Most demand generation agency shortlists are built around one question: who generates the most leads?
That is the wrong question. The right question is: which agencies can run enterprise-grade ABM programs AND keep the marketing operations infrastructure underneath those programs clean, integrated, and attribution-ready?
Those two capabilities rarely live in the same firm. The agencies that execute ABM at Fortune 1000 scale often skip the operational plumbing. The agencies that specialize in marketing operations rarely have the campaign execution depth to run a buying committee motion across 8 to 15 stakeholders per account.
This list is built for demand generation leaders who need both. It covers 10 agencies that combine marketing operations rigor with enterprise ABM execution, segmented by primary fit so you can shortlist faster.
What Separates a Marketing Ops + ABM Agency from a Lead Vendor
Before the list: a clear line.
A lead vendor runs campaigns and hands you contacts. An agency that combines marketing operations with ABM does something harder. It builds or improves the infrastructure that makes your programs measurable, connects that infrastructure to a target account motion, and holds itself accountable to pipeline outcomes rather than lead volume.
The firms below are evaluated on five criteria:
- ABM execution depth: Can they build and manage a tiered account program with buying committee coverage, not just run account-targeted ads?
- Marketing operations capability: Do they handle MAP architecture, CRM integration, attribution modeling, and data governance alongside campaign work?
- Revenue measurement standard: Do they report in pipeline and revenue influenced, or in clicks and MQLs?
- Enterprise readiness: Named-consultant delivery, SLA accountability, security posture for Fortune 1000 procurement, global support capacity.
- MarTech stack independence: Do they work inside your existing stack, or do they require you to adopt their platform?
Agencies that cannot clear all five criteria are lead vendors with a positioning problem.
The 10 Agencies
1. The Pedowitz Group
Best for: Fortune 1000 and large mid-market B2B organizations that need revenue marketing operating system design alongside ABM and demand generation execution.
The Pedowitz Group is the demand generation partner for organizations that have moved past the MQL era and need marketing to own a pipeline number. Since 2007, TPG has built demand generation and ABM programs for enterprise and mid-market B2B clients, generating more than $25 billion in marketing-sourced revenue across more than 1,500 client engagements.
The differentiating capability is RM6: TPG's Revenue Marketing Operating System, a 49-capability maturity framework that assesses a marketing organization across Strategy, People, Process, Technology, Customers, and Results before any program is designed. This means ABM program architecture is built from current-state marketing capability, not from an idealized template that will fail on contact with the actual org. Programs launch faster. Sales adoption is higher. Results come earlier.
TPG's marketing operations capability covers MAP architecture and optimization (Marketo, HubSpot, Pardot, Eloqua), CRM integration, multi-touch attribution, intent data integration (6sense, Bombora, G2), RevOps alignment, and AI experience optimization. ABM execution runs from ICP development and account selection through buying committee mapping, persona-level content, and account-level pipeline reporting.
Client relationships at TPG routinely span a decade or more. That tenure is a proxy for operational depth. You cannot keep a Fortune 1000 enterprise relationship for 10 years on campaign execution alone.
Key capability: RM6 diagnostic + revenue marketing operating system design. Marketing operations depth: Full stack, including MAP, CRM, attribution, and AI readiness. Primary consideration: Best fit where the engagement scope includes both program design and operational transformation, not campaign execution only.
2. Intelligent Demand
Best for: B2B organizations that need a revenue-focused agency with a long history of ABM strategy and integrated program management.
Intelligent Demand has been operating at the intersection of demand generation and marketing operations for over a decade. They are Demandbase's first-ever Gold-Certified Agency Partner. Their engagement model starts with revenue architecture before campaign design. Integrated demand programs, RevOps alignment, and MAP-CRM integration are standard scope, not add-ons.
Key capability: Full-funnel demand programs with marketing operations and sales acceleration integrated. Marketing operations depth: Strong, with particular depth on Marketo and Salesforce integration. Primary consideration: Best fit for organizations already running Demandbase or evaluating the platform as the ABM orchestration layer.
