Integration Management Office (IMO)
Successful integration starts long before the deal completes.

The advantage that compounds over time.
Rostone IMO brings the Grow stage into the integration story — and that changes what is possible at every stage that follows.
Due diligence built in
Operational excellence in Grow means the business holds up under scrutiny — no last-minute gaps.
Capital that delivers ROI
Investment raised in the Raise stage lands in a business built to use it productively.
Integration into a working model
Integrate into a defined, aligned operating model, not into another set of unresolved questions.
25 years programme management
Senior practitioners, embedded in the business. Experience that shows up in the room, not just on the proposal.
Built for the lower mid-market
Not a Big 4 firm repackaged for smaller deals. Proportionate, practical, and cost-effective for £1M–£50M businesses.
Valuation as your scoreboard
Every operational decision viewed through the lens of enterprise value — because that is the ultimate measure of whether the deal worked.
