I'm Mark Walker. Three-time CRO at Attest, Pion (Student Beans), and native, ex Head of Growth at Eventbrite. I help B2B founders and revenue leaders rebuild their GTM teams around what AI can actually do now, not what the vendors are promising next quarter.
Most GTM teams need one of three things right now. A clearer view of what AI changes about how they sell. Someone to build the bits the team can't. Or a programme that builds the capability inside the company so they stop renting it from people like me.
A two-stage engagement that gives you a board-ready view of where AI changes your GTM motion. Stage 1 is a one-to-two-week deep dive diagnostic from £3k. Stage 2 is ongoing strategic support, if it makes sense.
The AI tooling your team actually needs, built and shipped. Skills, agents, workflows, integrations, internal apps. Scoped per project. I build it, your team owns it on day one.
Six months. I train your designated AI Champion into a fully-functioning internal GTM Engineer, plus upskill the wider team. The capability stays after I leave. This is the offer I get asked about most.
Most engagements end up being a blend. If you're not sure, book a call and we'll work it out in 30 minutes.
Start with the strategic consultancy. The two-week diagnostic gives you a prioritised list of AI projects tied to commercial outcomes, then ongoing support if it makes sense.
Hands-on implementation. Scoped per project. Custom skills, agents, internal workflows. I ship it, your team owns it.
The GTM Engineer coaching programme. Six months. One of your people becomes the in-house engineer. Cheaper than hiring, faster than training from scratch.
I've spent 20+ years building and running revenue teams. CRO three times. Head of Growth at Eventbrite before that. I've built the engine, hired the team, and missed the number. I know which playbook bits AI actually rewrites and which bits it leaves alone.
I run AI GTM Studio solo. No bench, no juniors, no farmed-out delivery. Every engagement is me. That's the trade. You get fewer hours from a more experienced operator who's done the job, not a deck team that hasn't.
I don't pretend to be a fit for everyone. The patterns below cover roughly 90% of what I take on.

You probably don't, and that's the point of the first call. In 30 minutes we'll work out whether you need clarity (consultancy), capability (implementation), or capability that stays (coaching). Lots of engagements blend two.
Yes, and most do. A typical path: a strategic consultancy engagement to get the commercial picture right (diagnostic plus ongoing support), with builds shipped under implementation as they're needed and the coaching programme alongside if there's a Champion in the team.
Me. There is no team behind the curtain. If you sign with AI GTM Studio, you work with me. That's the upside and the constraint. It also means there are only so many engagements I can run at a time.
Thirty minutes. No deck. Tell me what's broken or what you're trying to build. I'll tell you whether one of the three solutions fits, whether something else does, or whether I'd send you elsewhere. You'll leave the call with an opinion either way.
Pricing sits on each solution page so you can decide before we speak. Strategic consultancy from £3k for the diagnostic, ongoing support from £3k per month. Hands-on implementation from £8k per scoped build. GTM Engineer coaching at £45k for the six-month programme. No retainer creep, no hidden fees.
Yes. I'm also building Inklined, a thought-leadership and call-intelligence product for fractional execs and solopreneurs. I'm building both AI GTM Studio and Inklined in the open. The work I do for clients makes the product better, and the product work makes the consulting better. They feed each other.
Tell me what's broken or what you're trying to build. I'll tell you whether I can help, or whether someone else can do it better. You'll leave with a clearer view of what to do next, either way.
