Stack Sphere is the consulting practice of Andy Sawyer, helping organisations strengthen data strategy, modernise platforms, improve governance, and deliver analytics, AI and automation outcomes that are commercially useful - not just technically interesting.
Designed for organisations that need senior support across advisory, transformation, delivery leadership, capability uplift, or hands-on data modernisation.
Clarify priorities, shape practical roadmaps, define decision rights, and align data capability to business outcomes, risk obligations and delivery capacity.
Improve architecture, pipelines, modelling practices, data quality visibility, stewardship and platform delivery so the foundation is reliable and scalable.
Senior data leadership available to your organisation without the cost of a permanent hire - ideal when you need strategic direction, a step-up in delivery pace, or capability that isn't yet in the team.
Andy’s background spans listed enterprises, private equity-backed multinationals and scale-ups, with leadership across data engineering, business intelligence, automation, enterprise systems and consulting.
Stack Sphere is intentionally positioned as a founder-led practice: senior enough to talk strategy with executives, practical enough to help teams make real delivery progress.
Andy Sawyer is a strategic data leader with a background in finance, enterprise systems, business intelligence, data engineering and consulting. As a Certified Practising Accountant, he brings rare commercial depth to data leadership - able to frame data investment in CFO terms, align delivery with business objectives, and engage credibly at board and executive level.
A business and data background that bridges the commercial and the technical.
Stack Sphere is available for consulting, advisory and interim leadership engagements. Reach out to discuss your needs - no obligation, no sales process.
