At Colossal Biosciences, we endeavor to jumpstart nature’s ancestral heartbeat

Texas Fund I

Colossal will revolutionize history and be the first company to use CRISPR technology successfully in the de-extinction of previously lost species. On the journey we will build radical new software tools and technologies to advance the science of genomics overall. At Colossal Biosciences, we endeavor to jumpstart nature’s ancestral heartbeat. To see the woolly mammoth thunder upon the tundra once again. To advance the economics of biology and nutrition. To make humanity more human. And to reawaken the lost wilds of Earth. So we, and our planet can breathe easier. These things, which were not achievable before, are now. In our laboratories. Through our breakthroughs in CRISPR and genetic engineering. We are leading the new charge of bioscience. We accept the responsibility. And we can see the light at the end of it all.
