Yesterday I delivered B2B sales training for the Hyosung Information Systems sales team.
But partway through the session, something unexpected happened.
We built an app for the trainees, live, in the room.
I found it hard to believe at first, but with AI’s help it was truly possible.
In B2B sales, one question comes up again and again.
"Why is it more expensive than HP or Dell?
Why is it so expensive?" That is price pushback.
This reaction happens because customers judge by purchase price alone, without seeing the full total cost of ownership (TCO).
Explaining in words wasn’t persuasive enough, so I decided the only way to convince people was to show them the numbers.
So the night before the training, I used Claude Cowork to code a TCO calculator web app myself.
I built it so that once you enter equipment quantity, maintenance cycle, and downtime risk, it automatically calculates the real cost difference versus competitors.
But the most interesting thing happened in the middle of the session.
While teaching, I was talking with one trainee
Looking at it, I could see where the app needed improvement.
I recorded that conversation on the spot, turned it into a transcript, and handed it to Claude with instructions to revise the app.
While I kept teaching, Claude kept revising the app, and I could share the updated version in the group chat right in the middle of the session.
Then one participant asked a great question.
"These numbers look so realistic. Where did you get them all?
Did you know?" I had to answer honestly.
"I didn’t know that either.
I left it to the AI and it filled them in on its own." This training made three things clear to me.
First, instructors can now become real-time developers.
You can build a tool on the spot that reflects trainee feedback right during the session.
Second, the output of the training is completely different.
Trainees leave with a practical tool they can use at work tomorrow, not just slide decks.
Third, AI accurately understands the language of field experts.
Automatically generating realistic, industry-appropriate figures from a single transcript was more than simple automation.
This experience clarified where I am taking my training this year.
Going forward, my goal is to build a custom AI web app for the trainees in real time while I teach.
Corporate training is already moving beyond knowledge transfer to building tools people can use on the job right away.
We will keep refining this new style of training so that more companies can experience it.
