Sep 2025Series CUS Innovative Technology Fund; Peter Jackson; Bob Nelsen$120M$10BColossal Biosciences, founded in 2021 by Ben Lamm, George Church, and others, and headquartered in Austin or Dallas, Texas, specializes in de-extinction and advanced genetic engineering using CRISPR, synthetic biology, and AI to revive extinct species like the woolly mammoth, dodo, thylacine, and moa, while applying technologies to conservation, genetic rescue, cloning, and human healthcare including multi-genic diseases, IVF, and drug discovery. The company achieved unicorn status in 2023 and decacorn status with recent raises. In September 2025, Colossal secured an additional $120 million in its Series C round from investors including US Innovative Technology Fund (USIT), Bob Nelsen, Peter Jackson, and Animal Capital, bringing the total Series C to $320 million after an initial $200 million tranche led by TWG Global (co-led by Mark Walter and Thomas Tull). This extension valued the company at $10.32 billion post-money, with total funding raised reaching approximately $555-568 million across rounds. The capital supports expanding infrastructure, avian genomics teams, de-extinction projects like dodo and moa, lab operations, species research, and hardware/software innovations. Colossal reports high capital efficiency at 18.51x total capital raised and significant expenses around $19 million monthly earlier in 2025, driven by salaries for 180+ scientists averaging $700,000 annually, providing less than a year's runway per $200 million tranche; no significant revenue is projected until 2027 from livestock genetics enterprise sales estimated at $15 million. Secondary market data as of early 2026 shows shares at a discount to the Series C post-money valuation, with current estimates around $10.2-10.3 billion.
Jan 2025Series CMark Walter (lead); Thomas Tull (lead); TWG Global (lead)$200M$10BColossal Biosciences, a Dallas-based biotechnology company founded in 2021, develops genetic engineering technologies to achieve de-extinction of species like the woolly mammoth, Tasmanian tiger (thylacine), and dodo bird using CRISPR, genomics, and synthetic biology. The company employs over 170 scientists across facilities in Boston, Dallas, and Melbourne, focusing on computational biology, cellular engineering, genome editing, embryology, and animal husbandry to reconstruct ancient genomes and revive extinct species. In January 2025, Colossal raised $200 million in an initial Series C funding round led by TWG Global (jointly run by Mark Walter and Thomas Tull), achieving a post-money valuation of $10.2 billion. This marked the company as Texas's first decacorn and brought total funding to $435 million since inception. The capital supports expansion of de-extinction projects, addition of new species teams, and efficiency gains through AI models and core infrastructure without significantly increasing headcount. The company remains pre-revenue, with no current income but anticipates future streams from biodiversity credits, technology licensing, and government collaborations, potentially generating billions in annual recurring revenue post-successful reintroductions expected around 2028. Progress includes highly complete ancient genomes (e.g., 99.99% for thylacine) and advancements like primordial germ cells for the dodo, accelerating timelines from 10 to 8 years for some projects. A later Series C extension in September 2025 added $120 million from investors including Peter Jackson, US Innovative Technology Fund, and Bob Nelsen, raising the round total to $320 million and valuation to $10.3 billion, with overall funding exceeding $555 million. Expenses run high at about $19 million monthly, primarily on researcher salaries, providing under a year's runway per raise.

Mar 2022Series AAt One Ventures (lead); Thomas Tull (lead); Breyer Capital; Animal Capital; Animoca Brands; Draper Associates$60M-Colossal Biosciences is a Dallas-based biotechnology company founded in 2021, specializing in genetic engineering and de-extinction technologies using CRISPR, genomics, and synthetic biology to revive extinct species like the woolly mammoth, thylacine, and dodo bird, while also developing solutions for biodiversity and climate challenges. The company raised $60 million in its Series A round in March 2022, led by Thomas Tull (CEO of Tulco) and At One Ventures, with participation from investors including Untamed Planet, Animoca Brands, Breyer Capital, Animal Capital, Arch Ventures co-founder Robert Nelsen, Bold Capital, Boost VC, Jazz Ventures, Builders VC, Green Sands Equity, Draper Associates, Charles Hoskinson, and Paris Hilton. This followed a $15 million seed round in September 2021, bringing total funding at that point to $75 million, with proceeds used to establish genetic engineering research, build core technology platforms, and hire scientific teams. The Series A aligned with Colossal's positioning at the intersection of climate science and biotech, focusing on restoring ecosystems through de-extinction and advanced biological solutions to combat climate change and pollution. Subsequent rounds included a $150 million Series B in January 2023 and a $320 million Series C in September 2025 led by TWG Global (co-led by Mark Walter and Thomas Tull), Peter Jackson, Robert Nelsen, and US Innovative Technology Fund, with the latter achieving a post-money valuation of around $10.2–$11 billion and total funding exceeding $568 million. Colossal operates labs and research partnerships in the US and internationally with academic institutions and conservation groups. It leverages multiplex gene editing for applications in therapeutics, agriculture, and industrial biotech within the growing gene editing market (projected $9.3 billion in 2024 to $40.1 billion by 2034). Through its Form Bio spinoff, it enters the bioinformatics market ($14.3 billion in 2024 to $50.3 billion by 2030). Recent initiatives include creating wolves using extinct dire wolf DNA and plans for a BioVault in Dubai's Museum of the Future to store DNA from thousands of endangered species, backed by UAE investment.
Sep 2021SeedThomas Tull (lead); Breyer Capital; At One Ventures; Animal Capital; Winklevoss Capital; Draper Associates$15M-Colossal Biosciences emerged from stealth on 13 September 2021 with a $15 million seed round led by Thomas Tull, the former chief executive of Legendary Entertainment. Breyer Capital, Draper Associates, Animal Capital, At One Ventures, Jazz Ventures, Bold Capital, Global Space Ventures, Climate Capital, Winklevoss Capital, Liquid2 Ventures, Capital Factory, First Light Capital Group, Jeff Wilke and Tony Robbins also took part. The capital was raised to fund the company's first de-extinction programme and to build out its laboratory and computational biology platform. The company was founded in 2021 by the Harvard and MIT geneticist George Church and the entrepreneur Ben Lamm, the former chief executive of Hypergiant. Colossal aims to bring woolly mammoths back by using CRISPR gene editing to modify the genomes of Asian elephants and produce elephant-mammoth hybrids. Beyond de-extinction it develops artificial wombs, stem cell lines and computational biology software intended for conservation and human healthcare applications. The company was pre-revenue at the time of the round and went on to raise a $60 million Series A the following March.
