How can we help you?

Our Services

End-to-End Systems

We undertake and advise on large end-to-end system design. From hardware and sensors to big data analysis.

Data Science

Data wrangling, processing, analysis, machine learning and visualisation as advice or a service.

Internet Of Things

From hands-on sensor and LoRa node hardware and firmware design to back-end big data processing.


We specialise in the practical deployment of current techniques for AI within larger solutions for results today.

Supporting Startup

Come talk to us. Tea and cake buys a couple of hours advice. We will help you get things right first time, or as 'virtual CTO'.

Pathfinder Development

We love short projects to prove what can be done. We have soldered hardware, prototyped databases with AI, and built mobile apps and web.

Merger and Aquisition

Technical due dilligence as a service for investors & acquirers, and exit readiness for sellers. Clear conclusions for non-technical audience.

Software Operability

We know how to build, and have built and deployed software that really is 99.9% or 99.999% reliable, and operable, and resilliant. Ask us how.

How do we work?

If you think we can help, contact us.

We will (if practical) arrange to meet and chat.
Face to face works much better than electronic. No fee at this stage.

We’ll talk about your issues for an hour or two – both immediate and any context.
In some cases we have come up with an outline solution at this stage. Still no fee.

We’ll discuss whether we can help you, and how. Still no fee.

We’ll agree terms if we want to carry on working together.

About Us

Mandrel Systems is a long standing, bespoke Cambridge engineering company originally formed in 1999 with a focus on processing difficult real world data. We expanded to develop our edge in understanding big systems end-to-end. Some of our solutions use leading edge technology, others revive and update techniques from 40 years ago. We apply intelligent processing to turn data into useful information. We make systems that work, and keep on working. Markets include Telco (OSS and BSS), Retail (first UK shopping app - Tesco), Education (, Transportation (ship fuel optimisation).

We are currently working on projects incorporating AI, Big Data, IoT in Environmental, Telco and Shipping applications.
