What the interviews show. They measure marketing differently, so it's less about which one wins than which method fits your question. Haus runs incrementality and geo-lift experiments — buyers praise its rigorous, finance-credible causal testing, strategic "very smart" reps who help plan tests, and insight that reshapes budget allocation — but flag it as a "black box" on how it calculates, high cost that doesn't fit seasonal usage, and a cumbersome onboarding. Northbeam does always-on multi-touch attribution — buyers praise its transparent, non-black-box "source of truth" and cross-channel integration — but flag a complex onboarding, weak non-digital coverage, and the category's data-reconciliation issue. Some buyers run both: Haus for periodic lift tests, Northbeam for ongoing attribution.

In their own words
The phrases buyers reach for, verbatim, when they describe each platform:
Haus
rigorous incrementality & lift tests method
"very smart reps" plan the tests support
finance-credible, drives budget shifts impact
a "black box" on its calculations opacity
high cost vs. seasonal usage cost
cumbersome, slow onboarding setup
Northbeam
transparent "source of truth" transparency
not a "black box" clarity
cross-channel integration integration
complex onboarding setup
weak on TV & offline coverage
data that doesn't fully reconcile accuracy
Where Haus buyers concentrate their praise
Haus's advantage is causal incrementality testing with strategic support. Buyers describe robust incrementality and geo-lift experiments that deliver clear, persuasive data finance teams understand and fund against, "very smart" reps who help plan tests and turn measurement into strategy, and insight that drives real budget-allocation changes and improves contribution margin. For a team that wants causal proof of what spend is actually incremental — and a partner to run the tests — that rigor and support are the reason it wins. The cautions — repeated across many interviews — are opacity buyers call a "black box" on how it calculates, high cost that doesn't fit seasonal or sporadic usage under annual contracts, and a cumbersome, slow onboarding that stalls on messy internal data.
Where Northbeam buyers concentrate their praise
Northbeam's advantage is transparent, always-on multi-touch attribution. Buyers describe attribution that gives a clear, non-black-box picture they trust as a "source of truth," and comprehensive cross-channel data integration that pulls performance into one continuous view. For a team that wants an ongoing, transparent read on where conversions come from across channels — not a periodic experiment — that transparency and integration are the reason it wins. The cautions — consistent with how buyers talk about Northbeam elsewhere — are a complex, cumbersome onboarding, weak attribution for non-digital channels like TV and billboards, and the category's data-reconciliation issue, where the numbers don't fully match the ad platforms, so buyers verify against them.
Haus vs. Northbeam on cost
Both are premium and both draw cost complaints, so the useful part of this axis is not the gap but the shape of the contract underneath it:
Where buyers place the two against each other on what measurement costs to run. Positions are relative within this pair, not a price scale, and they say nothing about a third platform.
Haus’s cost complaint is about fit, not level. Buyers describe annual contracts against measurement they want in bursts — a lift test before a seasonal push, not a subscription running all year — so a brand with sporadic needs pays for months it does not use. Northbeam’s is always-on by design, which is what makes its premium easier to justify daily and harder to pause. Some teams run both and accept two premium bills, because the questions genuinely differ: what is incremental, and where did this conversion come from.
What buyers wish they'd known
Before picking Haus
Its rigorous incrementality testing, strategic reps, and finance-credible insight are the draw — but buyers flag opacity they call a "black box" on how it calculates, high cost that doesn't fit seasonal or sporadic usage under annual contracts, and a cumbersome onboarding that stalls on messy internal data. Confirm your usage justifies an annual contract, get clarity on how tests are calculated, and budget onboarding time to clean up your data, before you commit.
Before picking Northbeam
Its transparent "source of truth" attribution and cross-channel integration are the draw — but buyers flag a complex onboarding, weak coverage of non-digital channels like TV and billboards, and data that doesn't fully reconcile with the ad platforms. Budget for the onboarding, confirm it covers the channels you run — especially any offline ones — and plan to validate its numbers against the ad platforms, before you rely on it.
Four questions the interviews raise
Buyers cite incrementality and geo-lift tests that prove causal impact.
Buyers cite continuous, transparent multi-touch attribution across channels.
Buyers value the rigor but call its calculations a "black box."
Buyers single out its transparent, non-black-box "source of truth."
Buyers praise "very smart reps" who help plan and interpret tests.
More self-serve; support is less emphasized than transparency.
Buyers flag high cost and annual contracts that don't fit seasonal usage.
Always-on; buyers flag pricing and onboarding as its costs.