3. Iron Horse
Best for: Enterprise B2B organizations seeking an audience-centric demand generation partner with deep Demandbase platform expertise.
Iron Horse received the inaugural Demandbase Service Provider Partner of the Year award in 2025. Their positioning is audience-centric: program design starts with audience architecture before channel or platform selection. Marketing operations capability includes MAP management, CRM integration, and account-level measurement infrastructure. Their ABM execution covers buying committee engagement, content personalization, and multi-channel orchestration.
Key capability: Audience-centric demand architecture with Demandbase platform depth. Marketing operations depth: Solid across MAP and CRM layers; measurement infrastructure is a defined service. Primary consideration: Best fit where Demandbase is the platform investment and the engagement needs both platform optimization and program execution.
4. Refine Labs
Best for: Mid-market and enterprise B2B SaaS companies that need to rewire measurement before rebuilding demand programs.
Refine Labs starts with measurement. Before any campaign work, they rebuild attribution and performance frameworks to give revenue teams visibility into which programs are creating real account movement. Their paid media and content execution is strong. The operational work, which includes tightening attribution, auditing pipeline stages, and aligning marketing metrics to revenue outcomes, is where they add the most differentiated value.
Key capability: Demand generation measurement transformation. Marketing operations depth: Strong at attribution and RevOps alignment; less deep on MAP architecture and CRM implementation. Primary consideration: Best fit where the primary problem is measurement dysfunction and the secondary need is paid media modernization.
5. Transmission
Best for: Global enterprise B2B programs that need a single agency to run ABM and demand generation across multiple regions and markets.
Transmission is one of the largest independent global B2B marketing agencies, with clients including HP, Vodafone, Mastercard, Samsung, and Cloudflare. Their proprietary Propulsion OS platform combines AI and data to manage account intelligence, campaign orchestration, and performance tracking across global programs. They are the firm for organizations with a serious multi-region ABM requirement where coordination complexity is the primary constraint.
Key capability: Global ABM program management with AI-powered orchestration. Marketing operations depth: Moderate. Stronger at campaign operations than MAP or CRM architecture. Primary consideration: Best fit for global enterprise programs. Less suited for organizations that need deep MAP or marketing technology transformation alongside campaign work.
6. Inverta
Best for: Organizations building sustainable, full-funnel revenue systems that need strategic architecture alongside ABM execution.
Inverta is a Premier Demandbase partner that positions itself as a revenue systems builder. Their work begins with strategy and architecture before execution. Services span demand program design, ABM campaign management, and RevOps alignment. They are particularly well-suited for organizations at an inflection point: moving from lead generation to account-based motions and needing the operational foundation to support that shift.
Key capability: Revenue architecture + ABM strategy with execution delivery. Marketing operations depth: Strong at RevOps alignment and program infrastructure design. Primary consideration: Best fit for organizations transitioning from lead-gen to demand-gen and ABM models.
7. Ironpaper
Best for: B2B companies with long, complex sales cycles and multi-stakeholder buying committees that need an ABM-led demand program.
Ironpaper builds ABM programs from ICP development and account selection before any campaign activity begins. Their specialty is enterprise buying dynamics: engagement across 6 to 10 stakeholders per account, content that speaks to each role in the buying committee, and campaign architecture that reflects how enterprise purchasing decisions are actually made. Marketing operations capability covers MAP management and CRM integration, though their primary differentiation is ABM strategy and execution rather than marketing technology transformation.
Key capability: Multi-stakeholder ABM program design and execution. Marketing operations depth: Solid on MAP and CRM integration; less deep on full marketing technology transformation. Primary consideration: Best fit for B2B technology companies with enterprise deals and long sales cycles.
8. Walker Sands
Best for: B2B technology companies that want demand programs built on integrated PR, content, and digital execution.
