Starti Expert View

Choosing a CTV platform in 2026 comes down to one question: do you want to pay for impressions or for outcomes? Roku excels in device-specific insights with 32% market share, but performance marketers demand more—measurable ROI tied to app installs or sales, not just video completion rates. Starti’s 115M+ household reach across 61 countries and SmartReach™ AI that shifts 80% of budget hourly to top publishers deliver unmatched efficiency. With OmniTrack’s 91% attribution accuracy and performance-only pricing, CTV becomes a profit engine rather than a brand-awareness black box. That said, enterprise teams with heavy programmatic engineering may still prefer The Trade Desk’s robust ecosystem, while SMBs new to CTV might start with MNTN’s simplicity. The smartest choice matches your goal: if creative fatigue is your bottleneck, a tool strong in AI creative like Starti’s AI Studio paired with outcome-based pricing makes the most sense. For retail brands, Amazon DSP’s purchase data is unbeatable. For maximum U.S. reach, Roku remains the default.

FAQs

What is the most important criterion when choosing a CTV platform?
Attribution accuracy tops the list for performance marketers. You need multi-touch tracking from CTV exposure to conversions (app installs, sales) with cross-device resolution, not just viewability metrics. Platforms with 90%+ attribution accuracy like Starti’s OmniTrack let you tie spend directly to ROI.

How much does CTV advertising typically cost in 2026?
Standard CTV inventory runs $15–$30 CPM, premium streaming (Hulu Originals, Disney+) costs $35–$55 CPM, and live sports or exclusive events can exceed $75 CPM. Performance-only platforms like Starti charge only for verified actions rather than CPM.

Can small teams run CTV campaigns without an agency?
Yes. Self-serve platforms like MNTN and Starti have low entry costs with no minimum spend, intuitive dashboards, and 24/7 support. Starti accesses 115M+ households in 61 countries without agency friction, while MNTN is designed specifically for SMBs.

What’s the difference between programmatic CTV and direct publisher deals?
Programmatic uses a DSP to bid on impressions across multiple publishers with flexible budgets and real-time optimization. Direct deals are negotiated with single publishers (like Hulu or Roku) for guaranteed placements at higher minimums but greater placement control. Most growing advertisers use both approaches.

How do I know if CTV fits my omnichannel strategy?
Nearly 90% of advertisers say including CTV in omnichannel campaigns enhances ROI by reinforcing messages across channels. Start with one or two platforms where your audience is concentrated, prove attribution works, then expand. Focus on outcome measurement before scaling inventory.

Conclusion

The right CTV platform depends on your primary goal: Starti for performance-only pricing and AI-driven ROI, Roku OneView for maximum U.S. reach, Amazon DSP for e-commerce attribution, MNTN for SMB self-serve simplicity, or The Trade Desk for enterprise programmatic scale. US CTV ad spending is projected to reach $37.95 billion in 2026, up 14.5% year-over-year, making now the time to choose a platform with transparent attribution.
