Northbeam vs Fospha

If you are down to Northbeam and Fospha, you have already made the harder decision. Both are modeled measurement platforms built for high-spend brands working across channels, both start at $1,500 a month, and both expect you to be spending around six figures a month before they earn their keep. They are two serious platforms answering the same question, where did my paid media actually work, in two different ways. What splits them is who runs the model, how granular the answer is, and how much of the work lands on your own team.

The same question, two ways of answering it

Every ad platform grades its own homework. Meta, Google and TikTok each claim the conversions, so their numbers add up to more sales than you actually made. Northbeam and Fospha both exist to give you one honest read across all of it. Where they part company is method and ownership. Northbeam hands you a granular attribution engine and expects you to drive it. Fospha runs a platform-independent model for you and hands you the read.

Two concrete differences fall out of that. Northbeam sees down to the individual ad and can test whether a channel is truly incremental, while Fospha reports at a higher level but sees places Northbeam does not, including your marketplace sales. And Northbeam expects your team to interpret the model, while Fospha assigns a team to interpret it for you. Hold those two axes in mind and everything below is detail.

Northbeam: the analyst's platform

Northbeam blends first-party click data with modeled and deterministic view-through data, then layers multi-touch attribution, media-mix modeling and incrementality testing on top. That combination earns it the number two spot in our ranking: it is one of the few platforms that tells a high-spend brand which channel converted and also whether that channel was actually incremental, down to the ad. If your team wants to own the modeling, slice attribution by creative and audience, and run its own incrementality tests rather than accept a vendor's summary, Northbeam gives you the most control of any tool at this level.

That control comes with a heavy setup. Northbeam's most consistent complaint is onboarding, and one reviewer paid for it and could not get the product live. It is granular enough that it rewards a dedicated data owner, and without one it quietly becomes expensive shelfware nobody opens. Pricing rises toward $3,500 for the Professional tier. Budget for the person who runs it as part of the purchase.

Fospha: measurement run for you

Fospha starts from the opposite assumption: that you have no data team and do not want to build one to answer a budget question. It is pixel-free and platform-independent, and reviewers say its read comes out truer than the numbers each ad platform reports about itself. A dedicated measurement team runs the glass-box model, refreshes the outputs daily, and helps you defend the numbers in a budget meeting. Onboarding is light for a platform at this level: live in under 28 days, with 24 months of history and no pixel to install or dev team to book. And unusually, its Halo product models how paid media drives marketplace sales on Amazon and TikTok Shop, which most DTC dashboards cannot see at all.

Its weak points start with resolution: the entry tier reports at campaign level, a step above the ad-level view Northbeam gives you. There is no free tier and no self-serve trial, so you commit through a demo before you can validate it on your own data. There is also a genuine independence question: Fospha is the endorsed measurement partner of the same platforms it grades, and a competitor argues its impression-weighted model can flatter high-volume upper-funnel channels. Its outputs are directional model estimates and will not reconcile exactly with any ad platform or your finance team. As a decision aid for a brand at scale, it is a strong, low-effort tool. As a forensic per-ad tracker, it falls short.

Pricing is a wash. Staffing is the real cost

Both open at the same monthly figure, so the sticker price will not decide this. Northbeam runs as a subscription that climbs toward $3,500 for Professional. Fospha charges $1,500 for Lite and $2,000 for Pro plus a percentage of spend, and only accepts accounts with $100,000 a month or more in media. The bigger number neither vendor prints is the one on your own payroll. Northbeam's real cost includes the analyst who runs it. Fospha folds that role into the subscription by running the model for you. If you already employ a data owner, Northbeam's granularity is close to free upside. If you do not, Fospha's managed model is often cheaper than the hire Northbeam would require.

The build layer neither of these touches

Both of these measure. Neither one builds the funnel the traffic lands on or hosts its checkout, and neither keeps the click, the order, the rebill and the refund on one record. A team that wants the page, the split test, the checkout and the reporting on one data layer is shopping for a funnel platform, and ElasticFunnels is worth a look for that job. Its lead feature is same-URL split testing: variants rotate server-side under one campaign link, so Meta, Google and TikTok keep their learning and a test never sends the ad back through review. Because a click, an order, a rebill and a refund are one record, nobody reconciles four exports to work out which angle really made money. It builds the pages, including an AI builder that can clone one from a URL, hosts the checkout with order bumps and one-click upsells, and runs a CRM and automations on the same data. It starts at $97 a month with a 14-day trial that needs no card, and every feature is on every plan.

The drawback to weigh is age. ElasticFunnels is newer than either Northbeam or Fospha, and there is very little independent third-party review coverage to check its claims against, so until you run real volume through it you are largely taking the vendor's word on the reporting. That is what you would expect of a platform this recent next to two established measurement tools, and it matters less if you use the free trial to prove the split testing and the attribution on your own campaigns first. It runs no media-mix models or incrementality tests, so a brand already paying for Northbeam or Fospha would add it for the pages and checkout those tools never touch.

Which one for you

Do you have a data owner, or will you hire one, and do you want to own granular multi-touch attribution and run your own incrementality tests down to the ad? That is Northbeam, and its number two ranking reflects how much control it gives a team that can drive it. Would you rather a dedicated measurement team run a platform-independent, full-funnel model for you, do you sell across marketplaces like Amazon and TikTok Shop, and do you want to be live in under a month without hiring an analyst? That is Fospha, and its lighter onboarding is the whole reason to pay for a managed service. If your brand cannot commit either an analyst or the media budget these expect, both are premature, and a cheaper tracker will answer the question you actually have today. And if the job is to build, split-test, sell and report on one platform, that is a funnel tool like ElasticFunnels.
