Publica (IAS): CTV ad server, ownership, pricing model and alternatives

Publica sells one thing: ad break decisioning for streaming TV. Its site describes an "open, transparent & demand agnostic" ad server with OTT header bidding, audience targeting, campaign management, server-side ad insertion, ad pod automation and analytics (Publica, accessed 9 November 2026). IAS's annual report summarises the products as "a Unified Auction, Ad Server and a Server-Side Ad Insertion ('SSAI') solution" (IAS 10-K, FY2024).

The client list leans to TV makers and free streaming services. IAS named Crunchyroll, E. W. Scripps, Fox, IGN, MLB, Samsung, Philo and XUMO as Publica publishers. Testimonials on Publica's site come from Samsung Ads, Philo and Crunchyroll (company site, Publica).

Its owner differs from its rivals' owners. FreeWheel belongs to Comcast and SpringServe to Magnite, both of which sell ad inventory or exchange access. IAS's main business is verification and optimisation for advertisers (IAS 10-K, FY2024). That does not remove every conflict, because IAS also measures the media its publisher clients sell.

Publica sits between a streaming app and its demand. When a break starts, it runs an auction among "leading video SSPs & direct demand", builds a pod and stitches the ads into the stream (Publica). The SSAI and CTV ad serving explainer shows where the stitcher sits.

Two features stand out. Elea ai is Publica's automation for keeping viewers from seeing "the same ads over and over", per a Philo testimonial (Publica). And since 5 November 2026, publishers can attach several identity signals at once through Optable, choosing which buyers receive them (PPC Land, 8 November 2026). The three named identifiers are RampID, ID5 and UID2. IAS cited an eCPM gain of about 20% at one unnamed publisher, measured against inventory with no IDs (company claim). The wider identity question is covered in identity after Privacy Sandbox.

Going private ended IAS's quarterly filings, which were the best public window into Publica. The last figures show growth: IAS's publisher revenue rose 20% to $76.5 million in 2024, "primarily due to the growth of Publica" (IAS 10-K, FY2024). In the third quarter of 2025 it rose 21%, again credited to Publica (IAS 10-Q, Q3 2025).

Publica publishes no prices, and IAS never disclosed Publica's fee structure on its own. Its filings place Publica inside publisher revenue, alongside other publisher tools. Ask for the ad serving fee per thousand impressions, any SSAI charge per stream, and whether the unified auction carries a share of programmatic spend.

Nothing directly. The court's interoperability and data remedies cover open-web display, and it rejected requests to extend data sharing to in-stream video and in-app ads (Memorandum Opinion, Dkt. 1858, p. 70). Publica keeps competing with Google Ad Manager's video tools on features and price.

Strengths

• Built only for CTV. Unified auction, podding and insertion in one product.
• Owner does not run an exchange. IAS's core business is verification and optimisation for advertisers.
• Named TV clients. Samsung, Fox, MLB and Crunchyroll appear in IAS's annual report.
• Identity options without separate integrations through Optable (PPC Land).

Limits

• Less disclosure since December 2025. IAS no longer files with the SEC.
• Stale public newsroom. The latest news items on Publica's site date from 2023.
• No pricing. Fees are negotiated.
• Measurement overlap. The parent measures the inventory its ad server clients sell.

• Publica's prices, revenue and number of clients since 2024.
• Whether Novacap plans to keep, merge or sell Publica.
• The VAST and OpenRTB versions Publica supports.
• The publisher behind the 20% eCPM figure.
