About This Service

How We Deliver
Technical Due Diligence

We review architecture, code quality, security, scalability and team practices, then hand you a plain-English report: what’s solid, what’s fragile, what the real remediation cost is, and whether it can carry the growth you’re underwriting. Useful to the people writing the cheque and the founders taking it.

Pain Points

Why most teams stall before they see results

The patterns we see across new audits — and the fixes baked into every engagement.

Hidden technical risk in a deal

Investors and acquirers can't see the real state of the tech. We surface the risks before the deal closes.

Undisclosed technical debt

Debt and shortcuts hide behind a working demo. We assess what's really under the hood.

Scalability and team unknowns

Can the tech and team actually scale? We evaluate architecture, practices and capability.

Security and compliance exposure

Undiscovered security or compliance gaps become liabilities. We identify them in diligence.

Our Process

How we ship Technical Due Diligence

A proven 4-step framework that compresses time to results without cutting corners.

01

Assess the real state

An independent, expert review of codebase, architecture and technical debt behind the demo.

02

Evaluate scalability

We assess whether the architecture and team can support the plan, and scope remediation.

03

Surface security & compliance

We identify security and compliance exposure before it becomes the acquirer's liability.

04

Report for the deal

A clear findings report with risks, scalability and remediation to inform valuation.

01Independent assessment of the technology
See the real state

Independent assessment of the technology

A working demo tells an investor or acquirer almost nothing about the real state of the technology — the risks live under the hood. We provide independent technical due diligence: an expert, honest assessment of the codebase, architecture, technical debt and engineering practices, so you understand what you're actually buying or funding. A clear-eyed independent assessment is what turns a technology black box into an informed decision.

  • Codebase and architecture assessment
  • Technical-debt and shortcut evaluation
  • Engineering-practice and quality review
  • Honest, independent findings
02Can it — and the team — actually grow?
Scalability & risk

Can it — and the team — actually grow?

The questions that matter in diligence are forward-looking: will the architecture scale, is the technical debt manageable, can the team deliver, what will it cost to fix. We evaluate scalability, key risks, and team capability, and quantify what remediation would take, so the technical picture informs valuation and post-deal planning. Assessing scalability and risk is what tells you not just what the tech is, but whether it can support the plan.

  • Scalability and architecture-risk assessment
  • Technical-debt remediation scoping
  • Team capability and practice evaluation
  • Findings that inform valuation and planning
03Surface the exposures before they're yours
Security & compliance

Surface the exposures before they're yours

Undiscovered security vulnerabilities and compliance gaps become the acquirer's liability the moment the deal closes — so diligence has to surface them. We assess security posture and compliance exposure (data handling, vulnerabilities, regulatory gaps), so risks are known and priced before they become your problem. Surfacing security and compliance exposure in diligence is what prevents a post-close surprise from becoming a costly liability.

  • Security-posture assessment
  • Compliance and data-handling gap review
  • Vulnerability and exposure identification
  • Risks known and priced pre-close

FAQs

Questions buyers ask before signing

Quick answers to the things buyers always check first.

What is technical due diligence?
An independent, expert assessment of a company's technology for investors or acquirers — the codebase, architecture, technical debt, scalability, team capability, and security/compliance exposure — so you understand the real state and risks of what you're buying or funding, beyond a working demo.
Why can't a demo tell us what we need?
Because a working demo reveals almost nothing about what's under the hood — technical debt, architectural risk, scalability limits and security gaps hide behind a functioning product. Diligence surfaces the real state so it informs valuation and post-deal planning.
What do you assess?
Codebase quality and technical debt, architecture and scalability, engineering practices, team capability, and security and compliance exposure — with the risks quantified and remediation scoped, so the technical picture is clear and actionable.
How long does technical due diligence take?
Typically 1–3 weeks depending on the size and complexity of the technology and the depth required, delivered as a clear findings report with risks, scalability assessment and remediation scoping.
