Managed marketing execution services for B2B firms without CMO are outsourced teams that run campaigns, content, paid media, SEO and reporting for a company that has no chief marketing officer to direct them. The service solves the work. It does not solve the missing decision-maker. A provider that only executes needs someone on your side who can set the ICP, approve the message and define a qualified lead. A provider that also supplies the leader replaces that person for as long as you pay. This guide gives a Decision Owner Sheet that shows who decides what, and a Missing-Seat Test for choosing among the three provider models.
Managed Marketing Execution Services for B2B Firms Without CMO: The Short Answer
- Fact: providers describe three models. Fractional CMO firms say their leader owns positioning, demand generation and pipeline reporting. GTM 8020 says an agency "runs campaigns" and "won't own your pipeline number". Kalungi describes a full-service model that bundles leadership and a 10-plus person team.
- Fact: CMO Syndicate separates a fractional CMO, who works part-time on an ongoing basis, from an interim CMO, who steps in full-time for a defined period to cover a gap.
- Inference: the first decision is not which provider but which seat is empty. If you have no one to direct a team, execution-only service leaves strategy with the founder or a sales leader by default.
- Opinion: buy execution only when a named person on your side can approve every item on the Decision Owner Sheet. Otherwise buy a model that supplies the leader, and set a date to review whether you still need one.
What the Main Pages for This Question Answer
The pages a buyer meets first are written by the providers. Each describes its own model well. None says what the buyer must still decide.
| Page | What it answers | What it leaves open | What it cites |
|---|---|---|---|
| Kalungi, Full Service | A bundled leadership and execution team compared with an agency and in-house hiring | What the client still approves | Its own customer quotes and cost comparison |
| GTM 8020, Fractional CMO for B2B | What a fractional CMO owns, how it differs from an agency and a full-time CMO, a typical monthly cost range | How the cost range was derived | Its own experience |
| CMO Syndicate, Fractional CMO for B2B Companies | Fractional versus interim leadership, and what a fractional CMO does | Who executes the campaigns | Its own services |
| 6sense, Navigating the New Age B2B Marketing Skills Gap (January 25, 2023) | Marketing-as-a-service as a long-term contract for execution capacity | Anything on selecting a leader | A savings figure from its own services business and published surveys |
| Directory and ranked-list pages (agency directories, vendor roundups) | Names of providers | Method, scope or what the buyer decides | Their own rankings |
Reading: every page defines a model and sells it. The gap for a company without a CMO is the hand-off: which decisions stay with you, and what the provider needs from you each week. This guide covers that gap. For adjacent scope questions, see demand generation consultant: what to hand over and what to keep and managed services content marketing.
Three Models, Defined
| Model | What you buy | Who sets strategy | Who runs the work | Source statement |
|---|---|---|---|---|
| Execution only | Campaigns, content, paid media, SEO, reporting | You | The provider | GTM 8020: an agency runs campaigns and will not own the pipeline number |
| Fractional leader plus execution | A part-time senior leader, plus an agency or contractors | The fractional leader | A separate team | CMO Syndicate: part-time, ongoing; owns positioning, demand generation and pipeline strategy |
| Bundled leadership and team | One provider supplies both | The provider | The provider | Kalungi: marketing leadership and a 10-plus person team, "fully accountable for growth" |
Fact: GTM 8020 gives a typical fractional CMO cost of $6,000 to $20,000 a month and says a full-time B2B CMO is right once marketing is a large permanent function. Kalungi's page lists in-house hiring as "$558k+ annual cost before taxes/benefits" and "8-12 hires". Both are provider figures on their own pages and are not audited here. Inference: the figures are in the providers' interest and use different bases, so neither is a benchmark. Ask each provider for the scope and the cost line by line.
The Decision Owner Sheet
The Decision Owner Sheet is one table you complete before signing. Each row is a decision a CMO would normally make. For each row, write who owns it: you, the provider, or both with a named approver.
| Decision | Owner (fill in) | What goes wrong if blank |
|---|---|---|
| Which accounts and roles are the ICP | Campaigns reach the wrong buyers | |
| Positioning and the claims the company will make | Each channel says something different | |
| What counts as a qualified lead, agreed with sales | Marketing reports leads that sales rejects | |
| Monthly budget and the channels it covers | Spend follows the provider's habits | |
| Who approves copy and campaigns, and how fast | Work waits and the retainer runs | |
| The numbers reported and their source | Results cannot be checked | |
| What happens to a lead after hand-off | Leads are collected and not called | |
| Who owns the website, CRM and ad accounts | Assets leave with the provider | |
| Review date for the arrangement | The contract continues by default |
Opinion: the row on ownership of accounts and data matters most when a relationship ends. Write down that the CRM, ad accounts and analytics are in your name.
The Missing-Seat Test
The Missing-Seat Test asks one question per row of the sheet: can a named person on our side give an answer, in the time the provider needs, without a meeting of the whole company?
- Every row passes. Execution only can work. You still need a weekly approver.
- ICP, positioning, qualified lead and budget rows fail. These are the strategy rows. Buy a model that supplies the leader: fractional plus execution, or bundled.
- Only approval and reporting rows fail. You need an internal coordinator more than a leader. A founder-assistant or operations hire may be enough.
- Most rows fail. The company is not ready to buy execution. Write the ICP and the lead definition first, with sales, and then retest.
