Framework
Fuel vs. Engine: The Marketing Mental Model
"Forget all the sub-functions—product marketing, content, demand gen. Just think: you need fuel and you need an engine. The question is: where do you have the biggest challenge right now?"
What Goes Where
Fuel & Engine Examples
FUEL (Things You Create)
Blog posts, long-form content
Website copy & positioning
Videos, webinars, podcasts
Templates, tools, calculators
Product marketing & messaging
ENGINE (How You Distribute)
Email setup, segmentation & drips
SEO strategy & technical optimization
Paid advertising & channel strategy
Community & distribution channels
Marketing ops & HubSpot setup
The hybrid zoneMany things are BOTH fuel and engine. Your community is fuel (content) + engine (distribution). Your website copy is fuel, but your technical SEO is engine. Email copy is fuel, but segmentation rules are engine.
When to Hire What
Reading Your Growth Constraint
If you're top-down sales: You likely have SDRs (engine first). Now hire for fuel—positioning, messaging, content that makes the SDR emails work.
If you're PLG: Your engine is broken (poor website conversion, funnel leaks). Hire someone who owns inbound + lifecycle email + web optimization.
If you've built lots: Check: Is your content performing? Do you know your positioning? If no, you need fuel first. If yes but distribution sucks, hire engine expertise.
Simple diagnostic
Ask yourself: What are my top-performing pieces of content? Can I articulate who my product is for, why it's better, key benefits, how we compare to competitors?
If you can't answer: You need fuel—hire a product marketer or content strategist.
If you can answer: You need engine—hire someone focused on distribution, email, ads, or SEO.
First Hire Profiles
Archetypes to Find
The fuel-first generalist: Can write, position, and own the narrative. Best for early stage when you have no positioning.
The engine builder: Growth marketing DNA. Owns email, paid, or SEO from day one. Pairs with founder as your "fuel."
The business model expert: More valuable than industry experience. Someone who's done B2B SaaS top-down, or PLG, or enterprise. The activities are different.
Red flag: Hiring mismatchYou hire a specialist (deep paid search person) when you needed a fuel strategist. Or you hire a brand marketer when your product messaging is broken. Match the hire to your constraint, not your intuition.
Contrarian Takes
Marketing Hiring Myths
✗You need someone with X industry experienceINSTEAD →✓ Business model matters WAY more. A PLG expert is more valuable than a SaaS generalist who's never done bottom-up growth.
✗Your first marketer should do "all of marketing"INSTEAD →✓ No. They should own your biggest bottleneck—fuel OR engine. Trying to do both first = doing neither well.
✗Product led growth means no marketing teamINSTEAD →✓ PLG actually means BIGGER marketing earlier. No large sales team = larger marketing team doing 1-to-many communication.
✗Marketing and product are separate functionsINSTEAD →✓ The marketing-to-product handoff (signup flow → onboarding) is as critical as marketing-to-sales. Treat it like a paid customer handoff.
