O'Leary describes a three-stage sequence he uses to judge entrepreneurs. First, the founder must communicate the big idea quickly enough that the listener understands the product and why it matters, ideally within 90 seconds. Second, the founder must explain why they or their team are equipped to execute: relevant industry knowledge, experience with a competitor, or lessons from previous failed attempts can provide that evidence. Third, the founder must know the numbers, including market size, growth, gross margin, competitive landscape, and expected break-even timing. The stages compound: an attractive idea is common, an able operator reduces execution risk, and numerical command shows that the operator understands the language of business. Missing the third stage can negate success in the first two.

Origin

O'Leary presents the test as a pattern learned from decades of hearing pitches and investing on Shark Tank and Dragon's Den.

Core principles

  • 01Communicate the big idea quickly
  • 02Connect the opportunity to operator credibility
  • 03Know the commercial numbers without prompting
  • 04Treat all three parts as necessary

How to run it

  1. 1

    Land the big idea

    Explain the product, customer, and central value clearly within 90 seconds. The listener should understand what you are asking them to consider.

    Pro tip Remove detail that does not help the listener grasp the opportunity.

    Watch out A polished presentation cannot rescue an unclear idea.

  2. 2

    Prove operator fit

    Show why you or the team can turn the idea into a business. Use relevant work, sector knowledge, or lessons from prior attempts as evidence.

    Watch out Do not assume enthusiasm alone demonstrates execution ability.

  3. 3

    Demonstrate numerical command

    Answer the core commercial questions: market size, growth, gross margin, competitors, and the month you expect to break even. Bring a finance-capable teammate if necessary.

    Pro tip Practice answering each number directly before adding context.

    Watch out Not knowing the numbers can erase the credibility built in the first two stages.

In the wild

A founder with relevant failed attempts

O'Leary gives the example of a founder who has tried three times, failed, and can explain what those failures taught them. That history can support the second stage by showing why this operator is now better equipped to execute.

Prior failure becomes evidence of operator fit rather than an unexplained liability.

Common mistakes

Treating the idea as enough

O'Leary calls great ideas common; the pitch still needs an operator case and commercial numbers.

Guessing at break-even

The framework expects a specific month and command of the assumptions behind it.

Is it for you?

Best for

It is best for founders preparing to ask investors, lenders, or partners for support.

Not ideal for

It is not ideal as a substitute for deeper diligence after the initial pitch succeeds.
