Case Studies

Transformation outcomes, not activity.

A snapshot of recent Wellstone engagements leading data, AI and cloud transformation for global organisations.

Private Equity

Global Private Equity & Credit Investor

A leading private equity and credit investor needed to accelerate AI adoption across its investment lifecycle. Experimentation was stalling, with no governance framework to scale it safely across deal teams.

Engagement: 6 months

Our Approach

We defined the enterprise AI strategy, stood up an AI governance and data-ethics framework, and enabled AI-powered deal research and portfolio analytics on Azure, Snowflake and leading LLMs.

Telecommunications

European Telecoms Operator

A major European telecoms operator's data and AI delivery was fragmented and slow. It needed a secure, sovereign cloud foundation to move faster without compromising governance or compliance.

Engagement: 22 months

Our Approach

We delivered Enterprise-wide GenAI and Data platform transformation consolidating 20+ legacy platforms and 100+ applications onto a modern GCP-based ecosystem, strengthened data governance and sovereignty, and lifted AI delivery velocity and engineering maturity across the programme as interim delivery lead.

Telecoms & Media

UK Telecoms & Media Group

A UK telecoms and media group's consumer-marketing data ran on ageing legacy platforms — high cost, no real-time personalisation, and mounting customer churn eroding lifetime value.

Engagement: 3+ years

Our Approach

We led a live-live migration of consumer-marketing data to Google Cloud, built a data mesh and DataOps capability, and decommissioned legacy systems — enabling a 360° customer view and real-time personalisation.
