Co-founder & CEO

Josh started working for the DoD in high school and spent 10 years engaged in various offensive cyber initiatives and red teaming in the private sector. Phishing was always the fastest way for him to gain access to a network. He started Sublime to build a product that would stop him. Josh holds a B.S. in Computer Science from the University of Maryland. He lives in Washington, D.C. and enjoys weight lifting and spending time with family.
