Common questions.
What is a behavioral archetype?
A stable, human-readable label — such as Early Riser, Short Sleeper, or Highly Active — derived from weeks of a user’s health and lifestyle data, rather than a single point-in-time score.
How many archetypes are there?
14 archetypes spanning sleep, exercise, mental wellness, and overall lifestyle. Each is either ordinal (a ranked scale) or categorical (a discrete bucket).
How long before a user gets an archetype?
Archetypes are observation-level and need enough history to be stable — typically a couple of weeks of data. 13 of the 14 compute from smartphone data alone; only one (sleep_efficiency) needs a wearable.
How do I use archetypes in my existing tools?
Sahha exposes archetypes over the REST API and emits webhook events on archetype transitions, so you can push them as profile attributes into CDPs and marketing platforms like Klaviyo, Braze, and Segment — and segment, route, and automate in the tools you already use.
How are archetypes different from health scores?
Scores answer “how is this user today?” Archetypes answer “who is this user over time?” — stable labels for segmentation and personalization rather than real-time state.
