What Acquirers Really Look At When They Buy Your Tech Company
TL;DR: Technology due diligence determines whether your tech company acquisition closes at your target price. Acquirers examine architecture scalability, code quality, security posture, compliance gaps, customer concentration, and cloud costs. Technology integration issues cause 30 percent of failed mergers. Companies that prepare early with sell-side due diligence gain negotiating leverage and better valuations.
Core Questions Acquirers Ask:
Can this technology scale without manual intervention at 10x or 100x growth?
What security vulnerabilities and compliance gaps exist that create balance sheet risk?
How concentrated is revenue across customers, and what happens if top accounts churn?
What technical debt exists, and how much will it cost to fix post-acquisition?
Are AI capabilities production-ready with proprietary models and clear data rights?
I've watched deals fall apart in the final stretch. Not because the product was weak or the revenue was wrong. Because the acquirer found something in the technology stack that nobody expected.
The due diligence phase reveals what you actually built versus what you said you built. And the gap between those two things determines whether you close at the number you want.
Here's what I've learned from sitting on both sides of tech acquisitions.
Why Technology Due Diligence Matters
Technology integration issues account for roughly 30 percent of failed mergers. That's not a small number when you consider that global M&A deal value hit $3.4 trillion in 2024.
Between 40 and 60 percent of expected synergies link directly to IT integration success. Yet only one in four CEOs report conducting technology due diligence for most of their deals. Even though 74 percent call technology a growth enabler.
That gap creates opportunity. Companies that approach tech due diligence with rigor gain leverage. Companies that skip it pay later.
KPMG found that 62 percent of deals don't hit their financial targets mainly because of poor due diligence. The consequences go beyond missed synergies. They show up as unexpected cloud bills, security incidents, compliance fines, and integration delays that drain value for years.
What This Means: Technology due diligence creates competitive advantage because most acquirers skip it, yet it directly determines whether deals achieve expected synergies and ROI.
What Do Acquirers Examine During Tech Due Diligence?
Acquirers want to know three things. Can this technology scale? What will break? How much will it cost to fix?
They start with your architecture. Can your infrastructure support 10x user growth without manual intervention? What happens at 100x? How much of your scaling process requires people versus automation?
Cloud costs often bring surprises. Many companies run into unexpected bills when their systems can't handle more demand. Acquirers need to know about hosting costs, scalability limits, and vendor lock-in. These cost projections directly affect post-acquisition EBITDA and ROI calculations.
Then they look at your code. Technical debt translates into increased maintenance costs, slower development, and diminished system reliability. A thorough review evaluates the maturity, scalability, and uniqueness of your technology stack. It uncovers hidden costs like outdated infrastructure or unplanned upgrade expenses.
Open source and third-party software comprise approximately 75 percent of the typical software codebase. With AI-generated code from tools like GitHub Copilot, the risk of unintentionally incorporating snippets with incompatible licenses or hidden vulnerabilities increases. This makes snippet-level scrutiny essential in M&A transactions involving software assets.
Three Core Questions
Can this technology scale? Infrastructure must support 10x to 100x user growth without manual intervention.
What will break? Technical debt increases maintenance costs and slows development velocity.
How much will it cost to fix? Cloud costs, vendor lock-in, and outdated infrastructure create hidden expenses that affect post-acquisition EBITDA.
The Reality: Acquirers price architectural weaknesses, technical debt, and scaling limitations into their offer or require escrow holdbacks until you fix them.
How Do Security and Compliance Affect Deal Value?
Security vulnerabilities create massive exposure. Intangible assets like proprietary software and intellectual property comprise 80 percent of M&A values. Security flaws or compliance gaps push prices down. Sometimes they kill deals entirely.
Due diligence uncovers potential compliance gaps. GDPR violations, HIPAA requirements, PCI DSS standards, SOX controls. The financial and reputational impact can derail transactions.
I've seen acquirers walk away from otherwise strong companies because the security posture was weak. No multi-factor authentication across the organization. No encryption at rest for customer data. No incident response plan. No third-party risk management.
