The first thing we noticed when we spoke to Tim Stuart for our latest episode of Humans Who Build was his calm and clarity of thought.That clarity reflected in his customer understanding, which led Dennis Bagley and his team at SPSA to partner with Tim's team at AMP. In November 2025, SPSA signed a 20-year agreement with AMP to scale automated waste processing to 540,000 tons annually by 2029. In the last episode, we discussed how the government decides who and how to partner with a new technology company. In this episode, we get the opposite side of things to prep for working with the government and scaling a small pilot to a 20-year agreement with a public authority (SPSA), a project designed to reach 540k tons of annual processing capacity by 2029. AMP is a waste-technology company using AI, robotics, and automated sortation systems to reduce labor costs, increase resource recovery, and deliver more reliable operations. It is backed by Sequoia Capital, Congruent Ventures, California State Teachers Retirement, among many others.Tim brings a particularly relevant perspective to these questions. Before joining AMP, he spent nearly 18 years at Republic Services, ultimately serving as Executive Vice President and COO. There, he led the adoption, implementation, and scaling of new technologies across a large operating network, while overseeing field operations, integrations, and digital operations strategy. Prior to Republic, Stuart spent approximately 11 years at Waste Management, IncIn this episode, we will learn:1. SPSA deal architecture: Scalability, risk, and execution capacity.2. Scaling technology inside a large enterprise: Lessons from Republic and AMP.3. AMP’s evolution from a robotics vendor to an operating company: The importance of long-term ownership and accountability.4. Underwriting risk as a hardware company and sharing it with partners: Technology, construction, operations, and performance risks.5. Funding the growth of a hardware company: Cash Flow from Operations vs. Fundraising.6. Building execution capacity across multiple large projects: Managing attention, capital, and operational resources.This episode is part of our Humans Who Build x Robots for America series, where we speak with robotics companies and their customers about what it takes to move industrial automation beyond pilots and into scaled deployment.Link in comments.#hardware #scale #government #robotics #roi
