Missed cleanings with no backup
When the previous provider’s cleaner couldn’t make it, the office simply didn’t get cleaned. No replacement, no advance notice — on Mondays, the team came in to dirty desks and full wastebaskets.
Case study · Tech & gaming · Hamburg-Wandsbek
Since August 2023, Ruiz Büroreinigung Hamburg has been cleaning the 200 m² office of game developer Crazybunch UG in Hamburg-Wandsbek — with a dedicated team of permanent employees, a strict NDA policy, and a month-to-month contract. More than three years of genuine partnership, with no subcontractors.
Key facts about the partnership
In August 2023, Ruiz Büroreinigung Hamburg took over routine janitorial cleaning for the 200 m² office of Hamburg game developer Crazybunch UG in Wandsbek. In 2026, we can look back on more than three years of continuous partnership — in an industry where service providers typically come and go.
What matters most to tech and gaming studios: high-end hardware and dev kits that stay reliably dust-free, absolute discretion about unreleased games under an NDA, and flexible cleaning after 6 p.m., outside core working hours.
In this case study, you’ll learn why Crazybunch switched providers, how our team of permanent employees looks after sensitive workstations, and why the partnership has lasted more than three years on a month-to-month contract.
The challenge
In the summer of 2023, Crazybunch’s management faced a situation many Hamburg businesses know well: their previous provider no longer delivered the reliability a growing studio needs.
When the previous provider’s cleaner couldn’t make it, the office simply didn’t get cleaned. No replacement, no advance notice — on Mondays, the team came in to dirty desks and full wastebaskets.
Every piece of feedback, from scheduling requests to specialty cleaning jobs, went through an anonymous hotline. Often, only a fraction of it reached the staff on site. The result: misunderstandings and frustration on both sides.
Instead of being able to count on a clean office, the studio had to check up on the work itself: logging problems, sending reminders, escalating. Valuable time taken away from game development — and trust that kept eroding.
Industry requirements
Gaming and software studios work with delicate, expensive hardware. To make that hardware last, keeping it dust-free is a technical necessity — and it has to go hand in hand with absolute confidentiality.
Dev kits, workstations, and multi-monitor setups are sensitive to dust — and expensive. Excess moisture or the wrong cloths put them at risk; what they need is careful dry dusting with the right tools.
Office cleaning for IT companies →Game design documents, whiteboards, storyboards — anyone who cleans a game studio sees content before it’s released. A reliable partner needs permanent staff, police clearance certificates (Führungszeugnis), and binding NDAs.
Development teams work in intense sprints and release cycles, often well beyond regular office hours. Rigid cleaning schedules get in the way — what’s called for is reliable cleaning after 6 p.m. or on weekends.
The Ruiz approach
With a dedicated core team, certified eco-friendly cleaning concentrates, and our HACCP color-coding system, we’ve kept Crazybunch’s workspace spotless for more than three years.
Full continuity and personal accountability on site:
100% our own permanent staff — 0% subcontractors
Always the same trained professionals, permanently employed under the framework collective agreement (Rahmentarifvertrag) — no rotating temps. The team knows the premises, the alarm system, and the site’s particular needs inside out.
Vacation & sick-leave cover, usually from the same team
If a team member is out, a colleague from the same team who already knows the site usually steps in. Since August 2023, there hasn’t been a single unplanned missed cleaning.
A direct line to the site manager
No anonymous service loop: CEO Malte Schmidt has the direct cell number of the site manager assigned to his office. Requests are handled right away, and nothing gets lost along the way.
Cancel monthly — no minimum term
No restrictive contracts that lock you in for 12 or 24 months. Crazybunch has stayed with us since 2023 purely by choice — a decision reconfirmed month after month.
The highest standards for workstations, hardware, and confidentiality:
NDA & confidentiality as standard
A written confidentiality agreement for every employee. Unreleased games, code, and whiteboards stay protected inside the studio.
Hardware-safe dry dusting
Workstations and IT peripherals are dusted dry and gently — no moisture near fans or cabling. That extends the life of the hardware.
HACCP-compliant four-color system
Every cleaning cloth is strictly color-coded: blue for desks, green for the kitchenette, red for restrooms. This rules out cross-contamination between areas.
Dr. Schnell eco concentrates
Only EU Ecolabel–certified concentrates from Dr. Schnell — effective against dirt, gentle on indoor air, people, and the environment.
