Most nurture sequences are built as a progression of depth: a light asset, then a heavier one, then an offer. That is a reasonable model for one person. It is a poor model for a purchase where several people with genuinely conflicting priorities have to reach agreement.
Research on complex B2B purchases has consistently found buying groups running to roughly six to eleven people, and the practical implication is rarely acted on: the obstacle is usually not persuading a buyer, it is helping a group that disagrees with itself arrive at a shared decision.
Why one message fails across a committee
Take a data infrastructure purchase. Three functions, three incompatible concerns:
- Engineering is worried about migration risk and about being the team that has to run the thing at 3am. It wants architecture, failure modes, and honesty about what breaks.
- Finance is worried about total cost over three years and about a renewal that ratchets. It wants pricing mechanics, not benefit claims.
- Operations is worried about the transition period and about whether its team has to learn something new mid-quarter. It wants a rollout plan.
A single ad that addresses all three says something so general it addresses none of them — "reduce risk, cut cost, and simplify operations" is a sentence every vendor in the category could run. Meanwhile the specific ad that would genuinely help engineering makes finance's eyes glaze, which is fine, because finance is not who it is for.
You are not moving an account through a funnel. You are helping three people build an argument they can make to each other when you are not in the room.
Mapping the disagreement
Before building any sequence, write down — for a real deal you won and a real deal you lost — who was involved, what each of them was worried about, and where the internal argument stalled. Ten minutes with the AE who ran each deal is more useful than any persona document.
What you are looking for is the blocking concern: the objection that, unresolved, stops the purchase regardless of how enthusiastic everyone else is. In most categories there are one or two, they belong to a specific function, and they are rarely the thing your marketing leads with.
Sequencing by function, not just by depth
A structure that works for a considered purchase with a three-to-six month cycle:
Weeks 1–3 · Establish the problem, broadly
One message, all functions, aimed at the cost of the status quo rather than at your product. Everyone needs to agree there is a problem before anyone cares about a solution. Measure: accounts reached, functions reached per account.
Weeks 3–8 · Split by function
The stage that most programmes skip. Three parallel tracks, each addressing one function's real concern in that function's vocabulary. Engineering gets the architecture piece; finance gets the cost model; operations gets the rollout plan.
You will feel like you are fragmenting the message. You are — deliberately. The unifying story is being assembled inside the account, by the people who have to live with the decision, and your job is to give each of them the piece they need.
Weeks 8–12 · Converge on the internal argument
Now one message again, but a different kind: material that helps the group decide together. A comparison document, a risk assessment, a reference story that names the same three concerns and how another company resolved them.
Week 12+ · A proportionate offer
Only to accounts where multiple functions have engaged. A workshop, an assessment, a technical deep-dive with a named person. Not a generic demo request, which asks a committee that has done twelve weeks of work to start again at the beginning.
Arming the champion
The highest-leverage asset in most B2B nurtures is not aimed at the buyer at all. It is the thing your champion forwards internally.
That asset has different requirements: it must stand alone without you in the room, it must be honest about trade-offs (a champion who forwards a puff piece loses credibility, and will not forward the next one), and it must be short enough that a busy VP reads it. A two-page cost model with your weaknesses acknowledged does more work than a twelve-page whitepaper.
Ask your best customers what they sent around internally. It is almost never the asset you would have guessed.
What to measure
Three things, in order of usefulness:
- Functions engaged per account, over time. The single most predictive number in committee-based selling. One to two is the transition that matters.
- Whether the blocking function is present. If engineering is the usual blocker and engineering has never engaged at an account, that account is not progressing regardless of how warm marketing looks.
- Time from first touch to second function. A leading indicator of whether the split-by-function stage is working. If it lengthens, your function-specific creative is not landing.
None of these are visible in standard campaign reporting, which is a large part of why the split-by-function stage gets cut — it is the stage whose value is hardest to see in the tools most teams look at.
