Test the thesis before you spend on the deal. Investment-grade research, run at origination, not after the term sheet.

The case for thesis validation

By the time a deal hits formal diligence, several million pounds of deal cost is already committed, bankers, lawyers, accountants, internal team time. Decisions about whether to proceed get heavily influenced by sunk cost. The right time to test the thesis is earlier, when the cost of breaking it is small.

Critical Deal investment-thesis engagements run at pipeline or origination stage, sometimes pre-exclusivity, sometimes during. The goal is to get to a verdict on whether the thesis holds before more substantial diligence cost is committed.

What we test

  • Market thesis. Is the category growing, stagnating or compressing? Tested against bottom-up sizing and buyer behaviour, not the analyst report.
  • Customer thesis. Are the target's customers really sticky, expanding, or about to churn?
  • Differentiation thesis. Is the edge durable in the eyes of the buyers, or is it a price story dressed up as a product one?
  • Team thesis. Can the leadership team execute the plan? Tested with peers, ex-colleagues, and senior hires of past employers.
  • Exit thesis. Who's the next buyer? Strategic, financial, IPO. What does that buyer need to see?

What we deliver

  • A thesis verdict, holds, partly holds, does not hold, with the assumptions ranked by exposure.
  • The red-flag log, items material enough that the IC should see them.
  • The buyer voice, anonymised interviews with the target's actual or candidate customers.
  • The market model, bottom-up sizing if part of the thesis.
  • An IC summary, short enough to insert directly into the paper.
How we run it

Five steps to a thesis verdict.

  1. Thesis decomposition.

    We translate the IC paper into its component claims, market, customer, edge, team, exit.

  2. Buyer interviews.

    The target's customers and candidates, anonymised, screened, recorded.

  3. Competitive read.

    What's actually happening in the comp set the IC is worried about.

  4. Market model.

    Bottom-up sizing where the thesis depends on category growth.

  5. IC-grade verdict.

    Holds, partly holds, or does not hold. Plus the red-flag log.

The right time to test a thesis is before the deal cost, not after.

Frequently asked

Investment thesis validation, questions.

What's investment thesis validation?

Research undertaken to test the claims at the heart of an investment thesis before capital is committed. The output sits inside the IC paper and informs the vote.

How is it different from commercial due diligence?

CDD is run inside a deal window, after exclusivity, often under time pressure. Thesis validation runs earlier, at pipeline or origination stage, when the goal is to break the thesis cheaply before significant deal cost is incurred.

Who commissions it?

PE growth and buyout funds, late-stage VC, family offices, debt providers, and corporate development teams running serial acquisition strategies.

How long does it take?

Two to six weeks depending on thesis complexity. Light first-look engagements: 5–10 working days.

What does it cover?

The market thesis (is the category really doing what the deck says?), the customer thesis (are customers really sticky?), the differentiation thesis (is the edge durable?), the team thesis (can they execute?), and the exit thesis (does the next buyer exist?).

Will it accelerate or kill deals?

Both. Thesis validation that holds gives the IC paper much more conviction. Thesis validation that breaks the thesis saves the cost of full diligence on a deal that wouldn't have closed.
