Interim CTO Leadership
Stabilising, resetting, and accelerating through change. I step into the CTO seat and take full accountability for technology leadership — from day one.

Why it matters
Execution Matters
I step in when technology decisions begin to affect delivery, margin, risk, or valuation.
CEOs, Chairs, ScaleUps and Operating Partners bring me in when they need a senior technology leader in the seat now — with the authority and experience to stabilise teams, reset delivery, make vendor and architecture decisions, and report credibly to the board. I take accountability for outcomes, not just advice.
What I do
Services
Fractional CTO Leadership
Strategic guidance without full-time commitment. For businesses that need a senior technology voice at the table without the cost of a permanent hire.
Cybersecurity Leadership
Board level governance, compliance readiness, and risk oversight. From ISO 27001 to NIS2, I lead security programmes through certification and incident response.
Engineering Turnaround
Resetting delivery and rebuilding momentum. When engineering teams are stuck, I diagnose root causes, rebuild confidence, and get delivery back on track.
AI Implementation
Moving AI from pilot to production. I help businesses identify where AI creates real value, build the infrastructure to support it, and ship systems that work at scale.

From the Field
Perspectives on technology leadership, M&A, AI, and the hard problems that keep boards and CEOs awake at night.
Most PE Firms Are Using AI to Speed Up Engineering. The Real Value Lies Upstream.
Private equity firms are deploying AI to accelerate code generation and testing — but the bigger opportunity is in due diligence, portfolio monitoring, and deal origination.

Operational shortcuts taken in one part of a business rarely stay contained. If basic hygiene is missing in one area, the security posture is almost certainly compromised elsewhere.
Read MoreWhy 88% of AI Pilots Fail, and How to Beat the Odds
Most AI pilots fail not because the technology doesn't work, but because organisations lack the data infrastructure, change management, and business case rigour to reach production.
Read MoreSuccession Isn't Just a People Problem, It's a Platform Risk
When a CTO leaves, boards focus on the people gap. The more dangerous gap is the knowledge embedded in undocumented decisions, tribal processes, and architecture choices that only one person understood.

Due diligence must now include a technical review of AI claims. Many targets overstate AI maturity — knowing the right questions to ask can protect deal value.

Integration teams are under pressure to deliver synergies fast. Automation looks like the answer. But without orchestration discipline, you automate chaos, not efficiency.

Michael Doody
Contract & Interim CTO. I step into CTO and technology leadership roles when execution can't wait.
Over 25 years I've led technology, product, and engineering in FTSE-100, Nasdaq-listed, PE-backed, and venture-backed businesses across Europe, the US, and Asia. I've integrated acquisitions, built platforms serving millions of users, shipped production AI systems, and led security programmes through certification and incident response.
I work with CEOs, Chairs, and operating partners who need a senior technology leader in the seat now — someone with the authority and experience to stabilise teams, reset delivery, make vendor and architecture decisions, and report credibly to the board.
Problems I Solve
- CTO succession gaps with no obvious internal candidate
- Engineering delivery that has stalled
- Post-M&A platform chaos and competing roadmaps
- AI initiatives stuck in pilot purgatory
- Security posture that won't survive due diligence
"I take accountability for outcomes, not just advice. Whether it's a focused turnaround or a twelve-month interim mandate, I work in the role — not from the sidelines."
Based in Dublin. Serving Ireland, UK, Europe & the US.
