Every CTV platform will tell you they have “premium inventory,” “advanced targeting,” and “real-time reporting.” That makes choosing one harder than it should be.
The CTV advertising platform market has grown fast. Five years ago, your options were a handful of DSPs and a couple of self-serve tools. Today, there are dozens of platforms ranging from enterprise-grade programmatic desks to self-serve tools you can set up in an afternoon. The differences between them matter more than the marketing copy suggests, especially if you’re a B2B company where most platforms weren’t built for your use case.
This guide breaks down what to actually evaluate and gives you a framework for testing before you commit.
Types of CTV Platforms
Before comparing specific tools, it helps to understand the categories. Not all CTV platforms work the same way.
Demand-Side Platforms (DSPs). Enterprise-grade buying platforms that access inventory across hundreds of publishers through programmatic auctions. DSPs offer the most inventory and targeting options, but they’re complex, often require a managed service team or agency, and have higher minimum spends (typically $25,000+ per month).
Self-Serve CTV Platforms. Purpose-built tools that let you set up, launch, and manage CTV campaigns without a media buyer or agency. They simplify the buying process, offer lower entry points ($500-$5,000/month minimums), and handle the programmatic plumbing behind the scenes. This is where most mid-market companies start.
Walled Gardens. Streaming platforms that sell their own inventory directly: Hulu Ad Manager, Netflix Ads, YouTube on TV, Amazon Ads (Freevee/Fire TV). You get guaranteed placement on that specific platform, but no cross-platform reach.
Agency Platforms. Some agencies have built proprietary CTV buying tools or have preferred platform partnerships. The advantage is hands-off management. The tradeoff: less transparency, potential markup on media costs, and you’re dependent on the agency’s expertise.
For most mid-market companies buying CTV for the first time, self-serve platforms or a DSP with managed service are the practical starting points. Walled gardens work as supplements for specific inventory needs.
What to Evaluate in a CTV Platform
When you’re comparing platforms, these are the factors that actually matter. Skip the buzzwords and ask these questions.
Inventory Access
Ask: Where will my ads actually run? Can I see the publisher list?
Not all platforms have the same inventory. Some have direct relationships with premium publishers (Hulu, Disney+, Peacock, ESPN). Others rely on programmatic exchanges where inventory quality varies. A few have both. The best test: ask for a list of publishers where your ads would run. If they can’t or won’t provide one, that’s a red flag.
Also ask whether inventory is FEP (full episode player) or includes short-form clips, FAST channels, or remnant inventory. The mix affects attention quality and completion rates.
Targeting Capabilities
Ask: Can I target by more than age, gender, and geography?
Every platform offers basic demographic and geographic targeting. The differentiators are:
- Behavioral targeting: Interest categories, purchase intent, viewing behavior
- First-party data matching: Can you upload your target account list or contact data?
- Account-based targeting: Can you target by company name, size, or industry? (Critical for B2B)
- Contextual targeting: Can you target by content genre or specific channels?
- Retargeting: Can you retarget website visitors or CTV-exposed households?
If you’re a B2B marketer, account-based targeting is non-negotiable. Most platforms built for consumer brands don’t offer these.
Minimum Spend
Ask: What’s the minimum to start, and what’s the minimum to get meaningful data?
Minimums across the market range from $500/month on budget-focused platforms to $50,000+ on enterprise DSPs with managed service. But the minimum to start isn’t the same as the minimum to learn something useful. A $500/month CTV campaign will generate so few impressions that you can’t draw any conclusions about what worked.
The minimum to start and the minimum to learn something useful are different numbers. Talk to your platform about what budget produces actionable data for your specific account universe and goals.
Measurement and Attribution
Ask: How do you measure whether my ads worked? What attribution methodology do you use?
This is where platforms diverge the most. Some offer basic impression and completion reporting. Others provide website visit attribution, conversion tracking, and incrementality measurement. For B2B, ask specifically about account-level engagement reporting (not just household impressions).
Common measurement approaches:
- Impression and completion reporting (baseline, every platform offers this)
- Website visit attribution (IP-based, matches ad-exposed households to website visitors)
- Conversion tracking (pixel-based or server-side, tracks form fills, purchases, etc.)
- Incrementality/lift testing (geo-holdout tests comparing exposed vs. unexposed markets)
- Account-level reporting (which target accounts saw ads and engaged afterward, B2B-specific)
The more of these a platform offers natively, the less you’ll need to cobble together measurement from external tools.
Self-Serve vs. Managed Service
Ask: Can I control my campaigns directly, or do I work through your team?
Self-serve means you set budgets, targeting, and creative. You control pacing and optimization. Managed service means the platform’s team runs campaigns for you based on your brief.
Self-serve is better if you want control, need to iterate quickly, or have experience buying media. Managed service is better if you’re new to CTV and want guidance, or if your team doesn’t have bandwidth to manage another platform.
Some platforms offer both. The quality of managed service varies wildly. Ask for references.