The complaints these interviews carry sit on both sides: Haus's are opacity, cost, and onboarding; Northbeam's are onboarding, offline-coverage, and data-reconciliation. Both are part of the shift beyond last-click, as brands look for measurement they can trust — but they take different routes. Because they answer different questions — is this incremental, versus where are conversions coming from — the decision usually tracks which you need, and some buyers run both. Re-check at renewal rather than assume today's picture holds.

Common questions
Haus vs. Northbeam: which is better?
They measure marketing differently, so it's less about which one wins than which method fits your question. Haus runs incrementality and geo-lift experiments — buyers praise its rigorous, finance-credible causal testing, strategic "very smart" reps who help plan tests, and insight that reshapes budget allocation — but flag it as a "black box" on how it calculates, high cost that doesn't fit seasonal usage, and a cumbersome onboarding. Northbeam does always-on multi-touch attribution — buyers praise its transparent, non-black-box "source of truth" and cross-channel integration — but flag a complex onboarding, weak non-digital coverage, and the category's data-reconciliation issue. For a team that wants causal proof of what's incremental and a strategic partner to run tests, buyers lean Haus; for a team that wants transparent, always-on attribution across channels, they lean Northbeam. Notably, some buyers run both — Haus for periodic incrementality tests, Northbeam for ongoing attribution.
What's the difference between Haus and Northbeam?
The difference is the measurement method. Haus is an incrementality and geo-lift experimentation platform — it runs controlled tests to measure the causal, incremental impact of spend, which buyers value for finance-credible proof and strategic support, with the trade of opacity in how it calculates ("black box"), high cost relative to sporadic usage, and a cumbersome onboarding. Northbeam is an always-on multi-touch attribution platform — it tracks and attributes conversions across channels continuously, which buyers value for transparency and cross-channel integration, with the trade of a complex onboarding, weak offline coverage, and data that doesn't fully reconcile. Haus answers is this spend truly incremental? through experiments; Northbeam answers where are conversions coming from? continuously. They're complementary as much as competitive, which is why some buyers run both.
Do I need both Haus and Northbeam?
Some buyers do run both, because they answer different questions. Haus runs incrementality experiments that prove, causally, whether spend is driving incremental results — useful for big budget-allocation decisions and for convincing finance. Northbeam runs always-on multi-touch attribution that tells you, day to day, where conversions are coming from across channels. A team that wants both the periodic causal proof and the continuous cross-channel view may run Haus for lift tests and Northbeam for ongoing attribution, as some buyers in the corpus do. But it's not required: a team focused on causal, experiment-based measurement can run Haus alone, and a team that wants transparent always-on attribution can run Northbeam alone. Decide whether your priority is causal proof, continuous attribution, or both — and weigh the combined cost, since neither is cheap.
Is Haus or Northbeam more transparent?
Transparency is where Northbeam has the clearer edge in the interviews. Northbeam is specifically praised as a transparent "source of truth" that isn't a "black box" — buyers value being able to see how the attribution is built. Haus, by contrast, draws a black-box criticism: a buyer described its calculations as opaque and secretive, which left them skeptical of the results. That's partly inherent to the method — incrementality models are harder to fully expose than attribution paths — but it's a real difference buyers feel. So if seeing how the number is constructed matters most, buyers lean Northbeam; if you want causal, experiment-based proof and will accept some model opacity for it, Haus is the trade. Either way, buyers validate measurement against their own results rather than trusting one tool as gospel.
