About Us
Acquisition Integration Specialists (AIS) is a boutique consulting firm focused exclusively on post merger integration for lower and middle market acquirers. Operator-led and purpose-built for PMI, we help private equity and corporate acquirers integrate faster, capture synergies with precision, and realize full transaction value.
We lead and execute all aspects of M&A integration—from pre-close planning through Day 1 and 100-day execution to full value capture. Working shoulder-to- shoulder with management teams and sponsors, we align people, processes, and systems to ensure a seamless transition and sustained performance.
Our senior integration leaders are experienced operators who have owned P&Ls and led integrations firsthand—not career consultants. We bring a hands-on, execution-driven approach grounded in real operating experience and supported by Fortune 500 discipline.
Our deep bench and flexible resourcing model allows us to deploy the right expertise at the right time—whether a single seasoned PMI leader or a full cross- functional integration team across Finance, HR, Operations, Sales, and IT. We scale with your needs, maintaining speed, focus, and cost discipline.
At the core of our approach is Unify™, our proprietary 5-step post-merger integration process. It brings structure, visibility, and accountability from the outset—reducing execution risk, minimizing disruption, and accelerating speed-to-value.
As every company and acquisition is unique, we do not apply a one-size-fits-all approach. We tailor our integration process to the unique operational, technical and cultural issues of the merging entities.

Why Select Us?
We are dedicated to serving Private Equity-backed acquirers and going above and beyond to ensure your success. What truly distinguishes us from other firms is our exclusive focus on post-merger integration and operating mindset. Our team of acquisition integration specialists comprises experienced senior-level operating executives from top companies, who have firsthand expertise in facilitating M&A integrations. We bring to the table a proven 5-step process called Unify™ that streamlines bringing companies together. Our unique approach enables us to be fast, cost-effective, and guarantee the realization of synergies.
Integration Specialists
PMI is all we do. Unlike general management consulting and M&A advisory firms, AIS is purpose-built for integration execution. Our senior-level integration leaders bring practical experience, execution discipline, and hands-on leadership—not teams of junior analysts.
Operator Mentality
We have been in your shoes and know how to execute. Our merger integration consultants are former senior-level executives with F500 and PE-backed operating roles and proven experience facilitating complex M&A Integrations on the corporate and consulting side.
Proven Process
Our 5-step post-merger integration process helps simplify unifying companies. We utilize post-merger integration checklists, playbooks, and easy-to-use project management software to enhance visibility, collaboration and accountability.
Versatile/Agile
Our strong bench of Integration Specialists empowers us to assemble the ideal team of generalists and SME based on your industry, business, and situation. This enables us to adjust staff as the integration moves through stages.
Cost-effective
We configure our post-merger integration teams based on the size, scope, complexity and stage of each integration. Projects are staffed with specialists as needed without adding extraneous overhead. This enables us to manage resources and fees fairly.
Synergy Guarantee
We work to achieve our client's planned revenue and cost synergies. In many cases, we are comfortable linking our compensation to the actual realization of synergies.
Founder’s Message
Over the past year, we have had the privilege to engage with our Private Equity (PE) clients and industry colleagues, gain insights into the state of the M&A market, and identify what will be crucial for clients in the coming years.
After a challenging past 18 months, PE expects transaction volume to bounce-back in 2024, supported by an increase in deal pipeline and nearly $4T in dry powder.
Three key points caught our attention:
-
PE firms are increasingly looking to outsource post-merger integration as their portfolio companies often lack the expertise to effectively integrate and operationalize acquisitions, particularly those involving strategic transformations.
-
PE firms that outsource integration are shifting focus away from general consulting firms towards specialists in acquisition integration who can also bring senior-level general management experience on the corporate-side and an "operator mentality."
-
PE firms want outsourcing partners who can oversee and facilitate all aspects of post-merger integration, in collaboration with the merging companies, so that leaders can concentrate on running their business without diverting too much time on integration.
Empowered with this knowledge, we have invested considerable time and resources to strengthen our capabilities to serve the needs of Private Equity and ensure successful acquisition outcomes.
Whether you are visiting our website for the first time or have collaborated with us in the past, we thank you for your interest and continued support.
With Gratitude,

Mid-2025 Post-Merger Integration Briefing
M&A Market Update – 1H 2025
• Subdued Activity: Despite early-year optimism, PE deal volume remained muted due to market uncertainty in tariff-sensitive sectors, financing constraints, and political headwinds.
• Deal Profile: Three-quarters of middle-market transactions were add-ons, with deal flow lead by Business Services and Information Technology – particularly software and tech-enabled services.
• Challenges: Transactions are taking longer (due diligence + financing) and many fail to close. While our own PMI pipeline grew 3x, many opportunities stalled due to valuation gaps and lender constraints.
Outlook – 2H 2025
• Positive Catalysts: Greater clarity on tariffs, improving financing conditions, and pressure to reduce PE exit backlogs (highest in 20 years) may support a stronger second half.
• Market Dynamics: Add-ons will dominate in the lower-to-middle market, driven by corporate buyers, PE acquisitions, PE sponsor-to-sponsor deals, and carve-outs.
• Value Creation Imperative: In this environment, leading PE firms recognize the critical importance of value creation to accelerate growth, increase productivity, and maximize sustainable returns.
• PMI Support: While large PE firms have expanded internal operating groups, most PE firms will rely on external partners for PMI – especially when portfolio companies lack M&A integration expertise.
Post-Merger Integration (PMI) Considerations
Continued demand for external PMI support is anticipated due to:
• Heightened focus on post-close performance in the first 12-18 months to meet IRR/MOIC targets.
• Active acquirers seeking scalable, repeatable integration playbooks tailored to specific deals.
• Shift toward specialist integration firms with experienced hands-on operators who can oversee and facilitate all aspects of post-merger integration in collaboration with the merging companies/sponsors.
• Strong desire to rapidly mobilize the integration effort and start creating value. Aim for least disruption so management teams can stay focused on running the business rather than distracted by PMI details.
Key integration priorities include:
• Organization design & people integration
• Leadership & employee retention strategies
• Functional harmonization – HR, Finance, Sales/GTM, Ops, IT
• IT Systems integration – ERP, CRM, Custom Workflow Applications
• SKU & customer consolidation
• Reporting & BI integration
• Working capital (cash conversion) optimization
• Procurement & vendor management
• Synergy planning and realization tracking
Our Commitment
We continue to strengthen our capabilities to help PE sponsors achieve successful acquisition outcomes. This includes efforts to embed AI-enabled solutions into our PMI process to accelerate planning, ensure knowledge capture, track and monitor progress, identify and realize synergies, and surface risks in real time.
Thank you for your continued trust and collaboration.

Prepare for Integration Success
If you are evaluating an acquisition or preparing for a future integration, we can help. We offer a complimentary Post-Merger Integration Readiness Assessment, followed by an actionable PMI proposal tailored to your deal, timeline, and value creation objectives.
Let’s start a conversation.
When to Bring in AIS
Consider engaging us when execution risk is high and speed-to-value critical:
Internal PMI experience is limited or unproven at scale.
Management does not have the bandwidth to lead integration effectively.
Synergies are material but not yet translated into executable capture plans.
Missteps would materially impact EBITDA expansion or the deal thesis.
Execution risk is elevated (cross-border, merger of equals, dependencies).
