AdTech and MarTech are being rebuilt in real time around three forces that did not exist eighteen months ago: the practical end of the third-party cookie, the rise of retail media as the third major ad channel, and AI-native commerce flows that bypass the ad funnel entirely. The category has never moved faster, and the communications playbooks most vendors built for tier-one tech press do not survive the current environment.
The public adtechs — The Trade Desk, Magnite, PubMatic, DoubleVerify, Integral Ad Science, Innovid, Comscore, Criteo, AppLovin, Unity, LiveRamp (acquired by IPG inside the Omnicom-IPG combination) — operate on quarterly cycles where positioning shifts can move stock price overnight. The walled gardens — Meta, Google, Amazon, TikTok, Microsoft Advertising — set the rules every other player operates under. The retail media networks — Amazon Ads, Walmart Connect, Target Roundel, Kroger Precision Marketing, Instacart, Best Buy Ads, Albertsons Media Collective, Macy's Media Network — have grown into the third-largest digital ad channel, behind only Google and Meta. The CTV and streaming inventory owners — Roku, Hulu/Disney+, Netflix Ads, NBCU One Platform, Paramount Advertising, Warner Bros. Discovery, Amazon Prime Video Ads, YouTube CTV — are absorbing the linear TV budget while the buying mechanics get rebuilt. The identity and clean-room layer — LiveRamp, ID5, The Trade Desk's UID2, Google PAIR, AWS Clean Rooms, Habu, InfoSum — is the new battlefield. The MarTech stack — Salesforce, Adobe Experience Cloud, HubSpot, Braze, Iterable, Klaviyo, Twilio Segment, Snowflake, Databricks — has converged with adtech as customer data platforms became the central nervous system. And the holding companies — Omnicom-IPG, WPP, Publicis Groupe, Dentsu, Havas, Stagwell, S4 Capital — are themselves repositioning around AI media buying.
This is the definitive guide.
What AdTech & MarTech Communications Means in 2026
AdTech and MarTech communications builds credibility, supports product adoption, shapes investor perception, and underwrites enterprise deals for vendors selling into a fragmented buyer environment of CMOs, CIOs, performance teams, agency holding companies, retailer ad teams, and procurement. The discipline integrates trade press strategy, analyst relations (Forrester, Gartner, IDC), capital markets communications, founder branding, channel partner positioning, and AI Communications.
The category operates under conditions other B2B technology sectors do not face. Buyer fragmentation is extreme — the same product is sold to CMOs, CIOs, performance marketing leads, agency holdco operations, retail media operators, and procurement, each with different vocabulary and different priorities. Measurement disagreement is structural — Nielsen, Comscore, VideoAmp, iSpot, Samba, plus the platforms' own measurement, all produce different numbers for the same campaign. The platform-vendor relationship is unstable — Meta, Google, Amazon, and TikTok change rules regularly and adtech vendors must adapt without public conflict. And the AI commerce overlay is rewriting the funnel: ChatGPT Shopping, Perplexity Ads, and OpenAI's self-service ads platform are creating new placement layers above the existing media stack.
