Northbeam
Measures your advertising.

Runs its own pixel on your site and attributes your revenue back to the campaigns, ad sets and ads that produced it.

Watt Data
Analyzes your audience.

Takes a plain description of your company or product and returns how many people buy in your category, what they are shopping for, and how you should reach them.

The difference

Northbeam measures the money you already spent. Watt describes the market you have not spent against yet.

Northbeam tells you where your money went. Its answers come from your own site and your own ad accounts, measured by a pixel Northbeam installs rather than taken from what the platforms report. That is why the CAC it shows you often disagrees with the number inside Meta or Google. Northbeam says the difference is deliberate: it "creates an entirely new set of performance data for all your ads." Setup runs 2 to 4 weeks for Shopify brands and 4 to 8 weeks for everyone else, so the first answer is a month or two away.

None of that setup reaches anyone who has not already come to you. The pixel fires when someone lands on your site, so people who have never seen your ads are not in the data, and no report or export will show them to you.

Watt starts from the market instead. Describe your company or product and it returns who buys in your category, what they are shopping for now, and how to reach them, whether or not those people have met your brand. You can also import Northbeam data and ask about the customers it covers: who bought from the campaigns that worked, who else in the market looks like those buyers, and what that group is buying this month.

Watt Data vs. Northbeam

What are their reports based on?
NorthbeamYour own traffic and orders. A Northbeam pixel records visits and touchpoints on your site, orders arrive from Shopify or the Orders API, and machine learning models split each order's revenue across the touchpoints that led to it. Media mix modeling and incrementality tests run on that same first-party base.
Watt DataWhat people are doing now, ranked by what separates your buyers from everyone else. Bring your campaign, creative, customer list or performance numbers and Watt builds recommendations from those, too.
Where does their data come from?
NorthbeamYours, collected by Northbeam rather than read from the platforms: its own pixel, a first-party DNS record, your order feed, and read access to your ad accounts.
Watt DataWatt's Signal Graph: 172,269 live behavioral signals on what people are buying and searching for, built from transaction and search data, re-scored every day.
What does the data cover?
NorthbeamYour connected accounts and the visits your pixel recorded. Northbeam publishes company-wide totals of "$25 billion" in ad spend tracked and "2.1 trillion" impressions measured, but those figures describe the business rather than a dataset you can query about people.
Watt DataWatt's Signal Graph incorporates 287.9M people and 64.9M businesses.
What do I need to get started?
NorthbeamA sales call, then an implementation. Northbeam publishes in 2 to 4 weeks for Shopify brands and 4 to 8 weeks for everyone else, covering pixel install, a DNS record, the order feed, ad account connections at admin level, and UTMs across every channel. The Starter plan supports Shopify only. Other platforms need Professional or Enterprise.
Watt DataA plain description of your company or product. No ad history, no pixel, nothing to connect. Connect your own first-party customer data for deeper analysis.
What's the output?
NorthbeamAttribution dashboards, a model comparison tool, creative analytics, product analytics, revenue forecasts and budget scenarios, incrementality test designs, and exports to S3 or GCS. An MCP server lets Claude or ChatGPT query the account, on Professional and Enterprise plans.
Watt DataDecision intelligence and recommendations based on who your buyers are, what they are in-market for now, how many US adults fit, and the attributes behind each recommendation. Ask a followup question and Watt answers that, too.
How much does it cost?
NorthbeamEvery plan is quoted by sales. Northbeam publishes entry rates of $1,500 for Starter and $3,500 a month for Professional, with Growth and Enterprise custom, and states "Your monthly price is informed by the volume of data in your business (measured in pageviews)." Professional and Enterprise run on annual terms.

What Watt does that Northbeam does not

Describe people who have never visited your site. Who they are and what they are buying, following and searching for, across US adults. Northbeam has no way to see them, because its pixel needs a visit before it can record any data.

Tell you who your winning ads worked on. Northbeam tells you which ad produced the revenue. It does not describe the person on the other side, which is the input your next round of creative rests on.

