Fractional CMO for B2B SaaS
A fractional CMO for B2B SaaS is a senior marketing leader who runs your growth function part-time, on a retainer, instead of joining full-time. You get the strategy, the team direction, and the revenue ownership of a chief marketing officer, at a fraction of the cost and commitment. Yaniv Goldenberg provides exactly this: a Fractional Head of Growth who takes B2B SaaS companies from traffic to revenue.
The job is not brand awareness. The job is pipeline, conversion, and ARR. Yaniv has managed $100M+ in budgets and built the growth engine that helped scale Elementor by 100x ARR. He owns the full funnel: acquisition, activation, and retention, measured against revenue, not vanity metrics.
What you get
- Full-funnel ownership: one leader accountable for traffic, signups, conversion, and MRR.
- A growth strategy tied to revenue, with clear targets and weekly reporting.
- Hands-on execution: paid acquisition, SEO, lifecycle, and conversion-rate work, not slide decks.
- Team leadership: hiring, briefing, and directing your in-house marketers and agencies.
- Analytics and attribution built so you can see what drives pipeline.
When to hire a fractional CMO for your SaaS
Hire one when you have product-market fit and budget, but no senior marketer to own growth. A full-time CMO costs $250K+ per year and takes months to find. A fractional CMO starts in days. The fit is strongest for Seed to Series B SaaS companies spending on acquisition without a clear revenue return. Yaniv has driven results like +337% MRR for SaaS clients by fixing the funnel, not just the top of it.
How a fractional CMO for B2B SaaS runs your first 90 days
The first 90 days set the trajectory. Yaniv Goldenberg, a Fractional Head of Growth, starts with an audit, not a campaign. In the first two weeks he maps the full funnel, pulls real numbers from your analytics, and finds where revenue leaks. Most SaaS teams have plenty of traffic and signups; the leak is deeper, between trial and paid, or between paid and retained.
From there the plan is sequenced, not scattered. Days 15 to 45 fix the highest-use break in the funnel. Days 45 to 90 build the repeatable acquisition and lifecycle motions that compound. Every action ties to a revenue target, with weekly reporting so you see movement instead of activity. This is the same discipline behind $100M+ in budgets managed and the growth engine that scaled Elementor by 100x ARR.
The metrics he owns are the ones that decide whether a SaaS business survives. Vanity numbers get cut from the report. What stays:
- CAC: the true cost to acquire a paying customer, by channel, not blended guesswork.
- Payback period: how many months until a customer repays their acquisition cost. Under 12 months is the goal for most B2B SaaS.
- MRR: net new monthly recurring revenue, split into new, expansion, and churned.
- Retention and net revenue retention: the single strongest signal of whether growth is real or rented.
- Conversion at each funnel step: visitor to signup, signup to activation, activation to paid.
These metrics connect. A low CAC means nothing if payback runs 20 months and retention is weak. Yaniv reads them together, the way every durable SaaS business is built. The research backs this up: studies in the Harvard Business Review show that retaining customers costs far less than winning new ones, and that small retention gains drive outsized profit. Growth that ignores retention is a treadmill.
The common founder mistakes are predictable, and expensive. Most come from treating marketing as a top-of-funnel problem when the real damage is downstream.
- Spending on paid acquisition before the trial-to-paid conversion works. You pay full price to fill a leaking bucket.
- Hiring junior marketers to set strategy. They execute well but cannot own the revenue number.
- Chasing traffic and impressions instead of pipeline and MRR.
- Measuring blended CAC, which hides the channels that lose money.
- Treating retention as a customer success job, not a growth lever. Churn quietly caps every acquisition gain.
Yaniv fixes the order of operations. He stabilizes conversion and retention first, then scales spend into a funnel that returns it. That sequence is why his SaaS work has produced results like +337% MRR. The goal is never more traffic for its own sake. The goal is traffic to revenue, owned by one senior operator who reports against the numbers that matter and adjusts every week until the funnel pays.
Month one is a paid diagnostic. If it isn’t worth continuing, I’ll tell you, and you keep the plan. No long lock-in either way.
How to start
Hiring a fractional CMO for B2B SaaS should start with proof, not a pitch. Yaniv Goldenberg begins every engagement with a focused diagnostic: he reviews your funnel, your real numbers, and your market, then shows you exactly where revenue leaks and what the first 90 days would change. You see the plan and the math before you commit to anything, with no junior team waiting in the wings and no long lock-in. If a fractional CMO for B2B SaaS is not the right call for your stage, he will say so directly and point you to a better use of the budget. When it is the right call, you get one senior operator who owns the number from traffic to revenue, reports every week, and adjusts until the funnel pays. The work is hands-on, the reporting is honest, and the accountability sits with one person, not a rotating pod. That is the standard Yaniv holds on every account, and it is where the conversation starts. Reach out and we will look at your numbers together.

Frequently asked questions
What is a fractional CMO for B2B SaaS?
A fractional CMO for B2B SaaS is a senior marketing leader who owns your growth function on a part-time retainer instead of a full-time salary. They set strategy, direct the team, and carry revenue accountability, the same scope as a full-time CMO. The difference is cost and speed: you get senior leadership without a full-time hire.
When should a B2B SaaS company hire a fractional CMO?
Hire one when you have product-market fit and a budget, but no senior person owning growth. It is the right move when acquisition spend is climbing without a clear return on revenue. Seed to Series B companies get the most value, since a fractional CMO fixes the funnel fast without the cost or hiring delay of a full-time executive.
How much does a fractional CMO for SaaS cost?
A fractional CMO works on a monthly retainer for part-time senior leadership, which lands far below the cost of a full-time hire. A full-time CMO runs $250K+ per year plus equity and benefits; a fractional one costs a fraction of that because you pay for a set scope, not a full salary. The exact fee depends on scope and hours, set in advance.
Fractional CMO vs full-time CMO for a SaaS startup?
A full-time CMO is the right call once you can fund a full salary and keep a senior leader busy every week. Before that, a fractional CMO gives you the same strategy and execution for less money and starts in days, not months. For most Seed to Series B SaaS companies, fractional is the faster, lower-risk path to growth.
