Pioneers of mobile construction documentation. Since 2009.
Take back control of your construction phase.
The platform for the construction phase: defects, photos, site diary and 360° documentation — evidence-grade, mobile and from a single source. From the first site walk to the end of the warranty period.
- Scales with every project — from a single-family home to major projects with 100,000+ defects [BELEG: Projekt + Zahl verifizieren]
- Millions of images from real construction sites [BELEG]
- Software + hardware from a single source
In use at companies that have to prove their quality:
You are liable for what happens on the construction site. We make sure you can prove it.
Notes, photos, Excel — scattered everywhere.
Defects on slips of paper, photos on three phones, lists in five versions. With OX, everything ends up in one place: the project.
Deadlines nobody tracks.
Rectification deadlines slip by unnoticed — until it gets expensive. OX monitors every deadline automatically and speaks up before things get critical.
Missing evidence in a dispute.
Years after acceptance, the one photo you need is missing. With complete, time-stamped documentation you win the argument before it ends up in court.
Your digital toolbox for the construction phase
Five tools, one project, no duplicate data entry — each module strong on its own, unbeatable together.
Software and hardware. One project.
Five apps and five hardware building blocks work hand in hand: everything recorded or captured on the construction site automatically ends up in the same project — located, dated, evidence-grade.
Software + hardware. From a single source.
The construction site that documents itself.
Software can only document what someone records. That is why we also build the hardware: the DIGIBAU 360 360° helmet camera captures every walkthrough in full. The Bau-Webcam records progress around the clock. The Bau-Drohne delivers the bird's-eye view, Bau-Wetter the weather data for the site diary — and everything ends up in your project automatically.
No other provider in the competitive field delivers software and its own construction site hardware from a single source. [BELEG: Wettbewerbsanalyse 27.07.2026, Konzept Abschnitt 13]

AI-generated 
AI that works only with your project data. AI
Our image AI comes from our own research (BMBF project ESKIMO, trained on more than 200,000 real construction site images): it turns photos into ready-made defects, detects work progress and pixelates people automatically — GDPR-compliant, servers located in Germany. No gimmick: less typing, faster reports, cleaner documentation.

Image → defect
Take a photo — the AI recognizes the construction defect and creates it in structured form, ready to assign. [BELEG: Funktionsumfang gegen OX-Hilfe abgleichen]
Dictate daily site reports instead of typing
The AI assistant transfers your input into the familiar report template and writes a clear, professional text.
Detect work progress automatically
From construction site photos and 360° walkthroughs — target-versus-actual comparison at every spot on the site. [BELEG: Funktionsumfang gegen OX-Hilfe abgleichen]
DIGISCHUTZ
People and faces pixelated automatically — plus detection of laser distance meters and construction objects.
For everyone who carries responsibility on the construction site

Contractors
Work off defects, prove your work — with free accounts.
More than software: service and process that carry you.
Digitalisation rarely fails because of technology — it fails on process. That's why we deliver both.
Personal onboarding
We accompany your start in person — from the first project to a well-oiled process. [BELEG: typische Onboarding-Dauer]
Support from Karlsruhe
Short paths, real people: our support team sits in Karlsruhe — no anonymous queue.
Construction process know-how
We digitalise your existing defect and acceptance process instead of forcing a foreign one on you.
Live every two weeks
Free webinars with real use cases — 45 minutes, no sales show.
What the people who use it every day say
For us, the current challenges of LPh 8 are no longer conceivable without the services of Open Experience. Acceptance inspections, report included, now take only a fraction of the time.

Frequently asked questions
What does Open Experience do?
Open Experience is the platform for the construction phase: software for defect management, construction documentation, site diary, checklists and deadline tracking — plus its own construction site hardware such as the DIGIBAU 360 360° helmet camera. Everything from a single source, developed and hosted in Germany.
Who is the platform for?
For everyone responsible for construction execution: site managers and senior site managers at general contractors, project controllers, architects and specialist planners in site supervision (LPh 8), the housing industry and contractors — on projects of any size.
Which problems does the platform solve?
Scattered documentation, deadlines that slip by unnoticed and missing evidence in a dispute. OX bundles defects, photos, reports and deadlines in one project — time-stamped, traceable, evidence-grade.
Is the documentation legally sound?
The documentation is complete, time-stamped and traceable to the person — the basis that courts and experts expect. [JURISTISCHE PRÜFUNG: Formulierung „rechtssicher" vs. „beweissicher" final abstimmen]
Can several parties work at the same time?
Yes. All project parties work in parallel in the same project, and you assign permissions by role. Subcontractors get free accounts for defect processing.
Does it work on mobile and offline too?
Yes — apps for Apple and Android tablets and smartphones plus a browser version, with an offline mode for the relevant areas (even a basement with no signal is no obstacle).
Where is my data stored?
Servers located in Germany, GDPR-compliant processing, daily backups — made & hosted in Germany.
What does Open Experience cost?
Three transparent packages, publicly available at /en/preise/ — no hidden costs, no fees per plan or model, no limits on images or items [BELEG], free accounts for subcontractors included.
How quickly are we up and running?
A new project is set up in a few minutes; we guide the rollout personally. [BELEG: typische Onboarding-Dauer]
Is there a free trial?
We show you the platform in a personal demo on your own use case — faster and more honest than weeks of trying it out on your own.
In 45 minutes you will know whether OX fits your project.
