AdRoll vs. StackAdapt: Which Programmatic DSP is Best?
Topics Covered:
If you're evaluating programmatic DSPs, AdRoll and StackAdapt will almost certainly come up. Both platforms run multi-channel campaigns. Both use AI to optimize bids. Both serve agencies, brands, and B2B teams.
But at a glance, when do you choose which? AdRoll and StackAdapt were built for fundamentally different customers, with different data foundations, different integrations, and different ideas about what “full-funnel” actually means.
This guide breaks down how AdRoll and StackAdapt compare across B2C and DTC advertising, ecommerce, ABM, AI capabilities, privacy, channel coverage, and pricing.
The short version: AdRoll is a full-funnel, multi-channel, AI-powered DSP built for B2C and B2B. StackAdapt is a world-class enterprise DSP built primarily for agencies and programmatic traders. Knowing that difference changes everything. |
What Is AdRoll?
AdRoll is a demand-side platform that generates awareness, deepens interest, and drives outcomes for B2C businesses with AI-powered audience targeting, full-funnel and multi-channel advertising, and cross-channel attribution.
For nearly two decades, AdRoll has been helping brands reach ideal customers and then nurture them through to conversion. That history matters: AdRoll's proprietary AI bidding and optimization engine, BidIQ, has been trained on 4 trillion data points across 100,000+ advertisers, 1.3M+ campaigns, 194 countries, and 25+ industries — with consumer conversion data going back to 2009. That 16-year head start in B2C conversion modeling, covering ecommerce, DTC, and consumer brand categories specifically, is not something any platform can replicate quickly.
AdRoll also offers AdRoll ABM for B2B marketing teams — a purpose-built account-based marketing platform with native AI intelligence, CRM orchestration, and pipeline attribution. We cover both in this guide.

Key AdRoll capabilities
BidIQ: Automatically place the right bids, for the right price
Advertisers face growing pressure to drive stronger results with fewer resources. Every inefficient bid or missed opportunity impacts growth. BidIQ, AdRoll’s proprietary optimization engine, makes over 2.5 trillion predictions per day–including more than 1 million click predictions per second–and factors in 80+ intent signals for every impression. This real-time decision-making ensures budgets are spent where they’re most likely to perform. The result is more efficient scaling and a stronger ROI.
InIQ: Spot buyer intent as it happens
Reaching the right audiences at the right time is critical, but insight gaps often lead to missed opportunities. InIQ, AdRoll’s AI insights engine, delivers real-time intent signals, in-market trends, and audience intelligence drawn from over 2.8 billion user profiles and 25 million companies. These insights inform smarter targeting, better reach, and more effective B2B campaign outcomes from the start.
HeroIQ: Free up capacity, level up performance
The AdRoll AI Assistant is powered by HeroIQ, an intelligence and orchestration layer of specialized agents that coordinate tools into a unified, intelligent assistant. Each agent, and sub-agent, focuses on specific steps in the advertising and ABM workflow, including campaign creation, optimization, and reporting, and they work together to provide precise, context-aware support. HeroIQ agents draw on intelligence from AdRoll’s core engines and trained on platform-wide best practices and more than a decade of advertising expertise to deliver guidance that is relevant, easy to understand, and actionable.
Together, BidIQ, InIQ, and HeroIQ form an integrated AI system that combines audience intelligence, execution, and insight. They help marketers work faster, make smarter decisions, and get more value from their advertising while also keeping humans in the loop. This balance of automation and transparency reduces complexity and builds confidence in the results.
Ecommerce integrations that actually save you time
AdRoll has native integrations with Shopify, WooCommerce, BigCommerce, Wix, and PrestaShop. That means automatic pixel setup, product feed sync, four pre-built audience segments, enhanced conversion tracking, and dynamic product ads — AI-driven creative that auto-syncs your catalog and recommends the right products to the right customers.
As an added bonus: Shopify merchants also receive 10% of ad spend back in credits with qualifying plans.
Privacy-forward infrastructure
AdRoll was the first in the industry to activate audiences in Google's Protected Audience API (PAAPI) — a milestone that matters as the third-party cookie era closes. With integrations for LiveRamp Ramp ID and 33Across Lexicon ID, AdRoll is executing in the cookieless environment today.
