About us
Probit are infrastructure planning software specialists, helping organisations make smarter, more transparent decisions about their long-term investments.
Founded in 2010 and based in Wales, UK, we've built our business around a single platform, AIM, initially branded as Asset Investment Manager.
AIM is used by utilities, energy networks, transport agencies and local authorities to plan billions of dollars in investment, balancing performance, cost, risk and sustainability at the level of individual assets.
We're a product-first company, rather than a consultancy. Our focus is on building adaptable, powerful software that supports our users, partners and regulators in making better decisions under real-world constraints.
Building a better way to plan
Probit was established with a clear conviction: that infrastructure investment decisions could, and should, be made with more clarity, rigour and confidence.
When we started out on the AIM journey, many organisations were still relying on spreadsheets, static reports, or portfolio-level models to decide how billions in capital would be spent. The process was slow, opaque, and often shaped more by assumptions than by evidence.
We believed there was a better way. So we set out to build a platform that could bring together risk, performance, cost and regulatory alignment, and optimise those decisions at the level of individual assets.
That platform is AIM. It was designed from the ground up to meet the specific challenges of capital-intensive infrastructure sectors, and has been refined and expanded ever since in collaboration with our clients, partners and regulators.
Today, AIM is used across the UK and internationally by organisations responsible for managing water, gas, roads and other critical assets. And we're still driven by the same principle that started it: better data, better models, better decisions.
Unrivalled experience in asset analytics.
Probit is a small, specialist team with deep experience in infrastructure modelling, investment planning, regulatory strategy and technical delivery. The business is managed by its founding partners.

Dr Tim Watson
Technical Director / Co-founder
An asset management specialist with over 20 year's worldwide experience in the water and asset management industry working with water utilities, councils and private consultancies, Tim has extensive experience in determining the performance and investment needs of a wide range of assets and resources, including water infrastructure, non-infrastructure, roads/highways, and fisheries. He specialises in developing strategies for utilities that help build efficient asset maintenance and operational approaches capable of implementation in a consistent and repeatable manner.
Better decisions, better outcomes
Our mission is to help infrastructure organisations make better decisions about how they invest in the assets that matter most.
We believe that smarter, more transparent decision-making leads to better infrastructure, stronger performance and lower risk, not just for operators, but for the communities and environments they serve.
Our mission is delivered through AIM, our platform built to optimise complex investment choices in real-world conditions. It gives users the speed, control and clarity they need to plan with confidence – balancing cost, performance, regulatory requirements and long-term value.
Clear thinking, practical value
We believe in building the right tools and in staying focused on what we do best. We're not a consultancy, and we don't compete with the firms who deliver frontline advisory services. Instead, we work quietly and methodically, developing, supporting and refining AIM so that our consulting partners, their clients, and the wider infrastructure community can make better decisions with confidence.
Our approach is grounded in a few simple principles:
We enable others
AIM is built to support infrastructure experts in doing their best work, not to replace them or prescribe one way of thinking.
We focus on our product
We support our consultancy partners with technical and strategic expertise, but we're not there to lead client engagements. We're all about AIM.
We focus on clarity
We believe in transparency, openness and shared understanding. Our platform, like our working style, is designed to be clear and controllable.
We go deep, not wide
We've chosen to do one thing well: build and support the most powerful investment planning platform on the market.
We build for the real world
We design for practical constraints like time, budget and regulation, and help our users to work within them effectively.
This ethos shapes the things we do: how we build, how we partner, and how we help others succeed.
