Triple Whale alternatives for Amazon brands, including Northbeam

Spillmark runs geo holdout tests for Meta ads and measures Amazon orders by ship-to state. It plans the test from your own Amazon order history, picks a group of US states whose past sales track the rest, runs a placebo check, tells you how long the test needs and shows the expected cost before you pause anything.

$19 a month gets the dashboard. Holdout tests start on Starter at $49 a month. Cancel anytime. Read-only, and nothing changes without your approval. Use the Get started button under the introduction.

Against Triple Whale, you give up pixel attribution, Moby, and a package that can also run a media mix model. You use a holdout when the order happens on Amazon, where a store pixel can't see it. Triple Whale's and Northbeam's own descriptions are in the sections after this one.

The method is on how lift is calculated. Size a test with the holdout test calculator before you pause ads.

Triple Whale describes itself as the AI operating system for ecommerce. Its pricing page, as of October 2026, has a Free plan and three paid packages (Foundation, Automate and Enterprise), priced by package and your brand's annual GMV. Here's what each layer does, in Triple Whale's words:

• Attribution. Multi-touch attribution from the Triple Pixel, with eight models to choose from, including first click, last click, linear and Total Impact, which blends tracked touchpoints with post-purchase survey answers.
• Moby. An AI agent. On the Automate package it can adjust budgets, pause ads and launch campaigns within your approval settings and guardrails.
• Compass. Included in Enterprise. It combines attribution, MMM and incrementality, with GeoLift experiments and holdouts. Triple Whale says it's for ecommerce teams with meaningful media spend across multiple channels.
• Amazon. An Amazon Marketplace integration that pulls Amazon sales, ad spend and performance into Triple Whale. The homepage says Compass captures the impact of marketing "from DTC and Amazon to retail."

So Triple Whale does bring Amazon numbers in, and its top package runs geo tests. For a smaller brand, the questions are which package you'd need for testing and how its tests count Amazon orders. Ask both in a demo.

Northbeam calls itself a marketing intelligence platform for profitable growth. As of October 2026, its site describes three products:

• Multi-touch attribution on first-party data, with what it calls unlimited lookback windows and a Clicks + Deterministic Views model that credits ad views as well as clicks.
• MMM+, a media mix model that can take in Northbeam's attribution data and lets you adjust forecasts and budgets daily. The homepage says it covers revenue that's hard to measure on a click basis, including retail revenue.
• Incrementality, with automated test setup. Northbeam says it generates experiment designs from your spend, channel mix, conversion lag and KPIs, keeps test and control groups balanced despite regional variability, and adjusts pacing, spend and cooldowns while a test runs.

The pricing page lists a Starter plan for brands spending less than $1.5 million a year on ads, which its FAQ describes as for Shopify brands. Integration with any ecommerce platform, not just Shopify, starts on the Professional plan, and incrementality is listed as an option on Professional and Enterprise.

As of October 15, 2026, Northbeam's incrementality, attribution, MMM+ and pricing pages don't mention Amazon sales. Its integrations page shows Amazon Ads among the ad platforms it connects. If Amazon is a big share of your sales, ask how a Northbeam test would count Amazon orders.

Attribution, from any vendor, divides credit for orders it can trace back to ads. That's useful for comparing campaigns day to day. It doesn't say how many of those orders would have happened without the ads, and it can't follow a shopper who sees a Meta ad and then buys on Amazon, because a store pixel never sees that purchase. The attribution models guide covers how each model splits credit.

Triple Whale says as much on its Compass page: on its own, multi-touch attribution can't capture influence outside a trackable conversion path. That's why both companies sell incrementality tests alongside attribution. Incrementality is the difference between sales with the ads and sales without them, and the clean way to see it is to switch ads off for one group and compare.

For a brand whose Meta ads also sell on Amazon, the useful test is a geo holdout: pause Meta ads in a group of US states for a few weeks, then compare Amazon orders by ship-to state with the states where ads kept running. The test needs no click tracking at all. The Amazon halo effect calculator gives a rough sense of what Meta reporting leaves out before you test.

If you sell on Amazon and you're comparing Triple Whale, Northbeam or any other measurement tool, these questions separate them:

• Which plan includes incrementality tests, and can I run one without buying the rest of the package?
• Does the test count Amazon orders, or only orders on my own store?
• Who designs the test, and is the design written down before it starts so it can't change once results come in?
• Does each result come with an uncertainty range, and what does the report say when a test can't tell?
• Will the tool change budgets or pause ads on its own, and can I switch that off?

Size a test before you commit to anything with the holdout test calculator. With few orders a day, a test needs more states or more weeks to see a realistic lift. The Facebook ads for Amazon guide covers where to send the traffic in the first place.

Stay with Triple Whale if you want attribution, an agent that can change budgets inside your limits, and an Amazon sales import. Stay with Northbeam if you want first-party attribution and MMM+ and you'll ask how a test counts Amazon orders. Use the holdout when the useful number is Amazon orders the pixel never saw. Haus and Measured are the experiment vendors in the shortlist.
