Amber Bio is a San Francisco biotechnology company developing an RNA-based gene-editing platform capable of making multi-kilobase edits — rewriting thousands of bases on a single RNA strand in one step — to reach previously undruggable patient populations. Because edited RNA eventually degrades in the body, the approach is designed to be safer and reversible compared with permanent DNA editing. The platform pairs multi-kilobase RNA writing with AI foundation models to target diverse pathogenic variants across patients with a single product, initially focused on ophthalmology and central nervous system diseases. Founded by CRISPR-field researchers from the Broad Institute and UC Berkeley (co-founder and CTO Basem Al-Shayeb, advised by Nobel Laureate Jennifer Doudna), Amber Bio launched in 2023 with a $26M seed round co-led by Playground Global and Andreessen Horowitz. It has no public developer API; this API Evangelist profile tracks the company as a portfolio lead.
