Technical Due Diligence Services for Investors & Acquirers
Independent, thorough technical due diligence for venture capital firms, private equity, angel investors, and acquiring companies. We audit code quality, architecture scalability, security posture, technical debt, and team dependency risk — delivering a clear, actionable investment report in 7 to 14 days.
⚡A polished pitch deck and high revenue growth can easily mask crippling technical debt, brittle architecture, security vulnerabilities, or single-developer key-person risk.
As an independent technical auditor and fractional CTO with over 15 years of software engineering and systems architecture experience, I look beneath the surface. I review code repositories, inspect database schemas, interview lead engineers, and evaluate infrastructure costs to give investors an unbiased picture of what is actually running in production.
Whether you are an investor assessing a seed-to-Series B startup, a private equity firm evaluating an acquisition target, or a founder preparing for a funding round, my technical due diligence report provides the objective evidence you need to price risk accurately and negotiate terms with confidence.
Why Technical Due Diligence Protects Your Capital
Financial due diligence examines historical numbers. Technical due diligence examines whether the product can support future revenue without collapsing. Here are the costly investment traps we uncover:
Hidden Refactoring Costs & Scalability Ceilings
A software product that runs fine on 1,000 customers may require an emergency $300k architectural rewrite to reach 50,000 users. We evaluate execution plans, monolithic bottlenecks, and database schemas to uncover hidden re-engineering expenses before you invest.
Severe Key-Person Dependency Risk
If the entire product's architecture exists solely in the head of one solo developer or an offshore contractor who might leave after the acquisition, your investment carries massive delivery risk. We assess team documentation, knowledge transfer, and bus factor vulnerability.
Security Holes, Compliance & Regulatory Exposure
Unpatched dependencies, hardcoded API secrets, unencrypted PII, and lax access control policies can lead to devastating post-close security breaches and regulatory fines. We audit against industry security baselines including OWASP, SOC 2, and GDPR readiness.
IP Ownership & Open-Source License Contamination
Copyleft open-source licenses (GPL, AGPL) accidentally embedded into proprietary codebases can force companies to open-source their intellectual property. We scan dependency trees and employment agreements to verify clean IP ownership.
Runaway Cloud Hosting & Infrastructure Waste
Founders often mask slow queries by throwing over-provisioned AWS/GCP servers at the problem. We evaluate infrastructure utilization, identifying overspending and projecting true hosting unit economics as customer volume scales.
Objective Valuation & Deal Negotiation Leverage
Uncovering concrete technical debt or compliance gaps gives buyers strong negotiating leverage to adjust valuation, establish post-close escrow holdbacks, or require sellers to remediate critical flaws prior to funding.
The 6 Pillars of Our Technical Due Diligence Audit
An exhaustive, multi-dimensional assessment evaluating every layer of the target company's technology stack.
1. Code Quality, Architecture & Scalability
Inspect the code for architectural integrity, modularity, readability, and test coverage.
- Analyzing code structure, separation of concerns, and cyclomatic complexity.
- Automated test coverage (unit, integration, end-to-end) and build stability.
- Evaluating API design, service boundaries, and asynchronous event architectures.
- Assessing whether the application can scale 10x without fundamental re-architecting.
2. Database Architecture & Data Integrity
Assess data models, query latency, schema normalization, and backup resiliency.
- Reviewing relational schema models — see our Database Architecture standards.
- Profiling slow queries and indexing — see our Database Optimization Services.
- Verifying automated database backup schedules, replication, and disaster recovery RTO/RPO.
- Evaluating data migration history and schema version control hygiene.
3. Cloud Infrastructure & Cost Efficiency
Audit cloud hosting configurations, containerization, and monthly infrastructure spend.
- Evaluating AWS, Azure, or GCP cloud architecture, autoscaling, and VPC topologies.
- Reviewing Docker containerization, Kubernetes configurations, and Terraform IaC hygiene.
- Analyzing cloud hosting cost efficiency and projecting infrastructure cost per active user.
- Auditing CI/CD deployment pipelines, automated rollbacks, and release frequency.
