Ad tech company Scope3 rebranded as Apostra on Sept. 23. In its announcement, the company outlined a platform that connects buy-side and sell-side agents to match advertisers’ briefs with media owners’ offerings. It says campaigns are already running in six countries, including France, across display, CTV, audio and out-of-home.
Advertisers provide their objectives, target audiences, budgets and guardrails. Media owners set up storefronts detailing their packages, pricing and audiences. Agents communicate through AdCP, the open protocol Scope3 helped develop, to identify relevant opportunities. Buyers set approval thresholds, while sellers retain control over pricing and packaging.
The pitch is to bring deals beyond standard ad formats into consideration: sponsorships, packages spanning multiple properties and bespoke partnerships. In practice, that means automating some of the sales work that takes place before a deal is struck and often determines what makes it into a media plan.
Surfacing opportunities buyers might otherwise miss
There are two distinct benefits here. Reducing campaign setup time improves productivity. Making opportunities cheaper to find and evaluate could change where budgets go. A media owner that rarely makes the shortlist could get a look because its agent can match its strengths to the brief, without waiting for a buyer to seek it out.
But that depends on how well the system evaluates competing proposals. Connecting two agents guarantees neither the quality of the information they exchange nor their ability to weigh a sponsorship against CTV impressions. The platform’s value will depend on the criteria used to recommend one opportunity over another.
In an interview with CMO Insider, republished by CNCB News, the founders said Apostra was working with around 40 media partners and had built adapters for Google, Meta, Amazon, Reddit and ChatGPT Ads. Co-founder and CEO Brian O’Kelley cited a $1 million U.S. campaign launched in April that subsequently expanded into other markets and channels. The advertiser was not named. Those figures offer a sense of the scale the company claims to have reached, but say little about campaign performance.
Charging for agent tasks rather than taking a cut of media spend
Apostra charges for work performed on the platform rather than taking a percentage of media spend. Creating a storefront and listing an in-house or third-party sales agent is free. Paid services are billed in “intelligence units,” which measure completed tasks.
For sellers using Apostra’s agent, the published rate is €4.50 per unit. Each completed sales response cycle uses one unit. Each eligible non-social media buy that records spend or impressions also uses one unit per billing period. Optional buy-side intelligence features are in beta, with pricing yet to be announced.
The model separates the platform’s revenue from the size of the media budget. But comparing its total cost with existing buying methods will require knowing how many billable tasks a campaign generates. A zero take rate does not mean there are no execution costs.
The pivot also reflects pressure on the original business. In the same interview, O’Kelley said weaker growth prospects in carbon measurement had prompted the company to focus on Apostra. Two rounds of layoffs reportedly reduced headcount from more than 100 to around 40.
For media owners, the real test is whether agents bring new opportunities into media plans or simply make it faster to buy from the same familiar partners. Apostra will have to prove it can change where budgets go. A slick interface won’t be enough.
