About

SpatialNext is an advisory practice — helping organisations ask the right questions before the build starts.

The AI is running. The human is present. Nobody designed what happens between them.

That gap – between machine output and the person who has to act on it – is where most AI deployments quietly fail. Not because the technology is wrong. Because nobody asked the right question before the build started:

Who is this decision for, and what does that human actually need?

I’m Matt Sheehan. AI strategist. I’ve spent 25 years at the intersection of spatial intelligence and consequential decision-making.

My thinking sits across three layers:

The sensing layer — the data infrastructure the geospatial industry spent three decades building. Satellites, IoT networks, real-time feeds covering the world at scale. Most organisations have invested heavily here.

The causal reasoning layer — systems that don’t just perceive the world but simulate it. Reasoning about cause and effect, modelling what happens if you intervene. This is arriving faster than most organisations realise.

The decision layer — the one almost nobody is designing. Which decisions the machine can settle on its own. Which ones need to reach a human, and what that human is actually authorised to do once it does. Whether the system is built to use human judgment where it matters, or skips it by default.

The third layer is where AI deployments fail. It is also where my thinking is focused.

If that layer hasn’t been designed in your organisation yet, that’s usually where the conversation starts: mattsheehan@spatialnext.io

Frameworks

The frameworks behind the thinking:

Causal Planetary Intelligence – The three-layer architecture behind everything I write: sensing, reasoning, and the human decision layer — and why the third is the one that determines whether the first two ever produce a return. Read → What is Causal PI?

The Six-Stage AI Maturity Model – Where your organisation sits on the path from AI that describes to AI that simulates — and where human authority needs to be redesigned at each stage to keep pace. View → AI Maturity Model

The Decision Architecture Diagnostic – Sorting your AI-touched decisions into what the machine can safely settle alone, and what requires protected human judgment — then, for the judgment bucket, reading where authority, thresholds, and override rights are missing or undefined. Fast, fixed-scope, and the natural first step. Available on request mattsheehan@spatialnext.io

The Conversation

Most organisations deploying AI have the sensing layer built and the reasoning layer arriving. Almost none have asked what the human is supposed to do when it does — who receives that reasoning, what they’re authorised to do with it, and whether the system is designed to use their judgment or route around it.

That question is where the conversation starts.

  • Everyone Checked the Model. Almost Nobody Checked Who Decides.

    Beyond Verification — What Responsible AI Really Demands of Human Experts — MIT Sloan Management Review (May 2026)From MIT SMR and BCG’s annual responsible-AI panel: the risk isn’t just verifying AI outputs, it’s that if junior staff never develop independent judgment and senior expertise atrophies from disuse, organizations lose the ability to govern AI systems…

    1. The Oversight Paradox: Human Control Over AI May Be ErodingWorld Economic ForumAs AI systems get better, the human reviewing their output has less first-hand command of the work — and is therefore less able to catch it when the system is wrong. Oversight and capability rise together, and that’s the trap: quality assurance requires…

  • VAR Slowed It Down. So Did I. Neither of Us Could Tell .. The Ref Still Sent Balogun Off

    He never really had a choice. Folarin Balogun collided with a Bosnia-Herzegovina defender. The on-field referee, in real time, did not send him off. Then VAR intervened. The video assistant referees in the booth pulled up slow-motion replays and still frames of the point of contact, these are the kinds of image that make any…

  • VAR Saw Everything. The Referee had the Authority. He Still Got It Wrong.

    It was the moment the technology was built for. France against Senegal, Kylian Mbappé going down in the box after a challenge from Sadio Mané. The on-field referee, Alireza Faghani, Iranian-born, now Australian-based, and one of the most decorated officials in the world, working his fourth World Cup, judged it no penalty in real time.…

  • She Reviewed Forty-Three Applications Before Lunch. She Was Allowed to Question None of Them.

    She had reviewed forty-three applications that morning. Her dashboard showed – forty-three candidate profiles assessed, ranked, and moved through the pipeline before lunch by an AI model. Sarah had been a recruiter for eleven years. her experience told her what a good hire looked like. She knew when a CV didn’t tell the whole story.…

    Paula submitted the file for the third time that week. Her credit was solid – steady income, manageable debt, a job her employer confirmed in writing was not at risk. But the AI model had flagged her file as high risk on the first pass. The second submission came back the same, as did the…

  • Zillow Offers Didn’t Fail Because Its AI Was Bad. It Failed Because the AI Was the Only One in the Room.

    Zillow Offers didn’t fail because its AI was bad. It failed because its AI was good enough that nobody thought they needed a human anymore. It was a Monday morning in February 2021. Zillow’s senior executives gathered to announce a new direction. The Zestimate — their AI valuation model — was accurate enough, they decided,…

She has watched the sensing layer get built from the ground up — from 30-metre Landsat imagery to sub-metre daily revisit, from manual digitising to AI-powered change detection at planetary scale.…
