Real projects. Measurable results.
Four cases across four industries. No marketing stories. Just the problem, the solution and the result.
Property manager, Amsterdam
2 weeksA property manager in Amsterdam with 180 units was spending 3 to 4 hours per day answering tenant emails. Maintenance requests, rent questions, contracts, keys. The same questions, every day, all handled manually.
We built an AI platform that analyses incoming emails, answers routine questions with information from the management system, and flags complex cases for manual handling. Maintenance requests are logged automatically.
90% of incoming emails handled automatically. Owner saves 15 hours per week. Tenants get a response within 5 minutes instead of 24 hours. No complaints about the AI responses.
“I was sceptical about AI. But within two weeks it worked, and nobody notices it is AI. I now have time for the questions that actually need my attention.”
Forensic firm
10 daysA forensic firm needed to analyse hundreds of pages of documents per case to find relevant passages. The work was time-consuming, repetitive and required extreme focus. Court deadlines were a constant pressure.
We built an AI document analysis system that searches PDFs for relevant passages, extracts citable fragments, and produces a court-ready summary with source references. Fully integrated with their existing case management.
A 48-hour deadline was met where two weeks would normally be needed. The output was used directly in court proceedings. The system has been used on every case since.
“We had tried to automate this ourselves with standard tools. It didn't work. The 425 Group team understood what we needed within an hour and delivered in ten days.”
Family business, manufacturing
2 weeksA family-owned manufacturing company had been running on dozens of Excel files for years. Orders, production, inventory and reporting all lived in spreadsheets. No oversight, errors crept in, and nobody really knew how the business was doing.
An operational platform replacing all spreadsheets. Orders, production, inventory and reporting in one system. AI generates weekly management reports. Integrated with their existing accounting software.
Full adoption within 2 weeks. Not a single Excel file still in use. The director now has a weekly real-time picture of operations instead of a monthly estimate.
“We are a fifty-year-old family business. We had no internal IT. The 425 Group team built the system and trained our people in two weeks. I didn't think that was possible.”
Freelancer accounting platform
6 weeksExisting accounting software for freelancers is complex, expensive and built for accountants. The founder wanted something that actually works for freelancers: simple, AI-powered and generating revenue from day one.
Klaro Finance, a SaaS accounting platform where AI does the hard parts: auto-categorising invoices, suggesting VAT filings, recognising expenses from receipts. Built on Next.js and Supabase, with Claude as the AI layer and Stripe for subscriptions.
Live within 6 weeks. Paying users from the first week. Since then, developed into a full platform with hundreds of active users.
“Two other firms said this would take at least six months. The 425 Group did it in six weeks, and it worked from day one. That made the difference between an idea and a business.”
