Startup M&A: Manage International Growth with an EOR

Mergers and acquisitions are a fast track to growth for ambitious startups looking to scale quickly and capture new markets. However, when these deals cross international borders, they introduce complex challenges around workforce integration, regulatory compliance, and operational alignment that can derail even the most promising transactions.

What seems like a straightforward business expansion suddenly becomes a maze of employment laws, cultural differences, and administrative hurdles spanning multiple countries.

Whether a startup is acquiring international talent or being acquired by a global company, understanding how to navigate cross-border workforce transitions becomes mission-critical. The stakes are high—research shows that 70% to 90% of acquisitions fail, often due to issues with workforce and cultural alignment. Poor integration can result in talent loss, legal complications, and operational disruptions that undermine the strategic value of the deal.

This guide walks through the global M&A process from a workforce perspective and demonstrates how partnering with an Employer of Record (EOR) can transform these complex transitions into streamlined operations. An EOR handles the legal, compliance, and administrative complexities, allowing companies to focus on strategic integration and growth objectives.

What is the startup M&A process?

The startup M&A process follows a structured sequence of stages that can span anywhere from six months to over two years, depending on deal complexity and regulatory requirements. Each stage builds upon the previous one, requiring careful coordination among legal, financial, and operational teams.

1. Deal sourcing or strategic planning. Companies identify potential acquisition targets or position themselves for sale through market research, networking, and relationship building with investment bankers or advisors. This initial stage involves creating target lists and establishing a strategic rationale for the transaction.
2. Due diligence (financial, legal, HR, compliance). Buyers conduct comprehensive audits of the target company’s finances, operations, technology, and workforce to identify potential risks and liabilities. HR due diligence examines employee contracts, pension obligations, ongoing legal claims, and compliance with labor laws.
3. Valuation and negotiation. Both parties work to establish a fair market value using methods like discounted cash flow analysis, market comparisons, and recent deal benchmarks. Negotiations encompass the purchase price, payment structures, representations, warranties, and risk allocation between the buyer and seller.
4. Transaction closing. Legal teams execute transaction documents, including purchase agreements, bills of sale, and assignment agreements, while securing necessary third-party consents and regulatory approvals. This stage finalizes the legal transfer of ownership and assets.
5. Post-merger integration (PMI). The acquiring company integrates the target’s operations, systems, and workforce into a unified entity. This process can take 6-12 months and determines whether the merger achieves its strategic objectives.

Global M&A requires added attention to workforce compliance, local labor laws, and operational continuity across multiple jurisdictions. International transactions must navigate varying employment regulations, tax structures, and cultural differences that can significantly impact the success of integration.

Global M&A challenges startups face

When startups pursue cross-border M&A opportunities, they encounter a complex web of operational, legal, and cultural obstacles that domestic transactions rarely present. These challenges can significantly extend deal timelines and increase integration costs if not properly addressed from the outset.

• Entity management. Managing legal entities across multiple countries creates administrative complexity. It can also delay integration as companies must navigate different reporting requirements, governance structures, and jurisdictional differences that make finding operational efficiencies nearly impossible.
• Workforce compliance. Differing labor laws, employment contracts, and benefits structures across countries create significant compliance risks, as companies must understand varying regulations, tax implications, and legal requirements to avoid fines and legal disputes.
• Payroll transitions. Switching global employees or contractors to a unified payroll system carries inherent risks, including payroll errors, compliance failures, and data breaches that can disrupt operations and damage employee trust during the critical integration period.
• Cultural alignment. When integrating international teams, employers often encounter substantial barriers, including unfamiliarity with cultural norms, language differences, and varying communication styles, which can lead to reduced cooperation, productivity loss, and misunderstandings between merged organizations.
• Benefits harmonization. Aligning equity compensation plans, time-off policies, and employee benefit expectations across different countries requires careful coordination to maintain talent retention while managing cost structures and regulatory compliance.
• Immigration and employment eligibility. Transferred executives, key personnel, and remote team members may face visa requirements, work authorization challenges, and employment eligibility issues that can complicate workforce integration and limit operational flexibility post-merger.

