Operators first. Advisers second.
A global interim management and strategy consultancy, founded in 2009. Our senior practitioners have run the businesses they advise — carrying the number, leading the team, delivering the outcome. That is the standard we bring to every engagement.
The year it all started.
Grant & Graham was founded on a simple belief: that the right senior talent, placed at the right moment, changes the trajectory of a business.
Since 2009 we have been dedicated to providing expert management solutions tailored to the unique needs of our clients. Our founding focus has remained the same to this day — to quickly place seasoned managers with proven track records into the roles our clients need most, whether that is navigating a short-term challenge or leading a long-term transformation.
What began as a small interim management practice has grown into a global consultancy with 100+ offices across 38 countries and six continents, a senior network of practitioners, and delivery experience across more than 20 sectors.
Through every chapter — start-up to scale-up, one country to six continents — the commitment has not changed. Senior practitioners. Real accountability. Outcomes measured in the commercial result, not the hours billed.
Three words that shape how we work.
Strategize. Organize. Globalize. Not a tagline — a sequence. It is how we think about every client engagement, from a 90-day interim placement to a multi-year transformation mandate.
Strategize
We start with the commercial problem, not a framework. Our consultants have sat in the seat before — so the strategy we build is grounded in what actually works, not what reads well in a deck.
Organize
We put the team, the structure, and the operating model in place to deliver. Interim leaders, Growth as a Service pods, change management specialists — matched precisely to the engagement.
Globalize
With 100+ offices across 38 countries and on-the-ground expertise in 100+ jurisdictions, we help clients enter new markets, expand international operations, and scale with confidence.
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 Corporation.
That operating DNA runs through everything we do. Our senior consultants are former CEOs, CROs, CFOs, CTOs, 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.
