Sir Martin Funds A CTV Platform; Neutral On Neutrality By AdExchanger

Sir Funds-A-Lot
On Wednesday, TV ad decisioning platform Olyzon announced a $10 million Series A investment led by S4S Ventures, the early stage investment group co-founded by Sir Martin Sorrell and Sanja Partalo.
TV remains one of the most powerful media channels, but today’s infrastructure lacks a “coherent decisioning layer,” Sorrell tells AdExchanger.
Olyzon’s goal is to become that layer.
Its agentic technology is already available to ad buyers as a managed service. Next, the company plans to turn it into a centralized platform for planning, activation and measurement, says Co-Founder and CEO Jules Minvielle.
“Decisioning” is a big challenge in TV advertising, particularly when it comes to managing reach and fragmented inventory, he says.
Olyzon’s decisioning layer sits on existing tech stacks. From there, it qualifies content on the screen and closes measurement loops “in a way that makes every subsequent decision smarter than the last,” says Sorrell, adding that those features are “what convinced us.”
With the new funding, Olyzon plans to build out its US presence, put a bigger focus on marketing and develop deeper supply integrations and partnerships. But a portion of the funding will also go toward creating better feedback loops so that its agents are constantly retrained on the most recent campaigns, Minvielle says.
Conflicts Of Disinterest
Conflicts of interest used to be a dealbreaker in advertising. Now they’re often tolerated if the performance is good enough.
That wasn’t always the case. Once upon a time, ad agencies and vendors were held strictly to in-category client conflicts, and it was widely seen as problematic for media owners to grade their own campaign reach and value.
Those types of enforced conflict concerns are less common nowadays.
And other types of conflicts are less conflicting nowadays.
For instance, Cadent President Doug Rozen tells Digiday that the market should reset its notion of “neutrality.”
“Neutrality is table stakes,” he says. “You promise neutrality when transparency doesn’t exist.”
Rozen is nodding toward vendors like The Trade Desk and LiveRamp, which have always boasted of their “independence” and “neutrality,” an argument that held weight. (At least until recently, in LiveRamp’s case.)
Marketers and holdco leaders are increasingly willing to trust – and spend with – conflicted platforms like Google’s DV360 and Amazon Ads as long as they improve on transparency. In other words, a conflict of interest isn’t disqualifying – opacity is.
SMB GPT
OpenAI is taking its ChatGPT ads business downmarket.
After launching with large brand advertisers like Adobe, Ford and Target, which can stomach high spend minimums, the AI search engine is now expanding to smaller and local businesses.
The move suggests that OpenAI wants to become a more scalable marketing platform by expanding into SMB advertising – which makes sense, since a lot of ChatGPT queries revolve around finding nearby services.
The update also introduces more performance-oriented tools, including CPC bidding and conversion-based ads, alongside the beta program for SMBs. On top of that, advertisers can now use OpenAI’s ad pixel and Conversions API to track purchases, sign-ups and leads.
The ad platform upgrades come as OpenAI is reportedly targeting $102 billion in ad revenue by 2030 and exploring an IPO as early as September. But scaling won’t be easy. Digiday reports that time spent per ChatGPT user fell 18.3% between March and May.
Growing its ads business won’t mean much if a large enough number of consumers stop engaging with the chatbot. Advertisers are already struggling to spend their ad budgets in ChatGPT.

Sir Martin Sorrell and S4S Ventures led a $10 million Series A investment for the TV ad decisioning platform Olyzon, reflecting a view that the current media infrastructure lacks a coherent layer for making advertising decisions across television. Olyzon aims to fill this gap by developing agentic technology, initially available as a managed service, and eventually evolving into a centralized platform for planning, activation, and measurement. Sorrell articulated that the core value of the decisioning layer lies in using existing technology stacks to qualify on-screen content and establish measurement loops that allow successive decisions to become progressively smarter. With the new funding, Olyzon intends to expand its presence in the United States, deepen supply integrations and partnerships, and allocate resources toward creating robust feedback loops to continuously retrain its agents with the latest campaign data.

The discussion surrounding advertising neutrality and conflicts of interest is evolving as the industry seeks greater transparency. Experts argue that neutrality is contingent upon transparency, noting that promises of neutrality are undermined when transparency is absent. While traditional conflicts of interest were often seen as dealbreakers, there is a growing willingness among marketers to tolerate conflicts with platforms like Google’s DV360 or Amazon Ads, provided there are demonstrable improvements in transparency. The consensus suggests that opacity is the more significant barrier than the existence of a conflict of interest.

In the realm of artificial intelligence, OpenAI is expanding its advertising business, utilizing its ChatGPT platform to target smaller and medium-sized businesses beyond large brand advertisers. This expansion involves introducing performance-oriented tools, such as cost-per-click bidding and conversion-based advertising, alongside enabling advertisers to track outcomes through the ad pixel and Conversions API. However, scaling this endeavor faces challenges, as reported data indicates that consumer engagement with the chatbot is declining, suggesting that simply growing ad revenue may not be sustainable if overall user interaction wanes.

Beyond the Olyzon and OpenAI dynamics, the broader advertising technology landscape is marked by significant shifts. The market valuation and standing of major ad tech entities are under scrutiny, exemplified by the decline in The Trade Desk's market capitalization. Furthermore, the integration of AI into content creation is redefining what is considered premium content, prompting discussions about the impact of AI-generated content in the media landscape. Other developments reflect platform adjustments, including Meta's introduction of paid subscription tiers and YouTube's efforts to enhance automatic AI detection, all contributing to a complex environment where data privacy, identity solutions for CTV, and AI adoption are reshaping marketing practices.
