Fast Data Science's Clinical Trial Risk Tool for the Gates Foundation is a public deployment under an MIT license, method published in Gates Open Research, so anyone can run it. wegewerk's build for the Humanistischer Verband Berlin-Brandenburg is an LLM chatbot on the association's own editorial content; its CMS extensions for summaries, alt text, FAQs and plain-language versions install into the platforms it builds on. Transparity's custom system in production, Bordereaux Sync, was built for an insurer, Charles Taylor InsureTech; its work with RNIB, Alzheimer's Society and Aston University is Microsoft 365 Copilot adoption, not a custom build. A grant is time-boxed, so the sorting question for a development buyer is what keeps running, and at whose cost, when it ends. Open code costs nothing to keep but needs a maintainer; Fast Data Science's published strength is NLP and research-grade analysis, so ask for evidence before commissioning a production platform, and ask who does the work at that headcount. A Copilot rollout leaves licenses that renew, which Transparity also sells, so put the per-seat cost after the first phase into the budget the funder sees. A chatbot on a CMS you already pay for adds no subscription, but wegewerk's case publishes no evaluation, guardrails or outcome, and the rest of its portfolio is web and campaign work; ask to see it measured before it answers your members' questions. ## Questions buyers ask ### How many AI agencies work with nonprofit on ai development? 3 agencies in our directory combine verified nonprofit client evidence with documented AI Development work.
