: ownership of the technology, control over the development roadmap, and the ability to design workflows around specific business requirements.
But building the initial product is only the beginning.
A proprietary platform requires ongoing investment in engineering resources, maintenance, infrastructure, security, and integrations. For publishers, the total cost of ownership extends far beyond the initial development budget.
The hidden costs of building in-house include:
- Engineering and talent: Recruiting and retaining developers, product managers, architects, and QA specialists requires substantial long-term investment.
- Opportunity cost: Every month spent developing infrastructure is a month that could otherwise be spent onboarding advertisers, launching ad products, and generating revenue.
- Maintenance and technical debt: As the platform evolves, so do the demands of fixing bugs, updating infrastructure, and supporting new business requirements.
- Complex integrations: Ad servers, CRM systems, billing solutions, identity frameworks, and campaign management tools must work together seamlessly.
- Scalability and future readiness: As advertising evolves toward AI-driven workflows and agentic transactions, internally developed platforms must continuously adapt.
The challenge isn’t necessarily the cost of building a platform. It’s the ongoing cost of keeping it competitive.
When publishers dedicate significant internal resources to infrastructure development and maintenance, those resources aren’t available for strengthening advertiser relationships, improving monetization strategies, or creating new revenue opportunities.
The question becomes: Is building advertising technology really the best use of your resources?
AI Is Making Building Easier. But Is It Making It Smarter?
One of the most interesting perspectives from the DanAds | Summit panel challenged the traditional assumption that buying technology is always more cost-effective.
Oleg Kornfeld, Group President at CMI Media, shared how his organization is developing its own programmatic exchange, an ambitious initiative the agency wouldn’t have considered just five years ago.
For highly specialized businesses, such as healthcare advertising, proprietary technology can provide greater control over unique workflows, targeting requirements, and relationships with publishers. In these cases, the cost of customizing existing solutions may outweigh the investment required to build something internally.
But that doesn’t mean the same approach makes sense for every publisher.
AI-assisted development may lower the barriers to creating software, but it doesn’t eliminate the challenges of operating, maintaining, securing, and scaling that technology.
The panel also raised concerns about the rapid proliferation of internally developed AI tools. Without clear business objectives, governance, and integration strategies, organizations risk creating fragmented systems and unnecessary operational complexity.
For publishers whose core business is creating content, growing audiences, and monetizing inventory, investing in a dedicated software development operation may introduce more complexity than competitive advantage.
The smarter approach is often to build what makes your business unique, and buy the infrastructure that supports it.
Why Buying a White-Label Platform Makes Business Sense
Buying technology doesn’t have to mean sacrificing control, customization, or brand ownership.
Modern white-label adtech platforms allow publishers to deliver tailored advertising experiences while relying on specialized providers for the underlying technology. Instead of investing years into developing and maintaining proprietary infrastructure, publishers can focus on what matters most: growing advertising revenue.
Here’s where the Buy approach delivers its greatest advantages.
1. Faster Time-to-Market, Faster Revenue Opportunities
Building a complete self-serve advertising platform internally requires development, testing, integration, and continuous refinement before it can deliver value.
The adtech partner brings established infrastructure and experience from existing implementations. This can significantly reduce the time required to launch new advertising products, onboard advertisers, and automate sales workflows.
For publishers entering new markets or expanding into self-serve advertising, speed to market isn’t just an operational advantage.
It’s a revenue opportunity.
The sooner advertisers can discover inventory, create campaigns, and complete transactions, the sooner publishers can start capturing demand that might otherwise go unserved.
2. Customization Without Building Everything From Scratch
One of the biggest misconceptions about buying software is that publishers must adapt their business to the platform rather than the other way around.
White-label ad manager platforms are designed to offer flexibility while preserving the benefits of proven infrastructure.
With the right technology partner, publishers can support:
- Fully branded advertiser portals that reflect their identity and customer experience.
- Customized advertising products across display, video, CTV, audio, and other inventory types.
- Flexible buying workflows for self-serve and sales-assisted transactions.
- Integrated operations connecting campaign management, approvals, billing, and reporting.
- Configurable processes aligned with existing sales strategies and business requirements.
The result is a tailored experience without the burden of developing every technical component internally. Publishers retain control over their advertising business while leaving the complexity of software development to specialists.
