Recreate human biology, computationally.

Absentia builds predictive models of living systems — computational organisms that predict how the body will respond before any experiment is run. We begin with the organ that decides the fate of most medicines.

The thesis

Prediction is the compression of time.
What becomes predictable becomes engineerable. Computation turns the unknowable into the predictable. Every domain we have made computable has become a domain we can engineer.

The Problem

We start with drug testing.

We start with drug testing.

A medicine must do two things: be safe and effective. For centuries we have relied on animal models to answer those questions. We build AI better representative of human biology — to replace animal experiments.

$2B

Cost per drug

Average cost to bring a single new drug to market.

90%

Never approved

Of candidates that enter Phase I, the share that never reach approval.

Root causes

Lack of efficacy and unforeseen safety — both failures of prediction.

Approach

Mechanistic mapping and learning, in one model.

Mechanistic mapping and learning, in one model.

A multimodal foundation model trained on vast biological data, with robust uncertainty — that learns and explains the mechanism behind every prediction.

ARCHITECTURE

Mechanism meets machine learning

A causal backbone grounds the model in biology; a data-driven layer learns what the rules can't yet describe; and calibrated uncertainty makes every prediction interpretable — down to the individual patient.

Mechanism

A causal backbone

Grounded in the biology of how injury actually occurs.

Learning

A data-driven layer

Learns the patterns mechanism alone can't capture.

Precision

For individual patients

Calibrated uncertainty, tuned to person and context.

Applications

The AI-driven Digital Liver.

The AI-driven Digital Liver.

The liver is the body's chemical interface — the first-pass filter for nearly everything we ingest, and the organ most often behind a withdrawn drug.

PREDICTIons

When will the liver be injured?

For a given molecule and context, the Digital Liver predicts the conditions under which the liver is injured — combinatorial risk that no animal or simple lab model can catch.

Safety intelligence, modernized.

Multi-endpoint optimization with supported evidence — extending beyond the liver to cardiotoxicity, renal toxicity, and more.

FDA ISTAND

Regulatory milestone

Accepted into the FDA's ISTAND program to help predict drug-induced liver injury — the first in-silico tool of its kind that regulators and drug developers can rely on during development.

Impact

Higher confidence. Faster decisions. Lower cost. Unlimited scale.
