CTV Advertising Companies: Top Platforms to Watch in 2025

CTV Advertising Company

As Connected TV (CTV) advertising continues to rise in adoption and sophistication, selecting the right partners is critical to achieving marketing success. CTV allows brands to reach high-intent viewers with measurable, targeted video campaigns across smart TVs and streaming devices. However, not all CTV companies offer the same level of targeting, transparency, or technological innovation.

In 2025, brands require CTV vendors that can support complex audience strategies, ensure brand-safe environments, and provide full-funnel attribution. Whether you're a global agency, a DTC brand, or a local dealership, your results depend on the capabilities of your CTV platform and advertising partner.

What to Look for in a CTV Advertising Company

Before choosing a CTV advertising platform or agency, brands should evaluate partners across several key dimensions:

1. Audience Targeting Capabilities

Look for companies that offer granular segmentation: first-party data integrations, contextual and behavioural targeting, household-level reach, and cross-device syncing.

2. Transparency and Measurement

Top CTV companies provide real-time reporting dashboards, impression-level tracking, and integrations with attribution tools to connect exposure with outcomes (site visits, conversions, store visits).

3. Inventory Quality

Premium inventory is essential. Your provider should offer access to top-tier streaming publishers (e.g., Hulu, Peacock, Samsung TV+, Roku) while maintaining brand safety and low ad fraud risk.

4. Creative Flexibility

The best CTV platforms support dynamic creative, sequential storytelling, and interactive ad formats that enhance viewer engagement.

5. Customer Support and Strategy

A reliable partner acts as an extension of your team. Prioritise those who offer strategic input, creative consulting, and technical support.
