Physical sciences venture capital - imageARCH portfolio companies in the physical sciences are pioneering technology with a range of commercial applications in:

We have founded companies from the world's leading research centers in physics, mathematics, advanced materials, bioengineering, artificial intelligence, chemistry, fiber optics, and defense electronics. As in our other specializations, we are interested in breakthrough science that can be the foundations of new industries and lead the way in their respective fields.

A strong history of collaboration with the academic and research community has made us the venture capital partner of choice for innovative scientists who want partners that understand the advanced technology they are exploring. As a result, many of our portfolio companies in the physical sciences originated in laboratories at institutions such as Columbia University, Harvard University, Argonne National Laboratory, University of Washington, University of Michigan, Tufts University, Northwestern University, and Massachusetts Institute of Technology, among others.
