Top B2B marketing companies, compared on evidence

Agencies with a verified published price

How to build a shortlist of B2B agencies that holds up

1. Decide which job you are buying first. Demand generation, brand and positioning, account based programmes, technical search and content, and revenue operations are five different disciplines that share a label. Write down which one is your binding constraint this year, because a firm excellent at one is often mediocre at another, and a shortlist assembled before that decision compares suppliers on nothing.
2. Filter on published evidence, not on rankings. Use published starting prices and disclosed minimums to remove firms whose floor is above your ceiling before anyone spends time on a call. Absence of published pricing is not a mark against quality, but it does mean the qualifying conversation happens live, so keep those candidates in a separate group and handle them together.
3. Send one identical written scope to everyone. Name the deliverables, the cadence, the geographies and the reporting you expect, then ask every candidate to price that exact scope. This single step does more to make proposals comparable than any amount of research, and the candidates who push back on the scope usually tell you something useful about it in the process.
4. Interrogate the team, the term and the exit. Ask who is assigned, how many other accounts they hold, what is subcontracted, what the minimum term and notice period are, and what happens to your website, content, ad accounts and data if you leave. Get the last one in the contract rather than in an email, because it is the term that costs the most when it is missing.

What we record about each firm

Our index records what an agency states publicly on its own site, with the date checked, rather than what a directory badge or an award page asserts. That means published starting prices where they exist, disclosed minimum engagements and minimum terms, named clients, and the service lines the firm itself claims. Where a firm publishes nothing on price, we record the absence rather than filling the gap with an estimate, because an invented figure is worse than a blank space.

The pattern in business to business services is consistent. Firms selling productised work to smaller companies publish a starting price more often, because price is how they compete for attention. Firms selling integrated programmes to enterprises scope everything in discovery and publish nothing at all. Neither habit predicts quality. Published pricing simply makes a shortlist cheaper to build, which is why it is the first column here.

What moves the price in business to business work

Four things account for most of the spread. The length and complexity of your sales cycle, since programmes aimed at long committee purchases need more content and more patience than transactional ones. The number of channels in scope, because each one adds its own specialists. Whether the agency writes for technical audiences, which requires people who can hold a conversation with your engineers rather than a template. And whether they are being asked to fix measurement, which in most companies means untangling a CRM before any campaign is worth running.

Treat any published starting figure as a floor for the narrowest scope rather than a forecast. A firm advertising a low monthly entry point is usually describing a single channel with a fixed deliverable count, and the programme you actually need may be several times that. Comparing on an identical written scope is the only way to see which of those two numbers you were quoted.

How to tell a real specialist from a general shop in a suit

Ask a candidate to describe your buying committee. A genuine specialist will name the roles, say who blocks a purchase and who champions it, and explain how content differs for each. A general shop will describe personas in the abstract. Ask what they would measure in month three, when no deals have closed yet, because the answer reveals whether they understand that in long cycles the leading indicators are the entire argument.

Then ask for two clients in a comparable sales motion, look at whether the published work is specific or generic, and ask what they would decline to do at your budget. A candidate who cannot name one thing they would refuse is selling a package. In this category the useful supplier is the one who narrows your scope rather than the one who agrees to all of it.

Questions people actually ask

Are agency ranking lists worth anything?

As a source of names, yes. As evidence of quality, no, because placement on most lists reflects entries submitted, reviews solicited and in some cases fees paid. Use them to widen a longlist, then qualify every name against published pricing, disclosed minimums, named clients and a written scope you control.

Should we hire a specialist in our industry?

It helps most where the buyer is technical or the category is regulated, because the cost of a learning curve lands on you. It matters less where the motion is standard and the constraint is execution. Ask candidates to show work in a comparable sales motion rather than only in your exact vertical.

How long should the first contract be?

Long enough for the work to be judged fairly and short enough to leave if it is not working, which in practice usually means a defined initial period followed by a rolling term with reasonable notice. Ask for the minimum term and the notice period as one question, and be wary of long lock ins offered at a discount.

What should we ask for in the monthly report?

Absolute numbers alongside ratios, the agreed definition of a qualified enquiry, the pipeline value attributable to the programme, and the work actually completed that month against what was planned. Insist on your own direct access to the underlying analytics and ad accounts so you can verify any figure yourself.
