Executive & founder coaching
One-to-one work with senior people who don't have time for a syllabus. We start where you actually spend your week and build prompts and habits from there.
Boffin Hub · Senior Claude trainer
Senior-level Claude. For founders, executives, and the teams they trust.
Most teams meet Claude through a demo and a clever prompt. Senior teams need more: real fluency in prompt design, judgement about what to delegate, and workflows that survive contact with a real working week. That's what the training builds.
01
Tailored Focus
One-to-one and small-cohort coaching, designed around how senior teams actually work.
02
Practical Fluency
Sharp prompt design and sound LLM judgement. Skills that hold up midweek, not just in a demo.
03
Executive-led
Bespoke programmes for founders, executives, and the functions they lead.
What I do
Three places I tend to be useful.
Engagements rarely fit a neat box, but most lean on one of these three. Programmes are bespoke; the underlying craft is the same.
02
Prompt craft & LLM judgement
The unglamorous middle layer: sharpening intent into prompts, building a sense of when Claude is the right tool, and when the human brain in the room still wins.
03
Bespoke enterprise programmes
Programmes shaped around the team you have: your tools, your tone, your constraints. Workshops, cohort coaching, and follow-through that actually sticks.

The interesting work isn't the model.— On training senior teams to use Claude well
It's the moment a team stops asking
and starts using.
Who I work with
Senior teams. And the people who lead them.
Most engagements are with founders, executive teams, and the functional leaders they bring with them. The brief varies. The need for something practical doesn't.

The arc of it
From demo curiosity to daily fluency.
Every team follows a version of this line. My job is the slope, and getting you through the dip in the middle. Scroll and it draws itself.
How we'd work together
A simple rhythm, tailored to your team.
Shaped around your team rather than a fixed syllabus. Most engagements move through these four steps.
01
An honest conversation
We start with a call: what your team does, where Claude might earn its keep, and where it almost certainly shouldn't.
02
A programme that fits
Sessions designed around the team you have: live workshops, small-group coaching, async materials, or some combination.
03
Live, hands-on training
We work with Claude on real material from your team. Prompts, workflows, edge cases. Nothing rehearsed.
04
Follow-through
The bit most training skips. We come back to the workflows after they meet real life, refine what's working, and quietly retire what isn't.
Session cards
The deck we work through.
Five session themes, dealt in whatever order your team needs. Every programme uses them differently.

re: whether this is for you
Hello,
If your team already gets solid work out of Claude every day, you don't need me. Close the tab, no hard feelings.
Most teams I meet aren't there yet. The licences are paid for, two or three people are keen, and the results are patchy. Nobody says this out loud. That gap is where I spend my working week, on your documents and your deadlines rather than generic exercises.
If you're weighing it up, send a short note about the problem sitting in front of you. I'll tell you straight whether training will move it. If it won't, I'll say so and point you at something that will.
Warmly,
P.S. You'll get a reply from me, not an assistant.
Get in touch
Let's see if it's a fit.
A short note is plenty. I'll come back to you within a couple of working days with whether I can help. If I can't, I'll suggest someone who can.
Thank you.
Your note is on its way. I'll come back to you within a couple of working days.
