Technical Due Diligence

Asset-grade systems assessment for acquirers, investors, and boards evaluating post-PMF software businesses.

Deal-oriented findings quantified in cost and timeline AI-generated code evaluation and verification audit Architecture, security, and scalability read Executive summary for investment committees NDA-ready, deal-sensitive workflow

Asset-grade assessment for acquirers.

You are about to transact on software. The pitch deck says the product works. The founder says the architecture is sound. Revenue says the business is real. None of that tells you whether the asset you are buying will carry the next five years of load, hiring, and regulatory scrutiny.

Technical Due Diligence tells you. We read the system the way an operator would read it, with the deal context, the valuation thesis, and the time pressure of a transaction, and return a report your investment committee can act on.

Different from a developer audit

A developer audit optimizes for what to fix. Our diligence optimizes for what to transact on.

  • Findings are quantified in remediation cost and integration timeline. The numbers you need to adjust valuation, structure earnouts, or walk away.
  • The executive summary is written for non-technical decision-makers on the investment committee.
  • We work under NDA, in data-room conditions, alongside legal and commercial diligence teams.
  • We can deliver a focused assessment in as little as one week when deal timing requires it.

What we evaluate

  • Architectural soundness and the scalability ceiling at 10× the current load
  • AI-generated code exposure: how much of the codebase it represents, how it was supervised, and what liability it introduces
  • Security posture, compliance readiness, and audit trail quality
  • Dependency and supply-chain risk
  • Operational maturity: CI/CD, observability, deploy safety, key-person exposure
  • Verification debt and team capacity to carry the codebase post-transaction

Typical engagements

  • Growth equity and PE diligence on software acquisitions in the $5M to $100M range
  • Pre-Series B/C investor diligence to validate that the technology behind the deck is real
  • Portfolio-company bolt-on acquisitions
  • Corporate development build-vs-buy evaluations

What you get

A deal-oriented report with quantified findings. An executive summary for the investment committee. An architecture diagram of the system as it actually is. A remediation roadmap with cost and timeline estimates. A call with the deal team to walk through implications.