3. Lower Total Cost of Ownership and Greater Operational Efficiency
The true cost of technology isn’t limited to development. An in-house platform requires ongoing investment in maintenance, updates, infrastructure, security, technical support, and integrations. As the business grows, so do these responsibilities.
Working with a specialized SaaS provider shifts much of that responsibility to a dedicated technology partner. Instead of maintaining a large internal engineering operation, publishers can leverage established infrastructure, ongoing product development, and specialized expertise.
This makes technology investments more predictable and allows internal resources to focus on revenue-generating activities rather than maintaining software.
4. Interoperability Is the New Competitive Advantage
Another important theme from this Summit panel was the need to simplify the increasingly complex advertising ecosystem.
Speakers highlighted how programmatic intermediaries can create distance between buyers and publishers, limiting transparency and restricting access to valuable audiences. As technology becomes more modular, advertisers and publishers have new opportunities to establish more direct and efficient connections.
For adtech providers, this creates a clear priority: build technology that integrates seamlessly with the broader advertising ecosystem.
An ad manager platform can help publishers connect existing ad servers, CRM systems, billing solutions, and other business-critical tools rather than replacing everything with proprietary infrastructure. The objective is to simplify operations, reduce unnecessary friction, and make it easier for advertisers to buy.
As the industry moves toward more direct and automated transactions, interoperability will be essential to staying competitive.
5. Future-Ready Infrastructure for Agentic Advertising
AI agents are beginning to reshape how advertising workflows are designed, automated, and executed. But the panel raised an important warning: rapid AI adoption without clear governance can create operational chaos.
From uncontrolled data access to fragmented internal tools and scalability challenges, building AI-driven capabilities without a defined strategy can introduce new risks instead of solving existing problems.
For publishers, preparing for agentic advertising requires more than experimenting with AI tools. It requires structured advertising products, connected systems, reliable workflows, and infrastructure capable of supporting increasingly automated transactions.
Partnering with an adtech provider can help publishers prepare for these changes without having to develop every emerging capability themselves. Rather than constantly rebuilding internal systems to keep up with new technologies, publishers can benefit from a partner focused on evolving advertising infrastructure.
The goal isn’t to build more technology. It’s to make the technology you use work harder for your business.
6. Scaling Self-Serve Advertising Without Scaling Operational Complexity
One of the strongest business cases for buying a specialized platform is the ability to expand advertising sales without proportionally increasing operational workloads.
Traditional manual sales processes can make smaller advertising budgets expensive to service. Self-serve automation creates opportunities to reach local advertisers, SMBs, and new buyer segments while reducing repetitive administrative tasks.
This allows sales teams to focus on strategic accounts and higher-value relationships, while smaller transactions can be handled through streamlined digital workflows.
For publishers, this means more than operational savings. It means making more inventory accessible, expanding the advertiser base, and creating new opportunities for revenue growth.
Build or Buy? Five Questions Every Publisher Should Ask
Before committing to an internal development project, publishers should take a step back and evaluate what they’re actually trying to achieve.
1. Is building software part of our core business?
If your competitive advantage lies in content, audiences, and advertiser relationships, does maintaining proprietary ad sales infrastructure support that advantage, or distract from it?
2. Have we calculated the full cost of ownership?
Development is only the beginning. Consider ongoing engineering, maintenance, security, integrations, infrastructure, and future upgrades.
3. How quickly do we need to generate revenue?
Would faster implementation help capture demand, launch new advertising products, or enter new markets sooner?
4. Are we prepared to keep pace with AI and agentic advertising?
Can internal teams continuously adapt the technology to new standards, automation capabilities, and buyer expectations?
5. Would partnering with specialists allow us to focus on growth?
If technology development is consuming resources that could otherwise improve monetization, customer experience, or sales efficiency, buying may offer greater strategic value.
The Smarter Path Forward: Own Your Strategy, Not Every Line of Code
The Build vs. Buy discussion at DanAds | Summit NYC 26 made one thing clear: there is no universal technology strategy. For organizations with highly specialized requirements, proprietary development may offer meaningful advantages.
But for publishers looking to modernize ad sales, simplify operations, and scale efficiently, building an entire technology stack from scratch isn’t always the best investment.
As AI accelerates software development and advertising technology becomes more modular, the most successful businesses won’t necessarily be those that build the most technology. They’ll be the ones that use technology most effectively.
