Technology Due Diligence
Technical due diligence services are important for a successful M&A deal, on both sides of the table. Your software’s condition determines your company’s value, or the value of a target you’re buying.
We evaluate the codebase, architecture, security, and scalability to identify buyer concerns and modernize the areas that most affect deal outcomes.

Let us help you rebuild what’s holding you back.
We provide an end-to-end software due diligence service for both sides of a deal, delivering the most accurate, multi-dimensional evaluation of your software system to support your strategic decisions with technical insights.
Our technology diligence services cover both sides of the deal, enabling buyers to invest with a full understanding of the system, and sellers to detect and address issues that would lower the price.
Evaluate the underlying technology — compare actual system capabilities with the seller’s statements about performance, scalability, and security
Identify the technical debt and AI-generated code — highlight areas that can complicate maintenance and slow down the engineering process, even if code passes linters
Сheck the licences and third-party dependencies — make sure that there are no terms that restrict how you can use, scale, or sell the product
Detect knowledge silos — examine how expertise is distributed inside the team and assess the risk of disruption in case a critical knowledge holder leaves the team after the deal
Estimate maintenance costs and resources for required improvements — strengthen your negotiation position and build a more accurate post-acquisition plan
Prioritize tasks to get ready for the deal — decide what issues to address before going to market and what to include in the remediation plan
Enhance technical documentation — provide a relevant, detailed description of the system’s architecture, dependencies, and setup specifics to minimize the number of open questions during the technical review
Make critical knowledge accessible — document essentials known only to several team members to eliminate the buyer’s concerns related to key-person dependency
Prove the system’s growth potential with measured evidence — deployment frequency, change failure rate, and recovery time
Ensure your operational continuity during audit — we work inside your Git and CI/CD with minimal interference
We produce the architecture, dependency, and setup docs many legacy systems lack, so ownership hands off cleanly and holds its value.
Technical due diligence for sellers raising valuation and buyers vetting a target — the same evidence, whichever side you’re on.
We aren’t a full-stack agency. We’ve built our team, processes, and tech strategy specifically to tackle legacy issues and help mid-market players scale and innovate.
We integrate with your workflows, minimizing interference with your developers. While utilizing your Git, CI/CD, and tools, we operate independently, letting your team focus on their work.
We remove legacy barriers preparing your systems for advanced tech. You can embrace new tools with the future-ready and ROI-driven architecture.
We treat your system efficiently: evolve the functioning parts and replace only the ones that require change.
We start with a deep evaluation of your business challenges, relevant needs, and strategic goals. It helps clarify the specifics of your product and its alignment with core business tasks to ensure the quality of subsequent due diligence stages.
The Corsac experts provide a comprehensive review of your system design and codebase health. From architectural concerns to hidden dependencies, complexities, and duplications, you’ll get a full understanding of your system stability to set realistic valuation expectations.
Assess infrastructure stability and readiness for post-acquisition growth
Evaluate operational efficiency to optimize resources and reduce delivery risk
Check compliance posture to avoid penalties and prolonged transactions
Detect bottlenecks and hidden risks, and flag the ones that most affect deal value
Provide a well-structured roadmap to strengthen your technical position before the deal
We analyze your software weaknesses and prioritize risks by their severity and business impact. This enables quick reaction to critical issues, creation of reliable long-term protection plans, and increased confidence for strategic transactions.
Book an expert consultation to uncover gaps in your system. Let us modernize your business to its maximum potential.
Give your stakeholders a concise summary with a clear overview of technical findings, not overwhelming details. We trace each conclusion to the underlying code, configuration, or team interview so that it can be easily validated.
Get a clear illustration that helps you understand how modules, databases, and third-party components are related to each other and evaluate the impact of changes. Vendor lock-in and unsupported libraries are also visualized.
We assess the likelihood and business impact of detected risks, helping understand the urgency and type of mitigation measures. Additionally, the items are classified as factors that can break the deal, affect the price, or require post-acquisition remediation.
Based on software due diligence findings, we group tasks into phases with defined milestones. You’ll be able to allocate resources correctly, focusing on important pre-deal improvements first and planning non-critical tasks.
Support board decisions with a transparent breakdown covering scope, effort, expected budget, and cost drivers behind each phase. Compare alternative investment scenarios to remove uncertainty from the negotiation process.
Streamline corrective measures with a structured action plan, assigned owners, clear timeline, and escalation criteria. Enable your team to address risk at its root without additional planning.

Technical due diligence services are needed to get a multi-dimensional, unbiased assessment of your system’s health. If you’re planning an important M&A or investment decision, or going to scale, such a service will help you understand your system’s strengths and weaknesses, as well as identify ongoing issues and potential risks.
Technical due diligence is similar to a traditional software audit that covers business context review, code base and architectural evaluation, security, infrastructure, and operational assessment. In addition, you’ll get a team and delivery process review and an investment risk analysis with expert recommendations.
Absolutely. Software due diligence is one of the most crucial preparation steps before such an important decision. It’ll help you not just better understand what lies behind your software, but also implement the necessary improvements early in the process and maximize your company’s value before the deal.
We follow a two-phase approach. First, we conduct an engineering due diligence and provide you with a comprehensive, buyer-focused report. It includes key findings, ranked by their deal impact, and expert recommendations.
The second step is optional. We can cover all your modernization needs to maximize your company’s valuation and strengthen your market position.
You’ll get a detailed, well-structured, clear report that includes all the technical insights on software quality and a prioritized list of risks. It should be backed by a business-focused explanation that highlights how the technical environment can impact valuation and deal results.
