What does Watt index?
What the Signal Graph holds, where every signal comes from, and why the moat is the graph — not the sourcing.
Watt's Signal Graph holds over 160,000 signals across hundreds of millions of entities and the billions of identifiers they hold. Every one of those signals comes from somewhere — we don't generate any of it ourselves. Watt is signal infrastructure, not data collection.
What's in the graph today
Watt is working toward indexing all of the world's raw signals. That's the long arc. In year one, our focus is people-level signals — and the graph is already dense and powerful there, even though there's far more still to index on people.
Want signals that aren't in the graph yet? You can request them through the plugin — it helps us prioritize what to index next.
- People — our focus. Dense and powerful today, with much more still to come.
- Business — solid coverage.
- Everything else — light to non-existent for now.
A handful of vendors, hundreds of sources underneath
Today the Signal Graph indexes signals from two primary vendors:
- RevenueBase makes the B2B signals available — the same underlying data layer that powers most of the legacy B2B providers: firmographics, technographics, hiring signals, and the rest of the B2B stack.
- DataMoon makes the consumer signals available — identity signals, purchase intent, life events, interests, lifestyle, household composition, and the rest of the B2C stack.
Each of these vendors represents hundreds of upstream data sources of their own. So while we hold only two contracts, the signals flowing into the Signal Graph are sourced from thousands of underlying providers.
That number will grow. As Watt scales, we'll add more direct vendor relationships and move further upstream toward source-of-truth providers wherever possible. Fewer hands on the data means higher fidelity.
Every signal is on the open market
Every signal currently in the Signal Graph is available on the open market to anyone who knows where to look. We don't have exclusive licensing. We don't have proprietary collection. No dataset in the graph reaches customers only through Watt. If you wanted to assemble the same raw signals we work with, you could.
The reason most don't is that the work isn't in the sourcing. It's in consuming enormous amounts of raw signals.
Why fewer hands on the data matters
Commercial data passes through numerous layers before it reaches a buyer: companies generate raw behavioral data at the source (purchases, deliveries, ad impressions), derivative companies build signals on top of it, middlemen repackage those, and aggregators resell the bundles. By the time data reaches an analyst, marketer, or executive, it may have crossed three or four of these layers.
Every hand degrades fidelity: each step compresses raw signal into a pre-built summary and discards detail an agent might later want to reason over. The closer Watt sources to the original event, the more raw the signal is when it enters the graph — and the more there is to compose against. That's why we go as far upstream as possible when evaluating a vendor.
How a signal gets into the Signal Graph
Onboarding a new vendor takes several months today. Our goal is to get it under one day and eventually make it fully self-service. We're not there yet.
Qualification
Does this vendor have signals that are net-new to the graph, or that improve signals we already have? What's the lineage? How fresh is the data? What's the coverage? How accurate is it?
Ingestion
If they pass that bar, we build a pipeline to feed the vendor's data into the base graph. This is technically non-trivial — data vendors are notoriously inconsistent: formats change, delivery schedules slip, signals arrive on uneven cadences. There's no off-the-shelf tooling for this, because the Signal Graph is a novel database.
Daily recalculation
Once ingested, data flows into the base graph asynchronously, on whatever cadence the vendor delivers. The Signal Graph itself recalculates every day, incorporating everything that has arrived since the last cycle.
What we don't do
- We don't collect any data ourselves. No first-party tracking, no SDK, no cookies on consumer browsers, no observation of end users. Every signal in the graph comes from a licensed vendor.
- We don't sell data. Watt is the technology layer that searches, indexes, reasons over, scores, and composes signals. The vendor that makes a signal available stays responsible for it, and for the rights, consents, and restrictions attached to it.
- We don't have exclusive relationships today. That will change as we grow — there's a future where signals reach the graph before they reach anywhere else, simply by being first to index them. But that's not the current state, and we won't pretend otherwise.
- We don't operate outside the US. Everything in the graph is US-only. We've deliberately turned down deals to stay out of GDPR jurisdictions while we focus on building the US market.