How Platform Types Compare
Different platform categories serve different needs. Here’s how the broad categories stack up across the criteria that matter.
| Enterprise DSPs | Self-Serve CTV | Walled Gardens | B2B-Specific | |
|---|---|---|---|---|
| Best for | Large budgets, agency buyers | Mid-market, hands-on teams | Guaranteed placements | Account-based campaigns |
| Targeting | Full stack (everything available) | Behavioral, demo, geo | Platform-specific audiences | ABM, firmographic, account lists |
| Minimum spend | $25K+/mo | $500-$5K/mo | Varies by platform | Flexible |
| Inventory | Broadest in market | Programmatic (varies) | Single platform only | Programmatic + direct |
| B2B features | Available via data partners | Limited on most | Limited | Purpose-built |
| Account-level reporting | Requires custom setup | Rarely available | No | Native |
| Complexity | High (steep learning curve) | Low to moderate | Low | Low to moderate |
A few things to note:
Enterprise DSPs give you the most control and the broadest inventory, but they’re built for experienced media buyers or agencies. If your team doesn’t have programmatic experience, you’ll either need to hire for it or work through a partner.
Self-serve platforms are where most companies start. The tradeoff: you get simplicity and lower minimums, but targeting sophistication and reporting depth vary significantly from one platform to the next. Some have strong performance attribution. Others are better for basic awareness campaigns.
Walled gardens guarantee you’ll run on a specific platform (Hulu, Netflix, YouTube on TV), which is great for brand adjacency. The downside: no cross-platform reach, and you’re managing separate campaigns on each.
B2B-specific platforms exist because most CTV tools were built for consumer brands. If you need to upload a target account list, target by company firmographics, or report on account-level engagement, a general-purpose platform likely won’t have those features natively. That’s why B2B-focused CTV platforms have emerged as a distinct category.
One approach gaining traction in this category is Account-Based Television (ABTV), which applies ABM principles directly to CTV. Instead of targeting broad demographics, ABTV starts with your target account list and delivers ads to decision-makers at those companies across premium streaming inventory. SpotlightIQ is purpose-built for ABTV, combining account matching, premium inventory access, and account-level engagement reporting in a managed partnership model.
The B2B Buyer’s Checklist
If you’re a B2B company evaluating CTV platforms, most comparison guides won’t help you. They’re written for consumer brands where demographic targeting and conversion tracking are the primary criteria.
For B2B, the evaluation comes down to five questions:
1. Can I upload my target account list? If you’re running account-based marketing, you need to target specific companies, not just demographics. Ask whether the platform can ingest a company list and match it to households. If the answer is “we can target by job title through third-party data segments,” that’s not the same thing.
2. Can I target by firmographics? Company size, industry, revenue range, funding stage. These are the targeting dimensions that matter for B2B. Demographic targeting (age 25-54, household income $100K+) is a rough proxy at best.
3. Can they work with your existing account lists and ABM data? CTV data is most valuable when it connects to your pipeline. Ask how they onboard your target accounts and what data formats they accept. If the CTV platform is an island, attributing results to revenue becomes manual and messy.
4. Can I see account-level engagement? “Your campaign reached 50,000 households” is a consumer metric. For B2B, you need to know: which of my target accounts were reached? Which ones visited my website after exposure? Which ones are progressing through pipeline? If the platform can’t report at the account level, it can’t prove B2B value.
5. Where will my ads actually run? B2B brand credibility matters. Ask for the publisher list. Running alongside a show on Hulu or ESPN reinforces your brand. Running on an app nobody’s heard of doesn’t. Some platforms can guarantee premium FEP placements; others can’t.
B2B CTV by Industry: What Differs
Platform evaluation shifts depending on your industry vertical. The core criteria stay the same, but the weight you put on each one changes.
Technology and SaaS companies tend to have long buying cycles and buying committees of 6 to 10 people: CTOs, VPs of Engineering, IT directors, procurement leads. That means your CTV campaign needs to reach multiple decision-makers within the same target account over months, not days. Prioritize platforms that support account-level frequency management and can report on multi-stakeholder reach within a single company. Pipeline influence matters more than immediate conversions.
Financial services and professional services add regulatory complexity. Messaging may need compliance review, and creative approval cycles are longer. Target audiences skew toward C-suite at enterprise accounts. Look for platforms that support custom audience segments and offer reporting granular enough to satisfy compliance teams. Website visit tracking after ad exposure is especially valuable here, since these buyers rarely convert directly from an ad.
Manufacturing and industrial companies often target a narrow set of named accounts with highly specific roles. The account list may be small (under 500 companies), so match rates and minimum reach thresholds become the deciding factor in platform selection.
How to Run a Platform Evaluation
Don’t commit to a 12-month contract based on a demo. Here’s a practical approach.
