Should You Hire a Fractional CMO, an Agency or the Growth System?
Buy the help that matches the gap. A fractional Chief Marketing Officer (CMO) fills an ownership gap: nobody is accountable for marketing. An agency fills an execution gap: the strategy is set and the hands are missing. The Constraint to Capability Growth System fills a capability or growth gap: a competent team is in place, marketing is busy, and the commercial number is not moving. Most mid-size Indian companies misdiagnose which gap they have.
This page is written by a firm that sells one of the three, and every other comparison you will read is written by a firm that sells one of the others. So we give you the test rather than the verdict. It is the test we use when a chief executive or CMO asks us, and it sends a fair share of them elsewhere.
For mid-size Indian companies with in-house marketing teams of 3 to 30 people.
The purchase should match the gap, not the symptom
The symptom is the same in all three cases: marketing is not delivering what the business needs. The cause differs, and so does the right buy. Find yourself in the last row; its column is the answer.
| Dimension | Fractional CMO | Agency | Growth System |
|---|---|---|---|
| What gap it fills | Ownership. There is no marketing leader in the seat, or the one in it is too junior to set direction and hold the budget. | Execution. The direction is set and the team cannot produce the volume or the craft the plan needs. | Capability and growth. A competent team exists, the activity is high, and the commercial number has stopped responding to it. |
| Who owns the outcome | The fractional CMO, part-time, for as long as the contract runs. Ownership leaves when they do. | The agency owns the deliverable. The client owns the result, and the gap between the two is where most disputes live. | Your team, from the first week. Bombay Breed owns the diagnosis and the method; the team owns the number. |
| How long | Open-ended. Typically six to eighteen months, renewed in blocks, and often longer than planned because the exit is never designed. | Retainer or project. Retainers run until someone decides to review them, which is usually later than it should be. | 90 days, fixed. Two of those days in person. It ends on a date agreed before it starts; a standing advisory retainer is available after, scoped separately. |
| What you are left with | A plan and a set of decisions. The judgement that made them is not transferred unless the contract says so, and it rarely does. | Campaigns, assets and reports. The capability to brief, judge and measure them stays where it was. | A written diagnosis, a 90-day pathway with named owners, and a team practised in the new way of briefing, deciding and measuring. |
| Incentive | To stay. Revenue is time-based, so the honest advice to hire a full-time leader and end the engagement competes with the invoice. | To spend. Revenue tracks media and production volume, so the advice to do less, or to fix the brief before the campaign, costs the agency money. | To finish. No media, and the fee is for the diagnosis and the capability, independent of any execution that follows, so the engagement is judged on whether the number moved. |
| When to choose it | The founder is the de facto CMO, or the marketing head left and the search will take two quarters. You need someone to hold the function now. | You know what to make and why. You lack the hands, the craft or the media buying scale to make it well. | You have the team and the agencies, the budget has gone up, and the result has not. You suspect the constraint is between the parts rather than inside any one of them. |

When a fractional CMO is the right buy
A fractional CMO is a senior marketing leader who takes the seat part-time, usually two or three days a week, and owns the function for the length of the contract. The model exists because mid-size companies often need CMO-level judgement before they can justify or attract a full-time CMO, and the gap between those two points can last years.
It is the right buy when nobody senior owns marketing. In India this usually looks like one of three situations. The founder is still approving every campaign at a scale where that is no longer a strength. The marketing head has left and the replacement search will run two quarters. Or the company has never had a marketing function and is building one from the first hire. In each case there is no one to advise, because there is no one in the seat, and an adviser without a decision-maker to advise produces documents.
It is the wrong buy when a competent marketing head is already in post. Placing a fractional CMO above or beside them creates two owners, and the incumbent either defers or leaves. If the team under a good leader is not converting activity into growth, the gap is capability, not ownership, and a second leader does not fix it.
When an agency is the right buy
An agency sells production and media at a scale and craft level that an in-house team of 3 to 30 cannot sustain across every channel. That is a real and durable need, and most mid-size Indian companies will keep two to five agencies on the roster whatever else they do.
It is the right buy when the team knows what it wants to make and why, and lacks the hands or the specialism to make it well. A clear brief, a thin output, and a measurement plan that already exists: that is an execution gap, and an agency closes it.
It is the wrong buy when the brief itself is the problem. An agency given a brief with no commercial question inside it will produce competent work that nobody remembers, then take the blame for a result it had no way of changing. Adding a third agency to fix the output of the first two is the most expensive misdiagnosis we see. The constraint sits in the brief, the approval and the measurement, and no agency is paid to fix those.
When the Growth System is the right buy
The third situation is the one the first two models are not built for. A marketing head is in post and competent. The team is busy. The agencies are delivering what they were briefed. The budget went up last year, and the commercial number did not. Nobody is failing, and the whole is still underperforming.
