Fractional CTO & AI Adviser

Technology that feels
personal, intelligent

Technology handled. Completely. Discreet, senior-level expertise for founders, investors, and family offices — without the overhead of a full-time hire.

A very specific clientele

Built for those who run businesses 24 hours a day, travel the world, and have no time for technology that doesn’t simply work.

Family Offices

Multi-entity structures requiring discreet, secure, always-on technology leadership across jurisdictions.

Founders & CEOs

Scaling businesses where technology decisions are business decisions — and getting them wrong is expensive.

Partners & MDs

Professional services leaders who need a trusted technology voice in the room, not a helpdesk ticket.

International Operators

Businesses operating across London, Paris, Monaco, and Dubai who need consistent, secure technology wherever they are in the world.

About Asif

Technology is about
people, not machines.

I founded SAR Computing over 20 years ago with one belief: businesses shouldn’t need to think about their technology. It should work, stay secure, and move with them as they grow.

Today I work as a Fractional CTO and AI Adviser for a select group of founders, family offices, and business leaders operating from London, Paris, Monaco, and Dubai — and available globally — helping non-technical principals make confident technology decisions without the cost of a full-time hire.

My clients share one thing: they run demanding, high-value businesses and have no tolerance for technology that slows them down, exposes them to risk, or simply doesn’t work when they need it most.

“Technology should feel like a digital butler who knows what you need before you ask.”
Best CEO Award — SAR Computing

What I do

Senior technology expertise,
on your terms.

01

AI Strategy & Adoption

Cutting through the hype to identify exactly where AI saves your business time and money — then implementing it safely, with your team and data protected throughout.

02

M365 & Cybersecurity

Most M365 environments are misconfigured and under-secured. I audit, harden, and manage your setup so it protects rather than exposes your business.

03

Digital Transformation

Moving your business from reactive to predictive — replacing manual processes with intelligent workflows that scale without adding headcount.

04

Technology Roadmapping

A clear, prioritised plan for your technology investment — so you spend where it matters and stop paying for tools that duplicate or underserve your needs.

05

Vendor & Due Diligence

Independent advice on technology procurement — from software selection to supplier contracts — with no affiliation to any vendor or platform.

06

Private AI Environments

Bespoke AI deployments for compliance-sensitive businesses — private LLM setups, RAG environments, and AI copilots that keep your data entirely within your control.

100% Discreet

Why you won’t find
logos or testimonials
on this website.

Trust is built on confidentiality. Many of my clients prefer to remain entirely private — which is why you will not find public case studies, client logos or testimonials here.

The founders, family offices and businesses I support trust me with sensitive technology, security and operational matters. Protecting their privacy is not a policy — it is a core part of the service.

Every engagement is protected by appropriate confidentiality agreements. What happens in an engagement stays there.

How it works

From first conversation
to first outcome.

01

A direct conversation

No pitch, no presentation. We talk about where your business is, where you want it to go, and whether there’s a genuine fit. I only take on clients I can meaningfully help.

02

Complimentary technology review

Before any engagement begins I conduct a thorough review of your technology setup — M365 configuration, security posture, AI readiness, and quick wins. You keep this regardless of whether we proceed.

03

A tailored proposal

I recommend the engagement tier that makes sense — not the most expensive one. Scope, deliverables, and expected outcomes clearly defined.

04

We start — and you feel it immediately

Most clients notice the difference within the first two weeks. Technology decisions get clearer. Security gaps get closed. AI stops being a vague ambition and becomes a working tool.
