Fast Data Science's Clinical Trial Risk Tool for the Bill and Melinda Gates Foundation extracts sample size, phase, effect size and analysis-plan presence from trial protocols; it is deployed publicly, MIT-licensed and written up in Gates Open Research. Its Harmony tool for the Wellcome Trust was entered for the Wellcome Data Prize in Mental Health. Transparity's charity work is Microsoft 365 Copilot adoption: RNIB went from 30 to 300 licenses with up to four hours a week saved per user, and Alzheimer's Society announced a first-phase rollout to 1,800 colleagues in September 2026. wegewerk advises civil-society organizations it builds websites for, foodwatch since 2015; its documented AI engagement is an LLM chatbot on the Humanistischer Verband Berlin-Brandenburg's editorial content. For a grant-accountable buyer the sorting question is what the advice leaves on the record for the funder. Fast Data Science leaves a published method and open code a review panel can read, though none of its case studies publishes an outcome number, so ask what changed after delivery. Transparity leaves an adoption report; the 1,900% return on the RNIB study has no stated method, and the firm resells Microsoft licensing, so ask how the scope changes if licenses are bought elsewhere. wegewerk's chatbot case names the model type but no evaluation or guardrails; ask how it is measured in production before a grant report has to say so. ## Questions buyers ask ### How many AI agencies work with nonprofit on ai consulting? 3 agencies in our directory combine verified nonprofit client evidence with documented AI Consulting work.