Multi-channel reach
AdRoll offers display, native, video, mobile, CTV, DOOH, and social. AdRoll's CTV inventory includes 200M+ Experian-verified IDs and 100+ premium publishers including HBO Max, Paramount, ESPN, and Kayo. And 71% of CTV viewers are simultaneously holding their phones. That’s why AdRoll’s 4.5B cross-device identifiers matter.
Analytics and attribution
AdRoll has 17 campaign reports, 6 attribution models (including custom position-based and time-based), and a 30-day benchmark report showing how your CPM, CPC, and CTR compares across 20+ industries. Plus 12 API integrations for connecting your full marketing stack.
What Is StackAdapt?
StackAdapt is an AI-powered multi-channel programmatic advertising platform used by hundreds of agencies and brands globally. It offers display, native, video, CTV, audio, DOOH, in-game, and email channels.
StackAdapt built its reputation serving programmatic-first agencies and has expanded substantially: over 1,300 employees, $500M+ in growth capital, and operations in 19+ markets across NAMER, EMEA, APAC, and LATAM.
In October 2025, StackAdapt launched a full martech suite — GA for all users — combining email marketing, first-party data activation, and programmatic in a single platform. In November 2025, it expanded its ABM capabilities through direct integrations with Bombora, Lead Forensics, and Leadspace.
Who is StackAdapt for?
StackAdapt is the platform of choice for programmatic-first agencies managing complex media buys and for enterprise advertisers who want deep control over their inventory, targeting, and reporting. It operates across 19+ markets globally, and it carries a strong reputation for responsive account support.
Where StackAdapt is less suited: DTC and ecommerce brands that need multi-platform store integrations with auto product feed sync and pre-built DPA pipelines; brands or SMBs that need accessible pay-as-you-go pricing with no minimum spend commitment; and B2B revenue teams that need native CRM orchestration and pipeline attribution rather than a DSP with third-party intent data layered on.
AdRoll vs. StackAdapt One-to-One Comparisons
B2C and DTC Advertising
For B2C and DTC brands, the comparison comes down to five questions:
How good is the AI?
Does it connect to my ecommerce store?
Can it reach my customers wherever they are?
Is it ready for a cookieless world?
What does it actually cost to get started?
Capability | AdRoll | StackAdapt |
|---|---|---|
B2C consumer data foundation | 4 trillion data points; BidIQ trained on 1.3M+ campaigns since 2009 | Built for native/programmatic — not consumer conversion optimization at this depth |
AI intelligence layer | HeroIQ: AI agents turn natural-language instructions into campaign actions; always-on conversational guidance; hyper-personalized workflow intelligence built on 16 years of B2C conversion data | Ivy: AI assistant for natural-language campaign queries, audience recommendations, creative generation, and real-time optimization suggestions. Strong for programmatic workflows; not purpose-built for B2C conversion optimization. |
Cross-device graph | 5.4B cross-device identifiers for coherent cross-screen journeys | No published equivalent cross-device graph scale |
Ecommerce integrations | Native: Shopify, WooCommerce, BigCommerce, Wix, PrestaShop — auto pixel, product feed sync, 4 pre-built audiences, enhanced conversion tracking | Shopify App (launched Nov 2024): auto pixel install, audience creation, conversion tracking. No WooCommerce/BigCommerce/Wix/PrestaShop integrations. |
Dynamic Product Ads (DPAs) | AI-powered, auto-synced catalog, included at no extra cost — fully integrated with ecommerce platform connections | DCO available platform-wide (product feed + behavioral targeting); DCO was listed as a future enhancement for the Shopify integration specifically at launch |
Privacy-forward infrastructure | First in industry to activate audiences in Google's PAAPI; LiveRamp Ramp ID + 33Across Lexicon ID integrated — building for the cookieless future now | EU-US Data Privacy Framework certified (Jan 2026); Privacy Sandbox engagement ongoing. No published equivalent of AdRoll's PAAPI first-mover activation. |
CTV inventory | 200M+ Experian IDs; 100+ premium publishers (HBO Max, ESPN, Kayo) | Available; inventory depth varies by region |
Email strategy | Klaviyo & Mailchimp integrations: sync audiences and attribution to the email platform you already use — no migration required | Native email + programmatic orchestration suite (GA Oct 2025) with Klaviyo, Braze, HubSpot import. Powerful, but requires bringing email into StackAdapt's platform. |
Pricing | Pay-as-you-go; no fixed minimum; Shopify merchants earn 10% spend back in credits | Usage-based custom pricing; no self-serve pay-as-you-go or no-minimum tier. Reported starting point ~$5K/month per third-party reviews. |
G2 retargeting leadership | Leader: Retargeting, Mid-Market Retargeting; Best Estimated ROI | Ranked #1 DSP; not in Retargeting category leaders |
Global reach | Nearly 20 years of media partnerships across APAC, EMEA, NAMER — deep ecommerce-specific inventory relationships built over 16+ years | Strong NAMER presence; actively expanding — now operates in 19+ markets across NAMER, EMEA, APAC, and LATAM |
Pricing: who can actually use it
AdRoll offers a pay-as-you-go Ads Plan with no fixed minimum — a DTC brand at any spend level can access the full self-serve platform. The Advanced Package adds managed services, ad credits, and dedicated account management for brands that want strategic support as they scale.
