Engagement approach

How Daniel works with clients

Senior-led delivery across every engagement — from pre-deal technical due diligence through to post-integration optimisation and ongoing fractional leadership.

Understand the deal

Every engagement starts with understanding the commercial context — the deal structure, value creation thesis, and where technology risk or opportunity concentrates.

Assess and risk-score

Structured technical due diligence producing a risk register, synergy model input, and integration complexity estimate — built to inform price negotiation and post-close planning.

Plan and execute

Repeatable Day-1 and Day-100 playbooks refined across 10+ acquisitions — covering identity, security, collaboration, network, and data — delivered within a defined timeline.

Validate and close

Formal synergy realisation reporting, integration programme closure, and handover to steady-state operations — with a measurable record of outcomes delivered against the original deal model.
