“Why did this drop?”
Health, further.
The health data you already have, scattered across wearables, labs, records, and your genes, read together as one private, personalized second opinion.

“Does this affect my Rx?”
Is my HRV crashing because my ferritin dropped?
The data exists. The answer doesn't, and you're the one left to connect it.
Why this matters
Your health is a puzzle, and you’re holding half the pieces. With half, you guess. Read together, the picture is obvious.
Why Further HealthOur solution
Every health marker, unified into one private profile.
The only platform that ingests every major class of consumer health data, and synthesizes across them. Competitors specialize in one slice. Further owns the whole stack and runs the analysis primarily on the user's own machine.
The core loop
- Connect
- Understand
- Act
- Track
- Improve
A second-opinion engine, not another dashboard.
Ranked hypotheses with confidence levels, supporting evidence drawn from the user's own data, and clear validation paths. Observations to discuss with your clinician, not a diagnosis.
Further Genomics
The deepest layer: your DNA, read on your own Mac, with the positions your chip missed filled in.

Why we win
Privacy is architectural, not aspirational.
01 · Storage
Two-tier encrypted vault, on the user's machine.
Tier 1 holds full PHI, encrypted column-by-column with AES-256-GCM under a KEK/DEK split derived from the user's passphrase. Tier 2 is a one-way pseudonymized mirror, the only surface visible to cloud AI.
- Cipher
- AES-256-GCM
- KDF
- Argon2id
- Password rotate
- re-wrap DEK in ms
02 · Egress
Deterministic PHI firewall on every outbound call.
A regex-based firewall with measured 99.9% recall, hardened by clinical BERT and RoBERTa NER models as advisory cross-checks. ML never makes the privacy decision. The gate is deterministic. Any layer detecting PHI hard-blocks.

03 · DNA privacy
Your DNA is your fingerprint and stays on your device.
Genomes can never be revoked or changed. Further parses your raw file locally and reads only the SNPs needed for analysis. Your raw data is never uploaded, never logged, never shared. Same SNP, same finding, every time.
- Parsing
- local-only · raw file never leaves device
- SNPs
- 711 read · 81 active risks
- Pharmacogenomics
- 229+ drugs across 19 enzymes
“The deterministic core is already shipped. KEK/DEK migration, PHI firewall, and the HIF coordinator are all live. Engineered, not described.”
