Stem (OTCMKTS: STMH) is a technology company specializing in the design, deployment and operation of energy storage systems paired with artificial intelligence–driven software. The company’s core offering combines modular lithium-ion battery installations with its proprietary Athena platform, which analyzes historical and real-time energy data to forecast demand, optimize charge and discharge cycles and participate in wholesale and demand-response markets. By automating energy storage operations, Stem enables commercial, industrial and utility customers to reduce peak electricity costs, smooth renewable generation variability and improve grid resilience.
Stem’s business model encompasses the upfront financing, installation and ongoing management of energy storage assets on a shared-savings basis. Customers pay for storage services rather than equipment, while Stem retains ownership of the batteries and monetizes grid services and energy arbitrage opportunities. This approach lowers capital barriers to entry and aligns incentives for continuous performance improvements through software updates and advanced analytics.
Founded in 2009 and headquartered in Millbrae, California, Stem has expanded its footprint across North America and into the Asia-Pacific region, including projects in Australia and New Zealand. Over the past decade, the company has collaborated with utilities, renewable energy developers and large energy consumers to deploy systems that support peak-load reduction, renewable integration and frequency regulation. Stem’s flexible platform can be tailored to a wide range of behind-the-meter and front-of-the-meter applications.
Under the leadership of founder and CEO John Carrington, Stem’s executive team brings together veterans of the energy, software and finance sectors. The company continues to pursue partnerships with grid operators and commercial energy users to scale its AI-enabled storage solutions and advance the adoption of clean, resilient energy infrastructure.