Fact: 6sense describes marketing-as-a-service as a long-term contract for execution capacity from dedicated staff who function like internal employees. Inference: staff who function like employees still need someone to direct them.
One Rubric, Providers Compared
The questions are the same for every row, answered from each company's own pages. "Not described" means the page cited does not say.
| Provider or model | Leadership included | Execution included | Cost as published | Relationship |
|---|---|---|---|---|
| Kalungi, Full Service | "SaaS CMO" leadership | A 10-plus person team | Not described on the page cited | None |
| GTM 8020, fractional CMO | Fractional CMO | Not the main service; page contrasts it with an agency | $6,000 to $20,000 a month, typical | None |
| CMO Syndicate | Fractional or interim CMO | Not described on the page cited | Not described | None |
| 6sense, marketing-as-a-service (described in a blog post) | Not described | Dedicated staff on a long-term contract | A 52% labor cost saving, stated for its own clients | None |
| Lead Seeker | Not a marketing service | None; finds verified people at target accounts | Pricing on its page | Publishes this guide |
| Percepture | Intent data and signal mapping services | Delivered as a service | Not cited here | Led by the author |
| Pyra | Not a leadership service | Paid pilot of one workflow | Not described | Co-founded by the author |
Reading: the table covers different kinds of provider, so it is not a ranking. A buyer should read across a row to see what is missing, and ask the provider to supply the missing cell in writing.
From Marketing Execution to Sales Action
A marketing service produces activity. A sales team needs accounts, timing and a person. Whatever model you choose, ask for the same four things in the reporting.
- ICP. The accounts the activity reached, matched to your written ICP.
- Timing. The dated signal behind each hand-off, such as a visit, a download or a public event. The Percepture guide to using intent data to identify sales qualified leads covers where a signal sits next to a fit rule.
- Contact. The person to call. A form fill gives one. A company-level signal does not, and the best B2B contact database guide covers where to find one.
- Next action. What sales does, and by when. The marketing ops vs demand generation roles guide explains who owns the lead rules.
A signal is not proof that an account intends to buy. It is a reason for a person to look.
An Invented Example: Corvane Systems
The company and figures are invented to show the format.
Corvane Systems sells fleet-routing software to regional carriers. The founder runs sales and has no marketing leader. Filling in the Decision Owner Sheet, the founder can approve copy and budget, but cannot say what a qualified lead is without asking the sales lead, and the ICP is two sentences. That fails the strategy rows, so execution-only service is the wrong buy. Corvane chooses a fractional leader for the first quarter, with the first deliverable a written ICP and a lead definition agreed with sales. A separate team starts campaign work only after those are signed. The CRM and ad accounts stay in Corvane's name, and the review date is written into the agreement. Sales gets a weekly list of accounts with a dated signal and a named person.
Where Lead Seeker, Percepture and Pyra Fit
Lead Seeker is not a marketing agency and does not run campaigns. It fits after marketing has produced an account: Lead Compass reads your website, ICP and intent themes to surface opportunity picks, and a search returns verified people at the accounts you describe with the public signal behind each one. See how Lead Seeker works for the flow.
Percepture, where I am President, runs B2B intent data services for teams that want signal mapping set up with them. Pyra, which I co-founded, sells a paid pilot of one workflow; it would suit turning a weekly account list into research notes with a person approving anything sent. Opinion: none of the three replaces the owner of the Decision Owner Sheet, and a buyer should compare them with the other providers on the same rubric.
Limitations
- This is a documentation-based comparison, not a hands-on product test.
- Documents change. Vendor documentation and service requirements can change.
- Costs and savings figures are the providers' own. None was audited, and they use different bases.
- "Not described" is scoped to the page cited. It does not mean a provider lacks the service.
- The Decision Owner Sheet and the Missing-Seat Test are editorial methods, not standards, and the example company is invented.
- Customer testimonials on provider pages are outside this comparison. The provider selects them.
- Related-party rows rely on their own pages. Lead Seeker publishes this guide, and Percepture and Pyra are related companies.
- No client result is claimed.
Frequently Asked Questions
What is the difference between a fractional CMO and a managed marketing service?
On the providers' own descriptions, a fractional CMO is a part-time senior leader who owns strategy, positioning and pipeline reporting. A managed marketing service runs the work. Some providers sell both together. Check which of the two you are buying.
Can a B2B company run marketing without a CMO?
Yes, if someone on your side makes the strategy decisions on the Decision Owner Sheet and approves the work. If no one can, outsourced execution will wait for decisions that are not made.
Is a fractional CMO cheaper than a full-time CMO?
GTM 8020 states a typical fractional cost of $6,000 to $20,000 a month and says a full-time CMO is right once marketing is a large permanent function. That figure is the provider's own. Ask any provider for the cost in writing.
What should marketing hand to sales?
An account that matches the ICP, a dated reason, a named person and a stated next action. A count of leads alone does not say any of these.
How This Guide Was Built
The Decision Owner Sheet, the Missing-Seat Test and the example are this guide's own editorial methods, not provider features or benchmarks. Each provider is read against the same questions, and a cell is filled only from a named page or marked as not described. Provider pages are the primary source for what each says it sells. The labels Fact, Inference and Opinion mark what a source states, what follows from it and what the author recommends. Nothing here is a hands-on test of a service or a client result. This is an October 27, 2026 snapshot.
