Series B · $180M

Programmable longevity, engineered at cellular resolution.

We build gene circuits that clear senescent cells on a schedule. Fourteen candidate payloads are in vivo across three murine cohorts, with median lifespan extension of 42.8% and no observed off-target toxicity.

PLATFORM

A closed loop from construct to biological age.

Design, express, assay, re-rank — the loop closes in 11 days. Click a step, or keep scrolling.

01 / 03

Circuit design

Promoter–payload pairs are composed in silico, then ranked by predicted senolytic selectivity.

14 candidates ranked
02 / 03

Automated assay

Every candidate runs the same cytometry and qPCR battery, no manual curation.

Epigenetic readout

Methylation clocks read biological age directly, so efficacy is measured, not inferred.

MECHANISM · AG-118

The circuit sits dormant inside the cell.

AG-118 is delivered as a silent construct. In a healthy cell the promoter never fires — the payload stays inert and the cell is left untouched.
