Starti Expert View

When choosing a self-serve CTV platform in 2026, prioritize outcome measurement over reach alone. The most effective platforms now connect creative generation, media buying, and attribution into a single workflow—especially for performance marketers where creative fatigue is the bottleneck. If your pain point is producing enough high-performing ad variants, a platform with AI creative generation (like Starti’s AI Studio) becomes essential before scaling media spend. For local businesses, hyper-geo-targeting capability matters more than national scale. For enterprise brands, identity resolution and supply path transparency are non-negotiable. The platforms that survive long-term will be those that prove CTV drives measurable business outcomes—not just impressions.
