What Is Marketing Execution in a PE Context?

Most PE portfolio companies have a marketing problem, but it is rarely the problem the board thinks it is.

The surface-level symptom is familiar: pipeline is light, brand awareness is low, the website looks like it was built three years ago (because it was), and the marketing team is either one overworked generalist or a revolving door of VPs who keep leaving before their programs mature. The operating partner's instinct is to throw money at the problem — hire an agency, increase paid spend, launch a content program, buy a marketing automation platform. Within six months, marketing spend has doubled and pipeline contribution has not moved.

The underlying issue is that most PE portcos do not have a marketing execution problem. They have a marketing operating model problem. There is no systematic connection between strategy and execution, between spend and attribution, between the campaigns running in HubSpot or Marketo and the pipeline showing up in Salesforce. The marketing function was built for a founder-led company doing $5M in revenue, and it has been duct-taped forward through a $30M growth phase without anyone stopping to architect the system that connects marketing activity to revenue outcomes.

Marketing execution in a PE context means building that system — not just running campaigns, but constructing the entire operating model that makes marketing measurable, scalable, and accountable to the growth targets the value creation plan requires. This includes demand generation strategy and execution, marketing operations and technology infrastructure, content and messaging architecture, attribution and analytics frameworks, and the organizational design that ensures the marketing team can actually deliver against the plan.

The category spans a wide spectrum of providers. On one end are specialized agencies that excel at specific channels — paid media, inbound content, SEO — and can deliver tactical execution at high quality. On the other end are firms that operate more like embedded marketing departments, building the full stack from strategy through infrastructure through execution. In between are consulting firms that design marketing operating models but rely on the portco team or third-party agencies for implementation.

For PE operating teams, the critical evaluation question is not "who runs the best Facebook ads" — it is "who can build a marketing engine that will survive the next VP of Marketing hire, scale with the business through the hold period, and produce attribution data clean enough to support an exit narrative." That question eliminates most of the provider landscape and narrows the field to firms that think in systems rather than campaigns.

The typical engagement ranges from $10,000–$25,000 per month for channel-specific agency work to $30,000–$75,000+ per month for full-stack marketing execution partnerships. Sprint-based engagements for marketing operating model builds can range from $50,000 to $200,000+ depending on scope. Timelines vary from 90-day sprints to multi-year embedded partnerships aligned with the PE hold period.

Two failure modes dominate this category. The first is hiring a marketing agency when what you need is a marketing operating model — paying for campaign execution before the infrastructure exists to measure, optimize, and attribute that execution to revenue. Money flows, dashboards show impressions and clicks, and nobody can connect any of it to closed-won deals. The second failure mode is over-investing in marketing strategy without committing to execution — a consulting firm delivers a beautiful go-to-market plan, the portco lacks the team and systems to implement it, and the plan joins a growing collection of PowerPoint artifacts that nobody references after the first board meeting.

What to Look For in a Vendor

Do they build systems or run campaigns? This is the first filter. A firm that defines marketing execution as "we will manage your Google Ads and write blog posts" is an agency. A firm that defines it as "we will build the marketing operating model that connects strategy to pipeline to revenue attribution" is a marketing execution partner. PE portcos typically need the latter, even if they also need help with the former. Ask what the engagement looks like after month six — if the answer is "more of the same campaigns," the firm is probably not building toward independence.

Can they connect marketing activity to revenue outcomes? Attribution is where marketing execution for PE portcos succeeds or fails. The vendor should be able to articulate exactly how they will track marketing-sourced pipeline, marketing-influenced pipeline, and the cost to acquire opportunities through each channel. If the firm talks about impressions, engagement rates, and MQLs without connecting those metrics to pipeline dollars and closed-won revenue, their measurement framework is not built for PE reporting requirements.

