At Six3Nine, we specialise in comprehensive procurement transformations and converting M&A model assumptions into realised EBITDA impact. We provide end-to-end strategic support across the entire transaction lifecycle—from pre-deal screening and due diligence to navigating complex mergers, carve-outs, and IPO preparations.
We protect value by optimising procurement operating models, global supplier ecosystems, and high-stakes commercial contracts. Operating as an extension of procurement and M&A value creation teams, we replace traditional, heavy consulting structures with targeted, high-impact advisory support—delivered exactly when and where it is required.
We deploy an agile, precision-engineered alternative to traditional consulting, anchored by elite corporate heritage:
Enterprise Pedigree: Our leaders are a cohort of senior practitioners who have spent decades steering multi-billion-pound procurement organisations and high-stakes transformation programmes within global giants, including Atos IT Services, Eviden (Bull Supercomputers & Cybersecurity), Siemens AG, and McKinsey. Highly experienced in guiding complex procurement functions through intense M&A environments, we specialise in turning operational procurement strategy directly into tangible EBITDA impact.
Bespoke Senior Teams: We do not deploy junior analysts. We assemble dedicated cohorts of experts, ensuring highly specialised capability is on the ground when needed.
Direct Principal Access: Clients work directly with experienced M&A and procurement executives who bring the seasoned judgement, boardroom credibility, and hands-on execution required to deliver tangible results in complex environments.
Pre-Deal Screening & Due Diligence: Rapidly assessing procurement maturity, cost-saving run rates, and supply-chain risks prior to binding offers.
Mergers & Integrations: Harmonising disparate procurement functions and consolidating supplier bases to capture immediate scale synergies.
Carve-Outs & Divestitures: Disentangling complex global contracts, shared systems, and intricate supplier dependencies; designing standalone target operating models (TOM) to rapidly eliminate Transition Service Agreement (TSA) reliance.
IPO Preparation: Upgrading governance, risk reporting, and contract portfolios to maximise margin health ahead of public market scrutiny.
Procurement Transformation: We transform procurement through organisational redesign, technology and AI enablement, category strategy development, and supplier negotiations, generating sustainable cost efficiencies, stronger governance, lasting commercial outcomes, and measurable EBITDA improvement.
Minimised Deal Risk: Safeguarding business continuity and operational stability during critical transition windows.
Accelerated Synergy Realisation: Converting paper-based transaction assumptions into hard, audit-ready EBITDA impact ahead of schedule.
AI-Driven Procurement Efficiency: Architecting lean, high-velocity procurement functions where human expertise is augmented by AI automation to permanently remove manual friction.
