About Us

Michael founded Sedoha to close a loop that has been broken for decades: the distance between measuring impact and actually improving it. He is a context engineer and public-health informaticist who has spent 25 years building continuous-improvement systems for governments, supply chains, and social-service agencies.

In 2000 he founded Green River, a software company he grew to 45 designers and engineers without outside investment. Its work includes Open Path, the open-source homeless-services data platform begun with the City of Boston and now matching people to housing for agencies across the country; My Healthy Community, Delaware’s neighborhood-level population-health platform, peer-reviewed in the Delaware Journal of Public Health; farm-inspection and worker-safety systems for Starbucks’ coffee and cocoa supply chains; and the platform behind GRESB, the global benchmark for real-estate sustainability.

In 2024 he transitioned Green River to full employee ownership through an ESOP-cooperative hybrid. He holds a PhD in Environmental Health Sciences from Yale and lives in Guilford, Vermont, where he serves on the town Planning Commission and the boards of community organizations.

For over a decade, Karim worked with UN agencies, nonprofits, foundations, and international development organizations, using digital technology to open economic opportunity for marginalized communities, including refugees. He founded SkillLab, a social venture whose AI skills-mapping platform reached workers in more than twenty countries.

Across that work, one problem kept recurring: the people deciding what counts as impact are rarely the ones closest to it. He leads impact and engagement at Sedoha to close that gap, putting social and environmental outcomes on books the people closest to the work can read and challenge, the way financial statements already work for money. He holds an MA from Johns Hopkins SAIS and degrees in engineering from Tufts and the Technical University of Munich.