Do they understand PE timelines and governance? A marketing partner serving PE portcos needs to understand that the hold period is finite, that quarterly board reporting requires specific metrics, that the value creation plan has defined targets, and that marketing is being evaluated as an investment with expected returns — not as a brand-building exercise with soft metrics. Ask how they structure reporting for PE operating partners and board presentations. If the answer requires translation from marketing jargon, the firm has not served PE clients.

What is their technology stack posture? The MarTech landscape is a minefield for portcos. A vendor that is platform-agnostic — capable of working across HubSpot, Salesforce, Marketo, Pardot, and hybrid environments — provides more value than one locked to a single platform. But platform expertise also matters: a firm that is an elite partner of HubSpot or Salesforce will know the platform's capabilities and limitations at a depth that a generalist cannot match. The right answer depends on what the portco is running today and what the value creation plan requires.

Do they transfer capability or create dependency? The best marketing execution partners for PE portcos build toward handoff. They establish processes, train internal teams, document systems, and create playbooks that allow the portco to operate independently as the marketing team matures. Firms that create structural dependency — where the portco cannot function without the agency — are optimizing for their own retention, not the portco's value creation.

What is their PE portfolio experience? Pattern recognition matters. A firm that has served multiple PE portcos across different sectors will recognize common failure patterns — the CRM that has never been cleaned, the marketing automation platform that was bought but never configured, the attribution gap between marketing and sales — and will move faster because they have solved these problems before. Ask for PE-specific case studies. If they do not have any, you are their pilot program.

Vendor Notes

Winning by Design — ⬤ Marketing Strategy

Winning by Design has built one of the most recognizable methodologies in B2B revenue architecture. Founded by Jacco van der Kooij, the firm approaches marketing not as a standalone function but as one component of a unified revenue engine — a perspective rooted in their "Revenue Architecture" framework that maps the entire customer journey from first touch through expansion and renewal. Their methodology is scientific in orientation: data-driven, process-oriented, and designed to produce repeatable, measurable outcomes rather than creative campaigns.

The firm's strength is in designing the system — the operating model that connects marketing to sales to customer success in a way that produces predictable revenue. Their training and consulting programs are built around blueprints that teams can implement and iterate on. Published content includes detailed frameworks for metrics, process design, and team structure that are freely available and widely referenced in the B2B revenue operations community.

For PE portcos, Winning by Design is strongest when the marketing problem is fundamentally a design problem — when the issue is not campaign quality but the absence of a systematic connection between marketing activity and revenue outcomes. The limitation is execution density: Winning by Design is primarily a training and consulting firm, not an execution agency. They will design the machine, but the portco team (or a separate agency) needs to run it. For portcos with capable but unstructured marketing teams, this is ideal. For portcos that need someone to do the work, not just architect it, additional execution resources will be required.

New Breed — ⬤ Demand Gen Execution

New Breed is a HubSpot Elite Partner that has built its practice around inbound marketing and revenue operations execution. The firm positions itself as a full-funnel growth partner, covering demand generation, website development, marketing automation, sales enablement, and revenue operations — all within the HubSpot ecosystem. Their depth on the HubSpot platform is a genuine differentiator: as an Elite Partner (the highest tier in HubSpot's partner program), New Breed has platform expertise that generalist agencies cannot match.

The firm's published case studies emphasize measurable outcomes — pipeline generated, conversion rates improved, revenue attributed to marketing programs. Their methodology is structured around what they call "revenue performance management," which connects marketing execution to pipeline and revenue metrics rather than vanity metrics. New Breed also offers HubSpot implementation and migration services, which is relevant for PE portcos that need to consolidate disparate marketing tools onto a single platform.

The PE-specific limitation is platform dependency. New Breed is a HubSpot firm — if the portco runs Salesforce Marketing Cloud, Marketo, or Pardot, New Breed is not the right fit unless a platform migration is already in the plan. For portcos that are on HubSpot or moving to HubSpot, New Breed provides a level of integrated execution and platform expertise that is difficult to replicate with a platform-agnostic agency.

