The bench 6 judges, built for this category
The IT Lead v1.0
Runs IT with one colleague for a 180-person machine builder with three sites and a sales office in Poland. Is retiring the old file server and wants every account provisioned from Entra ID, team folders that stay with the company when someone leaves, an audit log they can hand to the auditor, a lost laptop wiped remotely, and a way back to the last clean state if ransomware ever encrypts a share.
The Data Protection Officer v1.0
External data protection officer for a hospital group, two care providers and a payroll bureau, where the files are patient letters and salary statements. Reads who holds the keys before the feature page, asks whether end-to-end encryption survives a share link and the office editor, and wants the subprocessor list, the storage location and the contracting entity in writing before a single folder moves.
The Architecture Practice Partner v1.0
Partner in a 25-person architecture practice in Hamburg whose CAD and BIM models run to several gigabytes each, worked on from the office, from home and on the building site. Needs files on demand so laptops do not fill up, sync that sends only what changed, a drive letter the CAD software accepts, phones that open plans offline in a basement, and structural engineers who can pick up a folder without an account.
The Tax Adviser v1.0
Runs a tax practice with eleven staff and 400 clients, bound by professional secrecy under §203 StGB. Receives receipts, payslips and annual accounts from clients who will not install anything, and sends back drafts that must not end up in a forwarded email. Needs upload links, shares with expiry and passwords, a record of who downloaded what, and a provider that cannot read the files it stores.
The Agency Producer v1.0
Producer at a 30-person video and design agency in Cologne that sends cuts, layouts and raw footage to customers every day and collects their feedback. Wants review links that play in the browser, comments on the file, transfers of 100 GB that do not stall, freelancers added for one project and removed after it, connections to Slack and the project tool, and a storage bill that does not jump when one shoot fills a terabyte.
The Skeptic v1.0
Has seen "end-to-end encrypted" on a service that switches it off for shared folders, "hosted in Germany" on storage whose accounts and support run from the US, and "lifetime" plans from a company two years old. Reads that a product is "GDPR-compliant" and asks who holds the keys, whether ten years of folders, versions and shares can be exported in a form another provider imports — and what leaving would cost.
Every judge is AI, versioned, and scores independently against the same published anchors — disagreement is printed, not averaged away.
