When to Fire Your Marketing Agency: A Board-Ready Checklist for PE Portfolio Companies

You inherit the agency with the deal. The decks are polished. The dashboards glow. CAC looks "healthy" until finance loads fees, production, and refunds, and the number softens into something you would not put in an IC memo. That is the moment most operating partners start asking when to fire marketing agency PE holdings actually need to exit, and when a fix is cheaper than a swap.

I sit in that seat. The question is rarely "do we hate this vendor." It is whether the retainer still serves unit economics, attribution integrity, account ownership, creative velocity, and board reporting inside a hold period. This is a keep / fix / replace checklist for portfolio companies, not a ranking of agencies. Use it even if you never hire Impaxium.

Why PE agencies fail differently than founder-era retainers

Founder-era agencies optimize for the founder's taste, brand comfort, and monthly narrative. PE agencies (or the same shops under a new sponsor) fail on a different scoreboard.

Board cadence compresses storytelling. A monthly agency deck can hide soft CAC for a year. A quarterly board pack with a partner who owns the model will not. If the agency cannot speak spend, payback, and pipeline without translating into ROAS poetry, the relationship is already misaligned with the hold.

Hold periods punish slow remediation. You do not have five years to "build the brand" while CAC drifts. You have a finite window to install measurement, own the accounts, and show contribution that survives diligence on exit. An agency that needs nine months to "get up to speed" after every strategy call is burning hold time, not learning.

Unit economics beat vanity efficiency. Platform ROAS on soft conversions, branded search treated as growth, and MER that ignores fees are founder-deck habits. Under PE, fully loaded CAC, contribution payback, and CRM-reconciled pipeline are the language. Agencies that refuse that language are not "creative partners." They are reporting risk.

This gap sits inside a larger staffing pattern we covered in why PE firms staff every function except growth. Ops and finance get shared standards. Growth gets inherited vendors nobody on the fund side is paid to challenge. The checklist below is how you challenge them without turning every board into a vendor roast.

Board-ready keep / fix / replace checklist

Score the agency on the signals the board already understands. Do not score "chemistry," "brand awards," or "they know our category" as primary criteria. Those can matter after economics and control clear the bar.

When you evaluate marketing agency performance for a PortCo, force a three-bucket call. "We will give them one more quarter" without a written fix plan is how soft CAC becomes a year of lost hold time.

Kill signals in detail (when to fire, not just frown)

CAC is flat or rising after you load the real costs

Ask for fully loaded CAC: media, agency fees, attributable production, lead buys, affiliates that hit the growth P&L. Decide with finance whether sales commissions sit in CAC or cost of sales, then apply the same rule every month. If "efficient" CAC only works when fees and production are excluded, you do not have efficiency. You have a presentation choice.

Flat CAC with rising spend is not stability. It is a machine that needs more fuel to stand still. Rising CAC after creative "refreshes" and budget increases is a replace signal unless the agency can show a test calendar, a funnel leak diagnosis, and a CRM reconciliation that proves the problem is not fake conversions. Soft conversions (page views, engaged sessions, form starts) as the primary optimization event are a kill signal when the board is asked to believe ROAS.

No account ownership (you cannot take the keys)

If the agency holds Google Ads admin, Meta Business Manager ownership, the analytics property, the tag manager, or the ESP under their corporate entity, you do not have a vendor. You have a hostage situation with nice slides. PortCo or fund must hold admin. Agency can have operator access. Anything else is an exit risk on day one of a swap, and a diligence risk on exit.

Shared pixels on founder-personal Business Managers, login spreadsheets in a PM's Notion, and "we will transfer when the contract ends" are the same problem in different clothes. Ownership is a keep / replace binary. Fix only if transfer completes inside a short, dated window with written confirmation.

Measurement refusal or attribution theater

Agencies that will not reconcile platform conversions to CRM pipeline, that change attribution models to rescue the deck, or that treat Performance Max and Advantage+ claims as mutually exclusive ledgers are failing a marketing agency audit private equity operators should run before any fire decision. We wrote the board language in marketing attribution the board will actually trust. If the agency will not lock sourced vs influenced, freeze a window for the hold, and show platform-vs-CRM gaps, you are funding fiction.

Refusal shows up as: no admin for the fund's analyst, no export of change history, soft events as primary conversions, branded search credited as net-new growth without a non-brand frame, and quarterly model swaps that "improve" sourced share with no operational change. That is replace territory, not a workshop.

