Fractional CMO playbook for AI infrastructure
AI infrastructure companies usually do not lose because the market is too small; they lose because the proof is too hard to find.
Playbooks
Industry & stage playbooks
What fractional CMO engagements actually look like by company shape, broken down by industry and stage.
By industry
Fractional CMO playbook for AI-first SaaS
AI-first SaaS companies rarely fail because the demo is weak; they fail because the go-to-market system cannot turn attention into trusted adoption.
Fractional CMO playbook for B2B SaaS
B2B SaaS growth usually breaks at the seam between product-led signals and the sales-led handoff: product activity says one thing, CRM stages say another.
Fractional CMO playbook for consumer subscription
Consumer subscription companies do not break because the team forgot how to buy media; they break because acquisition gets asked to carry a retention problem.
Fractional CMO playbook for cybersecurity
Cybersecurity growth usually breaks when the company keeps scaling claim-based marketing after buyers have moved into proof-based evaluation.
Fractional CMO playbook for data & analytics
For Series B and beyond data companies, growth usually breaks when the product is technically strong but the buying motion is too hard to understand.
Fractional CMO playbook for developer tools
Developer tools growth usually breaks when the company tries to market like a SaaS company instead of earning trust like an infrastructure layer.
Fractional CMO playbook for DTC e-commerce
DTC e-commerce growth usually breaks when the business keeps managing marketing like acquisition arbitrage after the market has moved on.
Fractional CMO playbook for enterprise software
Enterprise software growth usually breaks when marketing keeps optimizing for lead volume after the business has become an account-led, committee-driven motion.
Fractional CMO playbook for fintech
Fintech growth usually breaks when the company tries to scale demand faster than trust, compliance, and sales readiness can support.
Fractional CMO playbook for healthtech
Healthtech growth usually breaks when the company treats a multi-buyer market like a single-message problem.
Fractional CMO playbook for marketplaces
Marketplace growth usually breaks when the company treats marketplace marketing as one funnel instead of two connected operating systems.
Fractional CMO playbook for PE-backed tech
PE-backed tech companies do not usually need louder marketing; they need a cleaner commercial system.
Fractional CMO playbook for post-acquisition tech
Post-acquisition tech companies rarely need “more marketing” first; they need marketing reconstituted around the new operating reality.
Fractional CMO playbook for vertical SaaS
A fractional CMO for vertical SaaS is most useful when the company has product-market proof but the market still does not know what category to put it in.
By stage
Fractional CMO playbook for post-acquisition reset
Post-acquisition marketing is the cleanest reset window a company gets: positioning, agencies, team structure, KPIs, funnel definitions.
Fractional CMO playbook for pre-IPO
Pre-IPO marketing is not a rebrand, a campaign sprint, or a louder demand generation plan.
Fractional CMO playbook for seed stage
Seed stage marketing is a positioning and ICP exercise, not a channel exercise.
Fractional CMO playbook for Series A
Series A is where the company decides whether marketing is a function or a budget line, and that decision compounds for years.
Fractional CMO playbook for Series B
Series B marketing is where ICP discipline either compounds or breaks.
Fractional CMO playbook for Series C
Series C marketing is no longer about proving that channels can create pipeline; it is about proving the company can lead a category.
