Middle Market Integration Firm

When a deal closes, the real work begins. Stonehill is a leading middle market integration firm helping private equity sponsors and corporate acquirers turn signed transactions into realized value. We specialize in post-merger integration — the critical 90 to 180 days where culture, operations, technology, and talent either align or unravel. Our clients don't hire us to manage checklists. They hire us because they can't afford to get integration wrong.

Stonehill brings a rare combination of M&A fluency and operational depth to every engagement. Founded on the belief that middle market companies deserve the same caliber of integration expertise as the Fortune 500, we work alongside leadership teams to accelerate synergy capture, reduce integration risk, and build the organizational foundation that makes growth sustainable. From day-one readiness through full operational alignment, we are the integration partner that stays until the work is done.

Service Offerings

• Post-Merger Integration (PMI) Management End-to-end integration planning and execution across all functional workstreams — finance, HR, technology, operations, and commercial. We establish and run the Integration Management Office (IMO), drive accountability across teams, and ensure that day-one readiness, synergy realization, and cultural alignment happen on schedule and on plan.

• 100-Day Integration Planning A structured, sprint-based engagement that defines your integration roadmap before the deal closes. We build the governance model, prioritize workstreams by value and risk, establish KPIs, and equip your leadership team with a clear, executable plan so the first 100 days drive momentum rather than confusion.

• Synergy Identification & Realization We go beyond the deal model. Stonehill helps acquirers systematically identify, validate, and capture cost and revenue synergies — building the tracking infrastructure and cross-functional alignment needed to turn projected synergies into line-item results that show up in EBITDA.

• Organizational Design & Change Management Mergers create organizational ambiguity. We help leadership teams design the right post-close structure, define roles and reporting relationships, and lead the change management process that brings employees along. The result is a workforce that understands the vision, trusts the leadership, and stays.

• Technology & Systems Integration One of the most complex and highest-risk elements of any integration is the convergence of systems, data, and platforms. Stonehill assesses the technology landscape across both entities, builds a rationalization roadmap, and manages the integration process to minimize disruption while positioning the combined company for scalable growth.

Stonehill has partnered with leading private equity firms, regional banks, national restaurant brands, and global consumer companies to navigate some of the most complex integrations in the middle market.

If you are preparing for a transaction, in the middle of one, or trying to recover value from an integration that has stalled, Stonehill is ready to help. As a purpose-built middle market integration firm, we exist to do one thing exceptionally well — make your deal work. Let's talk about what that looks like for your organization.
