How Software Companies Can Get Due Diligence Ready
When a software company enters a transaction process, whether raising growth equity or pursuing an exit, the technical due diligence phase often becomes a stress test. Investors donât just want to understand what your product does; they want confidence that the technology powering your business can scale, adapt, and sustain value over time.
Too often, diligence uncovers surprises: missing documentation, brittle infrastructure, or security blind spots. These issues donât just slow the deal, they can impact valuation or even kill a transaction. The good news: with deliberate preparation, engineering leaders can turn diligence from a defensive exercise into a demonstration of strength.
Here is a Due Diligence Readiness Checklist for Software Companies
Hereâs how:
1. Documentation: Build the Single Source of Truth
Most diligence processes start with a âdata roomâ request list. If you canât respond quickly with clear, accurate materials, investors will assume there are deeper gaps in your technology organization.
Where to focus:
Architecture Diagrams: Create system-level and service-level diagrams that show how components interact, which technologies are used, and where data flows. Outdated whiteboard sketches or Visio files wonât cut it. Make sure diagrams reflect reality.
Infrastructure Inventory: Maintain an up-to-date list of all environments, cloud accounts, third-party services, and key dependencies. Investors want to know how complex your footprint is, how resilient it is, and where thereâs vendor lock-in.
Cloud vendor lock-in isnât always bad, itâs often a smart trade-off. At early and growth stages, using managed services accelerates time-to-market and reduces engineering overhead, which typically outweighs portability concerns. It becomes problematic when it limits customer adoption (e.g., multi-cloud requirements), erodes negotiating leverage, or makes future re-architecture prohibitively expensive. The key is to show investors youâve quantified the trade-off: lock-in is acceptable if it delivers efficiency today and you understand the cost to mitigate later.
Development Practices: Document your branching strategy, release cadence, and deployment workflow. If your team relies on tribal knowledge here, thatâs a flag for scalability risk.
Security Policies: Provide written policies covering authentication, encryption, incident response, and access management. Even if youâre not SOC 2 certified, showing disciplined governance earns credibility.
Action Step:
Treat documentation as part of your engineering asset base, not an afterthought. Well-maintained artifacts signal a disciplined culture.
2. Code Quality: Show, Donât Tell
Investors rarely read code but they do bring in specialists who will. The goal isnât to prove your code is âperfectâ (it never is), but to show that itâs manageable, maintainable, and improving over time.
Where to focus:
Testing Discipline: Document automated test coverage, unit/integration test ratios, and pass rates in your CI/CD pipeline. Low coverage isnât fatal, but lack of awareness is.
Static Analysis Metrics: Run SonarQube, CodeClimate, or equivalent tools to generate baseline quality reports. These should show trends, not just snapshots.
Technical Debt Register: Keep a prioritized list of intentional shortcuts or deferred refactors, along with remediation plans. Investors respect conscious trade-offs more than hidden landmines.
Coding Standards: Highlight consistency across teams. Show use of linters, style guides, and frameworks that minimize âcowboy coding.â
Action Step:
Run your own internal âmock diligenceâ code review six months before a deal. Address quick wins and prepare narratives for longer-term debt.
3. Cloud & Infrastructure: Demonstrate Maturity
Cloud operations are where scalability and resilience show or fall apart. Investors want to know if your architecture can handle growth without massive reinvestment.
Where to focus:
Cloud Architecture: Document redundancy, failover strategies, backup policies, and disaster recovery procedures. If your platform has single points of failure, highlight how youâre addressing them.
Observability: Showcase your monitoring, alerting, and logging stack. Investors want evidence that you catch problems early and resolve them quickly.
Cost Efficiency: Demonstrate how you track and optimize cloud spend (rightsizing, reserved instances, autoscaling). If your margins depend on infrastructure cost, this matters even more.
DevOps Maturity: Share metrics like deployment frequency, lead time to production, mean time to recovery, and rollback capability. These demonstrate operational excellence more than any PowerPoint could.
Action Step:
Align your infrastructure story to business growth. Be ready to answer: Can this platform support 5x more users without re-architecting?
