About this list
Software products bought by public institutions carry a constraint ordinary SaaS does not: the buyer usually needs to know where the model runs and what happens to the data. The work documented here reflects that. Babelscape's TraDeInterpret is a SaaS multilingual analyzer built for EUIPO, the EU's intellectual property office, working across 23 official languages on the firm's own knowledge graph. Hybrid Heroes builds consumer-grade software for institutions—the rbb24 app for the Berlin-Brandenburg public broadcaster, rated 4.6 across more than 10,000 reviews, and an e-mental-health platform with Freie Universität Berlin and the Swiss Red Cross. DataNorth AI works the Dutch public sector through both delivery and enablement, mapping 55 actionable use cases across Omrin's waste-management operations and running AI skills programs for Divosa, the association of municipal social-services directors.
Two things make this a distinct purchase. Public bodies buy capability as much as software, so an engagement that leaves nobody internally able to run the thing has failed on a criterion the contract may never have named. And procurement timelines outlast model generations, so ask what happens when the underlying model is deprecated mid-contract and who pays for the migration. DataNorth publishes its rates, which is rare enough here to be worth using as a benchmark for the others.
Expert Insight
Why SaaS & B2B experience matters
Evaluation infrastructure—The difference between a demo and a durable feature is an eval suite: test sets, regression checks on prompt changes, quality metrics tied to user outcomes. Specialists build it alongside the feature; without it, every model update is a gamble shipped straight to production
Unit-economics engineering—Per-request model costs decide whether your feature has a margin. Specialists design cost ceilings in from the start—model routing, caching, context trimming—instead of discovering at scale that the assistant costs more than the seat
Handover quality—Your engineers inherit this code. Specialists deliver documented pipelines, reproducible evals, and infrastructure your team can run; agency-shaped black boxes turn into unmaintainable dependencies the day the contract ends
Product-not-project thinking—AI features need iteration loops after launch: feedback capture, failure review, prompt and model updates. Specialists set up that loop and a sane retainer for it; project shops ship the feature and leave you with version one forever