StackAdapt is primarily self-serve as well, and serves brands across a wide spend range, but operates on custom usage-based pricing with no no-minimum tier. Third-party reviews suggest a starting point around $5,000/month, with managed offerings starting at upwards of $15,000/month. For the smallest DTC brands and bootstrapped ecommerce operations, AdRoll's no-minimum model provides access that StackAdapt's pricing structure does not.
Account-Based Marketing
For B2B marketing teams, the comparison is starker. AdRoll ABM was purpose-built for account-based marketing. StackAdapt is a DSP that added ABM capabilities — via third-party integrations with Bombora, Lead Forensics, and Leadspace — in November 2025.
Native intelligence vs. bolt-on partnerships
AdRoll ABM's intelligence is native. Its InIQ + BidIQ AI engine draws on 2.6B identities and 92M contacts. ICP Fit Scoring grades your target accounts A through F using a predictive model trained on your own CRM data. StackAdapt's Bombora and Leadspace integrations can surface intent data, but they remain third-party layers on top of a DSP not designed for ABM orchestration.
The difference is where orchestration ends. StackAdapt's orchestration is ad-to-email, within a marketing workflow. AdRoll ABM's orchestration extends to the CRM: it knows which accounts are ready to buy, can tell your sales rep automatically via an Account Spike alert, triggers downstream Salesforce, HubSpot, Outreach, and Salesloft workflows, and adjusts campaign pressure based on where the account sits in the revenue pipeline.
ABM Capability | AdRoll ABM | StackAdapt |
|---|---|---|
ABM intelligence | Native: InIQ + BidIQ AI, 2.6B identities, 92M contacts | Third-party bolt-on (Bombora, Lead Forensics, Leadspace — Nov 2025) |
ICP Fit Scoring | Predictive A-F grade trained on customer CRM data (200+ accounts) | No native ICP scoring engine |
Journey stage tracking | Command Center: Unknown > Aware > Engaged > Open Opportunity | No journey stage tracking |
Sales CRM orchestration | In-CRM widget (SFDC/HubSpot); Account Spike email alerts to reps; Outreach/Salesloft Workflow triggers | CRM integrations are inbound-only |
Revenue attribution | Revenue Impact Report: impressions > CRM opportunity creation > closed-won, natively at account level within CRM | Account-level reporting with Bombora/Lead Forensics integrations; multi-touch attribution models, brand lift studies, and offline footfall attribution available — but no native CRM opportunity/pipeline attribution |
Visitor identification | Native account unmasking via identity graph | Lead Forensics partnership (Nov 2025) — not native |
G2 Buyer Intent integration | Direct: triggers campaigns + sales alerts | No G2 Buyer Intent integration |
Pricing | All-inclusive: audiences, integrations, measurement, creative support | Usage-based + Bombora/Leadspace/Lead Forensics = additional third-party costs |
G2 ABM category leadership | Leader: ABM Orchestration, Marketing Account Intelligence, ABM Analytics, ABM Advertising | Ranked #1 DSP; not in ABM orchestration categories |
Pricing transparency matters in ABM
AdRoll ABM's pricing is all-inclusive, bundled with audiences, integrations, measurement, and creative support.
