What Green Stream does
Green Stream Technologies, Inc. is a privately held IoT environmental monitoring company founded in 2017 in Norfolk, Virginia by Jim Gray and Karen Lindquist, now headquartered in Wake Forest, North Carolina. The company builds end-to-end real-time flood and weather monitoring systems combining proprietary hardware (non-contact ultrasonic/radar water level sensors, precipitation sensors, weather stations, and flexible mounting systems), proprietary Corbo Environmental Transceivers (LTE cellular, Iridium satellite, and GOES satellite variants) with multi-carrier failover and datalogger buffering, and a SOC 2 Type II certified cloud platform hosted on AWS that delivers real-time dashboards, APIs, threshold alerts, and integrations with NOAA's National Water Prediction Model, National Weather Service, VDEM, and Waze. Its primary customers are state and local government agencies, including emergency management departments (VDEM, NCEM), county governments (Botetourt, Wake, Dorchester), regional planning commissions (HRPDC), and coastal observing nonprofits (SECOORA, NERACOOS), with secondary use in dam monitoring, stormwater management, and academic research.
The company operates a three-stream revenue model: hardware sales (sensors, telemetry, mounts, power systems), recurring cloud platform subscriptions with tiered plans, and professional services organized into Develop, Design, Deploy, and Defend phases covering site assessment, installation, and ongoing maintenance. Pricing is quote-based with multi-year contract cadence, and sales are frequently tied to grant funding vehicles such as the Community Flood Preparedness Fund. Distribution is direct field sales supplemented by regional planning organization channel partners, with field service operations from Wake Forest, NC and Norfolk, VA.
Green Stream has reached over 450 active deployments across 8 states as of June 2026, has accumulated woman-owned certifications (NC HUB, VA SWaM) that confer set-aside government procurement advantages, and is differentiated competitively by its SOC 2 Type II and COV RAMP certified cloud platform and its three-way strategic partnership with FloodMapp and The Warn Room for bundled observe-predict-warn flood resilience solutions.