4. Cybersecurity & Regulatory Compliance
Identify vulnerability exposures, access control weaknesses, and regulatory gaps.
- Auditing authentication mechanisms (SSO, MFA, session management, password hashing).
- Role-Based Access Control (RBAC), tenant data isolation, and API endpoint permissions.
- Evaluating encryption in transit (TLS) and encryption at rest for sensitive customer data.
- Reviewing compliance alignment for SOC 2, HIPAA, GDPR, and PCI-DSS readiness.
5. IP Ownership & Open-Source License Risk
Verify clean intellectual property ownership and identify license contamination hazards.
- Automated dependency scanning for high-risk viral licenses (GPL, AGPL, SSPL).
- Verifying that all contractor and employee code assignments are legally assigned to the company.
- Auditing third-party SaaS API dependencies, single-vendor lock-in, and renewal costs.
- Checking for unmaintained, abandoned, or deprecated open-source packages.
6. Engineering Team Capacity & Key-Person Risk
Assess developer velocity, engineering culture, and institutional dependency risks.
- Confidential technical interviews with engineering leadership and senior developers.
- Assessing documentation thoroughness (architecture runbooks, onboarding guides, API docs).
- Evaluating sprint delivery velocity, bug triage cadence, and release predictability.
- Identifying single points of failure (developers whose departure would halt operations).
Critical Technical Red Flags We Uncover
Issues that routinely alter deal valuations, escrow terms, or investment decisions:
Deal-Breakers & Valuation Impacts
- ✕ Critical security flaws (unauthenticated admin endpoints, unencrypted credentials).
- ✕ AGPL/GPL copyleft license contamination inside proprietary commercial modules.
- ✕ Contractors who wrote core algorithms without signing IP assignment agreements.
- ✕ Total lack of automated backups or untested disaster recovery procedures.
Operational Friction & Post-Close Debt
- ✓ Extreme technical debt requiring substantial post-close developer refactoring.
- ✓ Single-person key risk with no documentation or secondary domain knowledge.
- ✓ Inefficient database queries causing 5x higher AWS/RDS hosting bills than necessary.
- ✓ Absence of automated testing suites leading to frequent production regressions.
A technical audit is not about finding reasons to kill a deal. It is about giving investors clear, objective visibility into technical risks, remediation costs, and operational timelines so you enter the transaction with eyes wide open.

Frequently Asked Questions About Technical Due Diligence
FAQ & Key PointsQWhat is technical due diligence and who needs it?
Technical due diligence is an independent audit of a software company's technology assets, code quality, infrastructure, security, and engineering team. It is typically commissioned by venture capital funds, private equity firms, angel investors, or acquiring companies during an M&A transaction or investment round. Founders also commission pre-sale audits to identify and fix red flags before going to market.
QHow long does a technical due diligence audit take?
A standard audit is completed in 7 to 14 business days, depending on codebase size, repository count, and responsiveness of the target engineering team. For rapid deal cycles, expedited 5-day sprints are available upon request.
QWhat access is required from the target company?
We require read-only access to code repositories (GitHub/GitLab/Bitbucket), architecture documentation, and cloud console metrics (AWS/GCP/Azure). In addition, we conduct a 60-minute structured interview with the target CTO, lead architect, or engineering manager. We operate under strict mutual non-disclosure agreements (NDAs).
QHow does technical due diligence help in deal negotiation?
By identifying concrete issues—such as $150k in required database refactoring, unpatched security vulnerabilities, or GPL license risks—investors can adjust valuation, request specific indemnity clauses, require holdbacks in escrow, or make remediation a condition precedent (CP) before funds are disbursed.
QDo you assess early-stage startups or only mature companies?
We audit technology across the maturity spectrum: from pre-seed / seed startups validating MVP architecture to growth-stage Series A/B SaaS companies and established mid-market enterprises undergoing acquisition. The audit scope and expectations are calibrated appropriately for the company's stage.
QCan you assist with post-acquisition engineering remediation?
Yes. Many investors and acquirers retain me as a fractional CTO post-close to oversee the implementation of the remediation roadmap, guide developer hiring, or supervise the integration of the acquired technology into the parent company.
