A8 Media today released Signal, a proprietary planning and campaign insights platform for digital out-of-home advertising, built to narrow buys from city-wide coverage down to individual screens. The London announcement describes an internal tool used by the agency's own planners rather than a product sold to advertisers, and it arrives in a British outdoor market that has now posted two consecutive quarters of double-digit revenue growth.
In Short
A small British out-of-home agency has built its own software for deciding which advertising screens to buy. Instead of booking every screen in a city, the tool maps where a brand's customers actually go and picks the screens near those places. It matters because outdoor screen buying has been getting more complicated as more screen owners and formats arrive, and the planning data needed to do it well sits scattered across separate systems.
What the platform is meant to do
A8 Media described Signal, in a statement issued from London on 9 September 2026, as its proprietary digital out-of-home planning intelligence and campaign insights platform. The framing throughout the announcement is internal. Signal, according to the company, will help its own team plan campaigns, understand performance and deliver results for clients. No pricing, availability date, client-facing interface or third-party licensing arrangement appears anywhere in the material.
The central function is location selection. Signal identifies the locations, and then the screens, most relevant to a given brand or campaign, according to A8 Media. The company frames that granularity as a budget-control mechanism: spend concentrates on the locations judged to matter rather than spreading across an entire market. A second consequence follows from the same mechanic. Smaller regional advertisers, for whom a national or city-wide buy has historically been unaffordable, can in principle run a viable campaign on a short list of carefully chosen screens.
That is the stated commercial argument, and it is worth reading precisely. The claim is not that screen-level selection produces better outcomes than broad coverage. The claim is that it makes a smaller buy coherent. Whether a regional advertiser buying twelve screens outperforms the same advertiser buying nothing at all is a question the announcement does not attempt to answer with data.
The alternative it is positioned against
A8 Media contrasts the approach with buying across an entire city. Signal, the company says, can isolate screens located around key customer touchpoints, and it names three examples: community hubs, commuter stations and retail stockists. The retail stockist case is the most specific of the three, since it implies a known distribution list rather than an inferred behavioural pattern. A brand that knows which shops carry its products can define a screen set from that list directly.
The data going in
Signal brings together data from multiple sources to build A8's picture of audiences and key locations, according to the company. On top of that base, further datasets can be uploaded per brand or per campaign. The announcement names four categories: first party customer data, search data, performance data from previous campaigns, and mobile movement data.
Each of those four carries different properties, and the announcement does not distinguish between them. First party customer data is the advertiser's own record of who bought what and where, typically the most reliable input and the most narrowly scoped. Search data indicates category demand by geography without identifying individuals. Historical campaign performance is retrospective and inherits whatever measurement flaws produced it. Mobile movement data is the category that has drawn the most regulatory attention, and it is also the one that underpins most commercially available footfall attribution in the channel.
The stated logic connecting the four is simple: identifying where customers are located indicates where interest in a brand, product or category is likely to be greater. That is a proximity assumption. It holds better for some categories than others, and the announcement offers no accuracy figures, no measurement partner, and no named data supplier for any of the four inputs.
The output is visual. Signal gives the planning team a view of the locations relevant to each campaign and indicates where investment is best concentrated, according to A8 Media. Optional artificial intelligence tools sit alongside that view and provide support where useful, in the company's phrasing. The description is unusually restrained by the standards of 2026 product announcements. AI is presented as an assistive layer rather than as the decision-making engine, and no model, vendor or automated action is named.
Measurement after the campaign runs
The second half of the platform addresses evaluation rather than planning. Signal combines campaign performance, audience and measurement data to establish who a campaign reached and what impact it had against each brand's objectives, according to the company. Those insights are then intended to optimise live activity, identify further opportunities, inform subsequent planning and support cross-channel re-messaging.
The re-messaging element is the most technically interesting claim in the announcement and the least specified. Reinforcing an outdoor exposure through another channel requires either a device-level link between the screen exposure and the subsequent digital impression, or a geographic proxy standing in for that link. Outdoor advertising is a broadcast medium, so exposure attribution generally depends on mobile location panels and modelled audience estimates rather than on device-level delivery records. The announcement does not say which method Signal uses, nor which demand-side systems receive the resulting audience.
