Amp Robotics Secures $91M to Revolutionize Trash Sorting

Amp Robotics, a company specializing in the development of trash sorting robots and recycling facilities, has successfully raised $91 million in a Series D funding round. This round, concluded on November 21, was led by Congruent Ventures and included participation from Liberty Mutual Investments, the California State Teachers Retirement System, and other existing investors such as Sequoia Capital and Wellington Management. The funding mirrors the company's previous $91 million Series C in 2022. Amp Robotics initially started by creating robotic arms and AI software to enhance waste sorting efficiency. The company has now shifted its focus to building and operating entire sorting facilities, which significantly contributes to its revenue. These facilities are operational in Ohio, North Carolina, and Virginia, with a new one being commissioned in Colorado. Amp's business model primarily revolves around charging a per ton sorting fee, dubbed 'sortation as a service,' which offers enhanced material recovery and reduces worker exposure to hazardous conditions. The new CEO, Tim Stuart, previously served as COO of Republic Services, indicating a strategic leadership change aimed at further expanding Amp's influence in the waste management industry.
