Our story

AOSense was formed in 2004 by Brenton Young and Mark Kasevich to spin off innovative research developed at Stanford University, joined by Jim Spilker as Chairman. In 2006, AOSense was awarded its first prime contract from DARPA to design, build, and test a gravity gradiometer and single-axis accelerometer/gyroscope. Since then, AOSense has successfully designed and built state-of-the-art cold atom technology for numerous government-sponsored programs funded by DARPA, Air Force, Army, Navy, NASA, NSF, DTRA, and the intelligence community.
