Tomorrow is Grown here


Doing things differently since 1999.

The story of Medicago is rooted in a long track record of innovation and perseverance. Even our company name – the Latin word for alfalfa, which was the first plant we worked with – embodies our culture of adaptation. We're proud of our humble beginnings as much as we are of our current growth and global reach. We understand better than most that the path to success in not a straight line.

As a pioneer of plant-based transient expression and manufacturing, Medicago has always sought a more effective way to improve human health. With nearly 20 years of experience and wisdom behind us, we are ready to disrupt the traditional approach to vaccines and therapeutics.

Medicago has been privately held since 2013.

Here is a quick look at some of the key events and milestones that have helped shape the company as we exist today.
