Adtech software
Adtech software is the technology used by advertisers, agencies, publishers and ad networks to plan, buy, sell, measure and verify digital advertising. The category breaks into demand-side platforms (DSPs), supply-side platforms (SSPs), ad servers and exchanges; ad measurement and verification; mobile measurement and attribution; CTV and retail-media adtech; and a horizontal data and identity layer underneath. Cookie deprecation, walled-garden share, CTV growth and retail-media expansion define current category dynamics.
It spans DSPs and ad-buying platforms, SSPs and publisher monetisation, ad serving and exchanges, ad measurement and verification, mobile measurement and attribution (MMP), CTV and connected TV adtech, retail-media platforms, and ad creative and dynamic creative optimisation.
Revenue is dominated by percentage of media spend (take-rate) routed through the platform, transaction-based fees per impression, SaaS subscriptions for tools sold to advertisers and publishers, and recurring data and identity subscriptions sold across the ecosystem.

How adtech software companies monetize?
Adtech software companies monetize through take-rates on media spend routed through the platform, per-impression fees on verification volume and MMP per-event pricing for mobile attribution.
Take-rate on media spend
Percentage of total media spend flowing through the platform. The dominant revenue model across DSP and SSP - used by The Trade Desk, DV360, Magnite and PubMatic.
Per-impression fees
CPM-style fees on impressions served, measured or verified. DoubleVerify and Integral Ad Science use this pricing across verification volume.
SaaS subscriptions
Per-seat or fixed-fee subscriptions for advertiser and publisher tools. Used by smaller tools and SMB-facing adtech.
MMP per-event pricing
Mobile measurement partners (AppsFlyer, Adjust, Branch and Singular) price per attributed install or per attributed event. Direct relationship with the mobile advertiser.
Identity & data subscriptions
Recurring subscriptions for identity graphs, audience data and segment activation. LiveRamp anchors the category at scale.
Performance-based
Revenue tied to ad performance - installs, conversions, sales. Used by AppLovin, performance ad networks and affiliate platforms.

Adtech software market segments
Adtech software spans DSPs, SSPs, ad servers and exchanges, ad measurement and verification, CTV adtech, retail media adtech and identity and data.
DSPs (demand-side platforms)
Platforms advertisers and agencies use to buy programmatic media across exchanges. The Trade Desk dominates the independent DSP; Google DV360 anchors the walled-garden side; smaller DSPs (StackAdapt, Adform) target specific niches.
SSPs (supply-side platforms)
Publisher-facing platforms that auction inventory to DSPs. Magnite is the largest independent SSP (formed from Rubicon, Telaria and SpotX); PubMatic, Index Exchange, OpenX and Xandr (Microsoft) compete at scale.
Ad servers & exchanges
Software hosting, trafficking and delivering ads. Google Ad Manager (DoubleClick) dominates publisher ad serving globally; FreeWheel (Comcast) serves the CTV/video segment; Kevel competes as the API-first challenger.
Ad measurement & verification
Third-party verification of viewability, brand safety, fraud and ad performance. DoubleVerify and Integral Ad Science are the two scale public players; Moat (Oracle) and Adloox compete in specific lanes.
Mobile measurement & attribution (MMP)
Attribution and analytics for mobile app advertising. AppsFlyer dominates the independent MMP segment; Adjust (AppLovin), Branch and Singular compete across specific advertiser segments.
CTV & connected TV adtech
Programmatic and direct-sold advertising on streaming TV. The Trade Desk OpenPath for the demand side, Magnite for supply, Innovid for creative, plus Roku and Comcast (FreeWheel) anchoring the platform side.
Retail media adtech
Software powering Amazon Ads, Walmart Connect, Kroger Precision and Target Roundel ad networks. Criteo Commerce Media is the largest independent platform; CitrusAd (Publicis), Mirakl Ads, Topsort and Pacvue compete.
Identity & data
Data connectivity, identity graphs and audience activation. LiveRamp is the scale public name; Snowflake's Data Cloud is the underlying compute layer for adtech data sharing; Habu (LiveRamp) leads data clean rooms.

Key adtech software KPIs to track
Gross spend on platform, take rate, ARR, net revenue retention, advertisers on platform, gross margin and EBITDA margin are the metrics investors and operators track in adtech software.
| KPI | Definition |
|---|---|
| Gross spend on platform | Total advertiser spend flowing through the platform. The headline scale metric for The Trade Desk, DV360 and major SSPs. |
| Take rate | Net revenue divided by gross spend. The Trade Desk runs a steady ~20% take rate; SSPs sit at 10-20%. |
| ARR | Standard recurring revenue. Less informative for take-rate businesses where revenue is intrinsically tied to media volumes. |
| Net revenue retention | Advertiser or publisher spend on platform 12 months later. Healthy NRR sits at 115%+ for the major DSPs and SSPs. |
| Advertisers on platform | Logo count of advertisers, weighted by spend. The Trade Desk discloses concentration; the long tail is shifting toward managed services and self-serve hybrids. |
| Gross margin | Pure adtech SaaS at 70-80%; verification platforms sit at 80%+; SSPs lower (60-70%) due to publisher revenue share treatment. |
| EBITDA margin | Strong adtech businesses (Trade Desk, AppLovin) run at 25-40% EBITDA margins; smaller and SSP-tilted businesses run thinner. |

Key adtech software market trends
Cookie deprecation, the CTV adtech boom and retail media as the third wave are reshaping adtech software right now.
Cookie deprecation drama
Google announced multiple delays then partially walked back third-party cookie deprecation in mid-2024 (now opt-in rather than mandatory). Alternative identity solutions (UID2, ID5, Yahoo ConnectID and RampID) compete to replace cookies.
CTV adtech boom
Connected TV ad spend continues to grow as Netflix, Disney+, Max and Amazon Prime add ad tiers. The Trade Desk, Magnite, FreeWheel and Roku are core beneficiaries.
Retail media as the third wave
Amazon Ads at scale ($45B+ in 2024); Walmart Connect, Kroger Precision and Target Roundel growing fast; Criteo Commerce Media and CitrusAd compete to power non-Amazon retailers.
Walled gardens versus open web
Google, Meta and Amazon capture the majority of digital ad spend. The Trade Desk is the principal independent challenger on the open internet; OpenPath and the IAB Tech Lab are pushing for category-wide identity standards.
AI in creative and bidding
AppLovin AXON and Meta Advantage have shifted the auction back toward ML-driven bid and creative optimisation. Generative-AI creative tools (Smartly, Pencil) embedded in creative production.
Mobile measurement post-IDFA
Apple's App Tracking Transparency reshaped mobile attribution. AppsFlyer, Adjust, Branch and Singular have adapted via SKAN modelling and probabilistic post-IDFA attribution.