SmartBug Media — ⬤ Content & Messaging / ⬤ Demand Gen Execution

SmartBug Media is one of the largest and most recognized HubSpot partners in North America, with a practice built around what they call "Intelligent Inbound" — a methodology that extends traditional inbound marketing with paid media, PR, web development, and marketing automation. The firm has scaled significantly, with a team of 150+ employees and a client base that spans B2B technology, healthcare, and professional services.

SmartBug's published case studies are among the most detailed in this landscape, with specific metrics around traffic growth, lead generation, conversion optimization, and revenue attribution. Their content marketing capabilities are particularly deep — the firm produces high volumes of blog content, pillar pages, case studies, and sales enablement materials, supported by SEO strategy and distribution through paid channels. They also offer HubSpot implementation, CRM migration, and marketing automation services.

For PE portcos, SmartBug is strongest when the marketing problem is primarily a content and demand generation gap — when the portco needs to build a content engine, generate inbound leads, and nurture them through a structured funnel. The firm's scale means they can staff engagements quickly and maintain continuity through team transitions. The limitation is strategic depth at the operating model level: SmartBug excels at executing inbound marketing programs but does not position itself as a marketing operating model builder in the way that some competitors do. For portcos that need someone to run marketing, SmartBug is a strong choice. For portcos that need someone to redesign how marketing works, additional strategic capability may be required.

Directive — ⬤ Attribution & Analytics / ⬤ Demand Gen Execution

Directive has built a differentiated positioning in B2B performance marketing through what they call "Customer Generation" — a methodology that explicitly rejects the traditional MQL-to-SQL funnel in favor of financial modeling that connects marketing spend directly to customer acquisition cost and lifetime value. The firm serves B2B and SaaS companies, with published case studies spanning companies from Series A through public enterprises, and notably includes work with PE-backed companies.

Directive's attribution framework is one of the most rigorous in this landscape. Their published methodology describes a process that starts with financial modeling — calculating what a customer is worth, what the business can afford to pay to acquire one, and then reverse-engineering channel strategy from those economics. This is fundamentally different from the "spend on channels, measure MQLs, hope pipeline follows" approach that characterizes most B2B marketing agencies. For PE operating teams that think in terms of unit economics and payback periods, Directive's language and methodology are immediately legible.

The firm's execution capabilities span paid search, paid social, SEO, content marketing, and CRO (conversion rate optimization), with particular depth in LinkedIn advertising for B2B. Directive has also invested in PE-specific positioning, with published content addressing investor-backed company growth challenges and a client base that includes venture and PE-backed companies. The limitation is scope: Directive is a performance marketing firm, not a full-stack marketing operating model builder. They optimize the demand generation engine, but they do not build the broader marketing infrastructure — CRM configuration, marketing automation workflows, sales-marketing alignment processes, board reporting frameworks — that PE portcos often need.

Refine Labs — ⬤ Marketing Strategy / ⬤ Content & Messaging

Refine Labs, founded by Chris Walker, has become one of the most influential voices in B2B demand generation strategy. The firm's core thesis — that traditional lead generation through gated content and MQL handoffs is fundamentally broken, and that B2B companies should invest in creating demand through ungated content, dark social, and brand building — has reshaped how a generation of B2B marketers thinks about pipeline development. Their "demand creation" framework explicitly distinguishes between demand capture (paid search, intent data, direct response) and demand creation (content, community, brand, dark social), arguing that most B2B companies over-invest in the former and under-invest in the latter.

Refine Labs' methodology is strategy-first: the firm works with clients to redesign their demand generation approach from first principles, then executes against that strategy through content programs, paid media, and community engagement. Their published content — podcasts, LinkedIn posts, webinars — serves as both thought leadership and a proof-of-concept for their own methodology, demonstrating the content-led demand creation approach they prescribe for clients.

