Thesis

The healthspan generation is online, wealthy, and under-served.

The over-50 cohort holds 70% of American household wealth and lives another 25 to 35 years after their 50th birthday. Consumer software has spent two decades optimizing for the college graduate — leaving the largest opportunity in the market to founders who assume their users are 27 and unmedicated. We think that's a mistake, and we're building the counter-thesis.

Longevity is the default lens.

The 25-year outcome — VO2 max, HRV, sleep, blood pressure, muscle mass retention — matters more than the six-week transformation.

Medicated users are the default users.

Most adults over 50 take prescription medication. Software that treats this as an edge case ignores its own market.

Community halves churn.

Retention in fitness apps doubles when users bring a friend. In this demographic — spouses, workout partners, foursomes — it triples.

The doctor is a first-class user.

Products in this space should produce artifacts a physician actually wants to see, not just a consumer-facing dashboard.

Where we’re building today.

How we build

Small team. Long horizon. Honest data.

We operate as a small, senior team with no board pressure and no VC clock. That freedom is the whole product plan.

  1. 01

    Build for the reader who’s already there.

    Every product decision assumes the user is medicated, sees a doctor, and already tracks something. Copy, defaults, and UX flow from that.

  2. 02

    Ship transparency as a moat.

    Every score in our software shows its math. Every claim shows its evidence. Every stale metric labels itself stale.

  3. 03

    Community, not virality.

    Our users don’t forward TikToks — they text their brother-in-law. We design for the four-person unit, not the network graph.

  4. 04

    Standalone economics before scale.

    Each portfolio company must reach standalone unit economics before the studio starts the next. No portfolio subsidies.
