The Founder's Edge

We have actually run the businesses we advise.

Grant & Graham was founded in 2009 by Andrew Collins, who scaled Service Industries Ltd from $15 million to $220 million before its acquisition by NCR.

That operating DNA runs through everything we do. Our senior consultants are former CEOs, CROs, CFOs, and transformation directors. People who have held the roles, carried the number, and delivered the outcome — not career advisers.

When we place someone into your business, they do not need a runway to be useful. They have been there and solved that.

The Senior Team

Senior operators. Globally placed.

Each Grant & Graham consultant has held the role at scale before. Operating background. Sector depth. Country fluency. The full network — names, roles, regions — sits on the team page.

Why Grant & Graham

Six reasons clients keep calling back.

01

Senior consultants only

Every engagement is led by a practitioner who has done the job at scale. No juniors learning on your time.

02

Speed

Interim placements in days, not months. GaaS engagements live within weeks. Consultancy scoped and started inside a fortnight.

03

Global reach, local expertise

100+ offices across six continents and 36 countries, with senior consultants on the ground in every market we serve.

04

Commercial focus

We measure our work in outcomes — revenue unlocked, transformation delivered, deals closed. Not in hours billed.

05

Flexible engagement models

Fractional, interim, project-based, retained. We design the engagement around the business problem, not a standard product.

06

Board-level accountability

Our consultants operate at C-suite level and are accountable for outcomes, not just deliverables. That is the Grant & Graham standard.

Sectors We Serve

More than 20 sectors. Specialists, not generalists.

We match the right consultant to your sector — not a generalist who is reading up on your industry on the flight over.

Restructuring Without the Wreckage: A Practical Guide for Leadership Teams

The word restructuring carries weight. For leadership teams, it means strategic realignment. For the rest of the organisation, it often means uncertainty. Here is how senior practitioners handle both sides — without breaking what is working.
