"Alderton's diligence work was the most rigorous we have seen from any advisory firm at this deal size."
Managing Partner, European Mid-Market PE

A focused
practice built
for complexity.

We do not offer everything. We offer depth — a tightly scoped set of capabilities where we have built proprietary frameworks and a demonstrable track record of impact.

01
Commercial & Strategic Due Diligence

Rigorous market and competitive analysis for private equity, infrastructure, and corporate acquirers. We stress-test business plans and surface value creation opportunities early.

02
Market Entry & Growth Strategy

From addressable market sizing to go-to-market architecture. We help clients enter new geographies and segments with evidence-backed confidence.

03
Operational Transformation

Post-acquisition value creation, operating model redesign, and cost structure optimisation — from strategic design through to implementation support.

04
Portfolio Performance

Ongoing advisory to PE portfolio companies across the hold period. Board-level support, KPI framework design, and management team effectiveness.

05
Competitive Intelligence

Sustained insight programmes tracking competitor moves, pricing dynamics, and customer sentiment — structured for decision-ready delivery.

06
Vendor & Partnership Advisory

Structuring and evaluating strategic vendor relationships, outsourcing decisions, and partnership frameworks for scalable growth.

Built on
independence
and conviction.

Founded in 2009, Alderton Advisory Group is an independent strategy consultancy with offices in London and Zurich. We are deliberately partnership-sized — structured so that senior practitioners lead every engagement.

We are not a generalist firm that staffs engagements with graduates. Every client relationship is owned by a Partner with direct sector expertise, and our analyst pool is drawn from top-tier universities and former investment banks.

Independence

We carry no conflicts from audit, tax, or technology implementation. Our advice is solely in your interest.

Partnership model

Every engagement is led by a Partner. You will not be handed off. Senior attention is not a premium — it is the standard.

Proprietary research

We maintain live databases across our core sectors, enabling faster and more grounded insight than a cold-start approach.

Where we
concentrate
expertise.

We work across a defined set of sectors where we have built proprietary data, networks, and frameworks over 15 years.
