Intro
You’ve probably read that marketing mix modeling doesn’t work for B2B, that long sales cycles and lower deal volume make it statistically unreliable. That concern isn’t made up. MMM was built for B2C: high-frequency purchases, short cycles, lots of data points. Applied naively to B2B, low deal volume and long time lags can break a model’s statistical power. But “MMM doesn’t work for B2B” isn’t quite the right conclusion. It’s closer to “MMM built the way it’s built for B2C doesn’t work for B2B.” Here’s the distinction.
The Real Problem: Volume
A mid-market B2B company might close 100 deals a year. A B2C brand might see 100 transactions a day. If a model only counts closed deals, a mid-market B2B company doesn’t generate enough data points for a reliable estimate. And the lag between a marketing touch and a closed deal, sometimes 6, 12, even 18 months, makes it hard to connect activity to outcomes if the model isn’t built to handle that gap. This part of the objection is fair.
What Fixes It
Before Align BI, I was at Adobe, where our B2C team was trying to get MMM working for our B2B business unit. The model was struggling because it was only counting closed deals, the scarcest and most lagging signal in the whole funnel. When I took it on, I moved the model up the funnel to an earlier success event with real volume behind it, and the models started getting better. That one shift is the difference between “MMM doesn’t work for B2B” and “MMM doesn’t work if you’re only counting closed deals.”
Note however that moving the model up the funnel only helps if you also account for what happens to lower funnel stages. Every funnel has bottlenecks, and conversion rates don’t hold steady just because you’re now measuring earlier. A model that tracks upper-funnel volume without understanding where it stalls on the way to revenue can be just as misleading as one that only counts closed deals. This is genuinely hard and it’s part of what we’re actively building into our own model. It’s also the right question to ask any MMM vendor: do they account for what happens to subsequent stages?
The Other Barrier That Kept B2B Teams Away: Cost
The “MMM doesn’t work for B2B” narrative leaves out another simpler explanation: traditional MMM has always been expensive, expensive enough that only the largest brands could justify it. B2B companies weren’t left out because the statistics were impossible. They were left out because the tools were priced for the largest CPG companies. As costs come down, more B2B companies can finally test whether it works for them.
Summary: What Changes the Math
- Model the full funnel, not just closed deals. Closed-won deals are the scarcest data point in B2B, but pipeline creation and stage transitions happen far more often. We often build models on stage volumes in the hundreds per month, well above what closed-deal counts alone would support.
- Aggregate over enough time. 18 to 24 months of historical data gives patterns room to emerge even with lower per-month volume.
- Build lag in directly. The model accounts for lagging and cumulative effects over time, connecting a touch today to a deal that doesn’t close for months, instead of assuming immediate impact.
- It doesn’t take a massive budget. We’ve built working models on annual marketing budgets as small as $300K, small relative to what traditional MMM assumed was necessary.
- Simulate the rest of the funnel (we’re building this now). Remember that increasing an upper funnel stage doesn’t necessarily increase a lower funnel stage if your funnel has bottlenecks. A true B2B MMM should understand these bottlenecks and ideally include them as part of the optimization.
Where the Concern Is Still Valid
A company with only a handful of customers, a very lumpy enterprise deal flow, or very low marketing spend may not have enough signal for a reliable model, no matter how it’s built.
The Practical Takeaway
For established B2B companies with a steady, even if lower-volume, flow of pipeline activity, long sales cycles are a design constraint to build around, not a disqualifier. And to be honest, even a mediocre B2B MMM is head and shoulders better than an attribution model for allocating budgets. Attribution models aren’t optimization models.
