Amp names CEO

Amp, a Louisville, Colorado-based developer of artificial intelligence- (AI-) infrastructure for the waste and recycling industry, has appointed Tim Stuart, former chief operating officer for Phoenix-based Republic Services Inc., to CEO. Stuart will replace Amp Founder Matanya Horowitz, who has transitioned to the role of chief technology officer (CTO).

“I founded Amp a decade ago with a vision to change how the world manages its waste, and I’m so proud of what our team has accomplished so far,” Horowitz says. “We have category-defining technology that’s reshaping waste and recycling. Tim’s industry knowledge and experience will amplify our ability to compete as a major player in the industry, and I’m grateful to have him on board to help realize the full potential of what we’ve started.”

Stuart joined Amp’s board as the company’s first independent director in March 2024. He most recently served as executive vice president and chief operating officer for Republic Services. In that role, Amp says Stuart spearheaded the company’s adoption, implementation and scaling of new technologies while overseeing field operations, integrations and digital operations strategy and execution. Stuart worked at Republic for nearly 18 years.

Prior to Republic, Stuart spent approximately 11 years at Houston-based WM.

“The potential of meaningfully lower-cost, higher-performance recycling systems is exciting, and the ability to process municipal solid waste to further reduce environmental impact is significant,” Stuart says. “I’m impressed with everything Matanya and the Amp team have accomplished, and I’m eager to bring my deep understanding of the market to help deliver on the full potential of this technology. Matanya’s a brilliant technologist, and I look forward to continuing to work with him in his capacity as CTO to make our solutions pervasive with waste companies and municipalities.”  

Earlier this year, Amp introduced an AI-powered system to sort municipal solid waste in Portsmouth, Virginia. The company also installed an AMP One system to sort single-stream and commercial recycling in Greenville, North Carolina.
