Today I’m in Pyeongtaek. At the 'Kyungdong Human Resources Development Institute', I delivered a full-day 'B2B Sales' training for the B2B sales employees of 'Kyungdong Navien'. Kyungdong has moved on from the days of supplying only boilers to builders. It now sells "almost everything that goes into a home" as a package: ① boilers + ② ventilation air purifiers + ③ dehumidifying ventilation air purifiers + ④ kitchen appliances (Navien Magic) + ⑤ home network systems + ⑥ room-by-room control systems + ⑦ cascade systems + ⑧ sleep mats (hot water). 


The value proposition was especially complex, so I simply built a web app with Claude Cowork. Building it live during the session really impressed them. They said it was their first sales training in 14 years. One manager sent this feedback on KakaoTalk: "There were so many moments today when it all clicked. It was extremely useful." All of our training this year will work this way. Love it!
