The Problem

Population statistics do not
prescribe to individuals.

Current clinical tools operate on cohort averages. Kairos operates where clinical decisions actually happen — at the individual level.

Correlation masquerades as causation

Regression-based tools identify associations — they cannot tell you whether a protocol caused a biomarker shift or merely correlated with it. Dragonnet-level causal inference requires infrastructure most teams cannot build in-house.

60% response rates leave 40% behind

A protocol effective for the majority fails the outliers — often the patients with the highest unmet need. Individual treatment effect estimation identifies who responds before you commit to a 90-day protocol.

Point estimates carry false precision

A single predicted value is not actionable — it is overconfident. Calibrated conformal prediction intervals tell clinicians the range within which the true response will fall, at any requested confidence level.

Core Capabilities

Clinical ML infrastructure,
not another dashboard.

Five production models. One API surface. Designed to plug into your clinical workflow without rebuilding your data pipeline.

XGBoost + MAPIE

Risk Prediction

Five-class treatment response prediction with conformal prediction intervals. Every output includes a calibrated uncertainty range — never a bare point estimate.

T-Learner ITE

Treatment Effects

Individual treatment effect estimation via twin XGBoost T-Learner. Identifies which protocol produces a measurable response for this specific patient.

Dragonnet

Causal Inference

Deep causal model jointly estimates propensity and outcome. Separates causation from correlation in observational clinical data at scale.

19 Biomarkers

Biological Age

Composite biological age from 19 biomarkers with gender-specific calibration. Delta-age output quantifies the gap between chronological and biological age. ICC ≥ 0.75.

Bayesian Posterior

N-of-1 Learning

Bayesian posterior updates with every blood draw. Priors encode 45+ published meta-analyses. Each observation refines the patient-specific model — no retraining.

REST API

Single API Surface

All five models accessible via one authenticated REST endpoint. Structured JSON. No proprietary SDK. GCP Cloud Run. 47ms p95 latency.

Integration

From biomarker panel
to clinical decision — one call.

Ingest

Send patient biomarker data as structured JSON to a single authenticated endpoint. No proprietary SDK. No custom data pipeline. HIPAA-aware architecture.

Infer

Receive individual treatment effects, biological age, risk class, and Bayesian posterior — each with calibrated confidence intervals. Latency under 50ms at p95.

Learn

Each new observation updates the patient's Bayesian posterior automatically. Prediction accuracy improves with every blood draw. No manual retraining required.

Evidence Foundation

Built on evidence.
Updated with every observation.

Priors sourced from peer-reviewed meta-analyses. Models validated against MIDUS and NHANES cohorts. Every prediction traceable to its evidence base.

19 Biomarkers tracked
15 Treatments in registry
45+ PMID-cited priors
536 Validation tests
70+ API endpoints

Bayesian priors with provenance

Every prior in the registry is encoded with a PMID or DOI. Standard deviations are inflated 20% for conservatism.

Conformal prediction guarantees

Marginal coverage is guaranteed at the requested level without distributional assumptions. Valid on finite samples.

Cohort-calibrated correlations

Biomarker correlations and biological age slopes calibrated against MIDUS (n=7,000+) and NHANES. 20–30% real-world degradation accepted and documented.
