Fractional CRO: part-time revenue leadership for B2B

Fractional CRO & Sparring Partner

I take on your revenue leadership on a part-time basis, one to three days a week, accountable for results. The scope is that of a Chief Revenue Officer: sales, marketing, customer success and partnerships under one direction. As a fractional revenue leader, I give you executive-committee seniority without the cost or commitment of a full-time hire.

The reality

When growth slows, it is rarely a matter of effort, more often of structure.

Past a certain stage, revenue can't be run on instinct: it needs a proven system, and someone to hold it. Here are the situations I see, and fix, most often:

A choppy pipeline

Revenue rests on two or three reps and a few good months you cannot predict.

Marketing and sales misaligned

Two teams, two goals, leads lost in between.

Growth rests on the founder

You still carry the closing and the strategic calls.

A full-time CRO isn't justifiable

You need the seniority, not (yet) the full-time C-level cost. That is exactly what a fractional CRO solves.

The most underestimated

Dashboards everywhere, data nobody has checked

Many leaders ask for dashboards without realising how broken their data is: poorly structured, poorly maintained, for lack of vision and rigour. Teams end up making calls on numbers nobody can check or cross-reference. Realigning the data is part of the job, to finally steer on reliable numbers.

Services

Two ways to work together

The fractional CRO owns revenue execution; the Sparring Partner sharpens the decision. We pick based on the intensity you need.

Embedded · strategic & hands-on

Fractional CRO

A fractional CRO is part-time revenue leadership: the Chief Revenue Officer role held on a fraction of the time, embedded in your leadership team, across the entire revenue chain rather than the sales force alone. I take ownership of revenue architecture, the alignment of sales, marketing, customer success and partnerships, and commercial performance, accountable for results.

The method

The ADAM method. Anything but magic.

Assess, De-risk, Align, Maximise. In that order.

Take away the flourish and what's left is the method: Assess, De-risk, Align, Maximise. A.D.A.M, like my first name. A system proven in the field, adapted to your context, not a one-size-fits-all trick.

A

Assess

Map the revenue system: pipeline, funnel, pricing, CRM, friction points. I identify what works, what doesn't, what's been tested and what never has, across people, process and tools, before touching anything.

D

De-risk

Stabilise the pipeline, protect existing revenue and stop the leaks. A reliable base before accelerating.

A

Align

Put marketing, sales and partnerships behind one goal. CRM, data, pricing, process and reporting brought back into coherence, to decide on reliable numbers.

M

Maximise

Open new levers (markets, outbound, team ramp-up) on healthy, measurable foundations.

My conviction

AI once the fundamentals are in place. Not before.

AI does not fix a badly designed revenue system: it amplifies its effects, good and bad. It can play at every level of the revenue machine: dashboards, data, prospecting, process, decision support. I guide my clients on that whole picture and put it to work where it truly creates value. On one condition: sound fundamentals first.

Who for

Three possible starting points

Nobody sees clearly the system they work in every day. My job is to surface those blind spots and fix them, wherever you're starting from.

01

You know where it's stuck

The revenue problem is identified. You just need someone to take it on and execute.

02

You sense it's stuck

Something's blocking the revenue machine, without you being able to pin it down yet.

03

You don't know it yet

Everything seems fine. But blind spots are already slowing growth, invisible when you're inside the engine.

FAQ

Frequently asked

What is a fractional CRO?

A fractional CRO is part-time revenue leadership, taking operational accountability for revenue 1 to 3 days a week rather than full-time. The scope is that of a Chief Revenue Officer: sales, marketing, customer success and partnerships, run together rather than in silos. The founder gets executive-committee seniority without the cost of a permanent hire.

What's the difference between a CRO and a VP of Sales?

A VP of Sales runs selling. A Chief Revenue Officer owns the whole of revenue: marketing, sales, customer success and partnerships, with the alignment of those functions as the first responsibility. A CRO is not a promoted VP of Sales: the role plays out at the junctions between functions, where most growth blockers sit.

What's the difference between a fractional CRO and outsourced sales leadership?

Outsourced sales leadership runs the sales force. A fractional CRO runs the full revenue chain, from marketing acquisition to retention via partnerships, from inside the leadership team and accountable for results. The distinction is scope: outsourcing sales leadership optimises one silo, a fractional CRO aligns the system.

How much does a fractional CRO cost?

A fractional CRO is billed as a monthly retainer, set by the number of days and the scope owned, not by time spent. The market benchmark: a full-time CRO in France typically represents a total cost above €200,000 a year, employer contributions included. The fractional format gives access to the same seniority for a fraction of that, with precise pricing set in direct conversation, based on your stakes.

Fractional CRO or hiring a permanent sales director?

Hiring a permanent sales director settles commercial execution, when the revenue model is stable. A fractional CRO makes sense when that model has to be redefined and sales, marketing and partnerships must be aligned under one direction — the most frequent case in a growth break. A hire commits several months of process and a high total cost, with a casting risk that is hard to correct.

What's the difference between a part-time CRO and an interim manager?

An interim manager fills a vacant role for a defined period, usually full-time, pending a permanent holder. A part-time CRO works a fraction of the time and over the long run, with a mandate to build the revenue architecture and the team that will run it — including, when the time comes, hiring their own successor. The difference is the mandate: to occupy, or to build then hand over.

From what company size does a fractional CRO make sense?

The format becomes relevant as soon as there is a revenue machine to structure: marketing, sales and partnership functions that have to work together, typically B2B scale-ups through to mid-market companies and groups, including LBO-backed ones with fund targets to hit. Below that, revenue steering still sits with the founder. I work mainly in B2B tech, SaaS and services, across 10 markets to date.

How long does a fractional CRO engagement last?

A fractional CRO engagement runs over time, generally several quarters — long enough to produce a measurable effect on acquisition, pipeline and retention. The frame, objectives and exit conditions are defined in the first conversation. The lighter Sparring Partner format works in recurring sessions at board level.

What is the ADAM method?

ADAM is the four-step methodology applied on every engagement: Assess the existing revenue architecture, De-risk what threatens the numbers short-term, Align sales, marketing and partnerships on a shared model, Maximise what already works.

Fractional CRO or Sparring Partner: how do I choose?

The Fractional CRO commits to results, alongside your teams. The Sparring Partner works at board level, to frame and challenge strategy. We pick based on the intensity you need.