Two founding dates in one document
The press release contains an internal inconsistency about when A8 Media was established. The body text states that the company was set up in 2025. The boilerplate at the foot of the same document states that A8 Media was founded in 2024 by Chris Childs and Amin Rahman. Both statements appear in the material distributed on 9 September 2026, and the announcement offers no reconciliation. The discrepancy sits in the source material rather than in its reporting.
The Hawk lineage
The founders' backgrounds are the strongest signal in the announcement about how Signal is likely to have been designed. Managing director and co-founder Chris Childs led the UK launch of the omnichannel demand-side platform Hawk and grew that business until its acquisition by Azerion, according to A8 Media. Co-founder and operations director Amin Rahman was Hawk's UK head of advertising operations.
Hawk was founded in 2013 by Hakim Metmer and Renaud Biet, establishing a research and development centre in Montpellier the following year with 45 engineers, before launching a self-service platform in 2018. Under Azerion the platform has continued to accumulate supply and data. Azerion integrated Global Data Resources into Hawk on 29 January 2026, adding cookie-free geo-demographic targeting across 13 European markets, with segments addressing geographic clusters rather than individuals. Four months later, on 28 May 2026, the company routed Spotify Ad Exchange inventory directly into the platform. In January 2025 Hawk had already extended its European connected television reach through a smartclip integration.
The relevance is architectural. Geo-demographic segmentation, cookie-free location targeting and a buy-side data marketplace are the components a team drawn from that environment would be expected to reach for when building an outdoor planning system. Signal's description, with its uploaded datasets and its map-based output, is consistent with that heritage.
Childs framed the launch in modest terms. "We're not trying to reinvent out-of-home, but we are investing in the tools," he said, describing Signal as an instrument that lets the team be forensic in how it plans, optimises and evaluates campaigns. He added that the platform consolidates the information the team already uses daily to make better-informed decisions about audiences and locations, and that it gives clients greater confidence in where their outdoor investment goes.
Two growth figures, both British
The announcement supports its market case with two statistics, and neither is labelled by geography in the text. Both are United Kingdom figures.
The first is a 12.7% increase in out-of-home revenues in the second quarter of 2026. That is the Outsmart figure, collated by PwC, covering the British market: revenue of £402.6 million against £357.3 million a year earlier, the highest second quarter on record and the second highest quarter of any kind after the fourth quarter of 2025. Within that total, digital revenue grew 14.6% and classic formats grew 8.8%, with digital taking a 68% share. Across the first half of 2026, British out-of-home revenue reached £743.9 million, up 13.7%.
The second statistic is the forecast that digital will account for 76% of out-of-home advertising spend by 2031. That comes from IAB UK's Compass report on the channel, published on 28 July 2026, and it too describes the British market specifically. The same report recorded digital investment of £964 million in 2025, or 67% of British out-of-home spend, up from 32% in 2015.
Reading either figure as a global indicator would overstate the position elsewhere. United States out-of-home revenue rose 10.7% in the second quarter of 2026 to $3.16 billion, the first quarter above $3 billion, with digital at 38.4% of the total against Britain's 68%. Guideline's March 2026 forecast put United States digital growth for the year at 14.5% while traditional formats grow 1.5%. Britain is further into the transition than the largest advertising market in the world, which is part of why a British agency would build a screen-level planning tool now rather than in three years.
The fragmentation the tool is answering
A8 Media developed Signal in response to changes in the outdoor market, according to the company. Traditional billboards have been supplemented by digital screens across a range of environments; the volume of audience data, location intelligence and campaign reporting available to planners has increased substantially; and more media owners and screen formats have produced fragmentation, with detailed insight spread across multiple platforms.
That diagnosis matches conditions documented across the wider media technology market. A Mediaocean survey published in January 2026 found platform fragmentation was the largest concern for 56% of marketers, and that only 10% described their advertising technology stacks as fully unified. The response pattern has been consistent through 2026: consolidate the inputs into one interface and reduce the manual reconciliation between them. Basis released an agentic planning tool converting briefs into omnichannel plans in April 2026, and Guideline connected its media plan management system to Mediaocean's Prisma through new interfaces in June 2026.
