How to choose a self-serve CTV advertising platform
What to evaluate in a CTV advertising platform: inventory access, measurement you can audit, minimums, and whether CTV lives in the same seat as the rest of your book.
Self-serve CTV should not mean a separate login, a separate contract, and a vanity reach report. The right platform puts connected TV in the same buying seat as display and audio: with delivery transparency and measurement you can reconcile.
Agencies lose margin and trust when CTV is a bolted-on managed package. Choose a seat you can traffic, audit, and explain.
Inventory and deals you can see
Ask how open exchange, PMP, and curated packages appear in the UI. Ask whether you can see which apps and networks actually served after the flight.
Opaque "premium CTV" bundles without delivery detail make client QBRs guesswork. Prefer deal libraries you control and reports that name supply.
Measurement you can audit
Platform-attested conversions embed the seller's incentives. Prefer first-party pixels and household-aware frequency you can reconcile.
Waveband Signal gives buyer-owned measurement beside seat delivery. Use it when clients care about outcomes, not only completion rates.
- Spend minimums and contract length in writing
- Household-aware frequency (not only device cookies)
- Delivery by app/network, not only a rollup
- First-party measurement path (pixels you own)
- CTV on the same seat as display and audio
Economics and minimums
Enterprise CTV often starts with spend floors that lock out independent agencies. Ask for published take rates or all-in fee as a percent of gross media.
Waveband publishes a media take rate that starts at 12% and ratchets toward at-cost as volume grows, plus flat SaaS by plan. No minimums to start.
How Waveband approaches CTV
CTV is a first-class channel on the Waveband DSP: VAST creatives, deal library, household frequency, and Signal for buyer-owned measurement.
Soundframe can turn audio-led creatives into VAST video for living-room reach when that fits the brief. Optional Autopilot can pace; it is never required to buy CTV.
Decision checklist
If CTV requires a second contract, a managed desk, or measurement you cannot export, keep looking. If it shares your seat, publishes fees, and lets you audit delivery, you can sell it with a straight face.
Use the CTV vendor questions article as a printable list before any commercial call.
Also check creative ops: VAST QA, deal activation time, and whether audio-led living-room flights can use a rendered video path like Soundframe without leaving the seat. Mid-size agencies lose weeks when CTV creatives live in a separate vendor queue from display.
