The software I build, not just advise on

Alongside advising founders and family offices, I design and ship real products of my own — from business security and finance to research and productivity tools. Here’s what’s live, in early access, and coming.

CentroKey · centrokey.com

CentroKey Vault

Live

Know who holds the keys to your business.

Type your domain and watch your technology map itself — domains, email, hosting, websites, SSL and suppliers. CentroKey Vault then becomes a living register of who controls what, where the keys live, and what’s about to expire — so the knowledge never sits in one person’s head or a forgotten spreadsheet.

  • Automatic discovery from a single domain — no installs, no logins to hand over
  • Renewal & expiry alerts with a simple traffic-light risk view
  • Key contacts and supplier register in one place
  • UK-hosted, UK GDPR — we store the map, never the keys

Your business, mapped

  • Domain
  • Email
  • Website
  • SSL & security
  • Backups
  • Hosting & suppliers

Free to start · 1 owner, up to 2 businesses

Paired with CentroKey Sentinel — continuous attack-surface monitoring and AI-assisted security validation for MSPs and growing businesses (early access).

Discover Ayah · discoverayah.com

Discover Ayah

Live

Could a human have written this?

Ask anything about the Qur’an and get a clear, plain-English answer — free. Then reveal the evidence, follow up, or challenge it. Every claim is stress-tested by an Advocate, a Sceptic and an independent Judge, with transparent, deterministic scoring. Always grounded in the text, always open to question — never asserted as settled fact.

  • Plain-English answers, free to ask
  • Reveal the facts — every relevant verse (Arabic + English), word-roots and cross-references
  • Adversarial by design — the AI argues both sides before anything scores
  • Transparent evidence scale, from Exceptional to Failed — and it’s allowed to say “we don’t know”

Live · exclusive for VIP clients

Live today, and reserved for VIP clients — an exclusive tier for those who want everything handled, quietly.

White-glove support

TechButler Privé

Your private technology concierge, on call.

An exclusive live-support platform offering AI-enhanced technical assistance and predictive maintenance for clients who demand white-glove service — issues resolved, often before you notice them.

SAR Guardian AI

Live · VIP only

Resilient by default. Ahead of the threat.

Dark-web monitoring

SAR DarkWatch

Live · VIP only

We watch the dark web, so you never have to.

AI-powered monitoring of client data exposure and digital risk across the deep and dark web — continuous, silent, essential. You’re told the moment something surfaces, and what to do about it.

Early access

Productivity

SAR Todo

Early access

Everything you need to do — nothing you don’t.

A fast, focused to-do app that installs like a native app and works anywhere, with paid tiers for people who want more power. Simple on the surface, serious underneath. In early access now, ahead of a full public launch.

Finance

VisualFin

Early access

Your finances, finally visual.

Multi-company finance and bookkeeping in one place — invoices, bills, contacts, cash runway and clear dashboards — so business owners can see where the money is without living in a spreadsheet. In early access with a first group of users.

Agencies

Atlas

Early access

The operating hub for marketing agencies.

Open any client and see the whole lay of the land — status, scope, owners, and where the work actually lives (Looker, Trello, Slack, Dropbox and more). A grounded AI assistant answers questions and drafts content from that client’s record, and you keep what’s useful with one click. In early access with agencies now.

Business

NX Business Suite 360

Early access

The AI-powered operating system for your business.

An all-in-one CRM and business suite with AI woven through — the everyday hub a growing business runs on, from contacts and pipeline to the daily work, without stitching ten tools together. In early access now.

In development

Security

NX Raqib 360

In development

One engine. Two shields — for your site, and for your AI.

A unified AI & web security platform — two products over one detection engine. NXSentry protects any website or web app, including the new AI endpoints sites now expose; NXShield inspects an organisation’s own use of AI, sitting between its environment and its LLM and tool servers. Built for government, large corporates and MSPs, with data sovereignty at its core.

In build

Legacy & continuity

Eterno DNA

In development

Your Digital DNA — so nothing is lost when you can’t be there.

A private, guided vault and playbook that captures your whole footprint — personal, family, financial, legal, business and digital. If you die, are incapacitated, or are simply unavailable, your family and trusted deputies know exactly what exists, where it is, and what to do, step by step.

In build

Content

QuillPost

In development

Describe it — get a month of content.

An AI content studio for creators and small teams. Describe your brand or topic and it generates carousels, posts, blog articles and emails tailored to each platform, then plans them on a calendar. You stay in control — it never auto-publishes.

In build

Personal AI

Digital Me

In development

Your own AI clone.

Dump in your data, files and knowledge, and Digital Me becomes a working clone of you — able to answer, draft and act the way you would. Everyone gets their own: a private brain that learns from everything you feed it.
