Hi, I’m John. I build growth engines where none existed.

15+ years across B2B demand generation, ABM, and marketing operations — with 42% SQL growth, 26% pipeline growth, and $1M in wasted ad spend eliminated to show for it.

Strategic and hands-on: from GTM strategy to the campaigns, workflows, and automation that run it. Fluent in the modern marketing stack and AI.

Differentiators & Attitude

Full-Stack Marketer

Hands-on knowledge across demand gen, content, SEO, paid media, social, email, automation, analytics, and more. Both strategic and tactical - from designing a go-to-market plan and executing the day-to-day campaigns.

Technical Expertise

HubSpot automations, data enrichment workflows, Clay, conversion tracking, integrations, tag management, cookie consent, AI. I'm as comfortable on the technical side of marketing as the strategic and execution.

Strategic Thinking

Big picture perspective using customer research, business priorities, and analytics to focus efforts effectively.

Calm, Curious, Driven

I thrive in ambiguity, adapt quickly, and bring a thoughtful, audience-first lens to every marketing challenge.

Problem-Solver at Heart

Whether it’s pipeline breakdowns or messy handoffs, I’m wired to dig in, connect the dots, and move things forward.

Hands-On & Humble

I lead with data and empathy, not ego. Known for being collaborative, curious, and calm under pressure. Especially when things get messy.

GTM Engineering

The part most marketing leaders outsource. Systems I designed and shipped myself:

The "job ad chaser" lead pipeline

Apify scrapes new job postings from Indeed and LinkedIn. Clay filters, classifies, and enriches each one with company data and hiring contacts. A scheduled Google Cloud (Cloud Run) job pushes qualified, deduped leads into Bullhorn and Lemlist daily, auto-assigned to sales. Designed and built end to end.

Attribution where none existed

Co-built a revenue attribution framework inside a Fortune Global 500 that tied marketing to revenue for the first time — enabling a $1M reduction in ad spend with zero negative impact on sales pipeline. Later built a hybrid measurement framework at Atrium to demonstrate marketing's pipeline contribution to executive leadership.

AI-operated marketing workflows

Repeatable audits, reporting, and campaign optimization run through Claude Code with integrations into Profound, ahrefs, LinkedIn Ads, and Google Ads — plus enrichment and automation workflows in Clay and n8n.

Experience & Impact

The majority of my experience has been in-house, with additional work in consulting, freelance, and agency settings. Industries include: HR/HR Tech, professional services, and SaaS.

Sr. Director of Digital Marketing

Atrium

Created and implemented the company's first true ABM and demand generation frameworks and campaigns, resulting in 42% SQL growth and 35% increase in high-intent (hand-raiser) leads YoY. Also designed and built an automated lead-gen pipeline (Apify > Clay > Google Cloud > Bullhorn) delivering qualified, deduped leads to sales daily.

Director of Demand Generation

Object Edge

Increased pipeline by 26% YoY through strategic development of targeted content, webinars, virtual events, and integrated advertising campaigns.

VP Digital Marketing

Adecco Group North America

Over a nearly 12-year tenure at the Adecco Group, I created and led the digital and content marketing shared services teams for the North American market within the Fortune Global 500, developing scalable strategies across multiple business units. Co-developed a revenue attribution framework that enabled a $1M reduction in ad spend with zero negative impact on sales pipeline.

Head of Digital Marketing

FAQs

How do you use AI?

To accelerate research, analysis, operations, and production. And yes, I’m one of those Claude Cowork/Code people. Examples include:

  • Contact and account workflows, automation, and enrichment with n8n, Clay, and Apify.

  • Audit, review, and other repeatable marketing and operations workflows (and naming conventions) with Claude Code, skills, and integrations with Profound, AHREFS, LinkedIn Ads, Google Ads, and more.

  • Campaign and advertising optimization and reporting with Claude Code and platform APIs.

  • Video transcription and editing, audio creation and editing with VEED and Descript.

Why do you call yourself a full-stack marketer?

Though my breadth of skills, mix of strategic + tactical, cross-channel fluency, and being data-driven and adaptable, I can design a go-to-market plan and also execute the day-to-day campaigns. And with a marketing mix to run integrated programs from idea to pipeline impact.

What is your approach to ABM?

I'm a big fan of Emily Kramer's approach outlined in The Shift to Account-Driven GTM. From building the foundation, layering on account-driven campaigns and workflows, and setting up signal-based campaigns, it’s a great approach. And to add my 2 cents: A legacy ABM platform like 6sense is NOT required, but more modern, decoupled tools to help capture and activate contact-level intent can be extremely powerful.

What motivates you?

I'm driven by impact and doing meaningful work.
