What are the aims of Colossal Biosciences?

Colossal Biosciences is a biotechnology and de-extinction company with aims to resurrect the Wooly Mammoth, Tasmanian Tiger and the Dodo. Recently Colossal Biosciences have also expressed an interest to contribute to the conservation of the Sumatran Rhino using advanced reproduction technology. Colossal Biosciences hopes to have the first wooly mammoth hybrid calves by 2027 with a plan to reintroduce them to their historical range in the Arctic Tundra.

Who are the founders of Colossal Biosciences?

Colossal Biosciences was founded by George Church and Ben Lamm in 2021. Dr. George Church is a genetics professor at Harvard Medical School, known for his pioneering work in gene editing and synthetic biology. He has co-founded several biotech companies and is renowned for his contributions to the field of genomics. Ben Lamm is a serial entrepreneur and has previously co-founded several technology companies.

How is Colossal Biosciences funded?

Colossal Biosciences recently raised $150 million led by the US Innovative Technology Fund. Much of this will go towards their new Avian Genomics Group to support their aims in bringing back the Dodo. Their previous round of funding was $50 million and was led by Thomas Tull and At One Ventures.
