B2B marketing companies, compared by type, scope, and cost

The five types of B2B marketing companies

Every firm on a typical shortlist belongs to one of five categories. The category, not the pitch, predicts what you will actually receive.

Read the table by constraint. If your problem is that nobody owns the whole picture, you are shopping in row one or two. If your problem is that one channel is underperforming while the rest work, you are shopping in row three.

How much B2B marketing companies charge, and why the ranges differ so much

Price in this market is a function of scope and seniority, not of results. A $4K/mo engagement and a $30K/mo engagement are usually both honest, and they are buying different things: capacity in the first case, an owned system in the second.

Below roughly $4K/mo you are generally buying one person's part-time capacity with agency overhead attached. That can be the right purchase when you already own strategy and need execution volume. It is the wrong purchase when nobody internally owns the plan.

The signal worth weighting is whether the number is published or invented per prospect. A firm that prices from your funding announcement is telling you something about how it will handle scope later.

• Retainer buys the team and the system, not a fixed unit of output
• Media spend, licenses, and third-party fees sit outside the retainer at every credible firm
• One-time implementation or build fees are normal, and should be stated up front
• Percentage-of-spend paid models reward bigger budgets, not better performance

A shortlisting rubric you can copy

Score every candidate on the same five dimensions and give each a one to five. The exercise is less about the total than about seeing which candidate you cannot score, because that is usually the one selling a deck.

Do this before the second call. Anything you cannot answer from public information plus one conversation is a scope you will be negotiating for six months.

• Constraint fit: does this firm fix the specific thing that is stalling us
• Named ownership: who does the work after signature, by name and role
• First 90 days: a specific deliverable list with dates, not a phase diagram
• Measurement: does reporting end at pipeline or at impressions and activity
• Scope honesty: is there a written list of what they will not do

Questions that separate operators from proposal factories

Every firm answers the capability questions well, because those are rehearsed. The useful questions are the ones with a cost to answering honestly.

• What would you cut from our current program first, and what evidence would trigger it
• Describe an engagement that failed and what you changed afterward
• Which of our competitors would you refuse to work with, and why
• If leading indicators are flat at day 90, what specifically happens
• What is out of scope, in writing, before we sign

Where Momentence fits, and where it does not

We are the second row of the table: a search-and-AI-search-led integrated firm for B2B and B2C software companies. We own the website, SEO, AEO, GEO, content, and paid under one strategist, on one plan, with one measurement layer. That is the build for a company whose constraint is fragmentation or a site that cannot support content.

We are the wrong choice in three clear cases. If you need positioning and category work, a product marketing consultancy will do it better than we will. If you need outbound conversations this quarter, an ABM or outbound firm is the right call, and we refer software companies to Managed Outbound for that. If one channel is your only gap and you own the rest, a specialist in that channel is cheaper and faster than hiring us.

We have an obvious bias here. The table above is written the way each type's best clients describe them, and the three cases where we are wrong are the ones we actually turn down.

Agency, in-house, or both

The comparison most teams skip is against building internally. A senior generalist marketer plus contractors lands in a similar total cost to a mid-tier retainer, with more control and slower ramp. It wins when you have someone senior to hire and manage.

Hiring an outside firm wins when you need six specialisms at once and cannot justify six hires, or when the work front-loads and then drops to maintenance, which is exactly the shape of a website rebuild plus an organic and AI search program.

The hybrid that works most often is one internal owner who holds strategy and the customer relationship, with an outside firm running execution across channels. The hybrid that fails is an outside firm hired to be the strategy with nobody internal accountable for it.

How to run the process without burning a quarter

Write your constraint in one sentence. Pick the row of the table that fixes it. Talk to three companies inside that row rather than one from each row, so the proposals are comparable. Score on the rubric, not on the deck.

Then choose on the out-of-scope list rather than the capability list, because the out-of-scope list is what you will be managing around every month.

Pricing, in public

Every engagement is published pricing on a 6-month minimum: Ignite at $7.5K/mo plus a one-time $4,500 implementation fee, Momentum at $15K/mo, Dominate at $30K/mo, and Custom starting at $50K/mo for a fractional multidisciplinary pod. You will know what this costs before you ever get on a call.
