Why teams hire a Chameleon fractional Growth Marketing Manager
Manager-level execution, not director-level strategy
A Growth Marketing Manager is IC-leaning: running paid channels, designing experiments, building lifecycle programs hands-on. Different from a Director (managing a team) or VP (managing strategy). Our managers ship work in tools, not slides.
Cross-channel hands-on capability
Most "growth" hires specialize in one channel. Our managers are cross-channel by background: fluent in Meta and Google paid, Klaviyo and HubSpot lifecycle, Mixpanel and Amplitude analytics, conversion testing platforms.
Experimentation discipline
Growth without experimentation is just paid media. Our managers run real experimentation programs: hypotheses, holdouts, power calculations, results that inform the next experiment instead of justifying the last one.
Why hire a fractional Growth Marketing Manager from Chameleon Collective
Growth Marketing Manager is the IC-level seat that actually ships growth work. Most companies in the $5M-$50M revenue range need this seat more than they need a Director or VP of Growth: they don't yet have a growth team to manage, but they desperately need someone senior running the paid programs, lifecycle, and experiments. Most of those companies misfire by hiring a Director who delegates execution to junior staff, or by hiring a junior IC who can ship but lacks the senior judgment to set strategy. A fractional Growth Manager fills the gap: senior hands-on execution, with the strategic judgment to choose the right experiments.
IC-level senior is rarer than it sounds
The market for senior individual-contributor growth operators is thin because the career path usually moves people into management. Most senior growth talent ends up running teams; fewer stay hands-on. Our roster includes senior operators who prefer IC work: they ship campaigns, configure tools, write copy, run experiments, and don't need a team underneath them to deliver. That's exactly the shape most growth-stage companies actually need.
Experimentation is the discipline that compounds
The thing most growth functions get wrong is treating experimentation as occasional tactical optimization rather than continuous discipline. Our managers run experimentation as the operating cadence: a steady stream of hypotheses, prioritized by expected value, executed with statistical discipline, and synthesized into a learning record that informs the next experiment. Programs that run experimentation as discipline compound; programs that don't plateau.

Frequently asked questions
Common questions from teams evaluating fractional Growth Marketing Manager engagements.
Manager is IC-leaning: runs channels and experiments hands-on. Director is management-leaning: leads a team, sets strategy, manages agencies. Smaller companies usually need a Manager more than a Director (no team to manage yet). Larger companies need both.
Yes. That's the whole point of the IC-level shape. Campaign setup in Meta/Google, ESP configuration, dashboard build, experiment configuration in tools: all hands-on by the senior operator.
Week one: audit of paid programs, lifecycle, analytics setup. Weeks 2-4: 90-day plan with prioritized experiments. Weeks 4-12: execution. Most engagements ship the first 5-10 experiments inside the first quarter.
Most engagements run $10K-$22K per month at two to three days per week. Lower than Director or VP engagements because the IC-leaning role typically runs at a more accessible day rate.
Yes: partnering with an existing junior IC team or freelance roster is common. The fractional Manager provides senior judgment and direct execution on the highest-leverage work; the team handles lower-leverage execution.
Yes. PLG growth has its own patterns (in-product growth, expansion mechanics, freemium economics) and we have operators who specialize.
Directly. Chameleon Collective is a senior-only collective.
