Who owns the number

Fractional CGO vs Growth Agency

Led growth at cnvrg.io before its acquisition by Intel.

Compare a growth agency and a direct operator against the actual decisions, personal implementation, specialist capacity, evidence, costs and continuity needed. I personally lead and implement the agreed work; the provider label alone does not define its scope.

The real comparison

Accountability versus capacity, not good versus bad

The comparison is the actual work order and named delivery people. Ask each option who develops strategy, implements campaigns and journeys, owns approvals and measures the relevant commercial outcomes.

Ask each proposal who can make the relevant decisions, who personally investigates and implements, what client approvals remain and how the evidence is reviewed. At Elementor I led acquisition during company growth from $200K to $20M ARR. That experience informs the work without proving an agency cannot cross functions or that I owned every corporate decision. Compare mandates in chief growth officer vs VP of growth.

Who owns the number

Four places accountability splits a CGO from an agency

01

Who owns the number

Review the actual responsibilities for commercial decisions, personal implementation and source-grounded measurement. I personally lead and implement the selected work and coordinate shared dependencies with client owners. An agency’s accountability depends on its contract and team, not its label.

02

Strategy plus execution, not one or the other

I combine strategy with my personal campaign, conversion, lifecycle and measurement delivery within scope. Compare the agency’s actual leadership and implementation as well. Name approvals and review owners so the work and commercial decisions connect.

03

Incentives pointed at your revenue

Inspect the actual fee structure, budget authority, reporting definitions and incentives of each proposal. A retainer alone does not prove misalignment or activity-only work. My personal delivery and review responsibilities are defined around the agreed business decision.

04

Capability that stays after I leave

Compare account ownership, editable assets, documented decisions, tests, training and handover in the actual contract. I personally build and document agreed work and test its transfer to the receiving owner. Continued operation, support and maintenance follow the scope; a category does not determine what remains.

How the engagement runs

What a fractional CGO does that an agency will not

Weeks 1-3

Find where revenue actually leaks

Map the full funnel, instrument real attribution, name the constraint. An agency starts from the channel it sells. I start from your number and work backward to the bottleneck, which is often nowhere near the channel an agency would have pitched you.

Month 1-2

Decide build vs rent, channel by channel

Some channels genuinely belong with a specialist agency and I will tell you which and brief them. Others belong in-house. The point of the role is making that call deliberately instead of defaulting to outsourcing everything, then owning the result either way.

Ongoing

Stay accountable to one number

One agreed metric, usually net new revenue or net revenue retention, reported against outcomes. Time commitment, duration and handoff are agreed for the engagement.

When each one wins

Why this is a sequencing decision, not a versus

A focused Google Ads, content or other channel task can fit my personal implementation, an agency or another specialist. Compare the actual skills, relevant evidence, capacity and costs. A senior growth title does not prevent me from personally delivering channel work.

Investigate whether the constraint is within a channel, a journey, a product or the coordination between owners.

The constraint can sit in a channel, customer journey, product or handoff. A fractional CMO or CGO can personally lead and implement agreed cross-functional work when decision rights and owners are explicit. The CMO as a service model explains those scope choices; an agency’s capabilities likewise follow its actual proposal.

Choose the sequence from the actual decision, evidence and capacity. I can personally diagnose and implement the selected work while coordinating agencies or specialists where needed. A CGO-first sequence is not a prerequisite for every useful channel or growth project.

Before expanding spend, agree the question, eligible outcome, budget limits and implementation owners. Existing leaders or specialists may already supply that judgement. Choose additional leadership or delivery from a named gap rather than assume agency-first work necessarily wastes money.

FAQ

Fractional CGO vs growth agency FAQ

How is hiring a fractional CGO different from hiring a growth agency?
Compare the actual leadership, personal implementation, specialist capacity, commercial measures and continuity in the scope. I personally deliver the work we agree; an agency’s responsibilities depend on its actual proposal rather than a universal channel-only model.
Is a fractional CGO more expensive than a growth agency?
Compare actual full costs, retained accounts and assets, documentation, support and handover terms. An agency can leave useful capability and a direct operator can require maintenance or support; the contract and implementation determine the result.
Can I use both a fractional CGO and a growth agency?
Yes. We name the leadership, personal implementation, specialist production, approvals and review responsibilities for the actual work. The appropriate sequence follows the evidence and dependencies rather than a universal operator-first rule.
When should I hire a growth agency instead of a fractional CGO?
Choose the proposal and people that fit the actual channel or broader growth work: relevant skills, capacity, evidence, decision rights, full cost and continuity. I can personally deliver focused channel implementation or cross-functional work as agreed.
Is a fractional CGO engagement right for a company before product-market fit?

Fractional CGO work suits companies that already have product market fit and real traction, and that want to grow revenue rather than just traffic. Before product market fit, we first check whether a scoped engagement makes sense at all. Growth work compounds on a product that works; it cannot manufacture demand for a broken one.

Does a fractional CGO only set strategy, or also run the work?

I personally lead strategy and implement the agreed campaigns, journeys, systems and measurement. We coordinate dependencies with the responsible client and specialist owners. Compare an agency’s actual strategy and build responsibilities rather than assume its work stops at a channel boundary.

What should I bring to a scoping call, and how fast do you reply?

Tell me what has stalled, which channels you already run, and what an agency has or has not moved. I will tell you whether you need an accountable owner, a channel specialist, or both in sequence, and what the first 30 days look like. I reply within 1 business day.
