Integral Ad Science (IAS): accreditation, ownership, CTV products, pricing and alternatives

IAS sells the same core checks as its main rival: is the impression human, could it be seen, and was the content around it acceptable. It sells them through three lines. Optimization covers pre-bid segments in buying platforms. Measurement covers post-bid reports. Publisher covers sell-side tools, including Publica. In its last public quarter, the three earned $73.7 million, $57.1 million and $23.5 million, for total revenue of $154.4 million, up 16% (Q3 2025 release, 4 November 2025).

The ownership change ends that flow of numbers. IAS agreed on 24 September 2025 to sell to Novacap in a deal it valued at about $1.9 billion (IAS, 24 September 2025). The merger closed on 23 December 2025 and the shares left Nasdaq (8-K). IAS filed to stop SEC reporting on 2 January 2026 (SEC EDGAR). Lidiane Jones, formerly chief executive of Bumble and of Slack, became CEO on 7 July 2026 (IAS, 7 July 2026).

Recent launches point at new channels. IAS said on 5 October 2026 that it is one of the first partners measuring brand safety and suitability for ChatGPT Ads (IAS, 5 October 2026). It also tracks made-for-advertising (MFA) sites, which it began measuring and avoiding in 2024 (10-K, FY2024).

The machinery is similar to other verification vendors. Pre-bid, IAS segments sit inside a demand-side platform and steer bids away from risky inventory. Post-bid, a tag or a platform feed measures each served impression, and IAS's "Firewall" can block an ad from rendering on a flagged page. Results land in the IAS Signal dashboard. The company said its platform processed more than 280 billion transactions a day at the end of 2024 (company claim, 10-K, FY2024).

What sets IAS apart is that it also serves CTV ads. It bought Publica on 10 August 2021 in a cash and stock deal valued at $220 million (IAS release, 10 August 2021). Publica runs a unified auction, an ad server and server-side ad insertion (SSAI) for streaming publishers, and IAS said it served more than 10 billion CTV ads a month (company claim, 10-K, FY2024). Viant connected its Direct Access buying product to Publica supply on 8 July 2026 (IAS, 8 July 2026). The Publica profile covers the ad server in detail.

That position gives IAS data a pure buy-side verifier lacks. IAS Total TV, launched on 27 April 2026, reports genre, rating, language and show-level data in aggregate from Disney, NBCUniversal, Paramount and Prime Video, plus opted-in Publica publishers (IAS, 27 April 2026). A buyer can see which kinds of programmes carried a CTV campaign, not just which apps.

The Media Rating Council (MRC) voted on 9 July 2026 to continue accreditation of IAS's Campaign Monitor, Firewall and Viewability Systems platform and its CTV measurement platform. It also granted first-time accreditation for pre-bid segments. A separate letter of 7 November 2025 covers reporting through Amazon DSP. The table combines both letters with the MRC's public list, read on 9 November 2026 (MRC letter, 9 July 2026; MRC accredited digital services).

Three gaps stand out for connected TV (CTV). Fraud and viewability are accredited on TV screens, but only for certified apps. Property-level brand checks stop at desktop and mobile web. And IAS's audit of content-level brand safety on YouTube, covering English and Spanish video on all four screens, had been in process since April 2023 without a decision (MRC services under review).

A rule change affects how vendors may describe those checks. The MRC said on 18 October 2025 that text-based property-level services may not be sold as "brand safety" without content-level analysis. Vendors had until 18 April 2026 to comply (PPC Land, 24 October 2025).

On fraud, the TAG link runs through the MRC. An addendum to the July 2026 letter says the accredited SIVT functions meet two Trustworthy Accountability Group (TAG) Certified Against Fraud requirements: filtering known fraudulent domains and data-center IP addresses (MRC letter, TAG addendum).

IAS publishes no prices. Its last annual report says customers mainly pay "a fee based on the total volume of ads measured", charged as a CPM. Some contracts use "minimum commitments, overages based on tiered pricing or flat fees" (10-K, FY2024). The same filing shows that price per impression can fall while volume grows: measurement revenue rose 13% in 2024 as impressions grew 23% and average CPMs fell 7%.

Pre-bid products carry a second cost layer. IAS pays revenue share to DSP partners on optimization revenue, so the price a buyer sees in a DSP may bundle both (10-K, FY2024). Ask which line items the DSP collects and which IAS bills directly.

Strengths

• Buy side and sell side under one roof. Publica gives IAS a CTV ad server and programme-level data that pure verifiers lack (IAS, 27 April 2026).
• Accredited SSAI metrics. IAS and Pixalate are the two vendors on the MRC list with accredited SSAI video metrics, which matter where ads are stitched into streams (MRC).
• Accredited walled-garden reporting. Meta, YouTube and Amazon DSP feeds sit in the MRC scope, each with stated limits.

Limits

• Narrower accredited scope than DoubleVerify. No accredited property-level checks in apps or CTV, and pre-bid IVT is limited to IP and user-agent methods (MRC letter).
• Less public data since going private. No filings after Q3 2025, so buyers lose audited revenue, retention and mix figures.
• A possible conflict to manage. Owning an ad server and verifying ads served by others is a structural tension buyers may want addressed in contracts.
• A long-pending YouTube audit. The content-level audit has run since April 2023.

• Revenue, customer counts or headcount after September 2025, which IAS no longer files (SEC EDGAR).
• IAS's attention product status at the MRC; no attention accreditation or audit for IAS was listed on 9 November 2026.
• Current CPM rates or minimum commitments.
• IAS's entry in TAG's public registry, which our tools could not load.
