Chief Revenue Officer, Mitchell Plonski 

Plonski joined Shift5 in 2019 as Executive Vice President where he has been involved in every facet of the company’s go-to-market strategy and growth across commercial and federal markets. Prior to Shift5, Plonski served in the U.S. military and U.S. Intelligence Community for 13 years in numerous operations and executive management roles. His experience with government acquisition, emerging technology, cybersecurity, and acquisition reform created the base of the company’s sales strategy with the Department of Defense (DoD) and opened the doors to its commercial growth. In his role as CRO, Plonski will oversee Shift5’s revenue-generating processes across federal and commercial markets.

“My time in the military and intelligence made clear the opportunity for innovative technologies to support meaningful change within the DoD,” Plonski said. “We’re bringing new opportunities to operations and cybersecurity teams in defense, aviation, and rail to better run and defend their fleets. As a dual-use technology, the force multiplier Shift5 brings to each market is significant.”

Chief People Officer, Amanda Lampert 

Lampert, who joined Shift5 in 2021, is a former Marine Corps small unit leader, electronic warfare analyst, and disaster response professional who has led several human resources programs across industries. Her work as Shift5’s VP of People resulted in the maturation of its HR systems and processes as the company achieved 54% growth in headcount year-over-year. Lampert will be a strategic partner to the C-suite through Shift5’s next growth phase, enabling the company to embrace work reinvention in a post-COVID world.

“Supporting and enabling people to be successful has been the center of each job I’ve held, and I’ll continue to leverage my successes and learnings in this new role,” said Lampert. “The landscape for talent is competitive in the technology sector and Shift5 remains committed to being a rewarding and flexible place to work, particularly as it grows.”

Vice President of Marketing, Colby Proffitt 

Proffitt, a technology marketing expert with deep focus on messaging, positioning, and go-to-market strategy, has led global thought leadership and public sector marketing programs for several cybersecurity leaders across the industry. With roots as a consultant and analyst for multiple agencies, including the DoD, Department of State (DoS), the Business Transformation Agency (BTA), the U.S. Agency for International Development (USAID), and the U.S. Patent and Trademark Office (USPTO), Proffitt’s extensive experience and familiarity with government will bring strategic vision to Shift5’s overall go-to-market strategy. Proffitt will oversee the company’s marketing and PR team, defining and enhancing the company’s brand presence across commercial and federal markets.