Creative velocity stalls

Auction prices rise. Fatigue is real. An agency that ships one concept family per quarter, recycles the same three hooks, and treats "brand guidelines" as a reason not to test is burning media against stale assets. Ask for a dated test calendar: hypotheses, variants, kill criteria, and learning logged to the board pack. No calendar after two asks is a kill signal.

Velocity is not chaos. It is a cadence the OP can inspect. If every new ad requires a three-week brand committee and the agency never pushes back with a PE-relevant urgency frame, you have a process problem dressed as craft.

Lead quality sales will not work

Volume without close rate is a tax. When sales leadership says the leads are junk, do not settle the argument in Slack. Pull stage conversion, speed-to-lead, ICP fit, and refund or churn where relevant. If media optimizes to form-fills sales cannot close, and the agency answers with more top-of-funnel budget, you are watching a replace pattern. Fix is possible when the agency accepts harder conversion events, tighter audiences, and joint SLA with sales. Replace when they defend volume as success.

Reporting language that cannot survive the board

Listen for dialect. "Engagement," "share of voice," "brand lift," and "ROAS" without payback can exist in an appendix. They cannot be the primary board story for a growth thesis PortCo. The pack should lead with fully loaded spend, CAC, payback, MER, sourced and influenced pipeline under locked definitions, and three actions with owners. If the agency cannot or will not write that pack, they are not board-ready. Related context for the missing growth seat: PE firms staff every function except growth.

Audit before you fire (and before you replace)

Firing without an audit is how you swap one vanity reporter for another. Run a short, fund-side marketing agency audit private equity operating partners can defend: tracking integrity, spend quality, funnel conversion, lifecycle and owned demand, then vendor fit and account ownership. The order and scorecard live in the portfolio marketing audit for private equity. Pair it with attribution standards so the next vendor inherits definitions instead of inventing them.

Audit outcomes that change the fire decision:

• Red tracking, cooperative agency: often FIX with a dated remediation, not an immediate replace.
• Green tracking, red economics and ownership: REPLACE. The numbers are honest enough to prove the retainer is not working.
• Red tracking and ownership lock-in: REPLACE with exit protocol in parallel. Do not "wait for Q4 learnings" while you lack keys.
• Media problem vs leadership problem: a specialist paid shop cannot replace a missing executive buyer. Sometimes you keep or swap media and install fractional CMO coverage so someone owns the brief.

If paid media is the bottleneck after the audit, use shortlists as input, not as a substitute for the checklist: best paid media agencies for private equity and best growth marketing agencies for private equity. The audit decides whether you need full-stack growth, specialist auctions, or a fund-side standard first.

60-day exit protocol when you replace a marketing agency

When the call is replace, move like an operator, not like a breakup email. The goal is continuity of spend and truth of measurement, not a dramatic cutoff that orphans pixels.

1. Days 1-7: Lock access and inventory. Confirm PortCo or fund admin on Google Ads, Meta Business Manager, analytics, tag manager, ESP, call tracking, and any CDP. Export change history, audiences, negatives, conversion actions, and creative archives. Document every pixel and CAPI endpoint. If the agency resists, that confirms the replace call. Escalate contractually.
2. Days 8-21: Freeze definitions and handoff brief. Write the CAC inclusions, sourced vs influenced rules, attribution window, and board pack template the next team must inherit. Pull the last 90 days of spend, CAC, stage conversion, and creative winners. Name the interim owner (internal lead, fractional CMO, or PE advisory) who accepts the keys.
3. Days 22-45: Parallel run or clean cut with cover. Prefer a short parallel where the new operator has admin and the old agency is read-only or limited. Migrate audiences and conversion actions carefully. Do not let the outgoing team "optimize" into soft events on the way out. Keep brand search and proven non-brand structures stable unless the audit showed waste.
4. Days 46-60: Contract end, knowledge closeout, board note. Final asset transfer, revoke access, close open POs, and file a one-page board note: why replaced, what was audited, what definitions are locked, who owns the next 90 days. That note stops the next partner from asking why you "changed agencies again" without a paper trail.

Never start a replacement search while the old agency still owns the logins. Never sign a new retainer that rebuilds vanity ROAS without inheriting the portfolio scorecard. The exit protocol is part of how you replace marketing agency portfolio company relationships without torching the hold narrative.