StackAdapt's ABM data integrations — Bombora intent audiences, Lead Forensics visitor identification, and Leadspace firmographic and technographic intelligence — are accessed directly within the platform in a streamlined self-serve workflow. However, these are third-party data providers with their own usage-based costs that scale with campaign volume; they are not platform features in the way AdRoll ABM's native capabilities are.
For teams running ABM at scale, the cumulative data costs across multiple providers can add up. AdRoll ABM's all-inclusive model makes total cost of ownership more predictable. Validate StackAdapt's current data pricing structure with their sales team, as bundling arrangements may vary.
Channel Coverage
Both platforms cover the core digital advertising channels. The gaps are specific and worth knowing.
Channel | AdRoll | StackAdapt |
|---|---|---|
Display / Banner | Yes | Yes |
Native advertising | Yes | Yes (strength) |
Video | Yes | Yes |
Connected TV (CTV) | Yes — 200M+ Experian IDs, 100+ premium publishers | Yes |
Digital Out-of-Home (DOOH) | Yes | Yes |
Mobile / In-app | Yes | Yes |
Audio | No | Yes |
In-game | No | Yes |
Dynamic Product Ads (DPAs) | Yes — AI-powered, auto-synced via ecommerce integrations, included at no extra cost | DCO available platform-wide (product feed + AI behavioral targeting); not natively connected to ecommerce platforms via integration |
Klaviyo + Mailchimp integration: audience sync + cross-channel attribution using your existing email platform | Native email within StackAdapt platform (GA Oct 2025); Klaviyo/Braze/HubSpot import; behavioral triggers + DCO across email and programmatic | |
Social (Meta / Instagram) | Yes | Yes |
StackAdapt leads on audio and in-game, and its native email + programmatic orchestration suite is a genuinely differentiated capability for teams that want to consolidate onto one platform. AdRoll's advantage is where most DTC and B2C budgets actually flow: ecommerce-native DPAs auto-synced via platform integrations, and a Klaviyo/Mailchimp connection model that lets brands keep their existing email stack without migrating to a new system.
Who Should Choose What?
You should choose AdRoll if... | AdRoll | StackAdapt |
|---|---|---|
You are a DTC or ecommerce brand | Integrations for Shopify, WooCommerce, BigCommerce, Wix, and PrestaShop with auto product feed, DPAs, 4 pre-built audiences. StackAdapt has Shopify integration (pixel + audiences + conversion tracking) but no other platforms and no auto product feed/DPA connection. | Shopify integration available; no WooCommerce, BigCommerce, Wix, or PrestaShop |
Your media budget is under $10K/month | Pay-as-you-go, no fixed minimum — full platform access from day one at any spend level | No fixed minimum; reported ~$15K/month starting point for managed, but verify directly |
You want to keep your email stack (Klaviyo/Mailchimp) and add programmatic | AdRoll integrates with Klaviyo and Mailchimp to sync audiences and attribution without pulling email into a new platform — your existing email stack stays intact | StackAdapt integrates with Klaviyo to import lists into its own email + programmatic platform. Different model: StackAdapt wants to become your email platform; AdRoll connects to the one you already use. |
Privacy and cookieless readiness matter | First to activate in Google's PAAPI — a specific, verified first-mover milestone. LiveRamp + 33Across integrations live. | EU-US DPF certified (Jan 2026); Privacy Sandbox engagement ongoing. No PAAPI first-mover activation published. |
You want full-funnel B2C retargeting | G2 Leader: Retargeting + Mid-Market Retargeting. Best Estimated ROI. | Not ranked in retargeting categories |
You are running a B2B ABM program | Purpose-built ABM orchestration: ICP scoring, journey tracking, CRM alignment, revenue attribution | DSP with third-party ABM integrations (Nov 2025) |
You are a programmatic-first agency doing complex media buys | Strong; better ecommerce and B2C capabilities | Industry-leading DSP for agency programmatic workflows |
You need audio or in-game advertising | Not available | Available |
The Bottom Line
StackAdapt is one of the best programmatic DSPs on the market. If you are a programmatic-first agency managing large, complex media buys — especially in NAMER — it is a legitimate top-tier choice.
AdRoll is not trying to be the same thing. AdRoll is a full-funnel, multi-channel, AI-powered DSP built for B2C brands and B2B ABM teams — with 16 years of consumer data, ecommerce integrations, and a pricing model that puts it within reach of more businesses.
