precision-health stack§01 The stack
Everything a longevity platform needs to measure, model and act on a person's biology — built once by Waven, and offered as one stack. Select a layer to see what it does and what sits on it.
Layer 07 · Partner-owned
Aeviva is the first platform built on Waven: its brand, membership, services and clubs are Aeviva's; the testing, modeling, intelligence and formulation underneath are Waven's. A platform starts with a measurement layer, a twin and a formulation engine already in production instead of a two-year roadmap.
Layer 06 · Surfaces
Members see their twin, BioAge, daily metrics, AI companion and formula in a branded app. Partners register chips, read results, review formulas and follow their members from a console. Everything either one shows is served from the same APIs, so a platform can build its own surfaces on them too.
Layer 05 · Formulation
Waven Dots are precisely dosed units of nutrition, organised by the sub-age they support. A member's formula is a count of dots per dimension, composed against the current twin and dispensed morning and evening by Neo. For complicated pictures, a deep pass over the whole twin authors a 28-day compounded formula that a qualified reviewer signs off before it is made.
Layer 04 · Intelligence
The companion explains what moved since the last read, in plain language, with the twin as context. The formulation engine proposes dot counts from what is actually elevated. And every proposal — human-adjusted or not — passes the same validator: a dose outside its validated range is rejected outright, never rounded to the nearest allowed value.
Layer 03 · Model
The twin is a person's whole health model, assembled from four layers: precision testing, daily monitoring, medical records and personal profile. It updates on every event, not on a monthly batch. From the biomarker panel it resolves four sub-ages — Cellular, Metabolic, Micro-Vascular and Resilience — weighted equally into one BioAge.
Layer 02 · Monitoring
Waven Halo is our own ring and band, syncing sleep stages, activity, resting heart rate, HRV, blood oxygen and an on-demand stress score. But the layer is built open: Apple Health, Garmin and Fitbit are ingested just as readily, and a photograph of a scale, cuff or glucose meter is enough for the reading to be extracted.
Layer 01 · Measurement
Each Kino Chip is single-use and registered by scanning its QR code, so a read belongs to one person before it starts. The Kino Analyzer is the reusable reader that lives at a clinic, studio or partner location and sends the result straight into the twin — a BioAge and four sub-ages, minutes after the sample. The measurement is Waven's; the location is the partner's.
§02 The Digital Twin
"Digital twin" usually means "we read your smartwatch." At Waven it has an enforced meaning: the twin is a person's entire health model, assembled from four distinct layers, and it is never any single one of them.
Kino reads, resolved into a BioAge and four sub-ages — the precise snapshot.
Sleep, activity, heart rate, HRV and blood oxygen from Halo or any wearable — plus anything entered or photographed.
Hospital reports, annual lab panels and uploaded PDFs — the history a wearable can't see and a single test can't reconstruct.
Profile, questionnaires and what the person has told the AI companion — allergies, restrictions, what they are actually trying to achieve.
Poor sleep → rising inflammation → an older Resilience Age.
The point of holding four layers in one model is being able to read a line like that across them.
What the twin deliberately does not include: plans and formulas. Those are what a person does, not what they are. Domains with no data are left out of the score rather than counted as zero.
