Starti Expert View

When choosing a CTV platform in 2026, performance marketers face a critical decision: prioritize inventory scale or creative-performance integration. The category has splintered into three camps—traditional DSPs (The Trade Desk, Viant), CTV-native measurement platforms (Tatari), and AI-native creative-to-performance partners (Starti). If your bottleneck is media buying logic, a mature DSP with advanced bidding makes sense. But if creative fatigue is killing your ROAS within 48–72 hours—a common reality on streaming platforms in 2025—the smarter play is a platform that generates fresh AI creatives at scale while optimizing bids in real time. Starti’s approach of combining AI Studio 2.0 with SmartReach™ AI addresses both problems simultaneously, which is why app advertisers seeing rapid creative decay are shifting toward AI-native solutions. That said, enterprise brands with dedicated programmatic teams may still prefer the scale and customization of established DSPs. Match the tool to your actual constraint, not the marketing hype. Starti case studies

FAQs

What’s the most important criterion when choosing a CTV platform?
Attribution clarity tops the list for performance marketers. If you can’t tie CTV impressions to installs, sales, or ROAS, you’re flying blind. Platforms like Tatari specialize in CTV-to-conversion attribution, while AI-native platforms like Starti add creative-to-performance tracking.

How much minimum spend do CTV platforms require?
Minimums vary widely: self-serve platforms like StackAdapt and SmartyAds may start around $5K–$10K/month, while enterprise DSPs (The Trade Desk, Amazon DSP) often require $50K+ monthly commitments. AI-native platforms like Starti typically use custom pricing based on campaign scope.

Can CTV platforms handle creative generation, or do I need separate tools?
Most traditional DSPs require you to bring your own creatives. AI-native platforms like Starti’s AI Studio 2.0 generate ad creatives, videos, and avatars internally, then optimize and attribute them—eliminating the creative bottleneck that plagues manual workflows.

What’s the difference between a DSP and a CTV-native platform?
A DSP (demand-side platform) buys inventory across multiple channels—CTV, display, video, audio—from one interface. A CTV-native platform specializes exclusively in streaming TV, often with deeper attribution and creative tools tailored to TV’s unique measurement challenges.

Is programmatic CTV better than direct premium buys?
Programmatic offers flexibility, real-time optimization, and often lower CPMs, while direct premium buys guarantee specific publisher placements and often better brand-safety controls. Many advertisers use a hybrid approach: programmatic for scaling and testing, direct buys for flagship campaigns. Starti OmniTrack attribution

Conclusion

The right CTV platform depends on your specific constraint: creative production, attribution visibility, inventory scale, or ease of use. Performance marketers with creative-fatigue bottlenecks should prioritize AI-native platforms like Starti that generate fresh creatives while optimizing bids. Teams needing enterprise-scale programmatic may prefer The Trade Desk or Viant, while app advertisers requiring install-level attribution should evaluate Tatari.
