The assumption I got wrong
For three years I ran growth for consumer businesses — first at a marketplace, then in telco lifecycle marketing, where a single campaign could reach millions of customers in a week.
When I moved into B2B demand generation, I assumed the mechanics would be identical and only the audience size would change. Smaller numbers, same machine.
That assumption cost me most of my first quarter.
The mechanics are genuinely different. But the thinking transfers almost entirely — and that turned out to be the more valuable half. Here's how I'd split it now.
What transfers: segmentation as a reflex
In B2C you segment because you have no choice. With millions of customers, "send everyone the same message" isn't a strategy, it's an abdication. You learn to build segments from behaviour — what someone did, how recently, how often — rather than from who they claim to be.
Most B2B teams I met were segmenting on firmographics alone: industry, headcount, revenue band. Useful, but static. It tells you who someone is and nothing about whether they're in market.
The B2C reflex — what did this account actually do in the last 30 days? — is the single most useful thing I brought with me. Pricing page visits, documentation reads, repeat sessions from multiple people at the same company. These signals existed in the data the whole time. Nobody was building segments from them.
What transfers: the experimentation cadence
Consumer growth teams ship tests weekly because the feedback arrives in days. That cadence becomes muscle memory: hypothesis, test, read, decide, next.
B2B teams often run one big campaign a quarter and call the post-mortem "learning." The sample sizes are smaller and the cycles are longer, so weekly testing on conversions is genuinely impossible.
But you can keep the cadence by moving it upstream. Test the things that produce fast signal — ad creative, subject lines, landing page structure, form length, headline framing — and let the slow metrics accumulate underneath. The discipline survives even when the measurement window doesn't.
What doesn't transfer: volume logic
In B2C, more traffic is almost always progress. Scale a channel that converts and you win.
In B2B, more traffic is frequently the problem. My first instinct at Multinet was to optimise for lead volume, because that's the number I'd always been rewarded for. Volume went up. Nothing downstream changed.
The reason is simple arithmetic. If your addressable market is 4,000 companies, growth doesn't come from reaching more of them — you can reach all of them. It comes from reaching the right 400 more effectively, more often, with a more specific message.
That is a completely different job, and no amount of channel-scaling experience prepares you for it.
What doesn't transfer: the feedback loop
Consumer marketing gives you an answer today. Ship a campaign, watch the curve, know by Thursday.
B2B gives you an answer in three months, filtered through a sales team that may or may not have followed up, on deals that may or may not have closed for reasons unrelated to marketing.
This changes what you can honestly claim. Early on I kept reporting on metrics I could measure quickly — clicks, form fills, cost per lead — because they were available, not because they mattered. They made the work look successful while the pipeline stayed flat.
The fix wasn't better attribution. It was accepting a slower reporting rhythm and agreeing with sales, in advance, on what we would judge the quarter by.
What doesn't transfer: "the customer" is not a person
The hardest adjustment. In B2C I optimised for one individual making a small, fast, largely emotional decision.
In B2B there are five or six people involved. The person who finds you is rarely the person who signs. The person who signs may never visit your website. Each of them needs different information, and they talk to each other when you're not in the room.
Practically, this means a single conversion path is never enough. The researcher wants depth and evidence. The economic buyer wants a business case in one page. The technical evaluator wants to know what breaks. If your funnel only serves the first one, deals stall at exactly the point where you stop being able to see them.
The reframe that worked
I stopped thinking of demand generation as acquisition at a different scale and started thinking of it as making a small number of the right conversations happen sooner.
That framing changed the metrics I argued for, the channels I defended, and how I described my job to people who weren't in marketing.
Everything I learned in B2C about behaviour, testing, and segmentation still applies. It just points at a much smaller, much more specific target — and the accuracy matters far more than the reach.
