First 90 Days: Demand Gen Takeover Checklist
What to audit, fix, and build when you inherit a B2B marketing function
Audit before acting. The first 90 days as a marketing leader is diagnostic, not launch. Every new VP/CMO we talk to wants to show impact in month one by shipping a campaign — and every one who actually succeeds spends that month fixing the CRM, auditing spend, and getting a real baseline first.
See why we fix your CRM before we spend and paid media isn't the problem for the argument.
42's First 90 Days Take
Don't launch anything new in the first 30 days. Audit everything. Understand what's working, what's broken, what's unmeasured. The worst thing a new marketing leader can do is "make their mark" before understanding the current state.
The biggest mistake we see? Trying to change everything at once. The biggest success factor? Having clear baseline metrics before any changes.

Week 2: Performance Baseline
Week 3: Pipeline Reality
Week 4: Competitive Snapshot
Red Flags: Escalate Immediately
If you find any of these during your audit, escalate to leadership before your 30-day mark:
Phase 2: Days 31-60 Quick Wins
Now that you understand the landscape, it's time to stop the bleeding and optimize what's already working. These are high-impact, low-risk changes.
Week 5-6: Stop the Bleeding
Week 7-8: Optimize What's Working
- Pause anything with CAC > 2x target (immediate savings)
- Fix broken tracking (you can't optimize what you can't measure)
- Add negative keywords and audience exclusions (low-effort, high-impact)
- Reallocate budget from worst to best performers (show ROI improvement)
Phase 3: Days 61-90 Build the Foundation
The final phase is about building sustainable systems and making strategic bets. This sets you up for long-term success.
Week 9-10: Systems & Process
Week 11-12: Strategic Bets
Your 90-Day Presentation Template
When you present to leadership at the end of 90 days, structure it like this:
1. What I Found (Days 1-30)
2. What I Fixed (Days 31-60)
3. What I'm Building (Days 61-90)
Common Mistakes We See (From 50+ Transitions)
New leaders feel pressure to "make their mark." But launching 5 initiatives means finishing 0 of them well. Focus beats breadth.
If you can't prove what the numbers were before you arrived, you can't prove you improved them. Export everything on day 1.
Your sales team knows which leads convert and which don't. If you don't interview them in Week 3, you're missing the most important signal.
More budget doesn't fix broken tracking, bad targeting, or misaligned MQL definitions. Fix the foundation first, then scale.
What Successful Transitions Have in Common
The best leaders export CAC, conversion rates, and channel performance before touching anything. This becomes your "before" snapshot.
Understanding what sales thinks about marketing leads (even if critical) gives you the roadmap for what to fix first.
Share your audit findings at Day 30 and get sign-off on your quick wins and strategic bet. No surprises means no resistance.
Leaders who launch one initiative and show measurable results build more credibility than those who launch five and show none.
