Founding Story
Brent Frei is a fiercely visionary American software engineer, highly strategic technology entrepreneur, and the profoundly influential CEO and co-founder fundamentally responsible for architecting the massively dominant Smartsheet cloud collaboration empire. Operating as the incredibly successful former CEO and founder of Onyx Software, Frei aggressively recognized the massive, agonizingly chaotic friction involved in tracking complex corporate projects across highly fragmented, legacy spreadsheet applications. In 2005, he relentlessly partnered with Mark Mader, Eric Browne, and John Creason to completely launch Smartsheet. By fiercely engineering a highly intuitive, massively scalable grid-based interface that completely automated complex workflows and seamlessly integrated massive corporate databases, his absolutely rigorous strategic leadership completely revolutionized global project management. His massive corporate execution permanently established Smartsheet as an absolute multi-billion dollar SaaS monopoly.
