Case study
Mycelia
A personal health data platform in development under Mycelium Health, designed to organize fragmented health information and support better care conversations.
The problem
Your health information lives in patient portals, lab PDFs, wearable dashboards — and memory. People are expected to make consequential health decisions from that fragmentation, and clinicians are expected to help them in short visits, often without seeing most of the picture.
What I’m building
Mycelia is a personal health data platform currently in development under Mycelium Health, the broader health technology venture and brand I founded. It’s designed so someone can keep labs, medications, wearable data, and their own observations in one organized, understandable place — and use it to show up to appointments with better, source-linked questions instead of a stack of printouts.
The design centers on patient-generated health data and on collaboration with the care team, not around it: the goal is a more prepared patient and a more informed conversation, with the clinician’s judgment where it belongs.
What it is not
Mycelia is not a medical device or a diagnostic tool. It does not diagnose, treat, interpret results, or recommend treatment. It organizes and displays health information to support conversations with a healthcare team — it does not replace clinical judgment.
Evidence stance
Self-tracking is only useful when it’s honest. Mycelia’s approach to personal experiments follows structured n-of-1 principles: one change at a time, a predefined outcome measure, a set duration, and named confounders — including the measurement error baked into consumer wearables. Population evidence comes first; personal data sharpens how that evidence applies to one person. It never replaces it.
Data stewardship
Health data belongs to the person it describes. The design commitment is transparency about what is stored and what is shared — trust is earned, not assumed.
Tools and process
Research, interface design, data modeling, and implementation are done with Claude Code and related tooling — which is how one person can cover ground that would normally take several early-stage specialists. Product decisions, evidence framing, and every claim above stay human-reviewed.
Status
Mycelia is actively being designed and built under Mycelium Health. This page will grow into a dated build log — working screens, data-model decisions, and the reversals that come with real iteration — as development continues.
