GTM Engineering & Salesforce
Architecting CRM data models, platform migrations, and API integrations that turn a sales tool into revenue infrastructure.
Hello, my name is
Marc Hummel and
I’m a Marketer
I’m a B2B marketer who builds the systems behind growth. Over 14 years I went from campaigns and content to architecting the Salesforce, automation, and AI workflows that scale revenue. Based in Jersey City Heights. More about me →
What I Do
Marketing Automation
Pardot / Marketing Cloud implementation, lead scoring, and lifecycle programs that scale utilization without adding headcount.
AI-Powered Growth
Shipping production AI with the Claude API and Claude Code — from real-time lead qualification to internal tools I build myself.
Work Experience
Sr. Marketing Manager
Built a B2B fintech’s entire GTM stack from scratch: migrated Salesforce from Classic to Lightning, designed custom data models, and integrated the Infinicept payments API. Stood up Pardot end-to-end and scaled from ~10 to 40+ Salesforce users (4× utilization). Grew a direct-to-merchant acquisition channel from 0 to 595 merchants across 50+ growth experiments, and built a Claude-API system to qualify leads and flag fraud before they hit the sales queue.
Marketing Manager
Owned marketing automation and demand gen for a virtual-tour platform. Took over and rebuilt the Pardot instance, and produced client case studies — including a visual, brochure-style piece on how Pilot Flying J used the product to support recruiting.
Content Marketing Manager
Ran content and demand-generation programs for a personalization / ecommerce platform — ebooks, thought leadership, and seasonal campaigns (Kentucky Derby, Pi Day) that drove pipeline and engagement.
Copywriter
Wrote online content across web, on-air text, and email newsletters for a top-10 North American ecommerce property — building omnichannel content skills across electronics, home, beauty, and fashion.
Selected Work
Built with AI & Code
Home Supply Predictor
A private, installable PWA that predicts what’s about to run out around the house — from plain-language logging, with no forms or stock counts. Next.js + Supabase + Claude: the LLM is the entire interface, while unit-tested TypeScript does the prediction math.
Read the case study →Riff — AI Growth Triage
Paste a raw growth idea — a tweet, a Discord message, a link — and Riff returns a finished marketing brief (classified, measured, planned, drafted) in seconds. Next.js + Claude structured outputs, with metrics conditional on marketing type.
Read the case study →AI Cold-Email Workflow
An n8n flow that scrapes a company’s homepage, has Claude draft a tailored cold email, and drops it straight into the rep’s Gmail drafts.
Watch on Loom →Hummelify
Built with Claude Code: upload a selfie and it reimagines your face as a Hummel figurine, then emails it to you — a proof-of-concept for beautiful, AI-native forms.
Launch Hummelify →Email List Cleanser
A browser-based tool that validates contacts before a Marketing Cloud (MCAE) import — catching bad emails, field-length violations, and dupes. Data never leaves your machine.

Small Business Report
A long-running report analyzing CardFlight’s 125,000+ merchant portfolio. I found the hook in the data, shaped each narrative with BizOps, and wrote every edition — launched for awareness at the start of COVID-19.
View project →Pilot Flying J Case Study
How a national truck-stop chain used VR to attract and train talent. Writing, content strategy, interviewing, and design direction, at YouVisit.
Download PDF →Thrive TRM Ebook
A bottom-funnel ebook educating executive-recruiting pros on the problems Thrive TRM solves. Industry research, narrative, and writing (freelance).
Download PDF →Curiosities
iOS Shortcuts
Shortcuts I built to run across my iPhone, Watch, and HomePod — small proofs of a curiosity-and-tinkering habit.
View shortcuts →Do Ideas Spread Like Viruses?
My UPenn Master’s capstone: interviews plus an interactive website exploring how ideas propagate. A little broken now, but worth a look.
View project →bminus
A bike-apparel company a friend and I founded in 2004 around one idea: “bicycles are for lovers.” Hundreds of hand-packed tees later, we mailed the last parcel in 2011.
