Top Over the Top Advertising Agencies

Over-the-top (OTT) advertising delivers video ads directly to viewers on streaming platforms — Roku, Hulu, Amazon Fire TV, and connected TV devices — bypassing traditional broadcast and cable. For brands trying to reach cord-cutters and streaming audiences, OTT offers precise audience targeting, measurable impression data, and formats that can't be skipped on many platforms.

Finding an agency with genuine platform expertise and a track record of managing CPM-based buys at scale takes real vetting. Clutch evaluates every listed agency through verified client reviews and a proprietary scoring methodology.

Why Trust Clutch

At Clutch, we believe trust is the foundation of every business relationship. Our mission is to help buyers make confident, data-backed decisions informed by real client experiences.

Every review on Clutch undergoes a rigorous, human-led verification process to make sure it’s valid. Our team of specialists confirms the identity of each reviewer, ensures the project is legitimate, and only publishes reviews that meet our strict criteria.

Verification doesn’t stop at the point of publication. Our Trust & Safety team routinely audits older reviews against our guidelines. When reviews fall short of our standards, we remove them.

We evaluate service providers using a structured methodology that combines:

  • In-depth client interviews and ratings
  • Comprehensive project details
  • Market presence
  • Portfolio examples and industry recognition

This data powers tools like the Leaders Matrix, which helps you compare agencies directly. Our research team curates rankings by weighing verified reviews most heavily, so the most trusted and experienced providers rise to the top.

Using this unique combination of verified client feedback and provider-supplied insights, Clutch distills the most important details into clear, digestible summaries so you have everything you need to make confident, informed decisions quickly.

We take fraud seriously. Providers who violate our guidelines may face lower rankings, restricted visibility, or removal from the platform altogether.

Clutch’s commitment to transparency is ongoing. We’re constantly refining our systems to protect the integrity of reviews and support you in finding the right agency.

An OTT advertising agency plans, buys, and optimizes video ad campaigns that run on streaming platforms and connected TV devices. Most of these dedicated firms offer services such as:

  • Audience targeting and segmentation
  • Creative development or adaptation for streaming formats
  • Media buying across platforms like Roku, Hulu, Peacock, and YouTube TV
  • Campaign pacing and frequency management
  • Performance reporting using impression, reach, and completion rate data

OTT campaigns are typically priced on a CPM basis, with rates generally ranging from $20 – $65 CPM according to Clutch pricing data, depending on factors like inventory quality, targeting complexity, and seasonality.

Furthermore, agency management fees typically run an additional 10%–20% of media spend, while minimum monthly media commitments at many agencies start around $5,000 – $10,000.

OTT refers to any video content delivered over the internet without requiring a traditional cable subscription — it covers apps, platforms, and streaming services accessed on any device.

On the other hand, CTV specifically refers to the device type — televisions that connect to the internet. In practice, most OTT advertising budgets target CTV inventory because it delivers a TV-quality, full-screen viewing experience.

Look for proven OTT agencies that can demonstrate platform-specific experience. Ask for relevant case studies showing CPM efficiency, completion rates, and measurable business outcomes. Then, verify that they use third-party measurement tools for attribution, not just platform-reported data.

Client reviews on Clutch provide an unfiltered view of how agencies perform in communication, transparency, and ROI delivery. Take advantage of the filters we’ve prepared to help you efficiently explore firms by industry expertise, pricing, and average client ratings.

OTT agencies that can't explain their measurement methodology or rely solely on platform-reported metrics deserve scrutiny. Watch out for firms that bundle OTT into a generic digital advertising package without dedicated streaming expertise. Lastly, vague attribution claims and a lack of third-party verification tools are warning signs.
