About AUDITSU

We put AI to work inside regulated businesses and leave a record that proves it behaves. Accessibility is one of the services on that record. AUDITSU is built in Leeds by Jason Crispin and Simon Milner.

How it started

Born from frustration.

  1. 2023

    The frustration

    Jason built a mobile app that used AI to write and illustrate children's stories. Getting its accessibility right was the frustrating part.

  2. 2024

    The pivot

    He turned to that problem: helping teams meet accessibility standards, and show that they have.

  3. Today

    Live

    AUDITSU launched in April 2026. Accessibility is on general sale, and document sign-off is in early use.

What it became

  1. We built an accessibility product.
  2. We found the record underneath it, and filed a patent for it.
  3. Now we put AI to work for regulated teams, and prove it.
How we work

Software helps. A person decides.

A named person signs it off

Your team, your software or an AI can do the work. Whether it meets the standard is a judgement a named person makes, and AUDITSU records who made it and when. Our software does not make that call for you.

Proof should stay current

A report describes the day it was written. We build records that update as the work changes, so what you show someone is still true.

We say what is live, and what is not

We tell you plainly what the product does today, what is in early use, and what is still a conversation. If the honest answer is that we are not the right fit, we say so.

Built for people

The A in our logo carries 人 (ren), the character for “person”. Compliance is about people: the ones who use what you build, and the ones who sign it off.

The people

Simon and Jason

You deal with Simon and Jason from the first call. One engineer sits inside your team, full time, for the four weeks.

Jason Crispin

Founder

Jason Crispin is the Founder of AUDITSU. He built the company from an accessibility product into a firm that puts AI to work inside regulated businesses and leaves a record that proves it behaves, and he has led every customer relationship it has.

As Founder, Jason sets the company's direction and commercial model and owns the customer side of a deployment: what the job is, what it is worth, and that it lands. He is on the first call and every one after, working alongside Simon Milner on scope, delivery and the record the customer keeps.

Before AUDITSU, Jason had multiple startup exits and spent more than twenty years in sales, where he personally won and delivered contracts worth £12.3 million a year inside a billion-dollar company. That is the discipline he brings to a deployment: a clear scope, a fixed timeline, and an outcome the buyer can put in front of their board.

Key focus areas

  • Company direction, commercial model and pricing
  • Customer relationships, from first call to signed-off record
  • Scoping and delivering deployments on a fixed timeline
  • Making AI provable to compliance teams, auditors and boards
  • Fundraising and partnerships

Simon Milner

Founding Architect

Simon Milner is the Founding Architect of AUDITSU. He designed the record that sits under a deployment: the system that checks what an AI is allowed to do before it does it, records the decision, and lets anyone replay the history later. It is the subject of the company's patent application.

As Founding Architect, Simon owns the technical side of a deployment: how the job is built in the customer's codebase, how the check is wired into it, and what the customer is left running. He works alongside Jason Crispin from the first call, and he sets the engineering standard the company hires to.

Simon has spent more than thirty years turning new technology into products, twenty-five of them in Silicon Valley. He was employee number 30 at MMC Networks, which created the network processor category, listed on Nasdaq and was acquired for $4.5 billion. He co-founded Candlestick Networks, sold to Nortel, spent nine years as Vice President and General Manager at Marvell Semiconductor, and founded Petzila, whose connected pet camera sold through Best Buy, Petco, Walmart and Amazon before it was acquired by Wagz.

He holds a PhD in digital signal processing and a first-class engineering degree, has published 18 academic papers, and started out as an air radar technician in the Royal Air Force.

Key focus areas

  • Architecture of the record and the check behind a deployment
  • Technical scope and delivery of deployments in the customer's codebase
  • Engineering standards, hiring and handover
  • Patent and research
  • Deep technology: signal processing, networking, embedded systems

Our values

Relentless Progress

We move with urgency. Speed matters, but outcomes matter more.

Full Ownership

No excuses. We own problems end-to-end and execute without waiting.

First-Principles Innovation

We question everything. We build what works, not what's always been done.

Simplicity

Complexity is the enemy. We eliminate waste to deliver clean, high-impact solutions.
