Built by risk professionals

BowTie Risk was developed by professional risk consultants frustrated with tools that were too complex, prohibitively expensive, or simply not built for Apple devices. Built in Australia.

The bowtie methodology has been a cornerstone of professional risk management for decades — used in aviation, healthcare, energy and government. BowTie Risk brings that rigour to iPhone, iPad and Mac in an interface anyone can use.

Every design decision — from the cognitive science behind the layout to the offline-first architecture — reflects real-world risk assessment needs.

What's a bowtie diagram?

It's a simple visual map of risk — the event that could occur sits in the middle, with what could cause it on the left and what could go wrong if it happens on the right. Controls sit in between. At a glance, you can see your full picture of the risk.

Build a complete BowTie with AI.

BowTie Risk has a built-in AI workflow that works with any AI tool — ChatGPT, Claude, Gemini or any other. No subscriptions, no lock-in. You stay in control.

Step 2

Take it to your AI

Built on cognitive science

Miller's Law

In 1956, psychologist George Miller demonstrated that the human brain can only hold 7 (±2) items in working memory at once. Overload that limit and decision-making breaks down.

BowTie Risk is designed around this principle. The bowtie structure deliberately organises complex risk information into focused, bounded groups — threats on one side, consequences on the other — so your brain can process each element clearly without becoming overwhelmed.

Chunked information

Threats, controls and consequences are each grouped separately, keeping each chunk within cognitive limits.

Visual clarity over data overload

A single bowtie replaces pages of text — letting you see the full risk picture at a glance, not wade through it.

Better decisions under pressure

When risks are structured to match how the brain works, teams respond faster and more accurately in critical situations.
