About Wildtype

Wildtype is on a mission to create the cleanest, most sustainable seafood on the planet, starting with sushi-grade salmon. We're pioneering cellular agriculture to protect wild species and our oceans, and to reverse trends of global food insecurity. Wildtype will provide consumers with a new option for real seafood that provides the same nutritional benefits as the most pristine wild-caught fish, without common contaminants such as mercury, microplastics, antibiotics, or pesticides.

We were founded in 2016 by Aryé Elfenbein, a cardiologist and molecular biologist, and Justin Kolbeck (CEO), a former US diplomat who served in Pakistan and Afghanistan, in an effort to solve one of the world's biggest problems: how to feed a growing population without stripping the earth of its natural resources and biodiversity. Investors include L Catterton, Jeff Bezos, Spark Capital, CRV, Temasek, Leonardo DiCaprio, and Robert Downey Jr.'s Footprint Coalition, among others. 

Come join us in transforming our food system for good!