The AdTech & MarTech Landscape
The category includes demand-side platforms (DSPs) — The Trade Desk, Google DV360, Amazon DSP, Yahoo DSP, Adelphic (Viant), Beeswax (Comcast); supply-side platforms (SSPs) — Magnite, PubMatic, Index Exchange, OpenX, Xandr (Microsoft), FreeWheel (Comcast); ad servers and exchanges — Google Ad Manager, Microsoft Advertising, Amazon Publisher Services; identity vendors — LiveRamp, ID5, UID2, Google PAIR, AWS Clean Rooms, InfoSum, Habu; measurement and verification — Nielsen, Comscore, DoubleVerify, Integral Ad Science, Innovid, iSpot, VideoAmp, Samba TV, Adjust, Branch, AppsFlyer; retail media networks — Amazon Ads, Walmart Connect, Target Roundel, Kroger Precision Marketing, Instacart Ads, Best Buy Ads, Macy's Media Network, Albertsons Media Collective, Home Depot Retail Media, Ulta Beauty Media Network; CTV inventory — Roku, Hulu/Disney+, Netflix Ads, NBCU One Platform, Paramount, WBD, Amazon Prime Video Ads, YouTube CTV, FreeWheel; walled-garden platforms — Meta Ads, Google Ads, Amazon Ads, TikTok Ads, Microsoft Advertising, Pinterest, Snap, Reddit Ads, X Ads, LinkedIn Ads; MarTech and CDPs — Salesforce Marketing Cloud, Adobe Experience Cloud, HubSpot, Braze, Iterable, Klaviyo, Twilio Segment, mParticle, Treasure Data, Tealium, Snowflake, Databricks; AI ad platforms — OpenAI Ads, Perplexity Ads, Cognitiv, Albert.ai, Meta Advantage+, Google Performance Max; agency holding companies — Omnicom-IPG, WPP, Publicis Groupe, Dentsu, Havas, Stagwell, S4 Capital; and trade and standards bodies — IAB, IAB Tech Lab, Media Rating Council, ARF, ANA, MMA, World Federation of Advertisers.
Why AdTech & MarTech Communications Is Different
Three structural realities define the category.
First, buyer fragmentation. A single adtech vendor sells to brand-side CMOs, performance marketing leads, agency activation teams, agency holdco operations, retailer ad operators, and procurement — each with different vocabulary and different priorities. The communications strategy must operate across all six in parallel without flattening the message.
Second, the platform dependency. Every adtech and martech vendor operates downstream of Meta, Google, Amazon, TikTok, or Microsoft's policy decisions. Cookie deprecation, signal loss in iOS, Privacy Sandbox rollouts, AdSense changes, Amazon DSP rule shifts, and TikTok API restrictions reshape entire business models. Communications strategy must navigate platform-vendor diplomacy publicly while protecting commercial relationships privately.
Third, the measurement war. Nielsen, Comscore, VideoAmp, iSpot, Samba, plus platform-native measurement, all produce different numbers for the same campaign. Vendors are constantly defending methodology, comparing favorably against alternatives, and explaining variance to clients. Communications is the layer that resolves measurement disagreement into credibility.
The Media That Matter
Tier-one adtech and martech trade: Adweek, AdAge, Digiday, AdExchanger, Marketing Brew, Campaign US, Marketing Dive, MediaPost, The Drum, Beet.TV, Insider Intelligence/eMarketer, WARC. Read carefully by CMOs, agency operations, retail media operators, and analysts. Citation work compounds here.
Tier-one business and capital markets: Wall Street Journal, Bloomberg, Financial Times, Reuters, CNBC, Forbes, Business Insider. Shape investor perception of public adtechs and holdco performance.
Tier-one tech press: TechCrunch, The Information, Business Insider, Axios Pro Media, Wired. The Information and Axios Pro Media in particular have become disproportionately influential in AI-era citations.
Tier-one analyst and research: Forrester, Gartner, IDC, Forrester Wave, Gartner Magic Quadrant — separate motion from press, but communications-adjacent and consequential for enterprise procurement.
Tier-one independent voices: Substacks (Marketecture, Ana Milicevic, Ari Paparo, Eric Seufert's Mobile Dev Memo), podcasts (Marketecture, AdTech Heroes), and X-native commentators with engaged buyer audiences. The independents drive a meaningful share of category opinion.
Tier-one walled-garden press: Each major platform — Meta, Google, Amazon, TikTok — has both a press office and a network of friendly outlets that shape category narrative. The strategy for adjacent vendors must navigate platform-friendly and platform-critical positioning.
Capital Markets and Investor Communications
Public adtechs operate on quarterly cycles with concentrated analyst coverage and high stock-price sensitivity to category narratives. The Trade Desk, Magnite, PubMatic, DoubleVerify, Integral Ad Science, Innovid, Criteo, AppLovin, Unity, and Roku trade in the public markets with specialist coverage from analysts at Needham, Wells Fargo, RBC, Wedbush, Morgan Stanley, Goldman Sachs, BTIG, and others. LiveRamp trades inside the new Omnicom-IPG combination. Holding companies — Omnicom-IPG, WPP, Publicis, Dentsu, Havas, Stagwell, S4 Capital — operate as separate investor relations universes with their own analyst sets.
