My first startup was a deep tech company that I started based on my MIT research. When I started that company, I transitioned from a tech role to running the other sides of a company--sales, marketing, legal, finance, etc. My most recent startup was acquired by Dropbox in 2014.
My first startup (Ksplice) developed technology that makes it possible to apply software operating system updates without needing to reboot. It won the Wall Street Journal's award for best security or privacy innovation of 2009.
