Marshall is co-founder of Upstream. Upstream provides services to monitor and measure natural resources for efficient project implementation, via an easy to use, cohesive dashboard.
After gaining a broad set of technical and product experience working at Microsoft, Twitter, Drift (business customer communication), and Wistia (analytics visualizations), Marshall (along with his best friend and longtime colleague, Alden) started public benefit corporation Upstream with the broad goal to use technology to help the environment, particularly the underserved water space.
Using satellite imagery, environmental datasets, and machine learning, Upstream is now powering decision making at The Nature Conservancy, The National Fish and Wildlife Foundation and The Freshwater Trust.
Upstream was acquired by Natel Energy, where it will operate as an independent unit with ample funding to grow its team and broaden its impact.