4. Security & Compliance: Eliminate Unknowns
Security is no longer optional, itâs table stakes. Any hint of negligence here can cause an investor to pause or reduce valuation.
Where to focus:
- Pen Tests & Scans: Provide results from recent penetration tests, vulnerability scans, and remediation reports. An unaddressed backlog will be a red flag.
A penetration test (pentest) is a simulated cyberattack conducted by security professionals to identify vulnerabilities in your systems, applications, or infrastructure before real attackers can exploit them. Unlike automated scans, pentests use human-driven techniques to mimic how adversaries might breach defenses, escalate access, or exfiltrate data. The outcome is a report detailing exploitable weaknesses, their severity, and recommended remediations. This provides both a security baseline and proof of due diligence for customers and investors.
Access Controls: Show how you enforce least-privilege access, MFA, and role-based permissions. Static shared credentials or unmanaged SSH keys are instant credibility hits.
Compliance Alignment: Even if youâre not certified, demonstrate adherence to frameworks relevant to your market (SOC 2, ISO 27001, HIPAA, GDPR). Policies and audits show maturity.
Dependency Management: Track open-source licenses and vulnerabilities. A single GPL component in a proprietary product can create legal headaches.
Action Step:
Treat security hygiene like financial hygiene: measurable, recurring, and reportable. Investors assume discipline in one area reflects discipline in others.
5. Team & Process: Highlight Strength, Not Fragility
Investors assess not just the product, but the team that builds it. They want to know if your engineering organization is resilient and scalable or overly dependent on a handful of heroes.
Where to focus:
Org Structure: Provide a clear map of roles, responsibilities, and reporting lines. Call out where youâve reduced single-person dependencies.
Velocity Metrics: Share sprint throughput, release frequency, or cycle time trends not vanity metrics like âlines of code.â The goal is to demonstrate predictability.
Talent Strategy: Document your hiring funnel, onboarding plan, and retention stats. If youâre competing for scarce technical talent, investors will want to see how you plan to scale the team.
Culture & Practices: Showcase how you balance innovation with stability (e.g., code review practices, postmortem culture, or use of feature flags).
Action Step:
Anticipate âkey person riskâ questions. Investors will probe whether losing one engineer could cripple the product.
6. Product Roadmap: Align Technology with Business Value
Diligence isnât just about what youâve built. Itâs about where youâre going. Investors want to see that your technology strategy supports growth, not just survival.
Where to focus:
Scalability Roadmap: Show when and how youâll address scaling bottlenecks. For example: âWe can handle 2x traffic with current architecture; at 5x, weâll shard the database.â
Feature Prioritization: Connect roadmap items to revenue growth, customer retention, or competitive differentiation. Avoid âtech for techâs sake.â
Technical Debt Paydown: Highlight planned investments to improve velocity, not just new feature delivery. A roadmap with only features and no debt reduction feels brittle.
Innovation vs. Maintenance: Demonstrate a balanced portfolio of initiatives; some driving growth, others securing the foundation.
Thereâs no universal âperfectâ split because it depends on company stage, product maturity, and market pressures. That said, there are healthy benchmark ranges for growth stage companies that investors look for: Innovation around 50-65%, Maintenance 20-30%, and Tech Debt Reduction (15-20%).
Action Step:
Build a clear, business-aligned story: Hereâs what the next 18 months look like, why it matters commercially, and how the tech will deliver it.
Executive Takeaway
Technical due diligence isnât just about surviving scrutiny. Itâs a chance to prove that your engineering team is building a durable, scalable business asset.
For CTOs and engineering leaders, preparation is about discipline: having documentation that tells your story, metrics that validate your claims, and a roadmap that connects technology to business outcomes.
For executives and investors, the presence or absence of these signals becomes a proxy for valuation. A well-prepared company earns confidence, accelerates the deal timeline, and positions itself for faster post-close execution.
In short: readiness in engineering is readiness for the deal.
Itâs worth remembering that due diligence exercises shouldnât be viewed as contentious. It's not common that technical due diligence results in a deal being cancelled. More often, its purpose is to help buyers understand the asset theyâre acquiring so they can maximize its value post-close, whether through product expansion, operational improvements, or integration strategies.
