Slipstream

What Slipstream does

Slipstream is a Madison, Wisconsin-headquartered nonprofit organization founded in 1978 that designs, tests, delivers, and scales energy efficiency and renewable energy programs across the United States. With 101–250 employees and operations spanning 22 states, the organization serves three primary customer segments: utilities and energy providers (e.g., CenterPoint Energy, Consumers Energy, ComEd, Xcel Energy, Focus on Energy); state and local government agencies (e.g., the U.S. Department of Energy, NYSERDA, City of Chicago, City of Milwaukee); and building professionals plus end homeowners through workforce training and consumer resources.

The organization operates across three integrated product lines: (1) Climate + Energy Solutions, including High Performance Buildings, Resilient Communities, Grid-Interactive Efficient Buildings, and Energy Innovation programs; (2) Education to Empower the Clean Energy Workforce, anchored by the Slipstream U on-demand learning portal, continuing education courses accredited with RESNET/BPI/IREC/USGBC, the DOE-recognized Energy Skilled heat pump contractor training program, and a 16-video smart-building curriculum; and (3) Energy Finance Solutions (EFS), a clean energy lending division that has facilitated over $1 billion in loans across 92,000+ households using on-bill financing, on-bill repayment, and direct bill structures, supported by the proprietary VelocityGO cloud-based loan origination system.

Revenue mechanics rest on three streams: government grants (primarily DOE), utility program administration contracts (managed services), and EFS lending program fees (transaction-based). Slipstream does not publicly disclose revenue figures. The GTM motion is institutional and relationship-driven, with deep utility and regulatory channel partnerships rather than direct consumer sales. Notable technology investments include an open-source Wi-Fi occupancy sensing algorithm integrated with the VOLTTRON platform, and the HyGCHP hybrid geothermal heat pump modeling tool, both reflecting the organization's building-science R&D orientation rather than commercial product commercialization.