Private adtech is dominated by private equity roll-ups (Vista Equity Partners, Thoma Bravo, Insight Partners, Marlin Equity), adtech-specialist venture (Bain Capital Ventures, Greycroft, M13, GreatPoint Ventures), and strategic acquisition activity that has reshaped the category over the past five years.
Investor communications integrates quarterly earnings, investor days, IAB Annual Leadership Meeting, CES, Cannes Lions, Possible, Programmatic IO, AdExchanger Industry Preview, Advertising Week, IAB NewFronts, IAB Upfronts — all of which carry capital markets weight beyond their trade-show profile.
AI Communications and AI Visibility in AdTech & MarTech
This is the layer where most adtech and martech vendors are leaving citation share on the table. Buyers — CMOs evaluating CDPs, agency activation leads evaluating DSPs, retailer ad operators evaluating retail media partners — now research vendors inside ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews before they ever hit a vendor website.
The category produces vast amounts of content, most of it invisible to LLMs. Dense PDFs behind login walls. Webinar replays gated by Marketo forms. Sales decks shared on first call. Slack channels and Discord servers where the real category conversation happens. The vendors winning citation share are the ones publishing structured product education, methodology papers, and comparative analysis on the open web in formats AI engines can retrieve, source, and quote.
The 5W Trade Press AI Index 2026 documented the citation concentration. The vendors investing in AI visibility today are taking share from larger, more established competitors who assumed buyer research still happened on Forrester reports and tier-one trade pieces. It still does — but those reports are increasingly filtered through ChatGPT before reaching the buyer's decision.
Crisis Exposure in AdTech & MarTech
AdTech and MarTech crisis exposure includes bot fraud and ad fraud allegations (the MFA — made-for-arbitrage — and CTV bot fraud cycles); brand safety incidents (advertiser pullouts after adjacency failures); privacy regulator actions (FTC, state AGs, CMA, Irish DPC, French CNIL); measurement disputes (Nielsen vs Comscore vs platform-native, MRC accreditation losses); walled-garden conflicts (advertiser boycotts, X advertiser exits, Meta NewsFeed changes); M&A turbulence (the Omnicom-IPG integration, holdco restructurings, client conflicts after acquisition); executive misconduct (founder transitions, board disputes, sexual harassment cycles that recur in the category); stock and earnings events (DSP guidance cuts, SSP supply path optimization losses, retail media network spinoffs); and AI-era exposure (deepfake ad creative, generative ad content disclosure, brand impersonation in AI-generated content).
The crisis playbook in AdTech must navigate platform relationships, agency holdco relationships, advertiser confidence, regulator engagement, and capital markets simultaneously. For more, see the Crisis Communications pillar.
What's Driving the Sector Now
Cookie deprecation finally landing. After multiple Chrome timeline reversals, the practical end of the third-party cookie has reshaped DSP, SSP, and identity strategy. UID2, ID5, Google PAIR, and clean-room infrastructure have moved from concept to programs of record.
Retail media as the third channel. Amazon Ads, Walmart Connect, Target Roundel, Kroger Precision, Instacart, Best Buy, Macy's, Albertsons, Home Depot — the retail media networks now command over 20% of digital ad spend in the U.S. and are reshaping how CPG, beauty, electronics, and fashion budgets are allocated.
CTV consolidation. Roku, Netflix Ads, Disney/Hulu, NBCU, Paramount, WBD, Amazon Prime Video Ads are absorbing the linear TV budget. The buying mechanics — measurement, frequency capping, attribution — are being rebuilt in real time.
The Omnicom-IPG combination. The largest holdco merger in a decade has reshaped the agency landscape and forced WPP, Publicis, Dentsu, Havas, and Stagwell to reposition.