For PE portcos, Refine Labs is strongest when the marketing problem is strategic, not tactical — when the portco is spending heavily on lead gen but pipeline quality is poor, when the sales team complains that marketing leads do not convert, or when the brand has no meaningful presence in the market despite significant advertising spend. The limitation is that Refine Labs' philosophy requires organizational commitment: shifting from MQL-based marketing to demand creation means changing how marketing is measured, which requires buy-in from the operating partner and board. If the PE governance structure demands MQL counts and lead-to-opportunity conversion rates as the primary marketing KPIs, Refine Labs' approach will create friction with the reporting framework.

Ironpaper — ◕ Demand Gen Execution / ◕ Content & Messaging

Ironpaper positions itself as a B2B growth agency focused on lead generation, content marketing, and digital strategy for technology and professional services companies. The firm's approach is conversion-oriented — their published methodology emphasizes generating qualified leads and converting them through structured nurturing programs, with a focus on measuring marketing's contribution to sales pipeline. Ironpaper has built particular depth in content marketing, producing case studies, whitepapers, and blog programs designed to attract and convert B2B buyers.

The firm's published case studies show measurable improvements in lead volume, lead quality, and conversion rates for B2B clients. Their methodology is practical and execution-focused — less theoretical framework, more "here is how we will generate leads and feed your sales team." Ironpaper also offers web design and development services, which is relevant for portcos whose websites are not optimized for conversion.

For PE portcos, Ironpaper is a solid choice when the immediate need is pipeline volume — when the sales team needs more at-bats and the marketing function is not generating enough qualified opportunities. The firm is less suited for portcos that need a full marketing operating model redesign or deep marketing technology infrastructure work. Ironpaper operates at the execution layer, and does it well, but operating partners looking for a firm to architect the entire marketing function should look elsewhere for the strategic layer.

Pavilion — ◕ Marketing Strategy / ◕ PE Integration

Pavilion (formerly Revenue Collective) is a membership community and advisory organization for go-to-market executives, including a dedicated marketing track covering CMO development, demand generation strategy, and marketing leadership. Pavilion is not a traditional agency or consultancy — it is a community-based model where members access peer learning, structured programming, executive education, and advisory services through membership rather than project-based engagements.

Pavilion's value for PE portcos is less about execution and more about capability. For portcos that need to upskill their marketing leadership, build a peer network for their CMO, or access structured frameworks for marketing strategy, Pavilion provides a resource that traditional agencies do not. The organization's GTM-focused programming covers topics directly relevant to PE portco marketing: building pipeline, aligning marketing with sales, measuring attribution, and scaling marketing teams.

The limitation is clear: Pavilion does not execute. It does not run campaigns, build MarTech infrastructure, or produce content. Its value is in the strategic and leadership development layer — making the marketing leader more effective, not replacing them. For PE operating teams, Pavilion is a complement to an execution partner, not a substitute for one. The PE integration is notable because Pavilion's membership includes many executives at PE-backed companies, and the organization's programming increasingly reflects the specific challenges of marketing in a PE-ownership context.

Cortado Group — ⬤ Marketing Strategy / ⬤ Marketing Ops / ⬤ PE Integration

Cortado Group approaches marketing execution for PE portfolio companies as a full operating model problem — not a campaign optimization exercise, not a channel strategy engagement, but a ground-up build of the marketing infrastructure, process, measurement, and execution capability that the value creation plan requires. The firm's Marketing Execution Sprint is designed for the specific scenario that PE portcos face: a marketing function that was built for the founder era, a value creation plan that demands 2–3x pipeline growth, and a timeline measured in quarters rather than years.

What distinguishes Cortado from the agencies and consultancies in this landscape is scope integration. The firm has an in-house development team and works across both HubSpot and Salesforce, which means they can build the MarTech infrastructure — CRM configuration, marketing automation, attribution systems, reporting dashboards — rather than just recommending what someone else should build. Their FIRE Framework (Frequency, Intensity, Risk, Evidence) provides a structured methodology for prioritizing marketing initiatives, ensuring that limited resources are deployed against the highest-impact activities first. This is particularly relevant in PE contexts where the operating partner wants to see measurable pipeline impact within the first 90 days, not a six-month brand-building campaign that may or may not produce attributable results.

