Patrick Sullivan

I embed as a part-time executive — days a week, not a one-off report — and own outcomes alongside your founding and leadership team. The work spans three connected mandates, and most engagements draw on more than one:

As Fractional CTO, I set technology strategy, architecture and the engineering operating cadence: build-vs-buy calls, platform and scalability decisions, team structure and hiring, vendor selection, and the roadmap that turns a product vision into a system that ships. I run technical and AI due diligence for boards and investors — validating architecture, IP defensibility and risk before capital is deployed.

As Fractional CAIO, I help organisations move past "AI curiosity" to AI that earns its keep: where AI genuinely creates value versus where it's theatre, agentic and automation design, model selection and inference economics, and the AI governance to deploy responsibly — AI control frameworks, ISO/IEC 42001, the NIST AI Risk Management Framework and the EU AI Act. I build, not just advise: production agentic systems wired into real workflows.

As Fractional CISO, I establish practical, business-aligned security governance: cyber risk and maturity assessments, security strategy and roadmaps, board and risk-committee reporting, incident-response readiness, third-party and supply-chain risk, and uplift programmes against NIST CSF 2.0, ASD Essential Eight, APRA CPS 234/230 and ISO 27001. The aim is measurable risk reduction and informed investment — not a shelf full of artefacts.

The thread through all three: I make technology, AI and cyber understandable, measurable and actionable at the executive level — and then I deliver. I've advised dozens of CISO offices, regulated-industry CTOs and government leaders, and led an APRA-scrutinised re-platforming inside a major bank. I work plainly, without hype, and tell you when something isn't worth doing.

Fractional CTO

-Technology strategy, architecture and platform decisions -Engineering team design, hiring and operating cadence -Technical & AI due diligence for boards and investors -Roadmaps from product vision to shipped system

Fractional CAIO -Where AI pays off (and where it doesn't) -Agentic AI design, automation and inference economics -AI governance: ISO/IEC 42001, NIST AI RMF, EU AI Act -Building production AI, not slideware

Fractional CISO

-Cyber risk and security-maturity assessments -Security strategy, roadmaps and board reporting -Governance frameworks: NIST CSF 2.0, Essential Eight, APRA CPS 234/230, ISO 27001 -Incident-response readiness, third-party and supply-chain risk

Sectors: All, retail, service providers, manufacturing, technology & SaaS, fintech & payments, healthtech & medtech, financial services and APRA-regulated organisations — and any high-scrutiny environment where the stakes are real.

How I work: part-time, embedded, outcomes-owned.