These aren't theoretical concerns. They're balance sheet risks. A single breach can cost millions in remediation, regulatory fines, and customer churn. Acquirers price that risk into their offer or require escrow holdbacks until you fix it.
At Vaultinum, 97 percent of CIOs have seen technology due diligence uncover issues or opportunities that made a material impact on the deal. A well-executed technology review identifies both risks and opportunities for value creation. It offers clarity on the financial implications of technology initiatives, allowing acquirers to forecast the cost of ownership more accurately.
Common Security Red Flags
No multi-factor authentication across the organization
No encryption at rest for customer data
No incident response plan
No third-party risk management
Compliance gaps in GDPR, HIPAA, PCI DSS, or SOX
Bottom Line: Security vulnerabilities are balance sheet risks that acquirers price into offers or use to justify walking away from otherwise strong deals.
What SaaS Metrics Do Acquirers Scrutinize?
For SaaS companies, specific metrics tell the complete story. If your monthly recurring revenue, churn rate, or customer acquisition cost numbers don't line up across financial statements, dashboards, and bank records, buyers see this as either poor reporting or potential revenue manipulation.
When 40 percent of revenue comes from two enterprise contracts, a single cancellation can sink growth. This makes recurring revenue fragile. Churn rate under 5 percent monthly is typical for SMB SaaS. Less than 2 percent is better for enterprise. Most SaaS businesses aim for 70 to 90 percent gross margin. Below 60 percent raises red flags.
These metrics directly impact valuation and buyer confidence. Acquirers will model out different scenarios. What happens if your top three customers leave? What does unit economics look like at scale? How much does it cost to serve each customer segment?
Focusing heavily on acquisition without a strong ideal customer profile framework can lead to overselling and early churn. This hurts retention metrics and hampers future upsell potential. Poor fit customers may also distort feedback loops, making it harder to build the right product.
Key SaaS Benchmarks
Churn rate: Under 5 percent monthly for SMB SaaS, under 2 percent for enterprise
Gross margin: 70 to 90 percent typical, below 60 percent raises red flags
Customer concentration: Over 40 percent revenue from two contracts creates fragile recurring revenue
Unit economics: Must demonstrate positive economics at scale across customer segments
Critical Point: When metrics don't reconcile across financial statements, dashboards, and bank records, acquirers see poor reporting or potential revenue manipulation.
How Does Customer Concentration Impact Valuation?
Losing a major customer relationship after acquisition is a real possibility that deal teams must consider. Relying on one vendor to provide materials or products means any price increases could cut margins considerably, especially when seeking to scale operational capacity beyond your current level of demand.
I've watched deals get repriced because the target had 60 percent of revenue concentrated in three accounts. The acquirer modeled a scenario where those accounts churned within 18 months. The purchase price dropped by 35 percent to account for that risk.
Customer concentration creates negotiating leverage for the buyer. It also creates integration risk. If key customers signed contracts with your company because of personal relationships or specific team members, those relationships may not transfer smoothly post-acquisition.
The Math: Revenue concentrated in three accounts led to a 35 percent purchase price reduction in one deal because the acquirer modeled an 18-month churn scenario for those accounts.
What Is Sell-Side Technical Due Diligence?
Sell-side technical due diligence is commissioned by the company preparing for a sale. You identify, fix, or transparently disclose technical issues before buyers arrive. This creates a cleaner story, reduces last-minute surprises, and often improves valuation and deal speed.
Performing due diligence upfront uncovers weaknesses. It makes it easier to close gaps, improving your company's appeal and potentially leading to better valuation and smoother negotiations. This proactive approach demonstrates operational maturity and reduces acquirer risk perception.
According to Ernst & Young, 73 percent of companies that successfully integrate technology in M&A deals involve their technology integration leadership early in the due diligence process. This timing is critical. Acquirers with strong managerial experience or high-quality advisors have 62 percent higher chances of integrating IT functions successfully.
For companies without a CTO or CISO, this represents a significant disadvantage. Unless you bring in fractional leadership during the preparation phase, you're negotiating blind.
