Technology leadership. Without the permanent hire.
Tremalis provides experienced CTO-level leadership to organisations navigating growth, transformation and complex technology decisions — bringing clarity, accountability and momentum when it matters most.
When technology has become too important to leave without senior ownership.
Not every organisation needs a permanent CTO. But there are points where experienced executive technology leadership becomes essential.
You need a CTO — but not yet full-time
Technology decisions are becoming more strategic, but a permanent executive appointment is premature, expensive or too slow.
Transformation is not delivering
Delivery has lost momentum, accountability is blurred, suppliers are driving the agenda or the board no longer has a clear view of progress and risk.
The board needs an independent technology voice
You are making major decisions around platforms, data, AI, operating model, suppliers or investment and want experienced challenge before committing.
Three ways to bring senior technology leadership into the business.
Fractional CTO
Ongoing executive technology leadership as part of your senior team. Strategy, priorities, organisation, suppliers, delivery, risk and board communication — with clear ownership rather than occasional advice.
Transformation Leadership
Independent executive leadership for complex technology and digital transformation. Re-establish direction, strengthen governance, create accountability and turn plans into measurable delivery.
Board & CEO Technology Support
Independent support for high-impact decisions — technology investment, AI strategy, supplier selection, organisation design, platform direction and transformation assurance.
Senior enough for the board. Close enough to the work to know what will actually deliver.
Tremalis is founded by Tony Melia, a senior technology executive with experience leading large-scale transformation and multi-disciplinary technology organisations across engineering, data, cloud, infrastructure, testing, support and delivery.
The value is not another strategy deck. It is experienced ownership: setting direction, making the difficult calls, creating clarity across teams and suppliers, and giving the board confidence that technology is moving the business forward.
Embedded where needed. Independent where it matters.
Tremalis is designed to be practical. The role can flex from a regular fractional CTO commitment to focused leadership around a transformation, investment decision or period of change.
Clarity first
Start with the business outcome, current constraints and the decisions that genuinely matter. Technology follows the commercial agenda — not the other way around.
Ownership, not observation
Where Tremalis is engaged to lead, there is clear accountability for direction, priorities, governance and executive communication.
Independent challenge
No product to sell, no supplier agenda and no incentive to make the technology landscape more complicated than it needs to be.
