Technical due diligence for investors and founders

An independent assessment of the product, code and team before an investment, a deal, or joining a project. I answer one question: how technically sound is what you're being offered, what are the risks, and what do they cost.

When companies bring me in

  • You’re about to invest in or acquire a company and want to know what has actually been built.
  • The pitch is convincing, but there's no one to check the technical side.
  • You need to know whether the product will withstand the growth in the business plan.
  • The team says everything is fine, but you want an independent view.
  • The deal is close and you have weeks, not months, to check.

What you get

  • A clear conclusion: whether to invest, what the risks are and what they cost.
  • Findings sorted by impact on the deal, not by academic correctness.
  • An estimate of what needs fixing, on what timeline and at what cost.
  • A conversation in business language — no "microservices" or "legacy" where it doesn't affect your decision.

How I work

  1. First we establish what is critical in your particular deal; that sets the depth and focus of the review.
  2. I look at five things: the architecture and its ability to carry the planned growth; technical debt and its effect on the pace of change; the team and dependence on key people; processes, infrastructure and security; and whether what is built matches what is claimed.
  3. I turn the findings into a conclusion: the risks, their cost, what must be closed before the deal and what can be fixed after.
  4. We go through the result so that you make the decision yourself rather than take my word for it.
  5. Typical timeframe: from a few days to a couple of weeks, depending on the size of the product.

From practice

  • Cloud platform for fitness club chains — a product that went from a first version to raising investment: it shows from the inside what an investor looks at.

The exact figure is set once scope and depth are agreed.

  • What's included: an assessment across five areas — the architecture and its headroom for the planned growth; technical debt and its effect on the pace of change; the team and dependence on key people; processes, infrastructure and security; and whether what's built matches what's claimed. The result is a written conclusion with the risks, their cost and priorities.
  • Timeline: from a few days to two weeks, depending on the size of the product and the depth required.
  • Outcome: a written conclusion and a walkthrough of the findings.

FAQ

How long does it take?
From a few days to a couple of weeks, depending on the size of the product and the depth you need.
Do you need access to the code?
Preferable, but a lot is visible without it: architecture, processes, the team, and whether the product matches what's claimed. I work with whatever level of access you can give.
What if the team resists the review?
That is a signal in itself. Resistance usually fades once it's clear the goal isn't to find someone to blame but to understand the risks.
What about confidentiality?
An NDA is standard. Nothing I see leaves the room, including my public materials.
Will you fix what you find?
Not necessarily, and I don't push for it: the independence of the assessment matters more than continuing the work.