Keeping talent onboard is a perpetual struggle for newly acquired startups. “Research indicates that post-acquisition, 33% of the workforce in the targeted company is likely to quit within 12 months,” reports M&A advisor Alejandro Cremades. “You can also expect that up to 75% will leave the new company within three years,” he adds.

How an EOR supports global M&A

An Employer of Record is a third-party service provider that becomes the legal employer for a company’s workforce in international markets. The EOR handles all employment-related responsibilities, including payroll, taxes, benefits administration, and compliance with local labor laws. This arrangement allows companies to employ international talent without establishing their own legal entities in each country.

For startups navigating global M&A transactions, partnering with an EOR offers critical infrastructure to manage complex workforce transitions smoothly and compliantly. Here’s how an EOR supports the process:

• Speed up integration. Companies can onboard or retain talent in new markets immediately without the lengthy process of setting up local entities, which typically takes 6-12 months and requires significant legal and administrative resources.
• Mitigate misclassification risk. The EOR properly classifies employees and contractors according to local regulations post-acquisition, reducing the risk of costly penalties and legal disputes that can arise from incorrect worker classification.
• Ensure compliance. EOR providers handle complex labor laws, tax regulations, and mandatory benefits requirements in each country, eliminating the need for internal teams to become experts in dozens of different legal frameworks.
• Maintain business continuity. Employees experience no disruptions in payroll processing, benefits coverage, or employment status during the transition period, which helps retain key talent and maintain productivity.
• Simplify due diligence. EOR providers maintain clear and organized records of employees and contractors. This streamlines the due diligence process and provides transparency into workforce costs and compliance status.
• Support equity transitions. EOR services can help manage global equity compensation changes during mergers or acquisitions, ensuring compliance with securities laws and tax regulations across multiple jurisdictions.

For example, Velocity Global enables startups to keep acquired teams in-market under a unified, compliant employment structure without delay. Rather than spending months establishing legal entities or risking compliance violations, companies can complete their M&A integration while the EOR handles all employment complexities behind the scenes.

Step-by-step: How to manage global talent during an M&A deal

Successfully managing global talent during an M&A transaction requires a structured approach that addresses workforce complexities at each stage.

1. Pre-deal planning

The foundation of successful global talent management begins well before any deal announcement by identifying global headcount, contract types, and labor risks early in the process.

Companies must conduct comprehensive talent assessments to understand skills, experience, and potential flight risks within the target company’s workforce. Working with legal and HR advisors helps assess people-related liabilities across different jurisdictions and enables strategic decision-making about talent retention and employment structure post-acquisition.

2. Due diligence

The due diligence phase requires a thorough review of local employment contracts, benefits packages, and statutory obligations in each country where the target company operates. This includes analysis of workforce policies, training programs, paid time-off policies, and payroll administration systems.

Utilizing an EOR to conduct local compliance audits provides expert insight into regulatory requirements and helps identify independent contractor risks, ensuring proper worker classification following local regulations.

3. Transition planning

Creating a detailed talent transition plan is critical for employees in markets where the acquiring company lacks legal entities. Companies must map out how to maintain employment relationships without lengthy entity setup processes that can take six months or more to complete.

The transition plan should determine whether to convert contractors to employees or retain current contractual relationships through an EOR structure while addressing potential “orphaned employees” during integration.

4. Post-deal execution

Immediate post-close execution focuses on maintaining employment stability for global teams while integration proceeds. An EOR enables companies to retain international talent immediately without disrupting payroll or employment status.

The execution phase involves gradually integrating teams into new systems and technology stacks while maintaining operational continuity. Companies should align culture and communication through centralized policies while respecting local practices and regulations. Establishing comprehensive onboarding programs for the merged entity helps create unity and purpose among employees from both organizations.

EOR vs. entity setup: What’s best for M&A?

When managing global talent during M&A transactions, companies must decide whether to use an EOR or establish their own legal entities in target markets. The decision depends on several critical factors that can impact deal timelines and the success of integration.

To streamline global M&A, EORs offer significant advantages in speed and risk reduction, allowing companies to retain acquired talent immediately without the 6-12 month entity setup process.

Many startups use an EOR as either an interim solution during integration or a long-term strategy for markets where they plan to maintain smaller teams, enabling them to focus on strategic priorities while ensuring workforce continuity.
