AI transformation that makes it to production.
From first pilot to a system your people use. I find where AI pays off in your company, prove it on one real process, then build and run it with your team until it is part of how the work gets done.
Production-Ready Systems with LLMs and Agents
A live Maven cohort for engineers: eight 90-minute sessions where you build LLM and agent systems that survive real traffic, real cost and real failure.
Cohort 2 is running now. Join the waitlist for the next cohort.

Your 2027 AI Plan Should Fit on One Page: Six Questions to Answer First
Most AI roadmaps are a list of projects nobody can decide on. A plan worth funding answers six linked questions on one page.
The AI System Works. So Why Is Nobody Using It?
Your AI tool passed every test, yet people still work the old way. Adoption is a change in behaviour, and it has to be led like one.
If AI Had Existed When Your Workflow Was Designed, Would It Look Like This?
Your team added AI to one step and the work arrives no sooner. The workflow itself is built on old constraints, and that is what needs redesigning.
AI Transformation Is Not Digital Transformation With a New Tool
Your AI plan looks like your last digital programme: a tool, a rollout, a go-live date. What carries over, what breaks, and what to run instead.
Your AI Pilot Saved Time. Why Didn't the Business Change?
Your AI pilot made one step faster, but the results did not move. The cause is usually the slowest step, and what you did with the time.
A Chatbot Answers. An Agent Does the Work. Here Is the Difference
Vendors call everything an agent. Here is what each step from chatbot to agent adds, and how much supervision each one needs from you.

Situational Awareness: The Decade Ahead to AGI by Leopold Aschenbrenner
