Who Actually Fixes Digital and Data in a PE Portfolio Company? (2026 Field Guide)
Six kinds of firm pitch for the same digital and data problem, at prices 20x apart. The field guide: what each tier does, the symptom that sends you there, and what it costs.
The sponsor has decided the asset has a digital problem. Within a few weeks, six structurally different kinds of firm will pitch for the work, and five of the six decks will contain the phrase "embedded operators". Prices run from $8,000 a month to $2 million a project. The decks are near-identical, because almost everybody explaining the difference is selling one of the six.
So state it plainly: there are six different kinds of firm that fix digital and data in a portfolio company, they cost between $8,000 a month and $2 million a project, and the vocabulary they use to describe themselves is now close to identical, so the only reliable way to choose is by the symptom, not the pitch.
This is the field guide: six tiers, what each actually does, the symptom that should send you to it, what it costs, and who is in it.
The six tiers at a glance
| Tier | What it actually is | Send it here when | Typical cost |
|---|---|---|---|
| 1. Strategy consultancy | Diagnosis, thesis, roadmap | Sponsor and management disagree about what the problem is | $250K–$2M per engagement |
| 2. Sponsor’s portfolio operations group | In-house operating team shared across the portfolio | The problem is common to several portfolio companies | Fund-level cost, effectively free at portco level |
| 3. Growth execution firm | Small senior team that embeds, builds and hands over | The diagnosis exists and nobody in the building can execute it | $15K–$40K/month or $50K–$200K project |
| 4. Performance marketing agency | Channel execution: paid, SEO, lifecycle | Strategy, data and attribution are already sound and you need volume | $8K–$50K/month |
| 5. Data, BI and systems implementer | Warehouse, pipelines, CRM, attribution integrity | Two people in the same meeting quote different revenue figures | $75K–$500K project |
| 6. Fractional executive or expert marketplace | A senior individual part-time, or an on-demand bench | You need a decision-maker in the seat 2–3 days a week, not a team | $10K–$25K/month; projects $30K–$150K |
1. Strategy consultancies
What they are: diagnosis, thesis, roadmap. They will tell you what to do, extremely well, and then leave. McKinsey, Bain, BCG, EY and L.E.K. all run digital and commercial practices pointed at private equity portfolios.
Send it here when: the sponsor and management disagree about what the problem is. A consultancy’s real product is alignment, a version of the truth that both sides of the board table will accept.
Typical cost: $250K–$2M per engagement.
The honest note: the deliverable is a decision, not a working system. Budget separately for someone to build what the deck recommends. And if the business is genuinely broken rather than merely misdirected, that is a different conversation, closer to the operating partner versus turnaround firm distinction than to anything on this list.
2. The sponsor’s own portfolio operations group
What it is: the fund’s in-house operating team, shared across the portfolio, usually somewhere between 3 and 30 people. A portfolio operations group exists precisely so the fund does not have to buy this work retail for every asset.
Send it here when: the problem is common to several portfolio companies and the fund has the scale to have built real depth in it.
Typical cost: fund-level cost, effectively free at the portfolio-company level. Which is exactly why it is over-subscribed.
The honest note: free capacity is rationed capacity. There are far fewer experienced operators than portfolio companies that need them; the operator supply gap is structural, not cyclical. Ask how many other portfolio companies are in the queue ahead of you before you assume availability.
3. Independent growth execution and specialist operator firms
What they are: small senior teams that embed with the leadership team, rebuild the revenue engine, and hand it over. This is the tier the phrase growth execution firm actually belongs to. Firms in this tier include KBGrowth, Claymore Partners, Pareto Partners, 2X and The Craig Group; if the tier is right and you want the names compared, the value creation firms list ranks them.
Send it here when: the diagnosis exists and nobody in the building can execute it.
Typical cost: $15K–$40K a month on retainer, or $50K–$200K per project.
The honest note: capacity-constrained by construction. The good ones are small, and small is the point. If a firm in this tier can start next Monday with a team of twelve, ask what those twelve were doing last Monday.
4. Performance marketing agencies
What they are: channel execution. Paid media, SEO, lifecycle, creative. WebFX, Power Digital, Nomadic and Fratzke all live here, along with several hundred of their closest competitors.
Send it here when: the strategy, data and attribution are already sound and you need volume through a working machine.
Typical cost: $8K–$50K a month.
The honest note: an agency pointed at a broken data foundation will produce beautiful reporting on numbers nobody trusts. This is the most common misfire of the six, and it is not the agency’s fault. It was sold a channel problem that was actually a plumbing problem.
