Case Study: when a salesperson builds his own AI tools
Three two-hour sessions, and a Claude Code plugin now circulating in his team
Situation
Charles is an account executive at a software company. He was already using AI every day, but as a consumer of the tools his working environment provided: his practice stopped where those tools stopped. His request was to be more efficient day to day, and his view of Claude Code before starting was blunt, it was "complicated". The failure criterion he set himself during framing left no ambiguity: "Claude Code is useless and I don't use it".
Objective
Move an AI user from consumer to builder, by producing not a set of course slides but a tool genuinely used in his job, on his real accounts and his real tools, and autonomous enough to circulate in his team without the trainer.

Process
Session 1: build
Setting up the workspace architecture, writing the CLAUDE.md file, MCP connections and first exercises. A two-hour session by video call.
Session 2: prospect
LinkedIn signals through Apify, mapping of the accounts in his territory and preparation of client meetings. A two-hour session by video call.
Session 3: industrialise
Moving from one-off uses to a packaged, installable Claude Code plugin, with skills, agents and connectors, carrying its own onboarding agent. A two-hour session, followed by a question-and-answer session to unblock the remaining points.
Results
A plugin in production, finished by the participant alone between session 3 and the following week
One fellow account executive completed the entire onboarding and installed the plugin with no involvement from MAIjin, 6 days after the coaching ended
2 spontaneous referrals in 3 days, with both meetings booked
634 accounts in his territory identified by an agent the participant built himself, 33 of them analysed in depth
Design system enriched and client presentations generated automatically
SwissNova certificate issued at the end of the programme
A lesson kept and folded into our method: audit the IT constraints of the company before implementation, not after