Cortado's PE integration is the deepest in this landscape. The firm works with PE deal teams and operating partners as a core part of its practice, understanding the governance cadence — quarterly board reporting, value creation plan milestones, hold period timelines — that shapes how marketing is evaluated in a PE-owned company. Their team builds what the portco cannot build internally, trains the internal team to operate the systems, and designs for handoff rather than dependency.

The honest limitation: Cortado is not the largest firm in this landscape. For portcos that need a 20-person agency team running content production, paid media, and SEO simultaneously across multiple business units, a scaled agency like SmartBug or Directive may provide more execution bandwidth. But for portcos that need someone to build the marketing operating model from scratch — the systems, the processes, the measurement infrastructure, the demand gen engine — and do it on a PE timeline, Cortado is built for exactly that engagement.

Heinz Marketing — ◕ Marketing Strategy / ◕ Demand Gen Execution

Heinz Marketing, led by founder Matt Heinz, is a B2B marketing consultancy and agency focused on pipeline-oriented marketing strategy and execution. The firm's positioning is explicitly around "predictable pipeline" — the idea that marketing should be measured by its contribution to sales pipeline and revenue, not by impressions, clicks, or MQLs. Matt Heinz is one of the most recognized names in B2B marketing, with a substantial publishing presence (blog, podcast, books) that has made the firm a visible authority on pipeline marketing.

Heinz Marketing's published methodology spans demand generation strategy, content marketing, sales enablement, marketing automation, and account-based marketing (ABM). The firm offers both strategic consulting (go-to-market planning, pipeline strategy, marketing-sales alignment) and execution services (campaign development, content production, email marketing). Their client base includes mid-market and enterprise B2B companies across technology, professional services, and manufacturing sectors.

For PE portcos, Heinz Marketing's pipeline-first orientation is well-aligned with how operating partners evaluate marketing. The firm understands that marketing is measured by pipeline contribution and revenue attribution, not by activity volume. The limitation is infrastructure depth: Heinz Marketing is primarily a marketing strategy and campaign execution firm, not a marketing technology implementation firm. For portcos that need CRM reconfiguration, marketing automation builds, or custom reporting infrastructure, additional technical resources may be needed alongside Heinz Marketing's strategic and campaign capabilities.

Demand Spring — ⬤ Marketing Strategy / ◕ Marketing Ops

Demand Spring is a revenue marketing consultancy that focuses on connecting marketing strategy to revenue outcomes through what they describe as a "Revenue Marketing Transformation" approach. The firm's methodology addresses marketing strategy, content marketing, marketing automation, marketing operations, and analytics — with a particular emphasis on building the operational infrastructure that connects marketing activity to revenue attribution.

Demand Spring's published content emphasizes the disconnect between marketing activity and revenue measurement — a theme that resonates directly with the PE portco experience. Their service offerings include marketing strategy development, content strategy and creation, marketing automation implementation and optimization, demand generation program design, and marketing analytics and reporting. The firm has particular depth in marketing automation platforms, including expertise across Marketo, HubSpot, Eloqua, and Pardot.

For PE portcos, Demand Spring is strongest when the marketing problem spans both strategy and operations — when the portco needs not just a demand generation plan but also the marketing technology infrastructure and measurement systems to execute and attribute it. The firm's multi-platform marketing automation expertise is a differentiator: for portcos running Marketo or Eloqua (common in enterprise B2B), Demand Spring offers platform depth that HubSpot-native agencies cannot provide. The limitation is execution scale: Demand Spring positions itself as a consultancy rather than a large-scale execution agency, which means portcos with high-volume content production or paid media management needs may require supplemental agency resources.
