Employment Type


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 (Chief Scientist), 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 Spark Capital, Charles River Ventures, Root Ventures, Alexis Ohanian and Kyle Vogt, among others.

Come join us in transforming our food system for good!
