Step 01
Unbiased Tissue-Targeting Screen
We begin with a diverse library of candidate delivery ligands — billions of molecular variants spanning chemical space — and screen them without prior assumptions about which will home to specific tissues in vivo.
In vivo screening Unbiased library Tissue selectivity
Step 02
AI-Guided Discovery
Protein language models trained on deep sequencing datasets map sequence to function — identifying functional ligands that achieve tissue-selective enrichment from within vast, uncharted sequence space.
Protein language models Sequence-to-function AI discovery
Step 03
siRNA Payload Conjugation
Dual siRNA strands are conjugated directly to the delivery ligand, creating a programmable therapeutic capable of targeting tissues with precision in vivo — sequence-specific silencing guided by the delivery vehicle itself.
siRNA conjugation Programmable payload In vivo targeting
Step 04
Dual Biology Targeting
We leverage AI to identify gene combinations that drive the most meaningful biology — findings we validate through dual silencing in vivo, intervening at the network level for efficacy beyond single-target approaches.
Novel biology discovery In vivo validation Network intervention
Step 05
Cardiometabolic Market Opportunity
Dual-gene silencing unlocks multiple large indications across cardiometabolic disease — a >$260B total addressable market with significant unmet need in obesity, MASH, heart failure, and metabolic syndrome.