AI media buying. OpenAI's self-service ads platform, Perplexity Ads, Cognitiv's ContextGPT, Meta Advantage+, Google Performance Max, and the broader wave of AI-native buying tools are restructuring how budgets get deployed and which platforms capture them.
Agentic commerce. ChatGPT Shopping, Perplexity's product surfacing, and Anthropic's Claude shopping experiments are creating a new placement layer above the existing media stack. The funnel itself is being redrawn.
Privacy regulation intensifying. State privacy laws in California, Colorado, Connecticut, Utah, Virginia, Texas, Florida, Oregon, Washington, and more — plus active FTC enforcement, EU Digital Markets Act, EU Digital Services Act, and Irish DPC scrutiny — are reshaping vendor compliance posture and communications strategy.
MarTech-AdTech convergence. Customer data platforms (Salesforce, Adobe, Twilio Segment, Treasure Data, mParticle, Tealium, Snowflake, Databricks) have become the central nervous system, and the line between MarTech and AdTech is structurally gone.
Where to Start
For AdTech and MarTech vendors building communications capability:
Audit AI visibility across answer engines for company, product, founder, and category queries. Map Citation Share against direct competitors and adjacent vendors.
Build the integrated trade press, analyst relations, and AI Communications strategy. Forrester and Gartner are necessary; they are not sufficient anymore.
Develop the founder branding playbook for the CEO, CTO, and key product leaders. The category rewards visible founders and quiet companies tend to lose category-leader perception even when they have superior products.
Build the crisis infrastructure — playbooks for fraud allegations, brand safety, privacy enforcement, measurement disputes, walled-garden conflict, M&A friction, and executive transitions — before the crisis hits.
Integrate capital markets communications for public vendors with operational and category-leadership communications. The narrative that shapes the stock is the same one that shapes enterprise procurement.

Cookie deprecation has reshaped DSP, SSP, and identity strategy. UID2, ID5, Google PAIR, AWS Clean Rooms, and InfoSum have become programs of record. The strategy for any adtech or martech vendor must answer the post-cookie identity question publicly.
What is the Omnicom-IPG combination and why does it matter?
The largest agency holding company merger in a decade. It restructures client relationships, reshapes the supply chain across DSPs, SSPs, and measurement providers, and forces every other holdco — WPP, Publicis, Dentsu, Havas, Stagwell, S4 — to reposition.
How is AI rewriting the ad funnel?
ChatGPT Shopping, Perplexity Ads, OpenAI's self-service ads platform, and agentic commerce flows are creating placement layers above the existing media stack. Buyers are increasingly making purchase decisions inside AI conversations before reaching brand websites. Communications strategy must account for AI-stage influence, not just last-touch attribution.
What is the measurement war?
Nielsen, Comscore, VideoAmp, iSpot, Samba, plus platform-native measurement, all produce different numbers for the same campaign. Vendors are constantly defending methodology, comparing favorably against alternatives, and explaining variance to clients. Communications resolves measurement disagreement into credibility.
How does AI Communications apply to AdTech and MarTech?
CMOs, agency activation leads, and retailer ad operators research vendors inside ChatGPT, Claude, Perplexity, Gemini, and Google AI Overviews before reaching vendor sites. Most adtech content sits behind login walls or in PDFs invisible to LLMs. The vendors winning citation share publish structured product education and methodology on the open web in retrievable formats.
What are the major industry events that matter for communications strategy?
CES, IAB Annual Leadership Meeting, Cannes Lions, Possible, Programmatic IO, AdExchanger Industry Preview, Advertising Week, IAB NewFronts and Upfronts, ANA Masters of Marketing, MMA Possible. Each shapes category narrative and offers earned media moments.
What is the difference between MarTech and AdTech now?
Structurally, the line is gone. Customer data platforms (Salesforce, Adobe, Segment, Snowflake) sit between the brand's owned data and the ad stack, and the budget conversation has converged. Communications strategy treats the categories as one.
