David Kernan

I help scale-ups turn messy systems, fragmented data, and unclear reporting into reliable commercial, operational, and AI-ready foundations.

My work sits at the intersection of data strategy, architecture, analytics, automation, and hands-on implementation. I typically support companies that have outgrown their current data setup, are struggling with disconnected SaaS tools, inconsistent metrics, poor reporting, or unclear ownership of data and AI initiatives.

Through definedata.io, I provide fractional senior data and technology leadership for companies that need experienced direction without immediately building a large permanent team. This can include data architecture reviews, modern data stack design, CRM and go-to-market data improvements, dashboard and KPI frameworks, automation, AI enablement, and practical delivery support.

I am particularly useful where a company needs someone who can bridge the gap between leadership, commercial teams, technical teams, and external vendors. I help identify what is broken, prioritise what matters commercially, and either lead or support the implementation of a cleaner, more scalable data and AI operating model.

Typical areas I help with include:

* Data strategy and architecture for scaling businesses
* Fractional CDO / Head of Data support
* CRM, revenue operations, and go-to-market data foundations
* KPI, reporting, and executive dashboard design
* AI readiness, automation, and data model design
* Data team structure, hiring plans, and delivery governance
* Practical clean-up of fragmented data systems and workflows