Benefits of Early Preparation
Identify and fix technical issues before buyers arrive
Reduce last-minute surprises that delay or kill deals
Improve valuation through demonstrated operational maturity
Create negotiating leverage by addressing weaknesses proactively
Accelerate deal speed with clean data rooms and documentation
Timing Insight: Companies that involve technology leadership early in due diligence have 62 percent higher chances of successful IT integration and 73 percent report successful technology integration overall.
How Do Acquirers Evaluate AI Capabilities?
Big strategic acquirers and private equity firms are back in the hunt, especially for deals that fit their growth themes. AI, cloud, and cybersecurity are at the top of the list. But they're conducting more thorough due diligence and being more selective.
Acquirers and regulators will scrutinize AI-related risks like data usage and model ethics during due diligence. This scrutiny is especially rigorous for AI and data companies.
You need to demonstrate not just AI features but production-ready implementations with clear data foundations. What data are you using to train models? Do you have the rights to use that data? How do you handle bias and fairness? What happens when a model makes a wrong prediction?
I've seen companies tout their AI capabilities only to reveal during diligence that they're using third-party APIs with no proprietary models, no unique datasets, and no differentiated algorithms. That's not AI. That's integration work. Acquirers price it accordingly.
AI Due Diligence Checklist
What data are you using to train models?
Do you have the rights to use that data?
How do you handle bias and fairness?
What happens when a model makes a wrong prediction?
Are implementations production-ready with clear data foundations?
Reality Check: Acquirers distinguish between production-ready AI with proprietary models and simple third-party API integration, and they price accordingly.
How Should You Prepare for Tech Due Diligence?
If you're building a company you might sell one day, operate as if you're always under scrutiny. Maintain high standards of operational excellence, data integrity, and legal compliance. This proactive approach increases your attractiveness to potential acquirers and improves your overall performance.
Start by documenting everything. Your architecture decisions, your security controls, your compliance efforts, your vendor relationships. Create a data room that's ready to open on day one of diligence.
Fix what you can fix now. Technical debt, security gaps, compliance issues. These problems don't age well. They compound. Address them before they become negotiating points.
Get an outside perspective. Bring in a fractional CTO or CISO to run a pre-diligence audit. Find the issues before the buyer does. You'll either fix them or prepare a clear explanation with a remediation plan and cost estimate.
Track the metrics that matter. For SaaS companies, that means MRR, churn, CAC, LTV, gross margin, and customer concentration. Make sure these numbers reconcile across all your systems. If they don't, you have a data quality problem that will surface during diligence.
Build relationships with your key customers and vendors. Document those relationships. Show that they're transferable and not dependent on individual personalities. This reduces perceived risk and protects your valuation.
Preparation Checklist
Document everything. Architecture decisions, security controls, compliance efforts, vendor relationships. Create a data room ready for day one.
Fix issues now. Technical debt, security gaps, compliance problems compound over time and become negotiating points.
Get outside perspective. Bring in fractional CTO or CISO to run pre-diligence audit and find issues before buyers do.
Track key metrics. For SaaS, reconcile MRR, churn, CAC, LTV, gross margin, and customer concentration across all systems.
Build transferable relationships. Document customer and vendor relationships to show they don't depend on individual personalities.
The Outcome: Operate as if you're always under scrutiny because this proactive approach increases acquirer attractiveness and improves overall performance.
The Bottom Line
Technology due diligence is not a formality. It's a value discovery process that determines whether your deal closes at the number you want.
The companies that prepare well get better outcomes. They negotiate from strength because they've already identified and addressed the issues that would otherwise become deal terms.
The companies that skip preparation pay for it. They face price reductions, escrow holdbacks, earnout structures, and post-close integration nightmares that drain value for years.
You can't fake operational maturity during diligence. You either built it into your company from the start, or you didn't. The acquirer will find out which one is true.
If you're planning an exit in the next 12 to 24 months, start preparing now. Run your own diligence. Fix what's broken. Document what's working. Build the operating system that makes your technology a growth engine instead of a liability.
That's how you protect your valuation and close the deal you want.
Frequently Asked Questions
