CTV alternatives / Publica
Publica alternatives for CTV
Publica (IAS) provides CTV ad serving and header bidding for streaming publishers. LtvAdx is a full Advanced TV exchange with SSAI, OpenRTB, and HouseholdID for operators who want serving and demand in one stack.
LtvAdx vs PublicaWhat Publica does well
Publica (acquired by IAS) is known for its unified auction model — pre-integrating the largest video SSPs into one server-side header bidding pass — and bundled ad quality verification from IAS.
Publica pioneered server-side header bidding for CTV, helping publishers increase yield by running simultaneous demand before ad selection. Post-IAS acquisition, the platform emphasizes ad quality, verification, and yield together.
LtvAdx extends beyond header bidding into SSAI manifest stitching, addressable linear, and network white-label models — targeting operators and FAST publishers who need broadcast-grade reliability with programmatic scale.
Both platforms speak OpenRTB; publishers may connect IAS verification and brand safety workflows regardless of serving vendor.
