The B2B Marketing Function Setup Playbook

建設の順序
The Order of Construction
For the person doing the hiring. And the person being hired.
69% of startup project failures include a marketing problem. Most of those problems don’t start with a bad strategy. They start in the first 90 days of a first marketing hire, when neither side knows what “good” looks like.
This playbook runs both ways. If you’re hiring a B2B marketer, Part 1 is yours. If you just got hired as one, Part 2 is yours. Share it with whoever is on the other side.
Part 1: Before They Arrive
The Hiring Manager’s 10-Point Checklist
Your first B2B marketer can only go as far as the brief you give them.
Most companies skip this. They hire someone, expect output in week one, and then wonder why nothing’s landing. The first marketer walks into a vacuum: no ICP, no access, no idea what success looks like.
Fix that before day one.
# | What to Have Ready | Why It Matters |
|---|---|---|
1 | Written ICP (even a working draft) | They can’t build messaging without a starting point |
2 | CRM data and closed-won/lost analysis | Customer research starts day one |
3 | Budget clarity and who controls it | Marketers without budget control waste the first month asking for money |
4 | Audit of existing assets | Content, ads, analytics: what exists, what worked, what was abandoned |
5 | At least 5 sales call recordings | The fastest route to understanding how buyers actually talk |
6 | Your competitive landscape | Who you’re tracking and why |
7 | Written definition of success at 90 days | Non-negotiable. Set it before day one |
8 | Introductions to Sales, CS, and Product | Not just the CEO. Marketing aligns with everyone |
9 | Full tech stack access from day one | CRM, analytics, ad accounts, email. Late access wastes weeks |
10 | Honest stage assessment | Early-stage vs. mid-market changes every priority |
One debate worth having before you post the role: some argue you shouldn’t hire a marketer until you’ve validated demand generation manually. That’s reasonable for short-cycle B2B. For longer-cycle deals, a marketer who builds the foundation in months one through six compounds over 12 to 18 months. Know which stage you’re at before you decide.
Part 2: The First 90 Days
The Marketer’s Order of Operations
The first 90 days in B2B marketing is not about output. It’s about building the foundation that makes output matter.
Most first marketers face pressure to ship campaigns before they’ve understood the ICP, the sales motion, or what’s been tried before. That’s how you generate activity without signal. Here’s the sequence that actually works.
Period | Focus | Key Deliverables |
|---|---|---|
Days 1-30 | Understand before you build | ICP audit, 5+ customer interviews, sales call review, channel audit, competitive mapping |
Days 31-60 | Build the foundation | Updated ICP and positioning doc, website quick wins, content strategy, 1 demand gen channel live |
Days 61-90 | Generate signal | First campaigns live, reporting baseline set, 90-day review delivered |
Month 1: Understand
Don’t touch the website. Don’t launch ads. Listen first.
Shadow at least 5 sales calls. You’re listening for the words buyers use, not the words marketing has been using. That gap is usually where the positioning problem lives.
Audit everything that exists: content, ad accounts, analytics, previous campaigns. What worked, what was abandoned, and what never got properly measured.
Map the competitive landscape. Who ranks for your keywords, who’s active on LinkedIn, what are their positioning claims, and where are they weak.
Month 2: Build
The biggest waste in early B2B marketing: running campaigns before the foundation is solid.
Write or rewrite the ICP and positioning document. Get sign-off from Sales and CS, not just the marketing lead. If Sales doesn’t recognise the ICP on paper, the document is wrong.
Fix the highest-impact website issues. Most B2B websites have 3 to 5 things actively hurting conversion that take days to fix. Find them before you spend a pound on traffic.
Pick one demand gen channel and go deep. Not shallow on three.
Month 3: Signal
These first campaigns don’t need to win. They need to generate learning.
Launch with clean tracking from day one. If you can’t attribute it, you can’t optimise it.
Set up your five core weekly metrics and start the clock: pipeline generated, CAC, channel-level performance, content engagement, and revenue contribution. These are what you report at 90 days.
Deliver the 90-day review. What you found, what you built, what you’d prioritise in the next six months. This is how you earn the trust to do more.
Part 3: The Hire Decision
The Debate Most Founders Get Wrong
Almost every startup hires for pipeline first. Most should have hired for positioning first.
The PMM vs. demand gen debate runs in every B2B hiring thread. Here’s the honest answer for challenger brands with no existing marketing function:
Hire a T-shaped demand gen marketer with PMM instincts. Someone who can write the positioning document in month one and run the first LinkedIn campaign in month two. Specialists come later, once you know which channels actually work.
The single most important interview question:
“Tell me about something you built from scratch rather than inherited.”
That separates builders from optimisers. At this stage, you need a builder.
Five more worth asking (free, no paywall):
What’s your process for understanding a new ICP when you arrive somewhere new?
Walk me through a campaign you killed and why you killed it.
What’s the first channel you’d test in our market and how would you validate whether it’s working?
How do you decide when to go deep on one channel vs. testing multiple?
What does your first 30 days look like before you launch anything?
Part 4: The AI Stack
What Changes When You Get This Right
One B2B marketer with the right AI tools can do the work that used to take three.
Not a pitch. The operational reality of building a marketing function in 2026.
What AI handles well in this context: competitive and keyword research, content drafting and iteration, campaign performance analysis, reporting, audience intelligence, and market monitoring.
What it doesn’t replace: customer interviews, positioning judgment, sales relationships, and the instinct to kill things that aren’t working.
If you’re building a B2B marketing function and want the AI infrastructure sorted from week one, DOJO AI is built for exactly this: giving a first or solo B2B marketer enterprise-grade intelligence without the complexity.
What to Do Next
For hiring managers: Run the 10-point checklist before your marketer’s start date. If you’re missing more than three items, set a prep sprint.
For first B2B marketers: Share Part 1 with whoever hired you. Alignment on what “good” looks like at 90 days is worth more than any campaign you launch in week one.