That is a capability gap, and it sits between the parts rather than inside any one of them: in the brief, in agencies working in parallel, in creative approved by taste, in AI tools that saved no hours, in measurement that reports activity. A fractional CMO sees some of this from the seat but is paid to run the function, not rebuild it. An agency sees it from outside and is not paid to say so.
The Constraint to Capability Growth System is built for this gap. Over 90 days it diagnoses where the marketing organisation is losing growth, budget and capacity, puts a rupee figure on each constraint, fixes the ones worth most on work already in flight, and leaves the method running inside the team. Two of the 90 days are in person.
It is the wrong buy when the seat is empty or the hands are missing. A diagnosis delivered to a team with no leader to act on it, or to a team that cannot produce the work the diagnosis calls for, is a document. We say so on the first call, and we point to the other two options when they are the answer. After the diagnosis a client can keep the firm on a standing advisory retainer or have it execute the fix alongside the team.
What changes when the company is Indian and mid-size
Most of the advice on this question is written for American companies with one agency of record and a professional CEO. The Indian mid-size company has a different shape.
Approval is founder-led. At 100 to 1,000 crore of revenue the founder or promoter family still approves marketing spend and often the creative. A fractional CMO who is not given authority over that approval is a consultant with a title, and should be bought and priced as one. The Growth System has to put the founder in the room for the decisions that matter, which is why two of its 90 days are in person.
Agencies come in multiples. A creative agency, a digital agency, a performance agency, a PR firm and a social media shop are normal for a team of ten. Nobody inside the company owns the whole, so the agencies optimise their own slice. That is why the capability gap is so often misread as an execution gap.
The team is small and the market is loud. A marketing team of this size competes in a market where attention is cheap to buy and hard to keep. That team cannot afford a leader who leaves with the judgement, an agency that is paid to spend more, or an adviser who stays past the point of usefulness. The right buy is the one that leaves the team more capable than it found them, whichever of the three that is.
How to tell which gap you have
Ask the question in each row of your own organisation before you take a vendor's call. The honest answer names the gap, and the gap names the buy.
Ask who decides what marketing does next quarter. If the honest answer is the founder, the CEO or an agency, the function has no owner.
Ask whether the team can describe the campaign it wants and simply cannot make it. If the brief is clear and the output is thin, the gap is hands.
Ask whether activity has risen while revenue has not. If the team is busy, the agencies are busy, and the number is flat, the gap is in how the parts work together.
What buyers ask before they choose
What is the difference between a fractional CMO and a marketing consultant?
A fractional CMO takes a seat in your organisation part-time and owns marketing decisions for the length of the contract. A marketing consultant advises the people who already hold those seats and does not take ownership of the function. The Constraint to Capability Growth System is a third form: it works inside the team for a fixed 90 days and leaves the capability with the team, not the consultant.
When should a mid-size Indian company hire a fractional CMO?
When there is no marketing leader in the seat and the business cannot wait for a full-time hire: a founder who is still the de facto CMO at 200 crore of revenue, a marketing head who has left with a two-quarter search ahead, or a first marketing function being built from nothing. The gap is ownership, and a fractional CMO is the correct buy.
What is the difference between a marketing agency and the Growth System?
An agency makes things: campaigns, content, media plans, creative. Its revenue rises with the volume it produces and the media it places. Bombay Breed diagnoses why the things being made are not moving the commercial number, and fixes the cause; it does not sell media. The two are not substitutes: a company usually needs its agencies, and a reason to brief them better.
How do I choose a marketing adviser for a mid-size company in India?
Start with the gap, not the vendor. Name whether the problem is ownership, execution or capability, because each has a different right answer. Then check the incentive: ask how the adviser earns, and whether that earning rises when you spend more or stay longer. Ask what you will hold at the end that you did not hold at the start. Ask for a fixed end date. And ask whether the adviser has worked inside Indian in-house teams of your size, with multiple agencies and founder-led approval, because that is the environment the advice has to survive.
Is the Constraint to Capability Growth System a fractional CMO service?
No. The Growth System does not take a seat and does not own the marketing function. It is a fixed 90-day engagement that assumes a marketing leader is already in post and makes that leader more effective, rather than replacing them.
Can a fractional CMO and the Growth System run at the same time?
Yes, and the combination is sound when the gaps are both present. A fractional CMO holds the seat and makes the decisions; the Growth System diagnoses where the team and its agencies are losing growth and builds the capability to fix it. The sequence matters: run the diagnosis early, so the fractional CMO inherits a clear picture of the constraints rather than discovering them over two quarters. The engagement ends on its date; the fractional CMO stays as long as the ownership gap does.
Not sure which gap you have? Bring the number.
Thirty minutes with Theresa Ronnie on the number that will not move tells you which of the three you need. If it is not the Growth System, we say so on the call, and you will have lost thirty minutes.