Outdoor supply has been consolidating on the same timeline. VIOOH brought roughly a quarter of the United States digital outdoor market into programmatic reach through an OUTFRONT partnership announced on 9 March 2026, covering more than 7,600 screens and 18 billion monthly impressions. Broadsign opened advance guaranteed booking across North America with StackAdapt in November 2025. Each of those additions widens the addressable inventory a planner has to sort through, which is the condition that makes a selection tool useful in the first place.
Location measurement has been consolidating too. The Trade Desk connected Adsquare into its Audience Unlimited marketplace in June 2026, drawing on location signals sourced through mobile software development kits rather than the bid stream. Stagwell renamed its People Platform business Numetrix on 1 September 2026, positioning it explicitly as a consumer behavioural data and location intelligence provider serving outdoor media owners, retail media networks and brands.
What the announcement leaves open
Several material questions go unaddressed. The release names no screen count, no media owner integrations, no market coverage beyond a general reference to the United Kingdom and international markets, and no client. It does not say whether Signal executes buys or only informs them, whether it connects to any supply-side platform or demand-side platform, or how the mobile movement data reaching it was collected and consented. No accuracy benchmark, case study or performance figure accompanies the launch.
The absence of a client-facing product is the defining structural fact. Signal is described as a tool for A8's planners. Whatever value it creates reaches advertisers through the agency's recommendations rather than through a login, which places the burden of verification on the agency relationship rather than on an auditable interface.
Why this matters for the marketing community
For buyers, the announcement is a data point about where competitive differentiation in outdoor advertising is migrating. Access to inventory is no longer scarce; supply-side platforms have spent two years opening roadside, transit, retail, residential and streaming screen inventory to automated buying. What remains scarce is the judgement about which of those screens to buy, and independent agencies are now building that judgement into software they own rather than renting it from the platforms selling the media.
For advertisers weighing outdoor budgets, the proximity assumption embedded in tools of this kind deserves scrutiny. Selecting screens near where customers are known to be is intuitively sound and empirically unproven at the level of a single campaign. The measurement layer that would settle the question, footfall and cross-channel attribution built on mobile location panels, is the same layer under active regulatory pressure in several jurisdictions and still lacking a common auditing standard.
For regional advertisers specifically, the accessibility claim is the one to watch. If screen-level planning genuinely lowers the entry cost of the channel, it expands the pool of outdoor buyers well beyond the national brands that have historically dominated it. That would show up in the revenue data before it shows up in any product announcement.

Summary
Who: A8 Media, a specialist out-of-home advertising and audience intelligence business based in London, founded by managing director Chris Childs and operations director Amin Rahman. Childs led the United Kingdom launch of the omnichannel demand-side platform Hawk before its acquisition by Azerion; Rahman was Hawk's United Kingdom head of advertising operations.
What: The release of Signal, a proprietary digital out-of-home planning intelligence and campaign insights platform. It selects individual screens rather than city-wide inventory by combining audience and location data with optional uploaded datasets covering first party customer records, search demand, prior campaign performance and mobile movement, then reports campaign reach and impact for optimisation and cross-channel follow-up. Optional artificial intelligence tools sit alongside the planning view. The platform is described as an internal tool for A8's own planning team.
When: 9 September 2026. The announcement follows Outsmart and PwC figures showing British out-of-home revenue of £402.6 million in the second quarter of 2026, up 12.7%, and an IAB UK forecast published on 28 July 2026 projecting digital at 76% of British out-of-home spend by 2031.
Where: Issued from London, covering the United Kingdom and international markets. The two market statistics cited in the announcement both describe the British market specifically, a qualification the release does not make.
Why: More media owners and screen formats have fragmented outdoor inventory, and the audience data, location intelligence and campaign reporting needed to plan against it sits across separate systems. Signal consolidates those inputs into a single view so budgets concentrate on selected locations, an approach the company says also lowers the practical entry cost of the channel for regional advertisers.
