Colossal Biosciences In Talks For Funding Round Targeting $23 Billion ValuationColossal Biosciences, the de-extinction biotech startup known for its efforts to recreate the woolly mammoth and other extinct species, is reportedly in talks to raise new funding at a valuation of roughly $23 billion–$24 billion, according to Axios. The potential raise would mark a significant jump for the five-year-old company, with investors valuing not only its genetic-engineering programs but also its broader genomics, reproductive technology, conservation, and intellectual property platform. Colossal has begun generating revenue through conservation technology sales and technology spinouts, including Astromech, an AI-driven predictive modeling company, and Form Bio, a computational biology platform, expanding its value beyond de-extinction efforts.
