Side-by-side comparison of AI visibility scores, market position, and capabilities

Addition Therapeutics

EmergingBioTech

Non-Viral Gene Therapy (PRINT)

Emerged from stealth with $100M (Dec 2025) backed by Gates Foundation, SR One, Abingworth. PRINT LNP platform integrates RNA at specific genomic loci — potentially re-dosable gene therapy for rare and chronic diseases.

About

Addition Therapeutics emerged from stealth in December 2025 with $100 million in financing backed by the Gates Foundation, SR One, and Abingworth, developing PRINT — a platform using lipid nanoparticles (LNPs) to deliver RNA and enzyme payloads that integrate therapeutic sequences at specific genomic loci. Unlike traditional AAV gene therapy (which requires viral vectors and can only be dosed once due to immune response), PRINT's non-viral approach is potentially re-dosable, opening gene therapy to chronic diseases beyond rare genetic disorders.

Aerska Therapeutics

EmergingBioTech

CNS Gene Silencing (Alzheimer's / Parkinson's)

Raised $39M (Feb 2026, doubled from $21M Series A). Brain-shuttle + RNAi delivery for genetic Alzheimer's and Parkinson's. Non-viral CNS delivery crossing blood-brain barrier.

About

Aerska Therapeutics is developing a brain-shuttle RNAi (RNA interference) platform for CNS gene silencing — specifically targeting the genetic forms of Alzheimer's disease and Parkinson's disease caused by dominant mutations that can be silenced by RNA therapeutics. The company raised $39 million in February 2026, doubling its prior $21 million Series A round, led by ex-AstraZeneca neuroscience executives who validated both the science and the commercial opportunity.