Tell you what to charge and what to offer. What this group will pay and the offers that resonate, read from what they buy elsewhere in the market.

Size a group before you spend against it. How many US adults are in your market, and how the count moves as you widen or tighten the definition.

Work before any of your tracking exists. No pixel, no DNS record, no UTM discipline and no implementation window. A plain description of your company or product is enough to start.

What Northbeam does that Watt does not

Attribute your revenue to your spend. Multi-touch attribution across every connected channel, with configurable models, lookback windows and accounting modes. Watt is not an attribution tool and will not replace one.

Model your media mix and forecast it. MMM+ retrains daily, accepts variables outside your marketing, and runs budget scenarios across channels.

Design and run incrementality tests. Northbeam builds the experiment design from spend, channel mix, conversion lag and your KPIs, then manages pacing and validation while the test runs.

Read your creative continuously, without being asked. Northbeam is connected to your ad accounts, so Creative Analytics tracks every variation's metrics as it runs.

Should you use Watt or Northbeam?

Choose Northbeam

When you are spending enough that attribution is the expensive question. Which channel actually produced the revenue, what your real CAC is once ad views are counted, and whether a channel is incremental at all. Northbeam sizes its own plans by ad spend, from brands under $1.5m a year through to teams above $500k a month, which is a fair guide to where it fits.

Choose Watt

When you need a better understanding of the market and your potential customers. Who else buys like your best customers, how many of them there are, what they are shopping for this month, and what a campaign aimed at them should claim. Closer to a data analyst than to another tool in the stack: ask a question in plain language and Watt works through the answer with you.

Use both

Northbeam tells you that a channel stopped working and where the money went. It cannot tell you who the replacement ad should be written for, because the person you have not reached yet was never in the dataset. Run the Northbeam read, then paste the campaigns that worked into Watt and ask who bought from them and who else in the market looks like those buyers.

Questions, answered

Is Watt Data an alternative to Northbeam?

No. Northbeam tells you which campaigns produced revenue, from a pixel that only fires when someone visits your site. Watt describes people who have never been there. To replace Northbeam, look at Triple Whale and the other ecommerce measurement platforms. To learn about the people who have never visited, three products do different things: LiveRamp sells audience segments you activate in ad platforms, SparkToro shows where a group pays attention online, and Watt shows what they buy.

How much does Northbeam cost?

Every plan is quoted by sales, and the published rates are entry points rather than prices. Northbeam publishes $1,500 for Starter and $3,500 a month for Professional, with Growth and Enterprise custom, and states "Your monthly price is informed by the volume of data in your business (measured in pageviews)." Professional and Enterprise run on annual terms. Every tier carries a demo request rather than a checkout, so there is no way to find your own number without a sales call. Watt is free to try with no sign-up.

Should I use Northbeam or Watt to decide what the next campaign should say?

Northbeam when the winning concept is still in the account and you want to spend behind it correctly. Watt when the account has plateaued, or when there is no account yet. Northbeam answers from performance: which ads and channels produced revenue, and what happens if you move budget. That works when something is already working. At launch it has nothing to read, because your touchpoints do not exist yet. Watt answers from the customer: what your buyers are purchasing, following and in-market for, with the segment and attributes named behind each recommendation. Use it at zero to one, and when every new ad has become a variation of the last, because a pattern drawn from campaigns that already ran cannot produce a claim you have never tested.

What does Northbeam not do?

It does not describe anyone who has not already reached your site. Northbeam builds its data from its own pixel, its own DNS record and your order feed. Nothing enters it until someone arrives on your site, so a person who has never met your brand never appears there at all, and no view, model or export will find them.

Can I use Watt and Northbeam together?

Yes. They read different populations, so running both is the normal arrangement rather than a compromise. Northbeam tells you which campaigns produced revenue and what your real cost per acquisition is. Paste that result into Watt and ask who those customers are. Who bought from those campaigns, who else in the market looks like them, what they are shopping for this month, and what they will pay.