What good replacement looks like

Good replacement is not "a hotter shop." It is a vendor (or internal plus specialist mix) that clears the same checklist you just used to fire.

• Economics first: reports fully loaded CAC, payback, and MER in the fund's definitions from week one.
• Ownership first: PortCo or fund holds admin; agency operates under it.
• Attribution integrity: CRM reconciliation, locked sourced vs influenced, no silent model shopping.
• Creative system: dated test calendar, kill criteria, and learning in the board pack.
• Senior time on the work: named lead with authority, not a revolving junior bench sold as a senior roster.
• Fit to the gap: specialist paid media when auctions are the bottleneck; full-stack growth when channel mix and funnel are the bottleneck; fractional CMO or PE advisory when the gap is executive ownership of the brief.

Impaxium can run the audit, sit in the PE advisory seat for the keep / fix / replace call, and cover fractional CMO when the PortCo needs a buyer for the next agency. That is support for the decision. It is not a claim that every replace path ends with Impaxium as the media agency of record. Soft next steps live at PE advisory, fractional CMO, and contact.

Frequently asked questions

When should a PE portfolio company fire its marketing agency?

A PE portfolio company should fire its marketing agency when fully loaded CAC is flat or rising without a credible remediation, when the agency refuses CRM-reconciled measurement or board-grade reporting, when the agency owns the ad and analytics accounts, or when creative velocity and lead quality stay broken after a dated fix plan. Pretty dashboards alone are not a keep signal.

How do you evaluate marketing agency performance for private equity?

You evaluate marketing agency performance for private equity against unit economics (fully loaded CAC, payback, MER), attribution integrity, account ownership, creative test cadence, lead-to-close quality, and whether the board pack uses locked definitions. Chemistry and category "experience" are secondary after those clear.

What is a marketing agency audit for private equity portfolio companies?

A marketing agency audit for private equity portfolio companies is a fund-side review of tracking integrity, spend quality, funnel conversion, lifecycle yield, and vendor fit or ownership, scored so operating partners can make a keep / fix / replace call before swapping retainers. The practical order is documented in Impaxium's portfolio marketing audit guide.

Should you audit before you replace a marketing agency at a PortCo?

Yes. You should audit before you replace a marketing agency at a PortCo so you know whether the failure is measurement, media, funnel, lifecycle, or leadership, and so the next vendor inherits locked CAC and attribution definitions instead of rebuilding vanity ROAS.

What belongs in a 60-day agency exit protocol?

A 60-day agency exit protocol should include admin lock and asset inventory, frozen CAC and attribution definitions, a handoff brief, parallel-run or controlled cutover, revocation of access, and a one-page board note on why the replace happened and who owns the next 90 days.

Can you fix an agency instead of firing it?

Yes. You can fix an agency instead of firing it when economics are directionally sound, the team cooperates on ownership transfer and measurement remediation, and a written 60-90 day plan has owners and kill criteria. Fix without a dated plan is delay.

Who should own ad accounts after you replace a marketing agency?

The PortCo or the fund should own ad accounts, analytics, pixels, and the ESP after you replace a marketing agency. The new agency should operate under that ownership. Agency-owned accounts recreate the same exit and diligence risk.

How does Impaxium help when PE firms need to replace a marketing agency?

Impaxium helps when PE firms need to replace a marketing agency by running the portfolio audit, advising the keep / fix / replace call from the fund side, locking board reporting standards, and providing fractional CMO coverage so someone owns the brief during handoff. Soft paths start at PE advisory and contact.

Make the call before soft CAC becomes the hold story

Inherited agencies fail in PE for predictable reasons: vanity metrics, soft CAC, weak ownership, stalled creative, and reporting that cannot survive a partner who owns the model. The fix is not another emotional breakup. It is a board-ready checklist, an audit before you fire, and a 60-day exit protocol when replace is the honest answer.

Use keep / fix / replace on purpose. Lock CAC and attribution before you shop replacements. Take the keys before you sign the next retainer. When you need a fund-side seat on the audit or the handoff, start at PE advisory, bring in fractional CMO coverage if the PortCo lacks an executive buyer, or contact us for a single-company diagnostic. Typical response is one business day. The next board does not need another glowing dashboard. It needs a decision you can defend.
