Management Team
Ben Engber
CEO, Founder
Ben has made a career around building highly reliable internet-scale applications. Prior to founding Thumbtack in 2003 he was VP of Operations Technology at GiftCertificates.com, where he built the back-office and e-commerce architectures needed to support millions of digital and physical transactions per day. During his tenure he became acutely aware of the need for outsourced labor that could both understand core business concerns and drive high-quality and robust software infrastructure projects. His inability to find such a partner led him to establish Thumbtack.
Ben holds a BS in Mathematics from the University of Chicago and a MBA from Boston University.
