Decisions under uncertainty

We price probability.

Zero Theorem builds technology specific to making decisions under uncertainty. We take no view on direction and commit capital only when a market misprices an outcome, so every action we make moves the price closer to the true probability.

Corporate consultancy

We bring the probability methods we use in markets to the decisions inside your business, from pricing and capital allocation to the AI systems that act on them.

Decision models

We develop expected-value models for pricing, bidding and optimising capital allocation.

Response calibration

We calibrate response systems to population tendencies that deviate from theoretical distributions.

AI systems

We design agentic workflows that automate research, identify mispricing, action response and manage risk.

Privacy Policy

This policy explains how Zero Theorem Pty Ltd (ABN 30 642 102 663) ("Zero Theorem", "we", "us" or "our") handles personal information in connection with zerotheorem.com and when you contact us. We aim to handle personal information in line with the Australian Privacy Principles.

What we collect

The site has no accounts, forms, comments, advertising or analytics. It does not set cookies or use tracking technologies. We receive personal information only in these ways:

When you visit. Our hosting provider automatically receives standard request information, such as your IP address, browser type, the page requested and the time of the request. It is used to deliver the site and keep it secure, not to identify you.
Fonts. The site loads its typefaces from Google Fonts, so your browser connects to Google's servers, which receive your IP address and browser details. Google's handling of that information is described at policies.google.com/privacy.
When you contact us. If you email us, we receive your email address and anything you include in your message.

How we use it

We use personal information to respond to enquiries, to provide and manage consultancy engagements, to operate and secure the site, and to meet our legal obligations. We do not sell personal information or use it for advertising.

Disclosure and overseas storage

We use service providers to run the site and our email: Vercel Inc. hosts the site, and Google LLC provides Google Fonts and our email (Google Workspace). These providers may store or process information outside Australia, including in the United States. Otherwise, we disclose personal information only with your consent or where the law requires or permits it.

Security and retention

We take reasonable steps to protect personal information from misuse, interference, loss and unauthorised access, modification or disclosure. We keep correspondence only for as long as we need it for the purpose it was provided, or as the law requires.

Access and correction

You can ask to access or correct the personal information we hold about you by emailing us. We will respond within a reasonable time.
