Executive 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.

Dmitry Pashkevich

CTO & Principal

Dmitry formerly ran the computing center at Omsk State University in Russia, where he was surprised by the number of top engineers graduating with limited prospects in Siberia. He brought several former top students and faculty to start the Omsk branch of Thumbtack, and continues to leverage his engineering connections to bring the best and brightest to the team.

Dmitry holds a BS in Physics from Omsk State University.

Mark Leibowitz

VP of Sales

Mark has over 20 years of success selling solutions for early stage and start-up companies.

Jonathan Hansen

VP of Operations

A technologist by trade, a process maven in practice, and a team builder at heart. Jonathan is the versatile software development leader responsible for implementing and maintaining our operational core competencies and processes. He focuses on customer needs and implementing metrics to ensure daily operations meet those success requirements through predictable, repeatable performance with continuous improvements. Jonathan is a coach and evangelist of Lean & Agile Methodologies; he leads the Kanban meetup in NYC. He finds himself more productive with cold beer in hand and loves listening to jazz music (but not while he’s working, because of science).
