Introduction
Find your alpha with signal engineering.
Watt indexes and makes the world's signals consumable. A new kind of search, built for AI traversal of petabytes of raw signals. Blend your subject-matter expertise and first-party data with raw signals to do what used to take teams of data engineers, scientists, and analysts in minutes.
We're early! We started with person-level signals and are incredible at building audiences.
Discover the possible
The best way to learn is by doing — follow the quickstart to add Watt to Claude and start exploring the graph, discovering signals, and building audiences.
Learn
Explore the graph
Discover relevant signals and how to leverage them.
Learn
Build an audience
Turn an idea — or a list you own — into a measured audience, then analyze and activate it.
Learn
Shape the graph
Check whether the data you need exists, and tell the team what to index next.
