Commercial Due Diligence

Test the assumptions carrying the deal.

Contact Us

Investment cases usually fail on an untested assumption, not on headline growth. Common examples are demand that is expected but not yet contracted, a competitive advantage that rivals can copy, and a supply constraint that does not hold up.

We test the investment case with primary research and bottom-up analysis, and give a clear recommendation: proceed, reprice, add conditions or walk away.

We support buyers with buy-side due diligence, and sellers and their advisors with vendor assistance and vendor due diligence.

What we do

The questions we answer

We focus on the questions that can change the investment decision:

  • Is the market as large and as lasting as management assumes?
  • How much revenue is contracted, and how much is pipeline?
  • What alternatives can customers switch to?
  • Is the company's advantage hard to copy, or easy to replicate?
  • How will AI-native competitors affect its position during the hold period?

We answer these questions with primary research: interviews with customers, prospects, channel partners and industry experts, not management’s view alone.

Why Wykeham

Built for deal timelines

  • Partner-led from start to finish

    The Partner who scopes the engagement leads the analysis and signs off the final recommendation. We do not use junior teams.

  • Industry and subject-matter expertise

    Each team includes senior strategy consultants and a Domain Specialist from your industry.

  • Evidence and assumptions you can check

    Every key conclusion is linked to its source, and every key assumption is stress-tested, so your investment committee and board can make the decision and defend it.

  • Fixed scope and fee

    Scope, timeline, fee and deliverables are agreed upfront. We charge for the deliverable, not for consultant time.

  • A clear recommendation

    The final report states what holds up, what changes the economics, and whether to proceed, reprice, add conditions or walk away.
