Senior growth ownership on a lean budget
Part-Time CMO
Led growth at cnvrg.io before its acquisition by Intel.
A two-day-per-week schedule is one example of part-time senior growth leadership. The question is not whether it is enough in principle - it is whether the agreed schedule and responsibilities cover what your company specifically needs right now. This page examines that scope question.
What two days a week of senior growth leadership gets you
"Two days a week from a senior operator beats five days from someone learning on your budget. Seniority compounds faster than hours."
Yaniv Goldenberg, fractional growth operator
A part-time schedule should be defined in weekly hours and responsibilities rather than treated as a fixed monthly allocation. Senior time can cover strategy, decisions, creative direction and analysis. What you get depends on the agreed scope and the execution capacity already inside your company.
Assess the actual backlog, decision frequency, personal implementation and team capacity before choosing a part-time schedule. For example, campaign builds and launch approvals can require a different working rhythm from a periodic reporting review. We define weekly coverage, responsibilities and escalation owners rather than infer sufficient capacity from headcount alone.
I lead strategy and personally deliver the priorities agreed for this part-time CMO engagement. Advisory is the separate advice-only option, with implementation owned by your team or a separately agreed service. Before starting, we define the work I carry out, the capacity each owner supplies and the dependencies.
At Elementor I led acquisition during company growth from $200K to $20M ARR, alongside the wider team. For a part-time engagement, I agree the strategy, work I personally execute, team responsibilities and review cadence for your client or project scope.
What a part-time CMO can own at 2 days/week
Channel strategy and investment allocation. Attribution model and reporting. Creative brief review and direction. Agency management. Weekly team direction. Board-level growth dashboard. Hiring specification if you are adding to the team. Quarterly planning. The decision-making layer of the growth function.
What part-time cannot replace
The agreed capacity must cover the selected work: campaigns, copy, conversion changes, lifecycle, measurement and leadership can all be personally delivered within scope. Name any additional daily production, approval or team-management coverage and its owner before starting. A part-time schedule cannot provide unlimited work.

Know the limits
When part-time CMO stops being enough
Part-time breaks when the growth function needs more senior time than the agreed schedule provides, or when the decisions require more frequent presence than the agreed part-time schedule supports.
The work requires sustained executive coverage and team leadership
At seed stage and early traction, limited senior direction may be sufficient when the scope is narrow and execution capacity already exists. At $3M ARR moving fast, you might be making channel pivots weekly, launching new markets and managing a growing team. Part-time coverage can constrain the speed. Assess whether broader coverage or a hire is needed for the actual workload; the decision should follow the scope and team capacity.
You need delivery beyond the agreed scope
If you need advice without implementation, choose the separate Advisory offer. In a part-time CMO engagement, I lead strategy and personally carry out the agreed work. If your budget is $8-12K per month total and you are trying to cover both strategic leadership and execution with a single engagement, the required leadership and delivery must fit the actual capacity we agree. If the brief is narrower, we can scope my consulting or a service-specific build around that channel or implementation task. We agree deliverables and capacity before pricing the work.
The growth problem is primarily a product problem
Retention problems can involve product value, onboarding, acquisition quality, expectations or customer support. I personally investigate the agreed evidence and implement selected growth, journey and lifecycle work with the appropriate product owners. The diagnosis should determine the next intervention rather than exclude retention work from the engagement.
The company profile where part-time CMO produces the best return
Part-time can fit when an agreed schedule covers the leadership and personal implementation needed, with named owners for other work. We assess the objective, decision frequency, authorized access, current capacity and observation window. ARR, team size and PMF labels alone do not establish the best return or eligibility.
At Riverside I led paid acquisition, testing, measurement and budget allocation during reported +337% Net MRR growth on a $450K monthly paid budget. The $100M+ in total ad spend managed across roles figure covers multiple engagements. These historical facts show operating experience rather than proof that a part-time strategy change alone caused the company outcome.
The broader comparison of all outsourced models is on the outsourced CMO hub page. For a lighter engagement, the virtual CMO model runs async-first at similar pricing. For more bandwidth, the interim CMO model covers near full-time needs.
FAQ
Questions about part-time CMO scope and fit
Is a part-time CMO the same as a fractional CMO?
Part-time and fractional are often used interchangeably and in practice they describe the same engagement model: a senior CMO working at reduced bandwidth, typically 1-2 days per week. When I use fractional I mean the same thing. The distinction that matters is not the label but the scope: what the CMO owns, how many hours per month, and what the success criteria are.
What does a part-time CMO actually do each week?
In a typical two-day-per-week engagement: one day covers strategy and decisions (channel review, attribution analysis, campaign direction, team weekly). One day covers output (creative brief writing or review, reporting, board update preparation, agency management). The split adjusts based on where the growth function is in its cycle.
How long does a part-time CMO engagement typically last?
Duration and review points depend on the work, continuity needs, observation window and contract. We define what ongoing ownership or a handoff requires and reassess capacity as the business changes. A fixed six- to eighteen-month term is not a condition of useful work.
Can a part-time CMO manage a marketing team?
Yes, when team leadership and personal delivery fit the agreed schedule. Review the actual decisions, one-to-ones, feedback, approvals, geography and backup coverage rather than use a universal team-size threshold. We name responsibilities and any additional management capacity needed.
What is the minimum company size for a part-time CMO to make sense?
There is no universal ARR floor. A focused investigation, launch, campaign, system build or leadership mandate can be scoped at different stages. We assess the decision, resources, authorized access and implementation needed before agreeing the engagement.
Where does a part-time CMO engagement start?
It can start with a diagnostic. This is a full funnel audit before committing to ongoing work: what is broken, what is fixable, and what the part-time model can realistically own given your execution capacity. It has a fixed scope and fixed output, and you keep the plan. It is one-time, with an agreed delivery schedule.
When is a part-time CMO not the right choice?
A limited part-time schedule cannot cover unlimited daily production. I personally execute agreed priorities, and we define any additional capacity before starting. If growth is stalling because the product is not retaining users, strategy alone is not enough; the product and retention work must be included in the plan.
How is a part-time CMO different from advisory?
Advisory is a weekly senior review of your growth decisions, with async access between sessions. It is diagnosis, decisions and guidance only. A part-time CMO scope can include strategy, attribution, creative direction, channel ownership, team direction and board reporting. Advisory is right for companies with a VP of Marketing but no CMO-level strategic owner.
Do you take on several part-time CMO clients at once?
I agree the scope, time commitment and availability for each client or project before work starts. Availability changes over time, so a free slot is not something I can promise in advance. If you want to check where I stand, send me a message and I reply within 1 business day.
What happens on the scoping call?
The call is 15 minutes to know if part-time is the right model. You tell me your ARR, your team size, and what the growth motion looks like now. I tell you whether two days a week covers what you need, or whether a different model is the better fit. It is an honest scope assessment, with no pitch.
Is there a minimum contract length or notice period for a part-time CMO engagement?
Contract terms, including duration and notice period, are agreed per engagement. Ending a fractional engagement, which is the same model as part-time, involves no severance. We agree the scope, review points and contract terms before work starts.
