Amber Bio is a San Francisco-based biotechnology company founded in 2021 that is pioneering RNA-based gene editing. Its multi-kilobase RNA writing platform is designed to correct thousands of diverse mutations across a patient population with a single product, rather than requiring an independent therapy for each separate mutation. The company positions the approach as safe (minimal off-target effects), reversible, and capable of edits far larger than conventional base or prime editing, targeting previously undruggable genetic disease populations. Amber Bio launched publicly in August 2023 with an oversubscribed $26M seed round co-led by Playground Global and Andreessen Horowitz Bio + Health. It is a pre-clinical therapeutics company and publishes no public API, developer portal, or SDK surface.
