A demand-side platform sold under a buyer's brand, giving them direct control over bidding, targeting, and reporting without building the stack themselves.

Multi-tenant DSP architectures sacrifice data isolation for operational simplicity — true white-label requires per-seat encryption and separate log pipelines.
Deterministic identity matching across UID2, RampID, and publisher-provided signals still outperforms probabilistic methods by 3–5x on CTV inventory.
A published, reproducible SPO methodology gives buyers confidence that the bid stream is clean — 78% of paths are now direct.
Migrating from a managed DSP seat to a white-label stack cut cost-per-install by 34% while meeting the fintech's data-isolation requirements.
Clean-room integration enables closed-loop attribution within a white-label DSP without exposing raw user-level data to either party.
