From the founder

I used to fix the machine. Now I fix the process.

Fifteen years in engineering in the UK. Engineering management and automation, at Amazon Robotics and Jaguar Land Rover, with nearly a decade of it in the car industry.

Then consulting. Personal at first, now business, AI, automation and software. I still ask the question underneath the question. It's the most useful thing I brought across.

I work inside the largest community of AI entrepreneurs and custom software developers in the world. That's where the developers on our bench come from, and where our methods get tested before a client sees them.

We build custom software and AI systems that take the admin out of energy, construction and industrial businesses in the UK and the US. I scope every build myself. If it's not a fit, I'll say so on the first call.

About 25 Tera Watts

The planet runs on about 25 terawatts. We work on the part that's wasted.

The name is the number. Twenty to twenty-five terawatts is roughly what human civilisation draws, all day, every day, and the 25 is also a twenty-five-year horizon for making energy go further, the electrical kind and the human kind.

25 Tera Watts is a UK AI consultancy and custom software developer. We build bespoke business software, AI automation and operations systems that remove admin from energy, construction and manufacturing companies, then hand the client the code, the data and the accounts.

6 Nov 2026 · 4 min readWe have seen the demos. Can we watch one whole job?

A finance director refused to sign off a build last week, and he was right to. He had been shown every part of it working. He had never once watched a single job go in at one end and come out the other.

I spent months in conversations with a client about what their data could tell them. We spoke again this week. They have built the whole thing in house, and it is better than what I had in mind.

Three directors asked me last week whether moving to a new platform means starting from scratch. The honest answer is that your content comes with you and almost nothing else does.
