Technical Due Diligence

Technical due diligence for software investments.

Independent, read-only review for investors and acquirers. Each material finding links evidence to the investment thesis, deal exposure, and the action required.

The decision

Translate the system into deal consequences.

A software target can pass a demo and still miss the deal thesis. Technical due diligence tests whether the deployed system, delivery team, operating controls, and cost base can support the buyer's growth and integration plan.

The work begins with the investment thesis and the decisions still open. Those questions determine the evidence request. A product-led SaaS acquisition, a minority growth investment, and a regulated carve-out do not need the same review.

Interviews explain how the company believes its system works. Repositories, infrastructure, records, contracts, logs, invoices, and operating evidence show what can be verified.

Missing access remains a limitation. It is never converted into a green score. The decision memo separates verified facts, management statements, reviewer inference, and open evidence so the investment committee can judge confidence.

We have no economic interest in a recommended vendor or later remediation. Any implementation work after the transaction is separately scoped and approved.

Engagement fit

Use the right review for the decision at hand.

Technical DD fits

A transaction depends on technology

Use this engagement when software, data, infrastructure, or the engineering team is material to value, integration, growth, resilience, or exit.

  • VC, growth-equity, or private-equity investment in a software company
  • Corporate acquisition of software, a platform, data assets, or a technology-enabled business
  • Pre-close validation of a technology value-creation or integration plan
  • Founder-side preparation against a known investor evidence request
Choose another route

The decision needs a different specialist

Legal, financial, commercial, privacy, and offensive-security specialists remain responsible for their workstreams. Technical diligence can coordinate those findings while leaving each conclusion with the qualified owner.

  • Use a technical audit for internal improvement with no transaction
  • Use a penetration test for exploit-focused security testing
  • Use legal and privacy counsel for legal interpretation
  • Use the evidence checklist when the immediate job is data-room preparation
Deal questions

Five questions the system must answer with evidence.

Architecture diagram review for scalability assessment

Does the product support the investment thesis

Can the current architecture, product boundaries, and delivery model support the growth, market, and integration assumptions in the deal?

Security, resilience, and technical privacy evidence review

What could interrupt revenue or trust

Which security, resilience, privacy, access, recovery, or incident exposures could affect customers, operations, insurance, or contractual commitments?

Cloud cost and unit economics analysis

Can the team keep delivering

Where do code ownership, review practice, release controls, documentation, on-call coverage, and key-person concentration constrain the plan?

Technical debt map and ownership review

What will growth and integration cost

Which cloud, licence, data, migration, re-platforming, and remediation costs belong in the value-creation plan or purchase assumptions?

Vendor dependency and lock-in risk assessment

What does the buyer actually control

Who owns the code, data, accounts, domains, models, licences, and critical vendor relationships, and what happens if a supplier or key person leaves?

Scope note mapping the investment thesis, open decisions, target shape, access plan, exclusions, and deadline
Evidence register showing what was requested, received, verified, contradicted, inferred, or still missing
Material finding cards with severity in deal context, confidence, exposure, evidence, and action
Decision memo for the investment committee, separating pre-close conditions, price or plan inputs, post-close priorities, and monitoring items
Sequenced 30-, 90-, and 180-day technical action plan where the transaction requires post-close work
Evidence standard

Every material finding must be traceable.

Each finding records the deal assumption tested, evidence inspected, result, confidence, exposure, action, and any limitation. The review asks for the smallest access needed to reach a defensible conclusion.

Repository, commit history, build and release evidence for ownership and delivery claims
Architecture, infrastructure configuration, cloud inventory, logs, backups, and restore evidence for scale and resilience
Dependency manifests, software-component records, vulnerability state, patch history, and accepted exceptions for supply-chain exposure
Data maps, processor and vendor records, access controls, retention settings, and incident history for the technical privacy posture
Cloud invoices, usage exports, licence obligations, and capacity assumptions for the operating-cost model
Team interviews checked against review history, runbooks, on-call records, release evidence, and key-person concentration
Explicit access and time limitations, including evidence requested but unavailable before the decision deadline
Questions for the scope call

What we establish before requesting access.

A short scope call should narrow the review before anyone opens a data room. These answers control depth, specialists, timing, and evidence.

  • 01What part of the investment thesis depends on the product, data, or engineering team?
  • 02Which decisions must the diligence change: proceed, price, condition, integrate, fund, or monitor?
  • 03What is the target shape: SaaS product, marketplace, data business, AI system, carve-out, or technology-enabled service?
  • 04Which jurisdictions, regulated activities, customer commitments, and buyer policies shape the technical questions?
  • 05What access can be granted, to whom, under what confidentiality controls, and by which decision deadline?
FAQ

Questions about technical due diligence.

What does technical due diligence cover?

The scope follows the investment thesis. It commonly tests product and architecture fit, security and resilience, engineering delivery, operating economics, data and vendor dependencies, ownership, and integration exposure. A software acquisition and a technology-enabled services company require different evidence.

How long does technical due diligence take?

The schedule is set after the transaction stage, target shape, open decisions, access, specialist needs, and investment-committee deadline are known. The scope note states what can be verified in that window and what will remain a limitation. We do not promise a universal duration before those facts are available.

What is the difference between a technical audit and technical due diligence?

A technical audit is typically commissioned by the company itself for internal improvement. Technical due diligence is conducted by or for an investor or acquirer to assess commercial and technical risk before a transaction closes.

Can a founder commission their own technical due diligence before fundraising?

Yes. Founder-side work should be identified as pre-DD or readiness work so the later investor review remains independent. Start with the technical due diligence evidence checklist to identify missing records and ownership before deciding whether an external review is needed.

Which standards inform the security and dependency review?

We use standards to structure questions; they do not substitute for transaction evidence or certification. NIST SP 800-218 informs secure-development evidence, CISA SBOM resources inform software-component transparency, and OWASP SAMM informs lifecycle practice. For an in-scope financial entity, DORA may add ICT third-party questions. Legal counsel determines applicability and legal conclusions.
