Leading Post Merger Integration Firm Texas - Dallas, Austin, Houston

The deal is the easy part. Capturing the value you modeled in the deal is where most mergers break down — and where Stonehill goes to work.

We are a senior-led post-merger integration firm serving middle-market and PE-backed companies across Texas. From our Dallas office, we partner with leadership teams in Dallas-Fort Worth, Austin, and Houston to turn signed agreements into operating businesses that hit their synergy targets, retain their best people, and protect customers through the transition.

If your thesis depends on integration going right, you want practitioners who have done it before — not a staffing pyramid learning on your deal.

Why Most Texas Mergers Underdeliver

Texas leads the country in middle-market deal activity. No state income tax, a deep PE bench, and concentration in energy, industrials, financial services, and high-growth tech keep the deal flow steady. But volume isn't the problem — value capture is.

The same pattern repeats across the market:

• Day One arrives before anyone is ready. Functional leads are still running the legacy business while the integration plan lives in a spreadsheet no one owns.

• Synergy targets exist in the model, not in the org. Nobody has translated the deal math into accountable workstreams with dates and owners.

• The best people leave first. Without a clear narrative and a stake in the new organization, top performers take the call from the recruiter.

• The IMO is improvised. Integration gets bolted onto someone's day job instead of being run as the discipline it is.

Stonehill exists to close that gap. We are the firm that makes middle-market mergers work.

What We Do

• Stand Up Your Integration Management Office (IMO) - We build and run the operating system of your integration — governance, workstream charters, milestone tracking, synergy capture, and executive reporting. You get an IMO that holds the organization accountable from signing through value realization, not a binder that gathers dust after Day One.

• Day One & 100-Day Planning - We sequence the moves that have to land first — the ones that protect revenue, customers, and employees — and build the 100-day plan that turns momentum into results. Clear owners, clear dates, clear definition of done.

• Carve-Out & TSA Advisory - Buying a division, or separating one to sell? We manage the disentanglement, define and exit Transition Service Agreements, and stand up the standalone operating model so you aren't trapped paying the seller to run your company.

• Organizational Design - We design the combined organization around where the value actually is — reporting lines, spans and layers, role clarity, and the leadership structure the new business needs. Decisions made with data, not politics.

• Change Management - Synergies are delivered by people, and people need a reason to stay and a path to follow. We build the communications, leadership alignment, and adoption plans that keep your workforce engaged through the most uncertain stretch of the deal.

• AI, Automation & Analytics - Our Center of Excellence brings real-time integration dashboards, automated synergy tracking, and analytics into the IMO — so leadership sees the truth of the integration as it happens, not three weeks later in a status deck.

Post-Merger Integration in Dallas-Fort Worth

Dallas is home to our Texas team and one of the densest corporate and PE markets in the country. We work alongside Metroplex leadership teams across business services, financial services, distribution, and industrials — companies acquiring to scale, rolling up fragmented markets, or integrating a transformative platform deal. With practitioners on the ground in DFW, we embed directly with your team rather than parachuting in for status meetings.

Post-Merger Integration in Austin

Austin's growth-stage and technology companies face a specific integration challenge: combining businesses fast enough to keep their edge without breaking the culture that made them worth acquiring. We help Austin founders, sponsors, and management teams integrate with speed and discipline — protecting product velocity and talent while building the structure a larger company needs.

Post-Merger Integration in Houston

Houston's energy, industrials, chemicals, and healthcare sectors run on complex, asset-heavy, often regulated operations — exactly the environment where sloppy integration destroys value. We bring operational rigor to Houston mergers and carve-outs, managing the workstreams, TSAs, and organizational changes that make a complicated combination actually function on Day One and beyond.

Why Stonehill

• Senior practitioners do the work. The people in your war room are the people who diagnosed your deal — not a layer of junior consultants. You get experience that has integrated mergers before, in the room, accountable.

• An embedded IMO, not a staffing pyramid. We integrate with your team and transfer capability as we go, so the discipline outlives the engagement. Big firms leave when the invoice stops; we leave you able to run it yourselves.

• Design Thinking methodology. We solve integration problems with the people closest to them, building solutions your organization will actually adopt instead of resist.

• Built for the middle market. This is who we serve — PE-backed and founder-led companies where the integration is too important to improvise and too lean to overstaff. We are sized for your deal.
