Existing spend
Users already pay for wearables and labs
Transit sits on top of behavior that already exists instead of asking for new hardware first.
For people who actively track their health and performance
Transit unifies wearables, lab uploads and health records into one weekly decision layer for recovery, training load, sleep and biomarker-guided action.
See plans See dashboard previewTransit turns wearables, labs, and uploads into one weekly decision layer.
Connect wearables, bloodwork and uploads in one place instead of stitching together Whoop, Garmin, Strava, Apple Health and PDF reports by hand.
See how it works
Reference profiles, biological-age context and status flags turn lab results into something usable instead of another isolated report with no decision layer.
See how it works
Transit Companion translates trends into focused next steps for recovery, training load, sleep and follow-up testing.
See how it works
Longitudinal markers, latest values and alerts make it obvious where momentum is improving, where it is slipping and what to review next.
See how it works
For people already using wearables, bloodwork and health apps who want better decisions on recovery, load, sleep and biomarker follow-up.
Connect wearables, bloodwork and uploads in one decision view.
See what actually changed this week across readiness, biomarkers and training stress.
Leave the dashboard with concrete next actions instead of more raw charts.
Best fit today: people with recurring wearable, lab and health-app data who want clearer weekly decisions.
See Transit+ for individuals For AI Agents & ToolsTransit can also act as the user-owned health data layer for AI agents and third-party tools that need authenticated health context, sync status and AI-generated outputs.
Give a personal AI agent one place to read biomarker context, trends and integration state.
Power summaries, alerts and recommendations without rebuilding the full health data layer from scratch.
Start self-serve with existing Transit accounts and authenticated user access.
Secondary story by design: the B2C product remains the first wedge, the platform extends distribution and retention.

The first wedge is not "solve all of health." It is to own the weekly decision layer for users who already pay for data but still do the synthesis manually.

Pain today
Data is fragmented, decisions are still manual
Most alternatives offer raw dashboards or generic guidance, not one operating layer.
Retention loop
Fresh inputs make the product more useful
Each sync, upload and weekly plan increases value instead of just adding noise.
Expansion path
Start with B2C utility, extend through API usage
Win performance and biomarker decisions first, then let trusted tools and agents build on the same user-owned health context.
