Green River builds custom software to help our clients make effective, positive change in the world.

What We Do

Green River builds software for sustainability, environmental protection, school improvement, and public health. We are a full service web development shop, with a strong background in data science and analytics, and can bring the benefits of applied machine learning to your project.

We specialize in helping start-ups, as well as established organizations wanting to bring new concepts to reality. Our experience, nimble development methodology, and enthusiasm make us an ideal partner for bringing your dream into being. We have an intuitive sense (supported by data) of “what works” in both technology and organization development, and relish engineering elegant systems to achieve your goals. We are firmly committed to the environment and social justice, and see our clients as genuine collaborative partners in making the world a better place.

Sustainability & Environmental Protection

We design and construct systems for supply chain certification, generating sustainability metrics, and in support of environmental equity. We speak the language of standards and ratings, including LEED, GRESB, GRI, Fair Trade, ISO, B Corporation, CAFE Practices, KEYS, and SAI. And we provide tools to prove data collected under the auspices of corporate social responsibility can often be financially critical to an organization’s larger mission.

School Improvement & Education

We build systems for public school improvement and advocating educational opportunities. Professional development assessment, resource allocation modeling, and highly customized interactive evaluation rubrics to effect change are mechanisms we understand. We also don’t neglect actual student engagement, and create custom learning applications for outside and inside the classroom.

Public Health

We develop applications supporting individual health and fitness, create public health equity indices, and perform comprehensive statistical analysis and reporting on publicly available and private health (most often for government agencies). We navigate public disclosure regulation, and obtain third-party HIPAA compliance audits when necessary.

Data Science

We bring our analytic capabilities to projects in many domains, providing business intelligence, recommendation engines, data visualizations, and machine learning algorithms in a wide range of applications.
