New Sahha API Turning Health Data Into Personas, Powering Hyper-Personalized Engagement

Sahha, the behavioral health and lifestyle data company powering next-gen fitness and wellbeing products, today announced the public release of Sahha Archetypes, an API that transforms complex health data into simple, intuitive labels like night owl, highly active, or short sleeper. By mapping long-term patterns in activity, sleep, mental wellness and readiness, Archetypes provide a turnkey way for developers to understand who their users are and how they live, no clustering models required.

“Clicks and views alone don’t tell you much in the world of fitness and wellbeing. Serious companies need tangible data to build better, more relatable products,” said Aleks Dahlberg, Founder of Sahha. “With Archetypes, we turn raw signals into living personas, so digital experiences can behave more like a coach who truly ‘gets’ you and even adapt as your habits evolve.”

Instead of raw numbers, the API returns ready-to-use labels refreshed weekly or monthly. These fall into two types: ordinal (ranked, e.g., very-short → short → average → long sleeper) and categorical (distinct, e.g., early bird, night owl). This structure allows teams to benchmark progress, trigger context-aware nudges, and build lifestyle-aware UX in minutes.

As health, lifestyle and now longevity brands increasingly adopt generative AI to personalize user experiences, they require more than just raw data they need structured, meaningful insight. While APIs for collecting health data from wearables exist, making that data usable for people and AI is the real challenge. That’s where Sahha’s focus lies: turning raw signals into usable insights through its suite of Scores, Insights, and now Archetypes.

“Sahha Scores are the snapshot; Archetypes are the character arc,” added Sugam Budhraja, Head of Data & Science at Sahha. “Because they smooth out day-to-day noise, they’re perfect for automations, cohort analysis, and long-term habit change.”

Key capabilities developers can ship with one integration:

• Persona segmentation – group users by real behaviours and traits, not assumptions.
• Dynamic user journeys – trigger emails, push notifications or in-app flows tailored to night-owls vs. early-risers, sedentary vs. highly-active, and more.
• Cohort & retention analytics – compare engagement, LTV or outcomes between Archetype groups over time to refine strategy.
• Adaptive labels – weekly/monthly refresh captures evolving habits while historical back-fill provides two weeks of retrospective context at onboarding.
• Device-agnostic – works for smartphone-only and wearable users alike.

Archetypes join Scores, Biomarkers, and Insights in Sahha’s 2025 product suite, offering developers a complete pipeline from granular signals to high-level intelligence for crafting human-centric health and wellness experiences.

The Archetypes API is available today for all Sahha partners. Learn more at www.sahha.ai or reach out for a demo at www.sahha.ai/start.