Week 1: Define your criteria
Decide what matters most for your use case. Write down your:
- Primary goal (brand awareness, pipeline influence, website traffic)
- Target audience (account list, firmographics, geography)
- Budget range for a test (talk to your platform about the right test budget)
- Must-have features (account-based targeting, premium inventory access, account-level reporting)
- Timeline (90 days minimum for meaningful data)
Week 2: Request demos from 3-4 platforms
Pick platforms from different categories. Don’t demo four self-serve tools that all look the same. A good evaluation set might include one enterprise DSP, one or two self-serve platforms, and (if you’re B2B) one platform with native account-based features.
During demos, ask the hard questions from the evaluation criteria above. Pay attention to what they can’t answer or redirect.
Week 3-4: Run pilot campaigns
If budget allows, run pilot budgets on 2-3 platforms simultaneously. Use the same creative, similar targeting criteria, and the same flight dates. This gives you a direct comparison of:
- Inventory quality (where did ads actually run?)
- Completion rates
- Reach and frequency
- Reporting quality and depth
- Platform usability
Week 5+: Compare results
After 30 days of pilot data, compare:
- Cost efficiency (effective CPM after all fees)
- Inventory quality (publisher mix, FEP vs. non-FEP)
- Reporting depth (can you see what you need?)
- Ease of use (could your team manage this ongoing?)
- Account-level impact (for B2B: did target accounts show activity?)
One platform will usually stand out. If none do, the problem might be your targeting or creative, not the platform.
When You Don’t Need a Platform at All
A few situations where a CTV platform isn’t the right move.
If your budget is under $5,000/month, you’ll struggle to get meaningful reach on any platform. Consider spending that budget on channels with lower entry points (LinkedIn, programmatic display) and revisiting CTV when budget grows.
If you don’t have creative ready, CTV requires video (15s or 30s spots). If you don’t have video assets and don’t have budget to produce them, the platform doesn’t matter. Some platforms offer creative services or templates, but quality varies.
If you can’t measure results, running CTV without website tracking or some form of attribution means you’re spending blind. Set up measurement first, then test CTV.
If your target audience is too small, B2B campaigns targeting fewer than 100 accounts may not generate enough matched reach for CTV to be viable. Match rates vary based on data quality and list size. If your target list is small, you may not generate enough matched reach for CTV to be viable.
The Practical Takeaway
The CTV platform you choose matters less than whether it fits your specific use case. A consumer brand running $50K/month for DTC conversions needs a different platform than a B2B company targeting 500 accounts with $15K/month.
Start with your requirements, not the platform’s marketing. Define your audience, budget, and success metrics first. Demo 3-4 options from different categories. Run pilots if budget allows. Let the data tell you which platform delivers.
The market is competitive enough that no single platform is the right answer for everyone. That’s actually good news for buyers. For more on how B2B CTV works, see our B2B CTV advertising guide. To see what real campaigns look like, check out 5 CTV advertising examples.
Frequently Asked Questions About CTV Advertising Platforms
What is a CTV advertising platform?
A CTV advertising platform is a tool that lets you buy, manage, and measure advertising on Connected TV (streaming content on smart TVs and devices). Platforms range from enterprise DSPs to self-serve tools to B2B-specific solutions. They handle the programmatic buying, targeting, and reporting so you don't need to negotiate directly with each streaming publisher.
How much does CTV advertising cost?
CTV advertising is priced on a CPM (cost per thousand impressions) basis, typically ranging from $15-55 depending on inventory quality, targeting, and platform. Premium FEP inventory (Hulu, Disney+) runs $30-55 CPM. FAST channel inventory runs $12-25 CPM. On top of media costs, some platforms charge technology fees or markups. Always ask for the all-in effective CPM.
What's the minimum budget to test CTV advertising?
Platform minimums range from $500/month on budget-focused tools to $25,000+/month on enterprise DSPs. The right test budget depends on your account universe, targeting approach, and campaign goals. Talk to your platform about what produces actionable data.
Which CTV platform is best for B2B?
Most CTV platforms were built for consumer brands. For B2B, look for account-based targeting (upload your company list), firmographic targeting (company size, industry), and account-level reporting. General-purpose platforms have limited B2B capabilities. Purpose-built B2B CTV platforms offer these features natively.
Can I run CTV ads without an agency?
Yes. Some CTV platforms let you set up and manage campaigns directly, while others take a managed or partnership approach where a dedicated team works alongside yours. An agency can help if you're new to CTV or don't have bandwidth to manage another platform, but it's not required. Most mid-market companies start with a platform that provides guidance, especially if CTV is a new channel.
How do I know if a CTV platform has quality inventory?
Ask for the publisher list. Legitimate platforms can tell you exactly which apps and channels your ads will run on. Look for recognizable names (Hulu, Peacock, ESPN, Tubi, Pluto TV). Be cautious if a platform can't or won't share where ads run, or if reporting shows impressions from apps you've never heard of. Also verify they support app-ads.txt compliance to prevent ad fraud.
