IT leadership,
exactly when
you need it.
I take responsibility for your IT – for a transition period, a critical project, or permanently one or two days a week. 25 years in IT, 16 of them as Group CIO of an international group.
When companies bring me in
Your head of IT leaves
Your IT lead quits or falls ill, the replacement takes months – and operations must keep running.
Merger, acquisition, carve-out
Two IT landscapes need to become one – or one needs to be separated cleanly.
Outdated infrastructure
Servers from 2012, grown domains, overdue migrations and nobody with the full picture.
AI without data risk
You want to use AI every day, but not hand client data to someone else's cloud.
Buying a company
Before you buy, you need an honest assessment of IT, risks and required investment.
Expensive vendors
IT partners cost a lot and deliver little, and nobody internally can manage them as an equal.
Services
Clear scope, clear price. Contracted and invoiced through SafeTech Investments AG, Zug.
Fractional CIO
Senior IT leadership one or two days a week: strategy, budget, vendors, security and reporting to management.
Interim CIO
Full IT responsibility for a transition period or a transformation programme – until a successor is in place or the goal is reached.
IT audit & due diligence
An assessment of your IT or a target company: systems, risks, costs, investment needs and a prioritised roadmap in 2–3 weeks.
Migration & private AI
Active Directory, Exchange, Microsoft 365, VMware, data-centre moves – and AI assistants running on your own servers.
Cases
Full domain migration
External IT lead: migrated an Active Directory domain into a new forest with 200 users, 30 SQL databases and two mail servers. Every server moved from 2008/2012 to Windows Server 2025, with new hardware, VMware and network. Zero data loss.
Post-merger IT integration
Merged the IT of two companies with 500 and around 1,200 employees – within one month, without data loss or business interruption.
documents leave the firm
Private AI assistant for a UK legal company on its own server in Germany: document analysis, search across internal knowledge, a Telegram bot and a voice assistant.
How I work
Remote first
Most of the work happens remotely. You save travel costs and I spend my time on the actual work.
On site when it matters
For kick-offs, workshops, go-lives and key meetings I come on site in blocks.
Clear billing
Fixed price or day rate, contract with a Swiss company. No surprises on the invoice.
Honest
If I am not the right person for your problem, I will tell you in the first call.
About me
Michael Grinman. 25 years in IT, 16 of them as Group CIO of an international group with 3,000 users, 21 offices across Europe, around 100 servers and a €500k annual IT budget.
I have integrated mergers, wound down companies, moved data centres and rebuilt infrastructures from the ground up – and I still work hands-on. Today I also build private AI assistants that run on my clients' own servers.
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.