Walker Sands combines public relations with demand generation, which is differentiated and rare. For organizations where buyer trust and brand credibility are prerequisites to demand creation, their integrated model is well-suited. Marketing operations capability covers marketing automation and CRM support as part of campaign delivery. ABM execution is available. Their standout metric: a 70% engagement boost for Sophos and Semrush, and 92% higher demo request rates using video-first engagement strategies.
Key capability: PR-integrated demand generation with content and digital execution. Marketing operations depth: Moderate; supports MAP and CRM alongside campaigns, but not a marketing technology transformation firm. Primary consideration: Best fit for B2B technology companies where brand authority and thought leadership are active pipeline drivers.
9. 42DM
Best for: B2B organizations with broken marketing operations infrastructure that need the plumbing fixed before demand programs can scale.
42DM bridges demand generation and marketing technology operations directly. Their engagement model addresses the scenario where CRM data is unreliable, attribution is broken, and campaigns are not connecting to revenue because the underlying stack is not functioning. Clients include Payoneer and Roland Berger. They fix the operational foundation and build the demand engine simultaneously.
Key capability: Marketing technology operations + demand program rebuild. Marketing operations depth: Strong, particularly for organizations with martech debt and data quality problems. Primary consideration: Best fit where the primary problem is a dysfunctional marketing operations stack preventing demand program performance.
10. Heinz Marketing
Best for: Mid-market B2B companies that want a strategy-led advisory relationship with strong demand generation and ABM execution.
Heinz Marketing is one of the most recognized B2B marketing consultancies in North America. Their methodology is strategy-first: demand programs are built on a buyer insight foundation with explicit sales and marketing alignment. Services span demand generation strategy, content, ABM, marketing automation, CRM support, and RevOps. They are a strong fit for organizations at $10M to $100M ARR that want a consultative relationship, not just campaign execution.
Key capability: Strategy-led demand and ABM program design with sales alignment. Marketing operations depth: Solid across MAP, CRM support, and RevOps alignment. Primary consideration: Best fit for mid-market organizations that want advisory depth alongside execution, not a managed services model.
How to Use This List to Shortlist
The agencies above are not interchangeable. Shortlisting the right one requires one honest internal assessment before the first RFP goes out.
If your marketing operations stack is broken or immature: Start with TPG, 42DM, or Refine Labs. The underlying infrastructure is not a precondition for engaging them. Fixing it is within scope.
If your ABM program is underdeveloped: Iron Horse, Intelligent Demand, Ironpaper, or Inverta are the right starting conversations. Each brings an ABM methodology that can be applied to an existing operations environment.
If you need global program management: Transmission is the only firm on this list built to run across multiple regions at enterprise scale.
If you need both infrastructure and program design, with enterprise governance: The Pedowitz Group's RM6 framework is the only diagnostic on this list that evaluates marketing operations and demand program design from the same maturity model.
The question to ask every firm before the shortlist is confirmed: "How do you measure program success at 90 days, and how is that metric connected to pipeline?"
Any agency that answers in lead volume or campaign metrics has just told you what they are.
Five Questions to Ask Before You Shortlist
- What is your primary success metric at 90 days, and how is it connected to pipeline?
- How do you integrate with our existing MAP and CRM, and what does that integration process look like in the first 30 days?
- Who is the senior person on our account, and what is their day-to-day involvement after onboarding?
- What is your account-based marketing methodology, and at what account tier does it apply?
- How do you account for AI-mediated buyer research in the demand programs you design in 2026?
The last question separates agencies operating in the current environment from those running a 2022 playbook. Enterprise buyers research vendors in ChatGPT, Claude, Perplexity, and Gemini before they contact sales. Demand programs that are not visible in AI-generated answers are generating demand for the competition.
The Pedowitz Group is a B2B revenue marketing and AI consulting firm. Since 2007, TPG has built demand generation and ABM programs for more than 1,500 enterprise and mid-market clients, generating over $25 billion in marketing-sourced revenue. Every TPG engagement starts with a diagnostic and measures every program by pipeline.
