Colossal Biosciences, a Dallas-based biotech company, has raised $120 million in Series B funding to accelerate its mission of de-extinction, including bringing back the dodo bird. With total funding now exceeding $225 million and a valuation above $10 billion, Colossal is redefining how synthetic biology and genomics can transform conservation.
Founders: Ben Lamm (serial entrepreneur) and George Church (Harvard geneticist)
Mission: Use synthetic biology and genomic science to revive extinct species such as the woolly mammoth, Tasmanian tiger, and now the dodo bird.
Valuation: Over $10 billion as of the latest funding round.
Challenge: Birds cannot be cloned using mammalian techniques.
Breakthrough: Colossal’s researchers successfully cultured primordial germ cells (PGCs) from pigeons.
Approach:
Genetically edit PGCs
Implant them into surrogate birds
Develop viable offspring with dodo-specific traits
Closest living relative: The Nicobar pigeon, used as the genetic foundation for the project.
Mauritius Dodo Advisory Committee: Partnership with conservationists, scientists, and government officials to guide ecological responsibility in reintroduction plans.
Conservation Tech: Applying genomic tools not just for de-extinction, but also for protecting endangered species through reproductive and genetic innovation.
Series B Raised: $120 million
Total Funding: $225+ million
Key Investors: Life sciences, AI, and sustainability backers
Use of Funds:
Scale avian genome engineering
Expand research infrastructure
Build global partnerships
Ben Lamm, CEO of Colossal:
“De-extinction isn’t about science fiction; it’s about ecological restoration and future-proofing biodiversity.”
Over $225 million, including $120M in Series B.
Projects include the woolly mammoth, Tasmanian tiger, and the dodo bird.
Birds cannot be cloned; instead, Colossal uses genetically edited germ cells implanted into surrogate birds.
Beyond de-extinction, Colossal’s technology supports conservation of endangered species and biodiversity restoration.
Colossal Biosciences’ $120 million raise signals both scientific momentum and investor confidence in de-extinction. The potential return of the dodo is more than symbolic, it marks a new era where biotechnology bridges extinction and survival, reshaping humanity’s role in ecological responsibility.
