I've been in sales my whole working life. Shop floor, business development, field sales, sales management, and now building the tools I wish I'd had along the way. This is the honest version of how rAInmaker came to exist, not the tidied-up pitch version.
The role-play I couldn't stand
I've sat through more sales training courses than I can count. MEDDIC, SPIN, objection handling, qualifying questions, the lot. A day in a room, a good trainer on stage, a workbook to take home, commitments to use what you'd just learned. And then, always, the role-play. A scripted scenario, someone pretending to be a customer, walking you toward the answer they already knew you were supposed to give. I found it almost useless, and I don't think I was alone. You'd nod along, do the day, go back to your desk, and a week later you'd forgotten most of it and slipped back into old habits. I did that more times than I'd like to admit.
The car park
The interaction that actually changed me happened nowhere near a training room. I was an account executive, early in my career, doing accompanied visits with my sales manager, a straightforward, sharp guy who knew his stuff. We were meant to do about ten site visits that day. We did two.
He pulled the car into a car park and, not unkindly but very bluntly, told me I hadn't prepared for a single one of those visits and there was no point wasting his time doing any more that day. That was it. No shouting, no lecture. Just the truth, said plainly, at the exact moment it would land.
The following week I actually prepared. Meetings booked ahead, materials ready, a real plan for how I'd handle each conversation. The difference was obvious, not perfect, nobody gets there in a week, but obvious. And he noticed, and said so. That's the whole model. A blunt, honest read, at the moment it's actually useful, from someone who isn't trying to make you feel good, just better.
The manager who challenged everything
Around the same time I had another manager, my regional business manager, a genuinely good guy who was never forceful or aggressive. What he was good at was challenging my assumptions. I'd get comfortable doing something a certain way because it had worked once, and he'd just ask, plainly, why I'd done it that way, or what I might be missing. Simple questions, asked at the right time, about a real situation I was actually in. Not a hypothetical. That combination, blunt and kind, aimed at something real, is the pattern I kept running into throughout my career whenever actual behaviour change happened.
I eventually became a sales manager myself, running a team of nine in what was then the worst-performing region in the company. Using that same approach, we got to mid-table inside about eighteen months. One rep who was close to being let go ended up nominated for the company's sales award after a bit of honest, well-timed coaching. That wasn't magic. It was just someone telling him the truth about his deals at the right moment, consistently.
Cab coaching, and a second version of the same idea
My career took a turn after a redundancy, half the sales team went at once, and I moved into technology sales, fleet telematics first, then vehicle camera systems and risk management. Different industry, same underlying pattern. Fleet companies trying to cut collisions and fuel waste had been using "in-cab coaching" for years. An alert fires the moment a driver does something risky, at the exact point it happens, not in a classroom weeks later. Done properly, with real follow-up, it worked. Done badly, it didn't. The principle was identical to what I'd learned in that car park. The right correction, delivered at the moment it's actually relevant, beats almost anything delivered later.
Where AI came in
I started using AI tools the way most people did at first, as a slightly better search engine. It was moving from ChatGPT to Claude that changed how I actually used it. Not as a lookup tool, but as something that could hold context, reason through a real situation, and apply judgement rather than just retrieve an answer. That's when the idea clicked. The thing that had actually changed my behaviour, twice, in two different industries, was a blunt, well-timed challenge from someone who knew what they were doing, applied to a real situation as it happened. Why couldn't that exist for every seller, on every real deal, rather than once a year in a training room?
That's what rAInmaker is built to be. Not a chatbot that flatters your draft, and not a scripted role-play. Something that looks at your actual deal, your actual email, your actual call, and gives you the same kind of honest, well-timed read that changed how I sold. It's not always right. It doesn't need to be. The challenge itself, at the right moment, is what makes you think differently. That's where real, lasting change actually comes from, not from being told you did great.
Why a Claude Skill, and not another app
People sometimes ask why this is a Skill rather than a piece of software, since anyone can build a Skill themselves. That's true, and I'm not precious about it. I'm not a developer. I'm a sales professional who's spent two decades learning what actually works, and I built this from that experience rather than from a spec sheet.
My wife and I grow a lot of our own fruit and vegetables. We wash it, chop it, cook it, while plenty of people would ask why we'd bother when the supermarket sells it already done. There's a genuinely huge market for vegetables that come pre-washed and pre-chopped, and people happily pay a premium for exactly that convenience. We'd never buy those ourselves, but plenty of people do, and they're not wrong to. Some people genuinely want to build their own version of something like rAInmaker, and they should. But most people don't want to spend the time working out the right prompts, rules and guardrails to make an AI coach actually behave like a good sales manager instead of a yes-machine. They just want the finished thing, built properly, by someone who's actually done the job it's coaching them on.
Why £59 once, not another subscription
When I first floated the idea of a one-time £59 price for a Claude Skill, the general advice was that it was far too high, that Skills should sell for a few pounds at most or nobody would buy them. I understand the logic. I just don't agree with it, once you look at what people are actually comparing it to.
Plenty of sales tools charge £10 to £20 a month, which adds up to hundreds of pounds a year, every year, for as long as you keep paying. I got tired of that model in my own life, same as most people have. A subscription for every service, and the moment you stop using one, that's money gone for nothing.
And if a Skill is actually built well, learning your business, your writing style, your product knowledge, rather than depending on a vendor pushing updates to a server, it keeps delivering value without needing a monthly bill to justify its own existence. That's the whole argument for one-time pricing. Charge fairly for what you built, once, and let people keep it. It's also why Lite, the free version, exists, so you can try the coaching properly before you spend anything, rather than taking my word for it.
Where this goes next
rAInmaker is the first Skill I've built this way, but it won't be the last. I've spent a career in sales and picked up a fair amount of marketing knowledge alongside it, and the plan for skillfAIre is more Skills built to the same standard, made by someone who's actually done the job, tested properly, and sold once rather than rented forever. Feedback shapes all of it. If you've used rAInmaker and have thoughts on what's working or what isn't, I want to hear them.
