Your CIO.
Without the
full-time cost.
16 years leading IT for an international group. Now I help mid-sized companies and law firms run IT that is secure, modern and under their own control — remotely, one or two days a week, or for a defined project.
Four ways I can help.
Clear scope, clear price. Contracted and invoiced through SafeTech Investments AG, Switzerland.
Fractional CIO
Senior IT leadership for companies that need a CIO, but not five days a week.
- IT strategy and budget
- Vendor and contract management
- Security, audits and compliance
- 1–2 days per week, remote
IT Audit & Due Diligence
A fixed-price review of your IT — or of a company you plan to buy — with a prioritised roadmap.
- Systems, data and security risks
- Costs and investment needs
- Target picture and roadmap
- Delivered in 2–3 weeks
Migrations & Modernisation
Large, messy, business-critical migrations — planned with rollback, delivered without data loss.
- Active Directory, Exchange, Microsoft 365
- SQL Server, VMware, Windows Server 2025
- Data-centre moves
- IT integration after mergers & carve-outs
Private AI
An AI assistant for your team that runs on your own servers in Switzerland or the EU. Your data never leaves your infrastructure.
- Document analysis and search (RAG)
- Built for law firms, fiduciaries, consultancies
- Telegram, web and voice interfaces
- Setup plus monthly support
Proof, not promises.
Full domain migration & modernisation
Migrated a complete Active Directory domain into a new forest as external IT lead: 200 users, 30 SQL databases, two mail servers with 60–70 GB mailboxes. Every server upgraded from 2008/2012 to Windows Server 2025, with new hardware, VMware, network and server rooms. Zero data loss.
Post-merger IT integration
Led the IT merger of two companies with 500 and around 1,200 employees. The full infrastructure was integrated within one month, without data loss or business interruption.
Private AI assistant for a law firm
Designed and deployed an AI assistant for a UK legal company on its own server in Germany: document analysis, retrieval over internal knowledge, a Telegram bot and a voice assistant.
Group CIO, international group
IT for 3,000 users across 21 offices in Russia, the UK and France, around 100 servers and a €500k annual budget. Product owner of a vending-machine purchase app with about 4 million users. Ran the IT and legal side of winding down several UK group companies.
Michael Grinman.
IT leader with a lawyer's mind. For 16 years I ran IT for an international group — infrastructure, budgets, vendors, mergers and wind-downs — and I still work hands-on.
I also hold a law degree. It helps in projects where IT meets contracts, compliance and regulators — from vendor negotiations to M&A and data protection.
I work in German and English, contracted through SafeTech Investments AG in Zug, Switzerland. Personal website: interimcio.ch.
