## Our take on 2021.AI
Reviewed 2026-09-03 by Gabor Kiss against published evidence.

Four named clients show completed AI systems, not pilots: a GRACE-platform virtual assistant answering patient questions live at Rigshospitalet, a computer-vision proctoring system deployed for Prometric, a recommendation engine BetterNow expects to lift average campaign performance by about 45%, and 20-plus forecasting models that improved Maersk Tankers' freight-price accuracy by 20%.

Every one of these systems runs on 2021.AI's own GRACE platform, so the technical narrative centers on governance and deployment tooling more than on model architecture or evaluation detail—ask what sits underneath GRACE if you need that level of specificity.

The weaker fit is buyers who want a bespoke build outside 2021.AI's platform, since every published deployment runs on GRACE by design.

### Key strengths
- Client testimonials come from named executives, including Maersk Tankers' Chief Digital Officer and BetterNow's CEO, not anonymous quotes.
- The Rigshospitalet assistant explicitly uses retrieval-augmented generation over clinically approved sources, with every response logged for traceability.
- Founded in 2016 with offices across five countries and 65-plus staff, more institutional depth than a single-city boutique.

### Good to know
- Ask whether your project would run on GRACE's standard workflow or require custom architecture outside the platform.
- The 84%-auto-routed email system and its 80% time-saving figure belong to an anonymized regulatory authority—ask for a speakable reference before treating that number as typical.
- Rates aren't published on the agency's site—confirm current pricing directly rather than relying on the directory's listed range.

## Our take on Halfspace
Reviewed 2026-09-20 by Gabor Kiss against published evidence.

The Molslinjen engagement is the one to read: an arrival-forecasting and dynamic-pricing engine for a Nordic ferry operator, credited in the write-up with a DKK 22 million annual earnings increase, a 3% cut in total fuel consumption, 3.5 percentage points fewer delayed departures and 6% more available capacity per departure, with the client's CEO named and on record.

Nordisk Film Cinemas repeats the shape—a 40% cut in operating cost on its data platform, CTO quoted—and the Maersk Drilling work turned thousands of mixed safety documents into one format behind machine-learning recommendations, but no case study read here names a model, an architecture or how a delivered system is monitored afterwards, so the outcome numbers are checkable and the engineering is not.

Much of the published work stops short of a delivered system: the Novo Holdings entry reports use cases identified and a multi-year roadmap, Energinet DataHub an assessment report and quick wins, and the Jyske Bank and Per Aarsleff entries are strategy and exploration.

The weaker fit is buyers who want an independent Copenhagen firm—Accenture acquired Halfspace in March 2025 and the company joined Accenture-owned Faculty in June 2026—so settle who signs the contract, what the rate card is now, and which of the named people stay on your account.

### Key strengths
- Client executives go on record by name and title across the studies read—Molslinjen's CEO, Novo Holdings' CFO, Nordisk Film Cinemas' CTO, Energinet DataHub's VP—so references are traceable
- The team page names its scientists: Chief Scientist Pierre Pinson is an Imperial College professor and Editor-in-Chief of the International Journal of Forecasting, beside Oxford, CERN and DTU PhDs
- Third-party recognition is checkable—a 2024 Franz Edelman Award for operations research, a Børsen Gazelle growth listing and three 2024 Danish Digital Awards, with CVR 13227500 published

### Good to know
- The company page claims more than 100 AI and data projects against roughly 19 published cases—ask for the list behind the number and which of those reached production
- Published technical writing is mostly Azure and NVIDIA product explainers—ask for an engineering write-up of a delivered system if method matters to your evaluation
- No rate is published and delivery now sits inside an Accenture-owned group—ask for the rate card and set it against the European range on our rate index before scoping
