The Smart Detractor Failure Audit corrects a selection effect in fundraising and advice. Blomfield observes that investors who agree with a company's past approach are more likely to invest, while those who think it is misguided walk away. The resulting board can become an echo chamber that encourages more of the same. His proposed countermeasure is deliberate: identify the smartest investors, advisers, or founders available and ask why they think the business will fail. The founder then examines the underlying mechanisms rather than dismissing the answer or seeking reassurance from supporters. This is not a vote and does not give detractors control. It is a structured search for overlooked constraints, followed by investigation, mitigation, and a test that could show whether the concern is material.
Origin
Reflecting on Monzo's investor dynamics, Blomfield says he hopes to seek out smart investors, advisers, or founders who can explain why a business may fail, rather than listening only to people who think it is brilliant. Extracted from The Diary of a CEO.
Core principles
- 01Capital selection can filter out disagreement
- 02Supportive stakeholders may reinforce the strategy that attracted them
- 03Credible doubt contains information even when its conclusion is wrong
- 04The task is to test failure mechanisms, not defend founder identity
How to run it
- 1
Identify credible dissent
Choose a small set of experienced people who understand the business but do not share its core assumptions.
Pro tip Prefer informed doubters over indiscriminate critics.
- 2
Ask for the failure case
Ask each person directly why the business will fail and what sequence of events would produce that outcome.
Watch out Do not turn the conversation into a pitch or rebuttal.
- 3
Extract the mechanism
Convert each answer into a specific causal claim that can be examined, such as costs growing faster than revenue.
Pro tip Discard insults and retain claims with observable inputs and consequences.
- 4
Test the strongest risks
Gather evidence that supports or weakens each material claim and compare it with the assumptions in the current plan.
Watch out Do not use confidence from supportive investors as evidence against the risk.
- 5
Mitigate or monitor
Change the plan where the risk is credible, or define an indicator and review date where uncertainty remains.
Pro tip Record what evidence would trigger a strategic change.
In the wild
Blomfield describes how investors who liked Monzo's approach selected into the company, while sceptics invested elsewhere. In hindsight, he believes deliberately asking credible doubters why the business could fail might have surfaced neglected problems earlier.
→ The audit would add structured dissent to a board naturally selected for support.
Common mistakes
Consulting only supporters
People who selected into the company because they liked its past choices may reinforce the same blind spots.
Confusing doubters with haters
The useful input is a credible failure mechanism, not hostility or generic pessimism.
Collecting criticism without action
A useful audit ends with evidence, mitigation, or a monitored trigger rather than a list of worries.
Is it for you?
Best for
It is best for founders whose boards, investors, or advisers largely supported the choices that produced the current strategy.
Not ideal for
It is not ideal as an unfiltered invitation to hostile commentary from people without relevant evidence or judgement.
