01 — PROBLEM

Medicine treats autoimmune disease in fifteen-minute snapshots.

An autoimmune patient sees a specialist three or four times a year. The disease happens every day in between. Symptoms, triggers, flares, the effect of sleep, stress, and food go uncaptured. Care is built on what a patient can recall in a short visit months apart. It is reactive, generic, and late.

Annual US economic burden for treatment. $12K–$100K+ per patient per year, of which biologics for autoimmune and rare conditions are the fastest rising — some now exceeding $60K annually.

03 — EVIDENCE

Autoimmunity moves with daily life, so the intervention has to live there too.

01

Immunity is written by environment, not genome

Brodin et al., Cell 2015

02

Specific exposures are causal triggers

Bjornevik et al., Science 2022

03

Change the inputs, the disease changes

Agrawal et al. · Levine et al. 2019

04

So the science points to a daily companion

04 — WHY NOW

The pieces finally fit together.

01Science

Autoimmunity is now recognized as multifactorial

Research confirms the role of lifestyle, environment, stress, sleep, nutrition and hormones in disease progression.

02Technology

Wearables & AI make continuous personal intelligence possible

Wearables, sensors and AI make it possible to continuously track relevant signals at scale and turn it into personal guidance.

03Behavior

People are ready for proactive, personalized care

71% US adults use health apps showing people want to be active partners in their health.

For the first time, continuous autoimmune intelligence is possible.

First NIH-wide Immune Disease Research Strategic Plan (2026 – 2030).

05 — WHY US?

Lived experience. Technical execution. Clinical authority.

Buddy's Observation

Your pain and fatigue rose as both patterns overlapped

Your symptom severity averaged 6.1 this week, up from 5.0 last week. We noticed more stress, less sleep, and that your cycle is in the luteal phase. You also logged fewer nourishing meals and less breathwork than usual. This may be a useful pattern to watch.
