You have modelled the decision internally. Strategised around it with your co-founder. Presented a version of it to your investors.


You have not validated it with the people who would prove you wrong.


Your champion loves the product. Procurement has not been in the room yet. Your demo margins look strong. You have not modelled production at scale. Your pilot succeeded. Enterprise deployment hit a compliance wall nobody saw coming. Your regulatory posture feels solid. Your enterprise buyer’s security questionnaire has not arrived yet.

Why smart founders carry Assumption Debt®.

Why smart founders carry Assumption Debt®.

Founders are not irrational. They are systematically biased toward the assumptions that got them funded in the first place.


Confirmation bias makes you seek evidence that validates what you already believe. Every customer conversation that goes well reinforces the assumptions underneath it. The conversations that would prove you wrong never get scheduled.


Commitment bias makes you double down on decisions already made rather than question the assumptions underneath them. The further along you are, the harder it becomes to see which beliefs are load-bearing and which are comfortable fictions.


Both biases are stronger, not weaker, in founders who are intelligent, experienced, and moving fast.

What have you not tested that you are about to commit the runway to?

The Assumption Crucible™ Event Audit.

£4,750.

Your pilot worked. The deal is stuck. Map what is actually blocking it in seven days. Or you are approaching a Series A raise, or a board review, and need to know which assumptions will not survive external scrutiny. A written Assumption Debt® map delivered within 24 hours of the second session. Fee deducted if you proceed to the full engagement.

The Assumption Crucible™ Engagement.

£15,000.

Four weeks. For post-seed founders burning £75k to £110k a month with 8 to 18 months runway, maximum vulnerability months 7 to 11 post-funding, facing a major strategic commitment. Ten to fifteen stakeholder conversations with the people who would prove your assumptions wrong. A written decision memo. Not a slide deck. A decision.

Founding Design Partners.

Founding Design Partners.

Assumption Crucible™ is currently accepting five Founding Design Partners across both engagements. These are AI founders in regulated markets who want early access to the methodology and are willing to provide structured feedback on the engagement process in return.

This is not a case study request. There is no public attribution. No marketing asset. Just honest structured feedback on what worked, what did not, and how the methodology can be sharpened. You act as a design partner helping build something better. That feedback stays internal and feeds directly into the next iteration of the framework.

If you are approaching a major strategic commitment and want to explore whether a Founding Design Partner arrangement makes sense for your situation, start with a qualification call.

Who this is for.

Who this is for.

This works for AI founders in regulated markets who are approaching a major strategic commitment or a specific event, a board meeting, a raise, a stalled deal, or a regulatory deadline, in the next 60 to 90 days. Fundraising. Market entry. A senior commercial hire. Enterprise positioning.


If you are burning more than £15k a month and about to make a decision you cannot easily reverse, this is worth a conversation.


If you are pre-revenue, have no team in place, or are more than 18 months from your next major commitment or trigger event, this is not the right moment.


Every engagement starts with a 30 minute qualification call to confirm the fit is right on both sides.