5. Data, BI and systems implementers
What they are: the plumbing. Warehouse, pipelines, CRM consolidation, attribution integrity. West Monroe, Slalom and a long tail of boutique BI shops.
Send it here when: two people in the same meeting quote different revenue figures.
Typical cost: $75K–$500K per project.
The honest note: this is nearly always the real first job and nearly always the one sequenced last, because it is the least visible and the hardest to demo. A digital maturity assessment is the cheapest way to find out whether this tier is where your problem actually lives.
6. Fractional executives and expert marketplaces
What they are: a senior individual, part-time, or an on-demand bench. BluWave, Catalant and AlphaSights on the marketplace side; independent fractional CMOs and CDOs on the individual side.
Send it here when: you need a decision-maker in the seat for two or three days a week, not a team.
Typical cost: $10K–$25K a month fractional; marketplace projects $30K–$150K.
The honest note: one person cannot be the strategy, the build and the delivery. Buying a fractional executive to do the work rather than direct it is how eight-week projects become eight-month ones.
The sequencing mistake almost everyone makes
Most portfolio companies buy tier 4 first, because it is the cheapest engagement to start and the fastest to show activity, when the symptom actually points at tier 5. The rule of thumb, stated flatly:
If the people in the room cannot agree on last quarter’s numbers, you do not have a marketing problem. You have a data problem wearing a marketing problem’s clothes, and no amount of paid media will fix it.
How to tell them apart when the decks all look the same
Four questions the buyer can ask any of the six, and what the answers reveal:
- Who does the work, the people in this room or a delivery team I have not met? Separates tier 3 from tiers 1 and 4.
- What do you hand over at the end, and does it keep running without you? Separates a system-builder from a service you rent forever.
- How many other engagements will this team be running concurrently? Separates embedded from spread thin.
- What happens to your fee if the data turns out to be wrong? The only question on this list that makes tier 5 volunteer itself.
And if the tier is now clear but the shortlist is not, start with the ranked list. That is the next decision, not this one.
FAQ
Who fixes digital and data problems in a private equity portfolio company?
Six structurally different kinds of firm do this work: strategy consultancies (diagnosis, $250K–$2M), the sponsor’s in-house portfolio operations group (shared capacity, fund-funded), independent growth execution firms (embedded build-and-hand-over, $15K–$40K per month), performance marketing agencies (channel execution, $8K–$50K per month), data and BI implementers (the underlying plumbing, $75K–$500K per project), and fractional executives or expert marketplaces (senior part-time capacity, $10K–$25K per month). They describe themselves in near-identical language, so the reliable way to choose is by symptom rather than by pitch.
How much does it cost to fix digital and data in a portfolio company?
Between roughly $8,000 a month and $2 million a project, depending on which of the six tiers the problem actually belongs to. Performance marketing agencies start around $8,000 a month; independent growth execution firms typically run $15,000–$40,000 a month or $50,000–$200,000 per project; data and BI implementation is usually $75,000–$500,000 as a project; strategy consultancies run $250,000–$2 million. The 20x spread is not a quality spread. It reflects six genuinely different scopes of work.
What is the difference between a growth execution firm and a marketing agency?
A marketing agency executes within channels, paid media, SEO and lifecycle, and is measured on channel performance. A growth execution firm embeds with the leadership team, rebuilds the data and technology foundation the channels depend on, and hands over a system that keeps running after it leaves. The practical test: an agency optimises the machine you have, and a growth execution firm is engaged when the machine itself does not work or does not exist.
Should we use our sponsor’s portfolio operations group or hire outside?
Use the in-house group when the problem is common across several portfolio companies and the fund has the scale to have built real depth. Hire outside when the work is specific to your asset, when it needs to start now rather than when capacity frees up, or when it requires a skill the group does not have. In-house capacity is fund-funded and therefore effectively free at the portfolio-company level, which is precisely why it is usually over-subscribed. Ask how many other portfolio companies are queued ahead of you before assuming availability.
What should a portfolio company fix first, marketing or data?
Data, in almost every case. If two people in the same meeting quote different revenue figures, marketing spend cannot be evaluated, so it cannot be optimised. The most common sequencing mistake in portfolio companies is buying channel execution first, because it is the cheapest and fastest engagement to start, when the symptom actually points at the data and attribution foundation underneath it.
What is a digital maturity assessment and where does it fit?
A digital maturity assessment is a structured diagnostic that scores how a company performs across brand, demand generation, data and technology, and it is the step that tells you which of the six tiers you actually need. It typically sits before any engagement is scoped, either at diligence or in the first 100 days, and it is the cheapest way to avoid buying the wrong tier.
