Phenomlab is now Gratmore.
The name has changed. The experience, accountability and principles behind the business have not.
I established Phenomlab as a vehicle for providing senior technology and cyber security leadership outside the traditional permanent executive model.
Over time, the work has evolved.
The conversations I now have with boards, CEOs and leadership teams increasingly extend beyond a fractional CIO or CISO requirement.
They are about technology strategy, cyber risk, operational resilience, governance, assurance, difficult decisions and developing executive capability.
The business needed to reflect that.
Gratmore is built around four ways I can help:
- Lead. Fractional and interim executive leadership where accountability is required.
- Advise. Independent executive judgement and challenge for boards, CEOs and technology or security leaders.
- Assess. Defined reviews, due diligence and assurance where an organisation needs an independent answer.
- Develop. Executive mentoring and transition support for CIOs, CISOs and leadership teams.
It is still me behind it.
- More than 30 years in technology.
- More than 20 years in executive leadership.
- Eight years carrying concurrent CIO and CISO accountability.
- Experience spanning technology, cyber security, governance, transformation, operational resilience and regulated environments.
But Gratmore represents that experience much more accurately than Phenomlab did.
A new name. A considerably clearer proposition.
Lead. Advise. Assess. Develop.
Gratmore.
Phenomlab is changing.
- Not the work.
- Not the experience.
- Not the standards.
The identity.
I’ve been working on something quietly for a while now, and it’s nearly ready.
More soon.
Watch this space.
Thought I'd share a video intro of myself - hope this is of some use to understand who I am and the services I provide.
CIO & CISO | Executive Technology, Cyber & Governance Leadership | Permanent, Interim & Fractional
After more than 30 years leading technology, cyber security and governance within complex, regulated organisations, I'm now focused on my next executive appointment.
I'm available for:
- Permanent CIO or CISO appointments
- Interim executive leadership
- Fractional CIO and CISO engagements
- Executive advisory and board support
My experience includes eight years serving concurrently as CIO and CISO for a global alternative investment manager, providing integrated executive accountability across technology, cyber security and operational resilience.
I'm particularly interested in opportunities where executive ownership, governance and technology strategy are critical to organisational success.
If you're looking for senior technology or cyber leadership, or know an organisation that is, I'd be pleased to have a conversation.
