Post Merger Integration Consulting Firm

Stonehill is a post-merger integration consulting firm helping leaders turn deal value into real operational results. After the transaction closes, execution becomes everything—aligning teams, integrating processes, and delivering synergies without disrupting customers, employees, or day-to-day performance. We bring structure, clarity, and momentum to the work that determines whether a merger succeeds.

Post-merger integration is complex because it’s both strategic and highly practical. Stonehill supports executives with a clear integration roadmap, strong governance, and hands-on leadership to coordinate workstreams across functions. We help you define integration priorities, set decision rights, manage dependencies, and keep leadership aligned through fast, transparent reporting.

Our team works alongside yours to reduce risk, accelerate timelines, and build a unified operating model. Whether you’re integrating systems, consolidating operations, or aligning culture and leadership, we focus on measurable outcomes—cost savings, improved performance, and a smooth transition for employees and customers.

Stonehill supports PMI engagements with:

  • Integration strategy and synergy planning

  • Integration Management Office (IMO) design and leadership

  • Workstream planning and execution (Finance, Ops, IT, HR, Sales)

  • Day 1 readiness and stabilization planning

  • Systems and process integration support

  • Organizational design and change management

  • Executive dashboards, risk management, and decision cadence

If you need a post-merger integration consulting firm that can lead the details while keeping the big picture in focus, Stonehill is ready to help. We combine disciplined program management with strategic insight to ensure your integration stays on track, your teams stay aligned, and the value of the deal is fully realized.

Let’s talk about your acquisition, timeline, and integration goals—and build a plan that delivers results.
